෴ browserver-client ෴
This is a browserver client, for the browser.
browserver-client exposes the important bits of the node.js http API in the browser, allowing it to receive incoming HTTP requests and make outgoing HTTP requests via WebSockets.
This library, along with browserver-node, is all the code you need to set up your own browserver.
Example
In index.html:
<!doctype html>
<html>
<head>
<title>My Browserver App</title>
<script src="/optional/path/to/websocket-shim"></script>
<script src="/path/to/browserver"></script>
<script src="/app.js"></script>
</head>
</html>In app.js:
// to handle incoming HTTP requests,
// use the standard node.js http.Server API
var server = http.createServer(function(req, res) {
if (req.method != "GET") {
res.writeHead(405, {"Content-Type": "text/plain"})
return res.end("Method not allowed")
}
var pathname = req.url.split("?")[0]
if (pathname != "/hello") {
res.writeHead(404, {"Content-Type": "text/plain"})
return res.end("Not found.")
}
res.writeHead(200, {"Content-Type": "text/plain"})
res.end("Hello, world!")
})
// establish a WebSocket (or compatible) connection,
// in this case using engine.io
var ws = new eio.Socket({host: "myserver.com"})
// bind the browserver HTTP server to the WebSocket
// and wait for connections from the browserver proxy!
server.listen(ws)
// to make outgoing HTTP requests w/o cross-domain issues,
// use http.get or http.request
http.get("http://www.google.com/index.html", function(res) {
console.log("Google answered back!")
})API
The browserver-client API is basically a port of the node.js http API, with a few caveats:
Streaming is not supported. This means a
ServerRequestorClientResponsewill only emit onedataevent, and that multiple calls to thewritemethod of aServerResponseorClientRequestwill be buffered locally and sent whenendis called. Thedataevents are provided for compatibility, but aren't technically needed, since the body itself is stored on thebodyproperty of theServerRequestorClientResponse.The aspects of the node.js implementation that don't map well to the browser (such as
writeContinueandaddTrailersmethods, and client agents) have been omitted.
Otherwise, if there is a method or behavior that differs from what you'd expect on node.js, please file an issue.
TODO
- Include more client tests in the phantomjs tests run for browserver-node
- Make an exhaustive list of the HTTP APIs supported and not supported.
- Consider enabling support for
addEventListenerevents.
