[![npm](https://img.shields.io/npm/v/@cloudflare/kv-asset-handler.svg)](https://www.npmjs.com/package/@cloudflare/kv-asset-handler)  
[![Run npm tests](https://github.com/cloudflare/kv-asset-handler/actions/workflows/test.yml/badge.svg)](https://github.com/cloudflare/kv-asset-handler/actions/workflows/test.yml)  
[![Lint Markdown](https://github.com/cloudflare/kv-asset-handler/actions/workflows/lint.yml/badge.svg)](https://github.com/cloudflare/kv-asset-handler/actions/workflows/lint.yml)  
`kv-asset-handler` is an open-source library for managing the retrieval of static assets from [Workers KV](https://developers.cloudflare.com/workers/runtime-apis/kv) inside of a [Cloudflare Workers](https://workers.dev) function. `kv-asset-handler` is designed for use with [Workers Sites](https://developers.cloudflare.com/workers/platform/sites), a feature included in [Wrangler](https://github.com/cloudflare/wrangler), our command-line tool for deploying Workers projects.
`kv-asset-handler` runs as part of a Cloudflare Workers function, so it allows you to customize _how_ and _when_ your static assets are loaded, as well as customize how those assets behave before they're sent to the client.
Most users and sites will not need these customizations, and just want to serve their statically built applications. For that simple use-case, you can check out [Cloudflare Pages](https://pages.cloudflare.com), our batteries-included approach to deploying static sites on Cloudflare's edge network. Workers Sites was designed as a precursor to Cloudflare Pages, so check out Pages if you just want to deploy your static site without any special customizations!
For users who _do_ want to customize their assets, and want to build complex experiences on top of their static assets, `kv-asset-handler` (and the default [Workers Sites template](https://github.com/cloudflare/worker-sites-template), which is provided for use with Wrangler + Workers Sites) allows you to customize caching behavior, headers, and anything else about how your Workers function loads the static assets for your site stored in Workers KV.
The Cloudflare Workers Discord server is an active place where Workers users get help, share feedback, and collaborate on making our platform better. The `#workers` channel in particular is a great place to chat about `kv-asset-handler`, and building cool experiences for your users using these tools! If you have questions, want to share what you're working on, or give feedback, [join us in Discord and say hello](https://discord.cloudflare.com)!

## Installation
Add this package to your `package.json` by running this in the root of your
project's directory:
```
npm i @cloudflare/kv-asset-handler
```
## Usage
This package was designed to work with [Worker Sites](https://workers.cloudflare.com/sites).
## `getAssetFromKV`
getAssetFromKV(Evt) => Promise<Response>
`getAssetFromKV` is an async function that takes an `Evt` object (containing a `Request` and a [`waitUntil`](https://developers.cloudflare.com/workers/runtime-apis/fetch-event#waituntil)) and returns a `Response` object if the request matches an asset in KV, otherwise it will throw a `KVError`.
#### Example
This example checks for the existence of a value in KV, and returns it if it's there, and returns a 404 if it is not. It also serves index.html from `/`.
### Return
`getAssetFromKV` returns a `Promise<Response>` with `Response` being the body of the asset requested.
Known errors to be thrown are:
- MethodNotAllowedError
- NotFoundError
- InternalError
#### ES Modules
```js
import manifestJSON from "__STATIC_CONTENT_MANIFEST";
import {
getAssetFromKV,
MethodNotAllowedError,
NotFoundError,
} from "@cloudflare/kv-asset-handler";
const assetManifest = JSON.parse(manifestJSON);
export default {
async fetch(request, env, ctx) {
if (request.url.includes("/docs")) {
try {
return await getAssetFromKV(
{
request,
waitUntil(promise) {
return ctx.waitUntil(promise);
},
},
{
ASSET_NAMESPACE: env.__STATIC_CONTENT,
ASSET_MANIFEST: assetManifest,
}
);
} catch (e) {
if (e instanceof NotFoundError) {
// ...
} else if (e instanceof MethodNotAllowedError) {
// ...
} else {
return new Response("An unexpected error occurred", { status: 500 });
}
}
} else return fetch(request);
},
};
```
#### Service Worker
```js
import {
getAssetFromKV,
MethodNotAllowedError,
NotFoundError,
} from "@cloudflare/kv-asset-handler";
addEventListener("fetch", (event) => {
event.respondWith(handleEvent(event));
});
async function handleEvent(event) {
if (event.request.url.includes("/docs")) {
try {
return await getAssetFromKV(event);
} catch (e) {
if (e instanceof NotFoundError) {
// ...
} else if (e instanceof MethodNotAllowedError) {
// ...
} else {
return new Response("An unexpected error occurred", { status: 500 });
}
}
} else return fetch(event.request);
}
```
### Optional Arguments
You can customize the behavior of `getAssetFromKV` by passing the following properties as an object into the second argument.
```
getAssetFromKV(event, { mapRequestToAsset: ... })
```
#### `mapRequestToAsset`
mapRequestToAsset(Request) => Request
Maps the incoming request to the value that will be looked up in Cloudflare's KV
By default, mapRequestToAsset is set to the exported function [`mapRequestToAsset`](#maprequesttoasset-1). This works for most static site generators, but you can customize this behavior by passing your own function as `mapRequestToAsset`. The function should take a `Request` object as its only argument, and return a new `Request` object with an updated path to be looked up in the asset manifest/KV.
For SPA mapping pass in the [`serveSinglePageApp`](#servesinglepageapp) function
#### Example
Strip `/docs` from any incoming request before looking up an asset in Cloudflare's KV.
```js
import { getAssetFromKV, mapRequestToAsset } from '@cloudflare/kv-asset-handler'
...
const customKeyModifier = request => {
let url = request.url
//custom key mapping optional
url = url.replace('/docs', '').replace(/^\/+/, '')
return mapRequestToAsset(new Request(url, request))
}
let asset = await getAssetFromKV(event, { mapRequestToAsset: customKeyModifier })
```
#### `cacheControl`
type: object
`cacheControl` allows you to configure options for both the Cloudflare Cache accessed by your Worker, and the browser cache headers sent along with your Workers' responses. The default values are as follows:
```javascript
let cacheControl = {
browserTTL: null, // do not set cache control ttl on responses
edgeTTL: 2 * 60 * 60 * 24, // 2 days
bypassCache: false, // do not bypass Cloudflare's cache
};
```
##### `browserTTL`
type: number | null
nullable: true
Sets the `Cache-Control: max-age` header on the response returned from the Worker. By default set to `null` which will not add the header at all.
##### `edgeTTL`
type: number | null
nullable: true
Sets the `Cache-Control: max-age` header on the response used as the edge cache key. By default set to 2 days (`2 * 60 * 60 * 24`). When null will not cache on the edge at all.
##### `bypassCache`
type: boolean
Determines whether to cache requests on Cloudflare's edge cache. By default set to `false` (recommended for production builds). Useful for development when you need to eliminate the cache's effect on testing.
#### `ASSET_NAMESPACE` (required for ES Modules)
type: KV Namespace Binding
The binding name to the KV Namespace populated with key/value entries of files for the Worker to serve. By default, Workers Sites uses a [binding to a Workers KV Namespace](https://developers.cloudflare.com/workers/reference/storage/api/#namespaces) named `__STATIC_CONTENT`.
It is further assumed that this namespace consists of static assets such as HTML, CSS, JavaScript, or image files, keyed off of a relative path that roughly matches the assumed URL pathname of the incoming request.
In ES Modules format, this argument is required, and can be gotten from `env`.
##### ES Module
```js
return getAssetFromKV(
{
request,
waitUntil(promise) {
return ctx.waitUntil(promise)
},
},
{
ASSET_NAMESPACE: env.__STATIC_CONTENT,
},
)
```
##### Service Worker
```
return getAssetFromKV(event, { ASSET_NAMESPACE: MY_NAMESPACE })
```
#### `ASSET_MANIFEST` (required for ES Modules)
type: text blob (JSON formatted) or object
The mapping of requested file path to the key stored on Cloudflare.
Workers Sites with Wrangler bundles up a text blob that maps request paths to content-hashed keys that are generated by Wrangler as a cache-busting measure. If this option/binding is not present, the function will fallback to using the raw pathname to look up your asset in KV. If, for whatever reason, you have rolled your own implementation of this, you can include your own by passing a stringified JSON object where the keys are expected paths, and the values are the expected keys in your KV namespace.
In ES Modules format, this argument is required, and can be imported.
##### ES Module
```js
import manifestJSON from '__STATIC_CONTENT_MANIFEST'
let manifest = JSON.parse(manifestJSON)
manifest['index.html'] = 'index.special.html'
return getAssetFromKV(
{
request,
waitUntil(promise) {
return ctx.waitUntil(promise)
},
},
{
ASSET_MANIFEST: manifest,
// ...
},
)
```
##### Service Worker
```
let assetManifest = { "index.html": "index.special.html" }
return getAssetFromKV(event, { ASSET_MANIFEST: assetManifest })
```
#### `defaultMimeType` (optional)
type: string
This is the mime type that will be used for files with unrecognized or missing extensions. The default value is `'text/plain'`.
If you are serving a static site and would like to use extensionless HTML files instead of index.html files, set this to `'text/html'`.
#### `defaultDocument` (optional)
type: string
This is the default document that will be concatenated for requests ends in `'/'` or without a valid mime type like `'/about'` or `'/about.me'`. The default value is `'index.html'`.
#### `defaultETag` (optional)
type: `'strong' | 'weak'`
This determines the format of the response [ETag header](https://developer.mozilla.org/docs/Web/HTTP/Headers/ETag). If the resource is in the cache, the ETag will always be weakened before being returned.
The default value is `'strong'`.
# Helper functions
## `mapRequestToAsset`
mapRequestToAsset(Request) => Request
The default function for mapping incoming requests to keys in Cloudflare's KV.
Takes any path that ends in `/` or evaluates to an HTML file and appends `index.html` or `/index.html` for lookup in your Workers KV namespace.
## `serveSinglePageApp`
serveSinglePageApp(Request) => Request
A custom handler for mapping requests to a single root: `index.html`. The most common use case is single-page applications - frameworks with in-app routing - such as React Router, VueJS, etc. It takes zero arguments.
```js
import { getAssetFromKV, serveSinglePageApp } from '@cloudflare/kv-asset-handler'
...
let asset = await getAssetFromKV(event, { mapRequestToAsset: serveSinglePageApp })
```
# Cache revalidation and etags
All responses served from cache (including those with `cf-cache-status: MISS`) include an `etag` response header that identifies the version of the resource. The `etag` value is identical to the path key used in the `ASSET_MANIFEST`. It is updated each time an asset changes and looks like this: `etag: <filename>.<hash of file contents>.<extension>` (ex. `etag: index.54321.html`).
Resources served with an `etag` allow browsers to use the `if-none-match` request header to make conditional requests for that resource in the future. This has two major benefits:
- When a request's `if-none-match` value matches the `etag` of the resource in Cloudflare cache, Cloudflare will send a `304 Not Modified` response without a body, saving bandwidth.
- Changes to a file on the server are immediately reflected in the browser - even when the cache control directive `max-age` is unexpired.
#### Disable the `etag`
To turn `etags` **off**, you must bypass cache:
```js
/* Turn etags off */
let cacheControl = {
bypassCache: true,
};
```
#### Syntax and comparison context
`kv-asset-handler` sets and evaluates etags as [strong validators](https://developer.mozilla.org/en-US/docs/Web/HTTP/Conditional_requests#Strong_validation). To preserve `etag` integrity, the format of the value deviates from the [RFC2616 recommendation to enclose the `etag` with quotation marks](https://tools.ietf.org/html/rfc2616#section-3.11). This is intentional. Cloudflare cache applies the `W/` prefix to all `etags` that use quoted-strings -- a process that converts the `etag` to a "weak validator" when served to a client.

# @cloudflare/unenv-preset
[unenv](https://github.com/unjs/unenv) preset for cloudflare.
unenv provides polyfills to add [Node.js](https://nodejs.org/) compatibility for any JavaScript runtime, including browsers and edge workers.
## Usage
```ts
import { cloudflare } from "@cloudflare/unenv-preset";
import { defineEnv } from "unenv";
const { env } = defineEnv({
presets: [cloudflare],
});
const { alias, inject, external, polyfill } = env;
```
See the unenv [README](https://github.com/unjs/unenv/blob/main/README.md) for more details.

# Source Map Support
[![NPM version](https://img.shields.io/npm/v/@cspotcode/source-map-support.svg?style=flat)](https://npmjs.org/package/@cspotcode/source-map-support)
[![NPM downloads](https://img.shields.io/npm/dm/@cspotcode/source-map-support.svg?style=flat)](https://npmjs.org/package/@cspotcode/source-map-support)
[![Build status](https://img.shields.io/github/workflow/status/cspotcode/node-source-map-support/Continuous%20Integration)](https://github.com/cspotcode/node-source-map-support/actions?query=workflow%3A%22Continuous+Integration%22)
This module provides source map support for stack traces in node via the [V8 stack trace API](https://github.com/v8/v8/wiki/Stack-Trace-API). It uses the [source-map](https://github.com/mozilla/source-map) module to replace the paths and line numbers of source-mapped files with their original paths and line numbers. The output mimics node's stack trace format with the goal of making every compile-to-JS language more of a first-class citizen. Source maps are completely general (not specific to any one language) so you can use source maps with multiple compile-to-JS languages in the same node process.
## Installation and Usage
#### Node support
```
$ npm install @cspotcode/source-map-support
```
Source maps can be generated using libraries such as [source-map-index-generator](https://github.com/twolfson/source-map-index-generator). Once you have a valid source map, place a source mapping comment somewhere in the file (usually done automatically or with an option by your transpiler):
```
//# sourceMappingURL=path/to/source.map
```
If multiple sourceMappingURL comments exist in one file, the last sourceMappingURL comment will be
respected (e.g. if a file mentions the comment in code, or went through multiple transpilers).
The path should either be absolute or relative to the compiled file.
From here you have two options.
##### CLI Usage
```bash
node -r @cspotcode/source-map-support/register compiled.js
# Or to enable hookRequire
node -r @cspotcode/source-map-support/register-hook-require compiled.js
```
##### Programmatic Usage
Put the following line at the top of the compiled file.
```js
require('@cspotcode/source-map-support').install();
```
It is also possible to install the source map support directly by
requiring the `register` module which can be handy with ES6:
```js
import '@cspotcode/source-map-support/register'
// Instead of:
import sourceMapSupport from '@cspotcode/source-map-support'
sourceMapSupport.install()
```
Note: if you're using babel-register, it includes source-map-support already.
It is also very useful with Mocha:
```
$ mocha --require @cspotcode/source-map-support/register tests/
```
#### Browser support
This library also works in Chrome. While the DevTools console already supports source maps, the V8 engine doesn't and `Error.prototype.stack` will be incorrect without this library. Everything will just work if you deploy your source files using [browserify](http://browserify.org/). Just make sure to pass the `--debug` flag to the browserify command so your source maps are included in the bundled code.
This library also works if you use another build process or just include the source files directly. In this case, include the file `browser-source-map-support.js` in your page and call `sourceMapSupport.install()`. It contains the whole library already bundled for the browser using browserify.
```html
<script src="browser-source-map-support.js"></script>
<script>sourceMapSupport.install();</script>
```
This library also works if you use AMD (Asynchronous Module Definition), which is used in tools like [RequireJS](http://requirejs.org/). Just list `browser-source-map-support` as a dependency:
```html
<script>
define(['browser-source-map-support'], function(sourceMapSupport) {
sourceMapSupport.install();
});
</script>
```
## Options
This module installs two things: a change to the `stack` property on `Error` objects and a handler for uncaught exceptions that mimics node's default exception handler (the handler can be seen in the demos below). You may want to disable the handler if you have your own uncaught exception handler. This can be done by passing an argument to the installer:
```js
require('@cspotcode/source-map-support').install({
handleUncaughtExceptions: false
});
```
This module loads source maps from the filesystem by default. You can provide alternate loading behavior through a callback as shown below. For example, [Meteor](https://github.com/meteor) keeps all source maps cached in memory to avoid disk access.
```js
require('@cspotcode/source-map-support').install({
retrieveSourceMap: function(source) {
if (source === 'compiled.js') {
return {
url: 'original.js',
map: fs.readFileSync('compiled.js.map', 'utf8')
};
}
return null;
}
});
```
The module will by default assume a browser environment if XMLHttpRequest and window are defined. If either of these do not exist it will instead assume a node environment.
In some rare cases, e.g. when running a browser emulation and where both variables are also set, you can explictly specify the environment to be either 'browser' or 'node'.
```js
require('@cspotcode/source-map-support').install({
environment: 'node'
});
```
To support files with inline source maps, the `hookRequire` options can be specified, which will monitor all source files for inline source maps.
```js
require('@cspotcode/source-map-support').install({
hookRequire: true
});
```
This monkey patches the `require` module loading chain, so is not enabled by default and is not recommended for any sort of production usage.
## Demos
#### Basic Demo
original.js:
```js
throw new Error('test'); // This is the original code
```
compiled.js:
```js
require('@cspotcode/source-map-support').install();
throw new Error('test'); // This is the compiled code
// The next line defines the sourceMapping.
//# sourceMappingURL=compiled.js.map
```
compiled.js.map:
```json
{
"version": 3,
"file": "compiled.js",
"sources": ["original.js"],
"names": [],
"mappings": ";;AAAA,MAAM,IAAI"
}
```
Run compiled.js using node (notice how the stack trace uses original.js instead of compiled.js):
```
$ node compiled.js
original.js:1
throw new Error('test'); // This is the original code
^
Error: test
at Object.<anonymous> (original.js:1:7)
at Module._compile (module.js:456:26)
at Object.Module._extensions..js (module.js:474:10)
at Module.load (module.js:356:32)
at Function.Module._load (module.js:312:12)
at Function.Module.runMain (module.js:497:10)
at startup (node.js:119:16)
at node.js:901:3
```
#### TypeScript Demo
demo.ts:
```typescript
declare function require(name: string);
require('@cspotcode/source-map-support').install();
class Foo {
constructor() { this.bar(); }
bar() { throw new Error('this is a demo'); }
}
new Foo();
```
Compile and run the file using the TypeScript compiler from the terminal:
```
$ npm install source-map-support typescript
$ node_modules/typescript/bin/tsc -sourcemap demo.ts
$ node demo.js
demo.ts:5
bar() { throw new Error('this is a demo'); }
^
Error: this is a demo
at Foo.bar (demo.ts:5:17)
at new Foo (demo.ts:4:24)
at Object.<anonymous> (demo.ts:7:1)
at Module._compile (module.js:456:26)
at Object.Module._extensions..js (module.js:474:10)
at Module.load (module.js:356:32)

at Function.Module.runMain (module.js:497:10)
at startup (node.js:119:16)
at node.js:901:3
```
There is also the option to use `-r source-map-support/register` with typescript, without the need add the `require('@cspotcode/source-map-support').install()` in the code base:
```
$ npm install source-map-support typescript
$ node_modules/typescript/bin/tsc -sourcemap demo.ts
$ node -r source-map-support/register demo.js
demo.ts:5
bar() { throw new Error('this is a demo'); }
^
Error: this is a demo
at Foo.bar (demo.ts:5:17)
at new Foo (demo.ts:4:24)
at Object.<anonymous> (demo.ts:7:1)
at Module._compile (module.js:456:26)
at Object.Module._extensions..js (module.js:474:10)
at Module.load (module.js:356:32)
at Function.Module._load (module.js:312:12)
at Function.Module.runMain (module.js:497:10)
at startup (node.js:119:16)
at node.js:901:3
```
#### CoffeeScript Demo
demo.coffee:
```coffee
require('@cspotcode/source-map-support').install()
foo = ->
bar = -> throw new Error 'this is a demo'
bar()
foo()
```
Compile and run the file using the CoffeeScript compiler from the terminal:
```sh
$ npm install @cspotcode/source-map-support coffeescript
$ node_modules/.bin/coffee --map --compile demo.coffee
$ node demo.js
demo.coffee:3
bar = -> throw new Error 'this is a demo'
^
Error: this is a demo
at bar (demo.coffee:3:22)
at foo (demo.coffee:4:3)
at Object.<anonymous> (demo.coffee:5:1)
at Object.<anonymous> (demo.coffee:1:1)
at Module._compile (module.js:456:26)
at Object.Module._extensions..js (module.js:474:10)
at Module.load (module.js:356:32)
at Function.Module._load (module.js:312:12)
at Function.Module.runMain (module.js:497:10)
at startup (node.js:119:16)
```
## Tests
This repo contains both automated tests for node and manual tests for the browser. The automated tests can be run using mocha (type `mocha` in the root directory). To run the manual tests:
* Build the tests using `build.js`
* Launch the HTTP server (`npm run serve-tests`) and visit
* http://127.0.0.1:1336/amd-test
* http://127.0.0.1:1336/browser-test
* http://127.0.0.1:1336/browserify-test - **Currently not working** due to a bug with browserify (see [pull request #66](https://github.com/evanw/node-source-map-support/pull/66) for details).
* For `header-test`, run `server.js` inside that directory and visit http://127.0.0.1:1337/

Description
===========
A Node.js module for parsing incoming HTML form data.
This is an officially supported fork by [fastify](https://github.com/fastify/) organization of the amazing library [originally created](https://github.com/mscdex/busboy) by Brian White,
aimed at addressing long-standing issues with it.
Benchmark (Mean time for 500 Kb payload, 2000 cycles, 1000 cycle warmup):
| Library | Version | Mean time in nanoseconds (less is better) |
|-----------------------|---------|-------------------------------------------|
| busboy | 0.3.1 | `340114` |
| @fastify/busboy | 1.0.0 | `270984` |
[Changelog](https://github.com/fastify/busboy/blob/master/CHANGELOG.md) since busboy 0.31.
Requirements
============
* [Node.js](http://nodejs.org/) 10+
Install
=======
npm i @fastify/busboy
Examples
========
* Parsing (multipart) with default options:
```javascript
const http = require('node:http');
const { inspect } = require('node:util');
const Busboy = require('busboy');
http.createServer((req, res) => {
if (req.method === 'POST') {
const busboy = new Busboy({ headers: req.headers });
busboy.on('file', (fieldname, file, filename, encoding, mimetype) => {
console.log(`File [${fieldname}]: filename: ${filename}, encoding: ${encoding}, mimetype: ${mimetype}`);
file.on('data', data => {
console.log(`File [${fieldname}] got ${data.length} bytes`);
});
file.on('end', () => {
console.log(`File [${fieldname}] Finished`);
});
});
busboy.on('field', (fieldname, val, fieldnameTruncated, valTruncated, encoding, mimetype) => {
console.log(`Field [${fieldname}]: value: ${inspect(val)}`);
});
busboy.on('finish', () => {

<input type="file" name="filefield"><br>
<input type="submit">
</form>
</body></html>`);
}
}).listen(8000, () => {

});
// Example output, using http://nodejs.org/images/ryan-speaker.jpg as the file:
//
// Listening for requests
// File [filefield]: filename: ryan-speaker.jpg, encoding: binary
// File [filefield] got 11971 bytes
// Field [textfield]: value: 'testing! :-)'
// File [filefield] Finished
// Done parsing form!
```
* Save all incoming files to disk:
```javascript
const http = require('node:http');
const path = require('node:path');
const os = require('node:os');
const fs = require('node:fs');
const Busboy = require('busboy');
http.createServer(function(req, res) {

var saveTo = path.join(os.tmpdir(), path.basename(fieldname));
file.pipe(fs.createWriteStream(saveTo));
});

* **file**(< _string_ >fieldname, < _ReadableStream_ >stream, < _string_ >filename, < _string_ >transferEncoding, < _string_ >mimeType) - Emitted for each new file form field found. `transferEncoding` contains the 'Content-Transfer-Encoding' value for the file stream. `mimeType` contains the 'Content-Type' value for the file stream.
* Note: if you listen for this event, you should always handle the `stream` no matter if you care about the file contents or not (e.g. you can simply just do `stream.resume();` if you want to discard the contents), otherwise the 'finish' event will never fire on the Busboy instance. However, if you don't care about **any** incoming files, you can simply not listen for the 'file' event at all and any/all files will be automatically and safely discarded (these discarded files do still count towards `files` and `parts` limits).
* If a configured file size limit was reached, `stream` will both have a boolean property `truncated` (best checked at the end of the stream) and emit a 'limit' event to notify you when this happens.
* The property `bytesRead` informs about the number of bytes that have been read so far.
* **field**(< _string_ >fieldname, < _string_ >value, < _boolean_ >fieldnameTruncated, < _boolean_ >valueTruncated, < _string_ >transferEncoding, < _string_ >mimeType) - Emitted for each new non-file field found.
* **partsLimit**() - Emitted when specified `parts` limit has been reached. No more 'file' or 'field' events will be emitted.
* **filesLimit**() - Emitted when specified `files` limit has been reached. No more 'file' events will be emitted.
* **fieldsLimit**() - Emitted when specified `fields` limit has been reached. No more 'field' events will be emitted.
Busboy methods
--------------
* **(constructor)**(< _object_ >config) - Creates and returns a new Busboy instance.
* The constructor takes the following valid `config` settings:
* **headers** - _object_ - These are the HTTP headers of the incoming request, which are used by individual parsers.
* **autoDestroy** - _boolean_ - Whether this stream should automatically call .destroy() on itself after ending. (Default: false).
* **highWaterMark** - _integer_ - highWaterMark to use for this Busboy instance (Default: WritableStream default).
* **fileHwm** - _integer_ - highWaterMark to use for file streams (Default: ReadableStream default).
* **defCharset** - _string_ - Default character set to use when one isn't defined (Default: 'utf8').
* **preservePath** - _boolean_ - If paths in the multipart 'filename' field shall be preserved. (Default: false).
* **isPartAFile** - __function__ - Use this function to override the default file detection functionality. It has following parameters:
* fieldName - __string__ The name of the field.
* contentType - __string__ The content-type of the part, e.g. `text/plain`, `image/jpeg`, `application/octet-stream`
* fileName - __string__ The name of a file supplied by the part.
(Default: `(fieldName, contentType, fileName) => (contentType === 'application/octet-stream' || fileName !== undefined)`)
* **limits** - _object_ - Various limits on incoming data. Valid properties are:
* **fieldNameSize** - _integer_ - Max field name size (in bytes) (Default: 100 bytes).
* **fieldSize** - _integer_ - Max field value size (in bytes) (Default: 1 MiB, which is 1024 x 1024 bytes).
* **fields** - _integer_ - Max number of non-file fields (Default: Infinity).
* **fileSize** - _integer_ - For multipart forms, the max file size (in bytes) (Default: Infinity).
* **files** - _integer_ - For multipart forms, the max number of file fields (Default: Infinity).
* **parts** - _integer_ - For multipart forms, the max number of parts (fields + files) (Default: Infinity).
* **headerPairs** - _integer_ - For multipart forms, the max number of header key=>value pairs to parse **Default:** 2000
* **headerSize** - _integer_ - For multipart forms, the max size of a multipart header **Default:** 81920.
* The constructor can throw errors:
* **Busboy expected an options-Object.** - Busboy expected an Object as first parameters.
* **Busboy expected an options-Object with headers-attribute.** - The first parameter is lacking of a headers-attribute.
* **Limit $limit is not a valid number** - Busboy expected the desired limit to be of type number. Busboy throws this Error to prevent a potential security issue by falling silently back to the Busboy-defaults. Potential source for this Error can be the direct use of environment variables without transforming them to the type number.
* **Unsupported Content-Type.** - The `Content-Type` isn't one Busboy can parse.
* **Missing Content-Type-header.** - The provided headers don't include `Content-Type` at all.

"Work" shall mean the work of authorship, whether in Source or Object form, made
available under the License, as indicated by a copyright notice that is included
in or attached to the work (an example is provided in the Appendix below).
"Derivative Works" shall mean any work, whether in Source or Object form, that
is based on (or derived from) the Work and for which the editorial revisions,
annotations, elaborations, or other modifications represent, as a whole, an

shall not include works that remain separable from, or merely link (or bind by
name) to the interfaces of, the Work and Derivative Works thereof.
"Contribution" shall mean any work of authorship, including the original version
of the Work and any modifications or additions to that Work or Derivative Works
thereof, that is intentionally submitted to Licensor for inclusion in the Work
by the copyright owner or by an individual or Legal Entity authorized to submit
on behalf of the copyright owner. For the purposes of this definition,
"submitted" means any form of electronic, verbal, or written communication sent

2. Grant of Copyright License.
Subject to the terms and conditions of this License, each Contributor hereby
grants to You a perpetual, worldwide, non-exclusive, no-charge, royalty-free,
irrevocable copyright license to reproduce, prepare Derivative Works of,
publicly display, publicly perform, sublicense, and distribute the Work and such
Derivative Works in Source or Object form.
3. Grant of Patent License.
Subject to the terms and conditions of this License, each Contributor hereby
grants to You a perpetual, worldwide, non-exclusive, no-charge, royalty-free,
irrevocable (except as stated in this section) patent license to make, have
made, use, offer to sell, sell, import, and otherwise transfer the Work, where
such license applies only to those patent claims licensable by such Contributor
that are necessarily infringed by their Contribution(s) alone or by combination
of their Contribution(s) with the Work to which such Contribution(s) was
submitted. If You institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work or a
Contribution incorporated within the Work constitutes direct or contributory
patent infringement, then any patent licenses granted to You under this License
for that Work shall terminate as of the date such litigation is filed.
4. Redistribution.
You may reproduce and distribute copies of the Work or Derivative Works thereof
in any medium, with or without modifications, and in Source or Object form,
provided that You meet the following conditions:
You must give any other recipients of the Work or Derivative Works a copy of
this License; and
You must cause any modified files to carry prominent notices stating that You
changed the files; and
You must retain, in the Source form of any Derivative Works that You distribute,
all copyright, patent, trademark, and attribution notices from the Source form
of the Work, excluding those notices that do not pertain to any part of the
Derivative Works; and
If the Work includes a "NOTICE" text file as part of its distribution, then any
Derivative Works that You distribute must include a readable copy of the
attribution notices contained within such NOTICE file, excluding those notices
that do not pertain to any part of the Derivative Works, in at least one of the
following places: within a NOTICE text file distributed as part of the
Derivative Works; within the Source form or documentation, if provided along
with the Derivative Works; or, within a display generated by the Derivative
Works, if and wherever such third-party notices normally appear. The contents of
the NOTICE file are for informational purposes only and do not modify the
License. You may add Your own attribution notices within Derivative Works that
You distribute, alongside or as an addendum to the NOTICE text from the Work,
provided that such additional attribution notices cannot be construed as
modifying the License.
You may add Your own copyright statement to Your modifications and may provide
additional or different license terms and conditions for use, reproduction, or
distribution of Your modifications, or for any such Derivative Works as a whole,
provided Your use, reproduction, and distribution of the Work otherwise complies
with the conditions stated in this License.
5. Submission of Contributions.
Unless You explicitly state otherwise, any Contribution intentionally submitted
for inclusion in the Work by You to the Licensor shall be under the terms and
conditions of this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify the terms of
any separate license agreement you may have executed with Licensor regarding
such Contributions.
6. Trademarks.
This License does not grant permission to use the trade names, trademarks,
service marks, or product names of the Licensor, except as required for
reasonable and customary use in describing the origin of the Work and
reproducing the content of the NOTICE file.
7. Disclaimer of Warranty.
Unless required by applicable law or agreed to in writing, Licensor provides the
Work (and each Contributor provides its Contributions) on an "AS IS" BASIS,
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied,
including, without limitation, any warranties or conditions of TITLE,
NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE. You are
solely responsible for determining the appropriateness of using or
redistributing the Work and assume any risks associated with Your exercise of
permissions under this License.
8. Limitation of Liability.
In no event and under no legal theory, whether in tort (including negligence),
contract, or otherwise, unless required by applicable law (such as deliberate
and grossly negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special, incidental,
or consequential damages of any character arising as a result of this License or
out of the use or inability to use the Work (including but not limited to
damages for loss of goodwill, work stoppage, computer failure or malfunction, or
any and all other commercial damages or losses), even if such Contributor has
been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability.
While redistributing the Work or Derivative Works thereof, You may choose to
offer, and charge a fee for, acceptance of support, warranty, indemnity, or
other liability obligations and/or rights consistent with this License. However,
in accepting such obligations, You may act only on Your own behalf and on Your
sole responsibility, not on behalf of any other Contributor, and only if You
agree to indemnify, defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason of your
accepting any such warranty or additional liability.

# @jridgewell/resolve-uri
> Resolve a URI relative to an optional base URI
Resolve any combination of absolute URIs, protocol-realtive URIs, absolute paths, or relative paths.
## Installation
```sh
npm install @jridgewell/resolve-uri
```
## Usage
```typescript
function resolve(input: string, base?: string): string;
```
```js
import resolve from '@jridgewell/resolve-uri';
resolve('foo', 'https://example.com'); // => 'https://example.com/foo'
```
| Input | Base | Resolution | Explanation |
|-----------------------|-------------------------|--------------------------------|--------------------------------------------------------------|
| `https://example.com` | _any_ | `https://example.com/` | Input is normalized only |
| `//example.com` | `https://base.com/` | `https://example.com/` | Input inherits the base's protocol |

# @jridgewell/sourcemap-codec
Encode/decode the `mappings` property of a [sourcemap](https://docs.google.com/document/d/1U1RGAehQwRypUTovF1KRlpiOFze0b-_2gc6fAH0KY0k/edit).
## Why?
Sourcemaps are difficult to generate and manipulate, because the `mappings` property – the part that actually links the generated code back to the original source – is encoded using an obscure method called [Variable-length quantity](https://en.wikipedia.org/wiki/Variable-length_quantity). On top of that, each segment in the mapping contains offsets rather than absolute indices, which means that you can't look at a segment in isolation – you have to understand the whole sourcemap.
This package makes the process slightly easier.
## Installation
```bash
npm install @jridgewell/sourcemap-codec
```
## Usage
```js
import { encode, decode } from '@jridgewell/sourcemap-codec';
var decoded = decode( ';EAEEA,EAAE,EAAC,CAAE;ECQY,UACC' );
assert.deepEqual( decoded, [
// the first line (of the generated code) has no mappings,
// as shown by the starting semi-colon (which separates lines)
[],
// the second line contains four (comma-separated) segments
[
// segments are encoded as you'd expect:
// [ generatedCodeColumn, sourceIndex, sourceCodeLine, sourceCodeColumn, nameIndex ]
// i.e. the first segment begins at column 2, and maps back to the second column
// of the second line (both zero-based) of the 0th source, and uses the 0th
// name in the `map.names` array
[ 2, 0, 2, 2, 0 ],
// the remaining segments are 4-length rather than 5-length,
// because they don't map a name
[ 4, 0, 2, 4 ],
[ 6, 0, 2, 5 ],
[ 7, 0, 2, 7 ]
],
// the final line contains two segments
[
[ 2, 1, 10, 19 ],
[ 12, 1, 11, 20 ]
]
]);
var encoded = encode( decoded );
assert.equal( encoded, ';EAEEA,EAAE,EAAC,CAAE;ECQY,UACC' );
```
