EXPRESS.JS再出发

那个那个MEAN的书，看得七七八八，有了大概，现在就要一样一样的加深记忆啦。。

EXPRSS.JS的东东，网上有现成入门书籍：

 

第一期代码测试：

 

var express = require('express');var app = express();var handlebars = require('express3-handlebars').create({defaultLayout: 'main'}); app.engine('handlebars', handlebars.engine); app.set('view engine', 'handlebars');app.set('port', process.env.PORT || 3000);app.use(express.static(__dirname + '/public'));var fortunes = ["Conquer your fears or they will conquer you.","Rivers need springs.","Do not fear what you don't know.","You will have a pleasant surprise.","Whenever possible, keep it simple.", ];app.get('/', function(req, res) {res.render('home'); });app.get('/about', function(req, res) {var randomFortune = fortunes[Math.floor(Math.random() * fortunes.length)];res.render('about', {fortune: randomFortune}); });app.use(function(req, res) {res.status(404);res.render('404'); });app.use(function(err, req, res, next) {console.error(err.stack);res.status(500);res.render('500'); });app.listen(app.get('port'), function() {console.log('Express started on http://localhost: ' + app.get('port') + '; press Ctrl-C teminate.'); });
