express-jsxtransform

Middleware that compiles jsx on-the-fly. Intended to be used in a development setting with the express.static middleware, but should work with any middleware further down the stack, even an http proxy.

The response will be rewritten under these circumstances:

• If the response is a file with the .js extension and has the /** @jsx ... */ annotation on the first line.
• If the response is a file with the .jsx extension. In this case the annotation is optional.

jsxtranform plays nice with conditional GET. If the original response has an ETag, jsxtransform will add to it so the ETag of the compiled response never clashes with the original ETag. That prevents the middleware issuing the original response from being confused into sending a false positive 304 Not Modified if jsxtransform is turned off or removed from the stack later.

Installation

Make sure you have node.js and npm installed, then run:

npm install express-jsxtransform

Example usage

var express = require('express'),
    jsxtransform = require('express-jsxtransform'),
    root = '/path/to/my/static/files';
 
express.createServer()
    .use(jsxtransform())
    .use(express.static(root))
    .listen(1337);
