1、静态资源服务器搭建

 1 /*加载模块*/
 2 var express = require(‘express‘);
 3 var http = require(‘http‘);
 4 var path = require(‘path‘);
 5 /*创建服务*/
 6 var app = express();
 7 app.set(‘port‘, 80);
 8 app.use(express.static(path.join(__dirname, ‘public‘)));
 9 /*服务启动*/
10 http.createServer(app).listen(app.get(‘port‘), function() {
11 console.log(‘静态资源服务器已启动,监听端口:‘ + app.get(‘port‘));
12 });

2、PM2能否运行npm start

https://stackoverflow.com/questions/31579509/can-pm2-run-an-npm-start-script

(1) 原生支持

pm2 start npm -- start

(2) shell脚本

wrote shell script below (named start.sh). Because my package.json has prestart option. So I want to run npm start.

1 #!/bin/bash
2 cd /path/to/project
3 npm start

Then, start start.sh by pm2.

pm2 start start.sh --name appNameYouLike

 

3、开发注意事项

1）环境变量 env

分别是 development，testing，production，对应开发，测试和线上，统一通过php打到js变量env中。

可以使用这些变量来控制api的地址，比如如下：

var api_base = (env === ‘production‘) ? ‘//open.che300.com‘ : ‘//open.ceshi.che300.com‘;

2）HTTP和HTTPS问题

我们页面中的前端资源和访问的接口，都统一配置成 // 开头，来根据实际域名切换http协议。

<script type="text/javascript" src="//fezz.che300.com/cves/wap/dist/lib/js/jquery-1.9.1.min.js?v=297"></script>

4、How to remove a auto hyperlinked phone number from Microsoft Edge

https://stackoverflow.com/questions/31867068/how-to-remove-a-auto-hyperlinked-phone-number-from-microsoft-edge

The solution that works for ios devices also works for Microsoft Edge.

Adding the meta tag, 

<meta name="format-detection" content="telephone=no"> 

will prevent the DOM document from being modified when parsed by the browser.
