在 node.js 的 express web 框架中自动注册路由

var express = require(‘express‘);
var fs = require(‘fs‘);

var router = express.Router();
var files = fs.readdirSync(__dirname);

files
    .filter(function(file, index){
        return file !== ‘loader.js‘;
    })
    .forEach(function(file, index){
        var route = require(‘./‘ + file.replace(‘.js‘, ‘‘));
        if(file === ‘index.js‘){
            router.use(‘/‘, route);
        }else{
            router.use(‘/api/‘ + file.replace(‘.js‘, ‘‘), route);
        }
    });

module.exports = router;

var loader = require(‘./routes/loader‘);
app.use(‘/‘, loader);
