Webpack-dev-server API

webpack-dev-server提供了一个Node.js API，可以直接在Node.js运行时中使用。

Installation

要开始使用webpack-dev-server Node.js API，首先要安装webpack和webpack-dev-server：

npm install --save-dev webpack webpack-dev-server

然后在Node.js脚本中引入这些模块：

const Webpack = require(webpack);
const WebpackDevServer = require(webpack-dev-server);

Start

使用下面的代码告诉webpack-dev-server实例启动服务器。

server.js

const Webpack = require(webpack);
const WebpackDevServer = require(webpack-dev-server);
const webpackConfig = require(./webpack.config.js);

const compiler = Webpack(webpackConfig);
const devServerOptions = { ...webpackConfig.devServer, open: true };
const server = new WebpackDevServer(devServerOptions, compiler);

const runServer = async () => {
  console.log(Starting server...);
  await server.start();
};

runServer();

然后使用以下命令运行服务器：

node server.js

startCallback(callback)

使用下面的代码告诉webpack-dev-server实例启动服务器，然后运行回调函数。

server.js

const Webpack = require(webpack);
const WebpackDevServer = require(webpack-dev-server);
const webpackConfig = require(./webpack.config.js);

const compiler = Webpack(webpackConfig);
const devServerOptions = { ...webpackConfig.devServer, open: true };
const server = new WebpackDevServer(devServerOptions, compiler);

server.startCallback(() => {
  console.log(Successfully started server on http://localhost:8080);
});

然后使用以下命令运行服务器：

node server.js

Stop

使用下面的代码告诉webpack-dev-server实例停止服务器。

server.js

const Webpack = require(webpack);
const WebpackDevServer = require(webpack-dev-server);
const webpackConfig = require(./webpack.config.js);

const compiler = Webpack(webpackConfig);
const devServerOptions = { ...webpackConfig.devServer, open: true };
const server = new WebpackDevServer(devServerOptions, compiler);

const runServer = async () => {
  console.log(Starting server...);
  await server.start();
};

const stopServer = async () => {
  console.log(Stopping server...);
  await server.stop();
};

runServer();

setTimeout(stopServer, 5000);

然后使用以下命令运行服务器：

node server.js

stopCallback(callback)

使用下面的代码告诉webpack-dev-server实例停止服务器，然后运行回调函数。

server.js

const Webpack = require(webpack);
const WebpackDevServer = require(webpack-dev-server);
const webpackConfig = require(./webpack.config.js);

const compiler = Webpack(webpackConfig);
const devServerOptions = { ...webpackConfig.devServer, open: true };
const server = new WebpackDevServer(devServerOptions, compiler);

server.startCallback(() => {
  console.log(Successfully started server on http://localhost:8080);
});

const stopServer = () =>
  server.stopCallback(() => {
    console.log(Server stopped.);
  });

setTimeout(stopServer, 5000);

然后使用以下命令运行服务器：

node server.js

internalIP(family: “v4” | “v6”)

同步返回内部IPv4/IPv6地址

server.js

const WebpackDevServer = require(webpack-dev-server);

const logInternalIPs = async () => {
  const localIPv4 = await WebpackDevServer.internalIP(v4);
  const localIPv6 = await WebpackDevServer.internalIP(v6);

  console.log(Local IPv4 address:, localIPv4);
  console.log(Local IPv6 address:, localIPv6);
};

logInternalIPs();

internalIPSync(family: “v4” | “v6”)

同步返回内部IPv4/IPv6地址

server.js

const WebpackDevServer = require(webpack-dev-server);

const localIPv4 = WebpackDevServer.internalIPSync(v4);
const localIPv6 = WebpackDevServer.internalIPSync(v6);

console.log(Local IPv4 address:, localIPv4);
console.log(Local IPv6 address:, localIPv6);
