live-server的使用

本地开发常常需要搭建临时的服务，第一时间我们会想到用http-server。

但现在流行修改文件浏览器自动刷新hot socketing（热拔插），如live-reload。

若想浏览器自动打开项目，用opener。

现在live-server实现了三个插件的所有功能，并且很简单就能启动一个看起来很专业的本地服务

NPM全局安装

npm install -g live-server

其它方式

git clone https://github.com/tapio/live-server
cd live-server
npm install # Local dependencies if you want to hack
npm install -g # Install globally

使用方法：

1. 在项目根目录使用命令

live-server

参数：

--port=NUMBER - select port to use, default: PORT env var or 8080
--host=ADDRESS - select host address to bind to, default: IP env var or 0.0.0.0 (“any address”)
--no-browser - suppress automatic web browser launching
--browser=BROWSER - specify browser to use instead of system default
--quiet | -q - suppress logging
--verbose | -V - more logging (logs all requests, shows all listening IPv4 interfaces, etc.)
--open=PATH - launch browser to PATH instead of server root
--watch=PATH - comma-separated string of paths to exclusively watch for changes (default: watch everything)
--ignore=PATH - comma-separated string of paths to ignore (anymatch-compatible definition)
--ignorePattern=RGXP - Regular expression of files to ignore (ie .*\.jade) (DEPRECATED in favor of --ignore)
--middleware=PATH - path to .js file exporting a middleware function to add; can be a name without path nor extension to reference bundled middlewares in middleware folder
--entry-file=PATH - serve this file (server root relative) in place of missing files (useful for single page apps)
--mount=ROUTE:PATH - serve the paths contents under the defined route (multiple definitions possible)
--spa - translate requests from /abc to /#/abc (handy for Single Page Apps)
--wait=MILLISECONDS - (default 100ms) wait for all changes, before reloading
--htpasswd=PATH - Enables http-auth expecting htpasswd file located at PATH
--cors - Enables CORS for any origin (reflects request origin, requests with credentials are supported)
--https=PATH - PATH to a HTTPS configuration module
--proxy=ROUTE:URL - proxy all requests for ROUTE to URL
--help | -h - display terse usage hint and exit
--version | -v - display version and exit

2.  把它放在 package.json 的 scripts 下的 server 中

"scripts": {
  "server": "live-server ./ --port=8081"
}

运行

npm run server

3. node

var liveServer = require("live-server");
 
var params = {
    port: 8181, // Set the server port. Defaults to 8080. 
    host: "0.0.0.0", // Set the address to bind to. Defaults to 0.0.0.0 or process.env.IP. 
    root: "/public", // Set root directory that's being served. Defaults to cwd. 
    open: false, // When false, it won't load your browser by default. 
    ignore: 'scss,my/templates', // comma-separated string for paths to ignore 
    file: "index.html", // When set, serve this file for every 404 (useful for single-page applications) 
    wait: 1000, // Waits for all changes, before reloading. Defaults to 0 sec. 
    mount: [['/components', './node_modules']], // Mount a directory to a route. 
    logLevel: 2, // 0 = errors only, 1 = some, 2 = lots 
    middleware: [function(req, res, next) { next(); }] // Takes an array of Connect-compatible middleware that are injected into the server middleware stack 
};
liveServer.start(params);
