route(controllerDirectory[, alias][, unknowRouteHandler]

  • controllerDirectory is a string of controller directory.
  • alias is a object for alias to a path or function.
  • unknowRouteHandler is a function to handler the unknow route.

Usage

// File: app.js

var express = require('express'),
    app = express(),
    route = require('express-route-tree');

app.use(route(__dirname + '/controller'));
/*
// Advanced Settings
var fileRouter = ['robots.txt'],
    shortAddress = ['mon', 'tus'],
    regionRoute = { china: { id: '1', name: '中国' } };
app.use(route(__dirname + '/controller', {
    season: '/index/season', // GET /season === GET /index/season
    '/a/b': '/index/season'  // GET /a/b === GET /index/season
}, function(req, res, next, controller) {
    var pathname = req.path.substring(1);
    if (~fileRouter.indexOf(pathname)) {
        return res.sendFile(pathname, { maxAge: 3600 * 24 * 1000 });
    } else if (~shortAddress.indexOf(pathname))) {
        // some short address
        return controller.index.season(req, res, next, shortAddress[pathname] + 1);
    } else if (regionRoute[pathname]) {
        return controller.index.region(req, res, next, regionRoute[pathname].id, regionRoute[pathname].name);
    } else {
        return next('No such route.');
    }
});
*/

// Add alias: `{ season: 'index.season' }`, and
// GET /index/season/2 is equivalent to GET /season/2

// Add alias: `{ '/a/b': '/index/season' }`, and
// GET /index/season/2 is equivalent to GET /a/b/2

// try it:
// console.log(route.controller);
// File: controller/app/list.js

/**
 * Normal Get Request, Support urls:
 * 1. /app/list => page: undefined | second: undefind
 * 2. /app/list/0 => page: 0 | second: undefined
 * 3. /app/list/1.html => page: 1 | second: undefined
 * 4. /app/list/1/a => page: 1 | second: a
 */
exports.index = function(req, res, next, page, second) {
    res.send('Page: ' + page + ' Second: ' + second);
    res.end();
};

/**
 * @Caution:
 *  if you want to use index with other(not get) request method.
 *  you must use full path: /app/list/index/1/a
 *  otherwise, request will be transfered to index function.
 *  Also, if there is not matched function, such as '/app/test'(no `exports.test = function(){}` in app.js),
 *  Then, router will send this request to `app.index` function,
 *  And put the `test` as the four argument, like `function(req, res, next, test)`
 */

/**
 * For POST Request. Support urls:
 * 1. /app/list/set => page: undefined | second: undefind
 * 2. /app/list/set/0 => page: 0 | second: undefined
 * 3. /app/list/set/1 => page: 1 | second: undefined
 * 4. /app/list/set/1/a => page: 1 | second: a
 */
exports.postSet = function(req, res, next, page, second) {
    res.send('Page: ' + page + ' Second: ' + second);
    res.end();
}

/**
 * For PUT Request. Support urls:
 * 1. /app/list/setapp => page: undefined | second: undefind
 * 2. /app/list/setapp/0 => page: 0 | second: undefined
 * 3. /app/list/setapp/1 => page: 1 | second: undefined
 * 4. /app/list/setapp/1/a => page: 1 | second: a
 */
exports.putSetapp = function(req, res, next, page, second) {
    res.send('Page: ' + page + ' Second: ' + second);
    res.end();
}

// And also support any method from request header.
// like: exports.deleteApp = function(req, res, next, ...) { ... }
