|
|
|
|
```bash
|
|
npm install --save readable-stream
|
|
```
|
|
|
|
This package is a mirror of the streams implementations in Node.js.
|
|
|
|
Full documentation may be found on the [Node.js website](https://nodejs.org/dist/v10.15.3/docs/api/stream.html).
|
|
|
|
If you want to guarantee a stable streams base, regardless of what version of
|
|
Node you, or the users of your libraries are using, use **readable-stream** *only* and avoid the *"stream"* module in Node-core, for background see [this blogpost](http://r.va.gg/2014/06/why-i-dont-use-nodes-core-stream-module.html).
|
|
|
|
As of version 2.0.0 **readable-stream** uses semantic versioning.
|
|
|
|
## Version 3.x.x
|
|
|
|
v3.x.x of `readable-stream` supports Node 6, 8, and 10, as well as
|
|
evergreen browsers, IE 11 and latest Safari. The breaking changes
|
|
introduced by v3 are composed by the combined breaking changes in [Node v9](https://nodejs.org/en/blog/release/v9.0.0/)
|
|
and [Node v10](https://nodejs.org/en/blog/release/v10.0.0/), as follows:
|
|
|
|
1. Error codes: https://github.com/nodejs/node/pull/13310,
|
|
https://github.com/nodejs/node/pull/13291,
|
|
https://github.com/nodejs/node/pull/16589,
|
|
https://github.com/nodejs/node/pull/15042,
|
|
https://github.com/nodejs/node/pull/15665,
|
|
https://github.com/nodejs/readable-stream/pull/344
|
|
2. 'readable' have precedence over flowing
|
|
https://github.com/nodejs/node/pull/18994
|
|
3. make virtual methods errors consistent
|
|
https://github.com/nodejs/node/pull/18813
|
|
4. updated streams error handling
|
|
https://github.com/nodejs/node/pull/18438
|
|
5. writable.end should return this.
|
|
https://github.com/nodejs/node/pull/18780
|
|
6. readable continues to read when push('')
|
|
https://github.com/nodejs/node/pull/18211
|
|
7. add custom inspect to BufferList
|
|
https://github.com/nodejs/node/pull/17907
|
|
8. always defer 'readable' with nextTick
|
|
https://github.com/nodejs/node/pull/17979
|
|
|
|
## Version 2.x.x
|
|
|
|
v2.x.x of `readable-stream` supports all Node.js version from 0.8, as well as
|
|
evergreen browsers and IE 10 & 11.

# Usage
|
|
|
|
You can swap your `require('stream')` with `require('readable-stream')`
|
|
without any changes, if you are just using one of the main classes and
|
|
functions.
|
|
|
|
```js
|
|
const {
|
|
Readable,
|
|
Writable,
|
|
Transform,
|
|
Duplex,
|
|
pipeline,
|
|
finished
|
|
} = require('readable-stream')
|
|
````
|
|
|
|
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.
|
|
|
|
# Streams Working Group
|
|
|
|
`readable-stream` 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.
