# readable-web-to-node-stream
Converts a [Web-API readable stream](https://developer.mozilla.org/en-US/docs/Web/API/ReadableStreamDefaultReader) into a [Node.js readable stream](https://nodejs.org/api/stream.html#stream_readable_streams).
## Installation
Install via [npm](http://npmjs.org/):
```bash
npm install readable-web-to-node-stream
```
or or [yarn](https://yarnpkg.com/):
```bash
yarn add readable-web-to-node-stream
```
## Compatibility
Source is written in TypeScript and compiled to ECMAScript 2017 (ES8).
Unit tests are performed on the following browsers:
* Google Chrome 74.0
* Firefox 68.0
* Safari 12.0
* Opera 60.0
## Example
Import readable-web-stream-to-node in JavaScript:
```js
const {ReadableWebToNodeStream} = require('readable-web-to-node-stream');
async function download(url) {
const response = await fetch(url);
const readableWebStream = response.body;
const nodeStream = new ReadableWebToNodeStream(readableWebStream);
}
```
## API
**constructor(stream: ReadableStream): Promise<void>**
`stream: ReadableStream`: the [Web-API readable stream](https://developer.mozilla.org/en-US/docs/Web/API/ReadableStreamDefaultReader).
**close(): Promise<void>**
Will cancel close the Readable-node stream, and will release Web-API-readable-stream.
**waitForReadToComplete(): Promise<void>**
If there is no unresolved read call to Web-API Readable​Stream immediately returns, otherwise it will wait until the read is resolved.

#### The buffer module from [node.js](https://nodejs.org/), for the browser.

[saucelabs-image]: https://saucelabs.com/browser-matrix/buffer.svg
[saucelabs-url]: https://saucelabs.com/u/buffer
With [browserify](http://browserify.org), simply `require('buffer')` or use the `Buffer` global and you will get this module.
The goal is to provide an API that is 100% identical to
[node's Buffer API](https://nodejs.org/api/buffer.html). Read the
[official docs](https://nodejs.org/api/buffer.html) for the full list of properties,
instance methods, and class methods that are supported.
## features
- Manipulate binary data like a boss, in all browsers!
- Super fast. Backed by Typed Arrays (`Uint8Array`/`ArrayBuffer`, not `Object`)
- Extremely small bundle size (**6.75KB minified + gzipped**, 51.9KB with comments)
- Excellent browser support (Chrome, Firefox, Edge, Safari 11+, iOS 11+, Android, etc.)
- Preserves Node API exactly, with one minor difference (see below)
- Square-bracket `buf[4]` notation works!
- Does not modify any browser prototypes or put anything on `window`
- Comprehensive test suite (including all buffer tests from node.js core)
## install
To use this module directly (without browserify), install it:
```bash
npm install buffer
```
This module was previously called **native-buffer-browserify**, but please use **buffer**
from now on.
If you do not use a bundler, you can use the [standalone script](https://bundle.run/buffer).
## usage
The module's API is identical to node's `Buffer` API. Read the
[official docs](https://nodejs.org/api/buffer.html) for the full list of properties,
instance methods, and class methods that are supported.
As mentioned above, `require('buffer')` or use the `Buffer` global with
[browserify](http://browserify.org) and this module will automatically be included
in your bundle. Almost any npm module will work in the browser, even if it assumes that
the node `Buffer` API will be available.
To depend on this module explicitly (without browserify), require it like this:
```js
var Buffer = require('buffer/').Buffer // note: the trailing slash is important!
```
To require this module explicitly, use `require('buffer/')` which tells the node.js module
lookup algorithm (also used by browserify) to use the **npm module** named `buffer`
instead of the **node.js core** module named `buffer`!
## how does it work?
The Buffer constructor returns instances of `Uint8Array` that have their prototype
changed to `Buffer.prototype`. Furthermore, `Buffer` is a subclass of `Uint8Array`,
so the returned instances will have all the node `Buffer` methods and the
`Uint8Array` methods. Square bracket notation works as expected -- it returns a
single octet.
The `Uint8Array` prototype remains unmodified.
## tracking the latest node api
This module tracks the Buffer API in the latest (unstable) version of node.js. The Buffer
API is considered **stable** in the
[node stability index](https://nodejs.org/docs/latest/api/documentation.html#documentation_stability_index),
so it is unlikely that there will ever be breaking changes.
Nonetheless, when/if the Buffer API changes in node, this module's API will change
accordingly.

## conversion packages
### convert typed array to buffer
Use [`typedarray-to-buffer`](https://www.npmjs.com/package/typedarray-to-buffer) to convert any kind of typed array to a `Buffer`. Does not perform a copy, so it's super fast.
### convert buffer to typed array
`Buffer` is a subclass of `Uint8Array` (which is a typed array). So there is no need to explicitly convert to typed array. Just use the buffer as a `Uint8Array`.
### convert blob to buffer
Use [`blob-to-buffer`](https://www.npmjs.com/package/blob-to-buffer) to convert a `Blob` to a `Buffer`.
### convert buffer to blob
To convert a `Buffer` to a `Blob`, use the `Blob` constructor:
```js
var blob = new Blob([ buffer ])
```
Optionally, specify a mimetype:
```js
var blob = new Blob([ buffer ], { type: 'text/html' })
```
### convert arraybuffer to buffer
To convert an `ArrayBuffer` to a `Buffer`, use the `Buffer.from` function. Does not perform a copy, so it's super fast.
```js
var buffer = Buffer.from(arrayBuffer)
```
### convert buffer to arraybuffer
To convert a `Buffer` to an `ArrayBuffer`, use the `.buffer` property (which is present on all `Uint8Array` objects):
```js
var arrayBuffer = buffer.buffer.slice(
buffer.byteOffset, buffer.byteOffset + buffer.byteLength
)
```
Alternatively, use the [`to-arraybuffer`](https://www.npmjs.com/package/to-arraybuffer) module.
## performance
See perf tests in `/perf`.
`BrowserBuffer` is the browser `buffer` module (this repo). `Uint8Array` is included as a
sanity check (since `BrowserBuffer` uses `Uint8Array` under the hood, `Uint8Array` will
always be at least a bit faster). Finally, `NodeBuffer` is the node.js buffer module,
which is included to compare against.
NOTE: Performance has improved since these benchmarks were taken. PR welcome to update the README.

## Testing the project
First, install the project:
npm install
Then, to run tests in Node.js, run:
npm run test-node
To test locally in a browser, you can run:
npm run test-browser-es5-local # For ES5 browsers that don't support ES6
npm run test-browser-es6-local # For ES6 compliant browsers
This will print out a URL that you can then open in a browser to run the tests, using [airtap](https://www.npmjs.com/package/airtap).
To run automated browser tests using Saucelabs, ensure that your `SAUCE_USERNAME` and `SAUCE_ACCESS_KEY` environment variables are set, then run:
npm test
This is what's run in Travis, to check against various browsers. The list of browsers is kept in the `bin/airtap-es5.yml` and `bin/airtap-es6.yml` files.

### Streams Working Group
The Node.js Streams is jointly governed by a Working Group
(WG)
that is responsible for high-level guidance of the project.
The WG has final authority over this project including:
* Technical direction
* Project governance and process (including this policy)
* Contribution policy
* GitHub repository hosting
* Conduct guidelines
* Maintaining the list of additional Collaborators
For the current list of WG members, see the project
[README.md](./README.md#current-project-team-members).
### Collaborators
The readable-stream GitHub repository is
maintained by the WG and additional Collaborators who are added by the
WG on an ongoing basis.
Individuals making significant and valuable contributions are made
Collaborators and given commit-access to the project. These
individuals are identified by the WG and their addition as
Collaborators is discussed during the WG meeting.
_Note:_ If you make a significant contribution and are not considered
for commit-access log an issue or contact a WG member directly and it
will be brought up in the next WG meeting.
Modifications of the contents of the readable-stream repository are
made on
a collaborative basis. Anybody with a GitHub account may propose a
modification via pull request and it will be considered by the project
Collaborators. All pull requests must be reviewed and accepted by a
Collaborator with sufficient expertise who is able to take full
responsibility for the change. In the case of pull requests proposed
by an existing Collaborator, an additional Collaborator is required
for sign-off. Consensus should be sought if additional Collaborators
participate and there is disagreement around a particular
modification. See _Consensus Seeking Process_ below for further detail
on the consensus model used for governance.
Collaborators may opt to elevate significant or controversial
modifications, or modifications that have not found consensus to the
WG for discussion by assigning the ***WG-agenda*** tag to a pull
request or issue. The WG should serve as the final arbiter where
required.
For the current list of Collaborators, see the project
[README.md](./README.md#members).
### WG Membership
WG seats are not time-limited. There is no fixed size of the WG.
However, the expected target is between 6 and 12, to ensure adequate
coverage of important areas of expertise, balanced with the ability to
make decisions efficiently.
There is no specific set of requirements or qualifications for WG
membership beyond these rules.
The WG may add additional members to the WG by unanimous consensus.
A WG member may be removed from the WG by voluntary resignation, or by
unanimous consensus of all other WG members.
Changes to WG membership should be posted in the agenda, and may be
suggested as any other agenda item (see "WG Meetings" below).
If an addition or removal is proposed during a meeting, and the full
WG is not in attendance to participate, then the addition or removal
is added to the agenda for the subsequent meeting. This is to ensure
that all members are given the opportunity to participate in all
membership decisions. If a WG member is unable to attend a meeting
where a planned membership decision is being made, then their consent
is assumed.
No more than 1/3 of the WG members may be affiliated with the same
employer. If removal or resignation of a WG member, or a change of
employment by a WG member, creates a situation where more than 1/3 of
the WG membership shares an employer, then the situation must be
immediately remedied by the resignation or removal of one or more WG
members affiliated with the over-represented employer(s).
### WG Meetings
The WG meets occasionally on a Google Hangout On Air. A designated moderator
approved by the WG runs the meeting. Each meeting should be
published to YouTube.
Items are added to the WG agenda that are considered contentious or
are modifications of governance, contribution policy, WG membership,
or release process.
The intention of the agenda is not to approve or review all patches;
that should happen continuously on GitHub and be handled by the larger
group of Collaborators.
Any community member or contributor can ask that something be added to
the next meeting's agenda by logging a GitHub Issue. Any Collaborator,
WG member or the moderator can add the item to the agenda by adding
the ***WG-agenda*** tag to the issue.
Prior to each WG meeting the moderator will share the Agenda with
members of the WG. WG members can add any items they like to the
agenda at the beginning of each meeting. The moderator and the WG
cannot veto or remove items.
The WG may invite persons or representatives from certain projects to
participate in a non-voting capacity.
The moderator is responsible for summarizing the discussion of each
agenda item and sends it as a pull request after the meeting.
### Consensus Seeking Process
The WG follows a
[Consensus
Seeking](http://en.wikipedia.org/wiki/Consensus-seeking_decision-making)
decision-making model.
When an agenda item has appeared to reach a consensus the moderator
will ask "Does anyone object?" as a final call for dissent from the
consensus.
If an agenda item cannot reach a consensus a WG member can call for
either a closing vote or a vote to table the issue to the next
meeting. The call for a vote must be seconded by a majority of the WG
or else the discussion will continue. Simple majority wins.
Note that changes to WG membership require a majority consensus. See
"WG Membership" above.

Note that `require('stream')` will return `Stream`, while
`require('readable-stream')` will return `Readable`. We discourage using
whatever is exported directly, but rather use one of the properties as
shown in the example above.
## Usage In Browsers
You will need a bundler like [`browserify`](https://github.com/browserify/browserify#readme), [`webpack`](https://webpack.js.org/), [`parcel`](https://github.com/parcel-bundler/parcel#readme) or similar. Polyfills are no longer required since version 4.2.0.

'use strict'
// a transform stream is a readable/writable stream where you do
// something with the data. Sometimes it's called a "filter",
// but that's not a great name for it, since that implies a thing where
// some bits pass through, and others are simply ignored. (That would
// be a valid example of a transform, of course.)
//
// While the output is causally related to the input, it's not a
// necessarily symmetric or synchronous transformation. For example,
// a zlib stream might take multiple plain-text writes(), and then
// emit a single compressed chunk some time in the future.
//
// Here's how this works:
//
// The Transform stream has all the aspects of the readable and writable
// stream classes. When you write(chunk), that calls _write(chunk,cb)
// internally, and returns false if there's a lot of pending writes
// buffered up. When you call read(), that calls _read(n) until
// there's enough pending readable data buffered up.
//
// In a transform stream, the written data is placed in a buffer. When
// _read(n) is called, it transforms the queued up data, calling the
// buffered _write cb's as it consumes chunks. If consuming a single
// written chunk would result in multiple output chunks, then the first
// outputted bit calls the readcb, and subsequent chunks just go into
// the read buffer, and will cause it to emit 'readable' if necessary.
//
// This way, back-pressure is actually determined by the reading side,
// since _read has to be called to start processing a new chunk. However,
// a pathological inflate type of transform can cause excessive buffering
// here. For example, imagine a stream where every byte of input is
// interpreted as an integer from 0-255, and then results in that many
// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in
// 1kb of data being output. In this case, you could write a very small
// amount of input, and end up with a very large amount of output. In
// such a pathological inflating mechanism, there'd be no way to tell
// the system to stop doing the transform. A single 4MB write could
// cause the system to run out of memory.
//
// However, even in such a pathological case, only a single written chunk
// would be consumed, and then the rest would wait (un-transformed) until
// the results of the previous transformed chunk were consumed.

// a transform stream is a readable/writable stream where you do
// something with the data. Sometimes it's called a "filter",
// but that's not a great name for it, since that implies a thing where
// some bits pass through, and others are simply ignored. (That would
// be a valid example of a transform, of course.)
//
// While the output is causally related to the input, it's not a
// necessarily symmetric or synchronous transformation. For example,
// a zlib stream might take multiple plain-text writes(), and then
// emit a single compressed chunk some time in the future.
//
// Here's how this works:
//
// The Transform stream has all the aspects of the readable and writable
// stream classes. When you write(chunk), that calls _write(chunk,cb)
// internally, and returns false if there's a lot of pending writes
// buffered up. When you call read(), that calls _read(n) until
// there's enough pending readable data buffered up.
//
// In a transform stream, the written data is placed in a buffer. When
// _read(n) is called, it transforms the queued up data, calling the
// buffered _write cb's as it consumes chunks. If consuming a single
// written chunk would result in multiple output chunks, then the first
// outputted bit calls the readcb, and subsequent chunks just go into
// the read buffer, and will cause it to emit 'readable' if necessary.
//
// This way, back-pressure is actually determined by the reading side,
// since _read has to be called to start processing a new chunk. However,
// a pathological inflate type of transform can cause excessive buffering
// here. For example, imagine a stream where every byte of input is
// interpreted as an integer from 0-255, and then results in that many
// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in
// 1kb of data being output. In this case, you could write a very small
// amount of input, and end up with a very large amount of output. In
// such a pathological inflating mechanism, there'd be no way to tell
// the system to stop doing the transform. A single 4MB write could
// cause the system to run out of memory.
//
// However, even in such a pathological case, only a single written chunk
// would be consumed, and then the rest would wait (un-transformed) until
// the results of the previous transformed chunk were consumed.

# string_decoder
***Node-core v8.9.4 string_decoder for userland***
[![NPM](https://nodei.co/npm/string_decoder.png?downloads=true&downloadRank=true)](https://nodei.co/npm/string_decoder/)
[![NPM](https://nodei.co/npm-dl/string_decoder.png?&months=6&height=3)](https://nodei.co/npm/string_decoder/)
```bash
npm install --save string_decoder
```
***Node-core string_decoder for userland***
This package is a mirror of the string_decoder implementation in Node-core.
Full documentation may be found on the [Node.js website](https://nodejs.org/dist/v8.9.4/docs/api/).
As of version 1.0.0 **string_decoder** uses semantic versioning.
## Previous versions
Previous version numbers match the versions found in Node core, e.g. 0.10.24 matches Node 0.10.24, likewise 0.11.10 matches Node 0.11.10.
## Update
The *build/* directory contains a build script that will scrape the source from the [nodejs/node](https://github.com/nodejs/node) repo given a specific Node version.
## Streams Working Group
`string_decoder` is maintained by the Streams Working Group, which
oversees the development and maintenance of the Streams API within
Node.js. The responsibilities of the Streams Working Group include:
* Addressing stream issues on the Node.js issue tracker.
* Authoring and editing stream documentation within the Node.js project.
* Reviewing changes to stream subclasses within the Node.js project.
* Redirecting changes to streams from the Node.js project to this
project.
* Assisting in the implementation of stream providers within Node.js.
* Recommending versions of `readable-stream` to be included in Node.js.
* Messaging about the future of streams to give the community advance
notice of changes.
See [readable-stream](https://github.com/nodejs/readable-stream) for
more details.
