+node-http2
+==========
+
+An HTTP/2 ([RFC 7540](http://tools.ietf.org/html/rfc7540))
+client and server implementation for node.js.
+
+![Travis CI status](https://travis-ci.org/molnarg/node-http2.svg?branch=master)
+
+**NOTE WELL** This package is officially deprecated. As of node 9.0.0, there is an 'http2' package built-in. You should use that one instead.
+
+Installation
+------------
+
+```
+npm install http2
+```
+
+API
+---
+
+The API is very similar to the [standard node.js HTTPS API](http://nodejs.org/api/https.html). The
+goal is the perfect API compatibility, with additional HTTP2 related extensions (like server push).
+
+Detailed API documentation is primarily maintained in the `lib/http.js` file and is [available in
+the wiki](https://github.com/molnarg/node-http2/wiki/Public-API) as well.
+
+Examples
+--------
+
+### Using as a server ###
+
+```javascript
+var options = {
+ key: fs.readFileSync('./example/localhost.key'),
+ cert: fs.readFileSync('./example/localhost.crt')
+};
+
+require('http2').createServer(options, function(request, response) {
+ response.end('Hello world!');
+}).listen(8080);
+```
+
+### Using as a client ###
+
+```javascript
+require('http2').get('https://localhost:8080/', function(response) {
+ response.pipe(process.stdout);
+});
+```
+
+### Simple static file server ###
+
+An simple static file server serving up content from its own directory is available in the `example`
+directory. Running the server:
+
+```bash
+$ node ./example/server.js
+```
+
+### Simple command line client ###
+
+An example client is also available. Downloading the server's own source code from the server:
+
+```bash
+$ node ./example/client.js 'https://localhost:8080/server.js' >/tmp/server.js
+```
+
+### Server push ###
+
+For a server push example, see the source code of the example
+[server](https://github.com/molnarg/node-http2/blob/master/example/server.js) and
+[client](https://github.com/molnarg/node-http2/blob/master/example/client.js).
+
+Status
+------
+
+* ALPN is only supported in node.js >= 5.0
+* Upgrade mechanism to start HTTP/2 over unencrypted channel is not implemented yet
+ (issue [#4](https://github.com/molnarg/node-http2/issues/4))
+* Other minor features found in
+ [this list](https://github.com/molnarg/node-http2/issues?labels=feature) are not implemented yet
+
+Development
+-----------
+
+### Development dependencies ###
+
+There's a few library you will need to have installed to do anything described in the following
+sections. After installing/cloning node-http2, run `npm install` in its directory to install
+development dependencies.
+
+Used libraries:
+
+* [mocha](http://visionmedia.github.io/mocha/) for tests
+* [chai](http://chaijs.com/) for assertions
+* [istanbul](https://github.com/gotwarlost/istanbul) for code coverage analysis
+* [docco](http://jashkenas.github.io/docco/) for developer documentation
+* [bunyan](https://github.com/trentm/node-bunyan) for logging
+
+For pretty printing logs, you will also need a global install of bunyan (`npm install -g bunyan`).
+
+### Developer documentation ###
+
+The developer documentation is generated from the source code using docco and can be viewed online
+[here](http://molnarg.github.io/node-http2/doc/). If you'd like to have an offline copy, just run
+`npm run-script doc`.
+
+### Running the tests ###
+
+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.
+
+### Test coverage ###
+
+To generate a code coverage report, run `npm test --coverage` (which runs very slowly, be patient).
+Code coverage summary as of version 3.0.1:
+```
+Statements : 92.09% ( 1759/1910 )
+Branches : 82.56% ( 696/843 )
+Functions : 91.38% ( 212/232 )
+Lines : 92.17% ( 1753/1902 )
+```
+
+There's a hosted version of the detailed (line-by-line) coverage report
+[here](http://molnarg.github.io/node-http2/coverage/lcov-report/lib/).
+
+### Logging ###
+
+Logging is turned off by default. You can turn it on by passing a bunyan logger as `log` option when
+creating a server or agent.
+
+When using the example server or client, it's very easy to turn logging on: set the `HTTP2_LOG`
+environment variable to `fatal`, `error`, `warn`, `info`, `debug` or `trace` (the logging level).
+To log every single incoming and outgoing data chunk, use `HTTP2_LOG_DATA=1` besides
+`HTTP2_LOG=trace`. Log output goes to the standard error output. If the standard error is redirected
+into a file, then the log output is in bunyan's JSON format for easier post-mortem analysis.
+
+Running the example server and client with `info` level logging output:
+
+```bash
+$ HTTP2_LOG=info node ./example/server.js
+```

+// Public API
+// ==========
+
+// The main governing power behind the http2 API design is that it should look very similar to the
+// existing node.js [HTTPS API][1] (which is, in turn, almost identical to the [HTTP API][2]). The
+// additional features of HTTP/2 are exposed as extensions to this API. Furthermore, node-http2
+// should fall back to using HTTP/1.1 if needed. Compatibility with undocumented or deprecated
+// elements of the node.js HTTP/HTTPS API is a non-goal.
+//
+// Additional and modified API elements
+// ------------------------------------
+//
+// - **Class: http2.Endpoint**: an API for using the raw HTTP/2 framing layer. For documentation
+// see [protocol/endpoint.js](protocol/endpoint.html).
+//
+// - **Class: http2.Server**
+// - **Event: 'connection' (socket, [endpoint])**: there's a second argument if the negotiation of
+// HTTP/2 was successful: the reference to the [Endpoint](protocol/endpoint.html) object tied to the
+// socket.
+//
+// - **http2.createServer(options, [requestListener])**: additional option:
+// - **log**: an optional [bunyan](https://github.com/trentm/node-bunyan) logger object
+//
+// - **Class: http2.ServerResponse**
+// - **response.push(options)**: initiates a server push. `options` describes the 'imaginary'
+// request to which the push stream is a response; the possible options are identical to the
+// ones accepted by `http2.request`. Returns a ServerResponse object that can be used to send
+// the response headers and content.
+//
+// - **Class: http2.Agent**
+// - **new Agent(options)**: additional option:
+// - **log**: an optional [bunyan](https://github.com/trentm/node-bunyan) logger object
+// - **agent.sockets**: only contains TCP sockets that corresponds to HTTP/1 requests.
+// - **agent.endpoints**: contains [Endpoint](protocol/endpoint.html) objects for HTTP/2 connections.
+//
+// - **http2.request(options, [callback])**:
+// - similar to http.request
+//
+// - **http2.get(options, [callback])**:
+// - similar to http.get
+//
+// - **Class: http2.ClientRequest**
+// - **Event: 'socket' (socket)**: in case of an HTTP/2 incoming message, `socket` is a reference
+// to the associated [HTTP/2 Stream](protocol/stream.html) object (and not to the TCP socket).
+// - **Event: 'push' (promise)**: signals the intention of a server push associated to this
+// request. `promise` is an IncomingPromise. If there's no listener for this event, the server
+// push is cancelled.
+// - **request.setPriority(priority)**: assign a priority to this request. `priority` is a number
+// between 0 (highest priority) and 2^31-1 (lowest priority). Default value is 2^30.
+//
+// - **Class: http2.IncomingMessage**
+// - has two subclasses for easier interface description: **IncomingRequest** and
+// **IncomingResponse**
+// - **message.socket**: in case of an HTTP/2 incoming message, it's a reference to the associated
+// [HTTP/2 Stream](protocol/stream.html) object (and not to the TCP socket).
+//
+// - **Class: http2.IncomingRequest (IncomingMessage)**
+// - **message.url**: in case of an HTTP/2 incoming request, the `url` field always contains the
+// path, and never a full url (it contains the path in most cases in the HTTPS api as well).
+// - **message.scheme**: additional field. Mandatory HTTP/2 request metadata.
+// - **message.host**: additional field. Mandatory HTTP/2 request metadata. Note that this
+// replaces the old Host header field, but node-http2 will add Host to the `message.headers` for
+// backwards compatibility.
+//
+// - **Class: http2.IncomingPromise (IncomingRequest)**
+// - contains the metadata of the 'imaginary' request to which the server push is an answer.
+// - **Event: 'response' (response)**: signals the arrival of the actual push stream. `response`
+// is an IncomingResponse.
+// - **Event: 'push' (promise)**: signals the intention of a server push associated to this
+// request. `promise` is an IncomingPromise. If there's no listener for this event, the server
+// push is cancelled.
+// - **promise.cancel()**: cancels the promised server push.
+// - **promise.setPriority(priority)**: assign a priority to this push stream. `priority` is a
+// number between 0 (highest priority) and 2^31-1 (lowest priority). Default value is 2^30.
+//
+// API elements not yet implemented
+// --------------------------------
+//
+// - **Class: http2.Server**
+// - **server.maxHeadersCount**
+//
+// API elements that are not applicable to HTTP/2
+// ----------------------------------------------
+//
+// The reason may be deprecation of certain HTTP/1.1 features, or that some API elements simply
+// don't make sense when using HTTP/2. These will not be present when a request is done with HTTP/2,
+// but will function normally when falling back to using HTTP/1.1.
+//
+// - **Class: http2.Server**
+// - **Event: 'checkContinue'**: not in the spec
+// - **Event: 'upgrade'**: upgrade is deprecated in HTTP/2
+// - **Event: 'timeout'**: HTTP/2 sockets won't timeout because of application level keepalive
+// (PING frames)
+// - **Event: 'connect'**: not yet supported
+// - **server.setTimeout(msecs, [callback])**
+// - **server.timeout**
+//
+// - **Class: http2.ServerResponse**
+// - **Event: 'close'**
+// - **Event: 'timeout'**
+// - **response.writeContinue()**
+// - **response.writeHead(statusCode, [reasonPhrase], [headers])**: reasonPhrase will always be
+// ignored since [it's not supported in HTTP/2][3]
+// - **response.setTimeout(timeout, [callback])**
+//
+// - **Class: http2.Agent**
+// - **agent.maxSockets**: only affects HTTP/1 connection pool. When using HTTP/2, there's always
+// one connection per host.
+//
+// - **Class: http2.ClientRequest**
+// - **Event: 'upgrade'**
+// - **Event: 'connect'**
+// - **Event: 'continue'**
+// - **request.setTimeout(timeout, [callback])**
+// - **request.setNoDelay([noDelay])**
+// - **request.setSocketKeepAlive([enable], [initialDelay])**

+// ====================

+// stream (TCP stream). It operates by sending and receiving frames and is implemented as a
+// [Flow](flow.html) subclass.
+
+var Flow = require('./flow').Flow;

+exports.Connection = Connection;
+
+// Public API
+// ----------
+
+// * **new Connection(log, firstStreamId, settings)**: create a new Connection
+//
+// * **Event: 'error' (type)**: signals a connection level error made by the other end
+//
+// * **Event: 'peerError' (type)**: signals the receipt of a GOAWAY frame that contains an error
+// code other than NO_ERROR
+//
+// * **Event: 'stream' (stream)**: signals that there's an incoming stream
+//
+// * **createStream(): stream**: initiate a new stream
+//
+// * **set(settings, callback)**: change the value of one or more settings according to the
+// key-value pairs of `settings`. The callback is called after the peer acknowledged the changes.
+//
+// * **ping([callback])**: send a ping and call callback when the answer arrives
+//
+// * **close([error])**: close the stream with an error code
+
+// Constructor
+// -----------
+
+// The main aspects of managing the connection are:

+// [1]: https://tools.ietf.org/html/rfc7540#section-6.9.2

+// with the given `flowControlId` (or every update frame if not given)

+// * **_send()**: called when more frames should be pushed. The child class is expected to override

+// This is an implementation of the [HTTP/2][http2]

+//
+// The main building blocks are [node.js streams][node-stream] that are connected through pipes.
+//
+// The main components are:
+//
+// * [Endpoint](endpoint.html): represents an HTTP/2 endpoint (client or server). It's
+// responsible for the the first part of the handshake process (sending/receiving the
+// [connection header][http2-connheader]) and manages other components (framer, compressor,
+// connection, streams) that make up a client or server.
+//
+// * [Connection](connection.html): multiplexes the active HTTP/2 streams, manages connection
+// lifecycle and settings, and responsible for enforcing the connection level limits (flow
+// control, initiated stream limit)
+//
+// * [Stream](stream.html): implementation of the [HTTP/2 stream concept][http2-stream].
+// Implements the [stream state machine][http2-streamstate] defined by the standard, provides
+// management methods and events for using the stream (sending/receiving headers, data, etc.),
+// and enforces stream level constraints (flow control, sending only legal frames).
+//
+// * [Flow](flow.html): implements flow control for Connection and Stream as parent class.
+//
+// * [Compressor and Decompressor](compressor.html): compression and decompression of HEADER and
+// PUSH_PROMISE frames
+//
+// * [Serializer and Deserializer](framer.html): the lowest layer in the stack that transforms
+// between the binary and the JavaScript object representation of HTTP/2 frames

+// The Stream class
+// ================
+
+// Stream is a [Duplex stream](https://nodejs.org/api/stream.html#stream_class_stream_duplex)
+// subclass that implements the [HTTP/2 Stream](https://tools.ietf.org/html/rfc7540#section-5)
+// concept. It has two 'sides': one that is used by the user to send/receive data (the `stream`
+// object itself) and one that is used by a Connection to read/write frames to/from the other peer
+// (`stream.upstream`).
+
+var Duplex = require('stream').Duplex;
+
+exports.Stream = Stream;
+
+// Public API
+// ----------
+
+// * **new Stream(log, connection)**: create a new Stream
+//
+// * **Event: 'headers' (headers)**: signals incoming headers
+//
+// * **Event: 'promise' (stream, headers)**: signals an incoming push promise
+//
+// * **Event: 'priority' (priority)**: signals a priority change. `priority` is a number between 0
+// (highest priority) and 2^31-1 (lowest priority). Default value is 2^30.
+//
+// * **Event: 'error' (type)**: signals an error
+//
+// * **headers(headers)**: send headers
+//
+// * **promise(headers): Stream**: promise a stream
+//
+// * **priority(priority)**: set the priority of the stream. Priority can be changed by the peer
+// too, but once it is set locally, it can not be changed remotely.
+//
+// * **reset(error)**: reset the stream with an error code
+//
+// * **upstream**: a [Flow](flow.js) that is used by the parent connection to write/read frames
+// that are to be sent/arrived to/from the peer and are related to this stream.
