express-enrouten

express-enrouten

Route configuration middleware for expressjs.

API

app.use(enrouten(options))

var express = require('express'),
    enrouten = require('express-enrouten');

var app = express();
express.use(enrouten({ ... });

#### enrouten(app).withRoutes(options)

var express = require('express'),
    enrouten = require('express-enrouten');

// Legacy API - do not use
//var app = express();
//enrouten(app).withRoutes({ ... });

Configuration

express-enrouten supports routes via configuration and convention.

app.use(enrouten({
        method: 'get',
        path: '/foo',
        handler: function (req, res) {
            // ...
        }
    }]
});

• directory (optional) - String or array of path segments. Specify a directory to have enrouten scan all files recursively to find files that match the controller-spec API.

app.use(enrouten({
    directory: 'controllers'
});

• routes (optional) An array of route definition objects. Each definition must have a path and handler property and can have an optional method property (method defaults to 'GET').

app.use(enrouten({
    routes: [
        { path: '/',    method: 'GET', handler: require('./controllers/index') },
        { path: '/foo', method: 'GET', handler: require('./controllers/foo') }
    ]
});

• index (optional, overrides directory and disables scanning) - String path or array of path segments indicating the file to load which acts as the route 'index' of the application.

// index.js
module.exports = function (app) {

    app.get('/', index);
    app.get('/account', passport.protect, account);

    // etc...
};

Controller Files

A 'controller' is defined as any javascript file (extension of .js) which exports a function that accepts a single argument. NOTE: Any file in the directory tree that matches the API will be invoked/initialized with the express application object.

// Good :)
// controllers/controller.js
module.exports = function (app) {
    app.get('/', function (req, res) {
        // ...
    });
};

// Bad :(
// Function does not get returned when `require`-ed, use `module.exports`
exports = function (app) {
    // ...
};

// Bad :(
// controllers/other-file-in-same-controller-directory.js
modules.exports = function (config) {
    // `config` will be the express application
    // ...
};

// Acceptable :)
// controllers/config.json - A non-js file (ignored)
// controllers/README.txt - A non-js file (ignored)
// controllers/util.js - A js file that has a different API than the spec (ignored)
module.exports = {
    importantHelper: function () {

    }
};
