The streams standard provides APIs for creating, composing, and consuming streams of data. These streams are designed to map efficiently to low-level I/O primitives, and allow easy composition with built-in backpressure and queuing.
The main spec is available at https://streams.spec.whatwg.org/, generated from the index.bs file. We are also working on a number of potential extensions: see BinaryExtension.md and TeeStream.md.
Snapshots of any given commit or branch are available at specially-crafted URLs:
- https://streams.spec.whatwg.org/commit-snapshots/ contains snapshots of any given commit
- https://streams.spec.whatwg.org/branch-snapshots/ contains snapshots of the latest commit to any given branch
This repository also includes a polyfill and test suite under reference-implementation/. See the README under that directory for more details. The test suite is automatically deployed, in a form viable for running against browsers, to https://streams.spec.whatwg.org/tests/.
Building the spec is a two-step process. First, the majority of the conversion work is done via Bikeshed. Second, we run a custom portion of the Ecmarkup pipeline to convert the algorithms from Ecmarkdown syntax into HTML, and to automatically add cross-references. This second step requires io.js to be installed.
To run Bikeshed locally, install Bikeshed and then run bikeshed spec in the working directory.
Alternately, you can use the command
curl https://api.csswg.org/bikeshed/ -F md-Text-Macro="SNAPSHOT-LINK dummy" -F file=@index.bs > index.tmp.html
to use Bikeshed's web interface without installing anything.
To run the Ecmarkup step, be sure you've done npm install in the root directory, then run
npm run ecmarkupify index.tmp.html index.html
To get the full build experience, including commit and branch snapshots, you can run
bash ./deploy.sh --local
This will output a bunch of files to the streams.spec.whatwg.org directory, equaling those that would be uploaded to the server on deploy.
If you have Bikeshed installed locally, and have run npm install, you can try running
npm run local-watch
to start a watcher on index.bs that will update index.html as you edit.
