An HTTP/2 server implementation for node.js, developed as a Google Summer of Code project.

I post weekly status updates on my blog. Short version: an example server and client can be run. A more node-like API, more documentation and tests are coming soon.

Using npm:

npm install http2

API documentation is coming later, when the public API becomes usable.

An example server (serving up static files from its own directory) and client are available in the example directory.

Running the server:

$ node ./example/server.js
Listening on localhost:8080, serving up files from ./example

Downloading the server's source code from the server (the downloaded content gets pumped out to the standard error output):

$ node ./example/client.js 'http://localhost:8080/server.js' 2>/tmp/server.js

There's a few library you will need to have installed to do anything described in the following sections. After installing node-http2, run npm install in its directory to install development dependencies.

Used libraries:

• mocha for tests
• chai for assertions
• istanbul for code coverage analysis
• docco for developer documentation
• bunyan for logging

The developer documentation is located in the doc directory. The docs are usually updated only before releasing a new version. To regenerate them manually, run npm run-script prepublish. There's a hosted version which is located here.

It's easy, just run npm test. The tests are written in BDD style, so they are a good starting point to understand the code.

To generate a code coverage report, run npm test --coverage. Code coverage summary as of version 0.0.6:

Statements   : 91.18% ( 775/850 )
Branches     : 84.69% ( 249/294 )
Functions    : 88.03% ( 103/117 )
Lines        : 91.18% ( 775/850 )

There's a hosted version of the detailed (line-by-line) coverage report here.

Logging is turned off by default. To turn it on, set the HTTP2_LOG environment variable to fatal, error, warn, info, debug or trace (the logging level). Log output is in JSON format, and can be pretty printed using the bunyan command line tool.

For example, running the test client with debug level logging output:

HTTP2_LOG=debug node ./example/client.js 'http://localhost:8080/server.js' 2>/tmp/server.js | bunyan
