我知道这个问题已经有5年多了，给出的答案也很好，但我想要一些更强大的express，所以我为npm创建了express-map2包。我打算把它简单地命名为express-map，但是雅虎的人已经有了这个名字的包，所以我不得不重命名我的包。

1. 基本用法:

app.js (or whatever you call it)

var app = require('express'); // 1. include express

app.set('controllers',__dirname+'/controllers/');// 2. set path to your controllers.

require('express-map2')(app); // 3. patch map() into express

app.map({
    'GET /':'test',
    'GET /foo':'middleware.foo,test',
    'GET /bar':'middleware.bar,test'// seperate your handlers with a comma. 
});

控制器的使用方法:

//single function
module.exports = function(req,res){

};

//export an object with multiple functions.
module.exports = {

    foo: function(req,res){

    },

    bar: function(req,res){

    }

};

2. 高级用法，带前缀:

app.map('/api/v1/books',{
    'GET /': 'books.list', // GET /api/v1/books
    'GET /:id': 'books.loadOne', // GET /api/v1/books/5
    'DELETE /:id': 'books.delete', // DELETE /api/v1/books/5
    'PUT /:id': 'books.update', // PUT /api/v1/books/5
    'POST /': 'books.create' // POST /api/v1/books
});

正如您所看到的，这节省了大量的时间，并使应用程序的路由非常易于编写、维护和理解。它支持所有表示支持的HTTP动词，以及特殊的.all()方法。

我建议使用glob来完成这个任务。

var glob = require( 'glob' )
  , path = require( 'path' );

glob.sync( './routes/**/*.js' ).forEach( function( file ) {
  require( path.resolve( file ) );
});

在这个glob解决方案上展开。如果你想将所有模块从一个目录导入到index.js中，然后将该index.js导入到应用程序的另一部分，那么就这样做。注意，stackoverflow使用的高亮显示引擎不支持模板文字，因此这里的代码可能看起来很奇怪。

const glob = require("glob");

let allOfThem = {};
glob.sync(`${__dirname}/*.js`).forEach((file) => {
  /* see note about this in example below */
  allOfThem = { ...allOfThem, ...require(file) };
});
module.exports = allOfThem;

完整的示例

目录结构

globExample/example.js
globExample/foobars/index.js
globExample/foobars/unexpected.js
globExample/foobars/barit.js
globExample/foobars/fooit.js

globExample - js操作。

const { foo, bar, keepit } = require('./foobars/index');
const longStyle = require('./foobars/index');

console.log(foo()); // foo ran
console.log(bar()); // bar ran
console.log(keepit()); // keepit ran unexpected

console.log(longStyle.foo()); // foo ran
console.log(longStyle.bar()); // bar ran
console.log(longStyle.keepit()); // keepit ran unexpected

globExample foobars / index . js

const glob = require("glob");
/*
Note the following style also works with multiple exports per file (barit.js example)
but will overwrite if you have 2 exports with the same
name (unexpected.js and barit.js have a keepit function) in the files being imported. As a result, this method is best used when
your exporting one module per file and use the filename to easily identify what is in it.

Also Note: This ignores itself (index.js) by default to prevent infinite loop.
*/

let allOfThem = {};
glob.sync(`${__dirname}/*.js`).forEach((file) => {
  allOfThem = { ...allOfThem, ...require(file) };
});

module.exports = allOfThem;

globExample foobars /无法js。

exports.keepit = () => 'keepit ran unexpected';

globExample foobars / barit js。

exports.bar = () => 'bar run';

exports.keepit = () => 'keepit ran';

globExample foobars / fooit js。

exports.foo = () => 'foo ran';

在安装了glob的项目中，运行node example.js

$ node example.js
foo ran
bar run
keepit ran unexpected
foo ran
bar run
keepit ran unexpected

基于@tbranyen的解决方案，我创建了一个index.js文件，在当前文件夹下加载任意javascript作为导出的一部分。

// Load `*.js` under current directory as properties
//  i.e., `User.js` will become `exports['User']` or `exports.User`
require('fs').readdirSync(__dirname + '/').forEach(function(file) {
  if (file.match(/\.js$/) !== null && file !== 'index.js') {
    var name = file.replace('.js', '');
    exports[name] = require('./' + file);
  }
});

然后，您可以从其他任何地方要求这个目录。

用下面的代码在文件夹中创建一个index.js文件:

const fs = require('fs')    
const files = fs.readdirSync('./routes')
for (const file of files) {
  require('./'+file)
}

然后你可以简单地用require("./routes")加载所有文件夹

另一种选择是使用require-dir包，它允许您执行以下操作。它也支持递归。

var requireDir = require('require-dir');
var dir = requireDir('./path/to/dir');
