在 Node.js 脚本中触发 webpack 无命令行构建

Question

Is there some way to trigger a webpack build without using the command line webpack build task in a node.js script? I know I can use the exec function to execute a command line task, but I'm looking for a way that doesn't involve the command line at all.

I'm looking for something that works like

import webpack from "webpack";
await webpack.build(...);

You can use the webpack Node API ( https://webpack.js.org/api/node/ ).

Create a webpack instance, as specified in the docs, like so:

import webpack from 'webpack';

const compiler = webpack({}, (err, stats) => {
  if (err || stats.hasErrors()) {
    // ...
  }
  // Done processing
});

Then, use the run method on compiler to, as the docs say, "kickstart all compilation work".

compiler.run(() => console.log('Done'));
