API: startCallback(callback)

While it's recommended to run webpack-dev-server via the CLI, you may also choose to start a server via the API.

This example demonstrates using startCallback(callback) method. It instructs webpack-dev-server instance to start the server and then run the callback function.

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

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

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

Use the following command to run this example:

node server.js

What Should Happen

1. Open http://localhost:8080/ in your preferred browser.
2. You should see the text on the page itself change to read Success!.
3. You should see Successfully started server on http://localhost:8080 in the terminal output.
