### 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.

# readable-stream
|

|

***Node.js core streams for userland*** [](https://travis-ci.com/nodejs/readable-stream)
|
||||
|
||||
|
||||
[](https://nodei.co/npm/readable-stream/)
|
||||
[](https://nodei.co/npm/readable-stream/)
|
||||
|
||||
|
||||
[](https://saucelabs.com/u/readabe-stream)
|
||||
|
||||
```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/v10.15.2/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.

|

// 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.
