Generates an API document from code built with Express

A simple wrapper for generating REST API documentation for Express-based projects. This combines the parsing of [dox][1] with a [Handlebars][2] template engine to produce HTML documentation describing a REST interface.

Keep in mind, the project makes some assumptions, so you probably want to really just clone this project and change it.

You can install by either running the following command:

npm install express-api-docs

Or adding the appropriate line to your package.json file.

Create a JavaScript file, like that contains the following:

   var api = require('express-api-docs');
   api.generate('router.js', 'public/api.html');

The api variable has a single function, generate(), which takes two parameters:

  • Input file specifies a router script (see below).
  • Output file where the HTML code should be placed.

Currently, the project assumes that your routes are not in your main app.js file, but instead live is a separate file that the app.js file calls. Something like:

 * Routes all API requests to particular functions.
 * This file would be referenced by the `app.js` file, as:
 *      var app    = express.createServer();
 *      var routes = require('./router');
 * And called:
 *      routes.setup(app);

var index = require('./routes/index');
var user = require('./routes/user');

module.exports.setup = function( app ) {
    app.get(   '/',            index.index );
    app.get(   '/user',        user.getAllUsers);  '/user',        user.createUser);  
    app.get(   '/user/:email', user.getUser ); 
    app.delete('/user/:email', user.deleteUser);        
    app.put(   '/user/:email', user.updateUser );

The parsing code for analyzing the routes is currently very brittle and will be the first piece to be retooled.
