liver-server的使用

本文转载自https://blog.csdn.net/shan1991fei/article/details/79007953

live-server是一款简单的开发用的Http服务器。特点就是在你静态文件进行修改后，有自动加载的功能。

使用它主要有两个原因：

1、对Ajax的操作必须要有服务器的支持，比如用javascript去获取内容。

2、浏览器的自动更新，可以加快开发。你不需要安装任何浏览器插件或手动添加代码片段到您的网页代码里。

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);
