例如,我想创建一些使用Passport的中间件,但我不想在使用此自定义中间件的应用程序中要求Passport。我相信我可以做到以下几点来实现这一目标。这是对的吗?有更好的方法吗?
someModule.js
var express = require('express'),
passport = require('passport');
exports.someMiddleware = function(app) {
app.use(passport.initialize());
app.use(passport.session());
return function(req, res, next) {
// Do something
next();
}
}
app.js
var express = require('express');
var someModule = require('./someModule');
app = express();
app.use(someModule.someMiddleware(app))
而不是......
someModule.js
var express = require('express'),
passport = require('passport');
exports.someMiddleware = function(app) {
return function(req, res, next) {
// Do something
next();
}
}
app.js
var express = require('express'),
passport = require('passport');
var someModule = require('./someModule');
app = express();
app.use(passport.initialize());
app.use(passport.session());
app.use(someModule.someMiddleware())

我建议使用嵌入式应用程序来保持代码组织良好和可重用。保持嵌入式应用中的路由尽可能短,以便使用它们的主应用可以设置适当的基本路径。
module.js
var express = require('express');
var passport = require('passport');
var controller = module.exports = express();
controller.use(passport.initialize());
controller.use(passport.session());
// Login
controller.post('/', function (request, response, next) { /* ... */ });
// Logout
controller.del('/', function (request, response, next) { /* ... */ });
app.js
var app = express();
var controller = require('./controllers/module');
app.use('/authentication', controller);
