How Do You Run Webpack from a JavaScript file?

Question

As we all know, you can run Webpack from the command line using the CLI by running,

webpack

Which reads the file webpack.config.js and compiles your files accordingly.

Is it possible to do this same thing from within a file? In other words, is it possible to run Webpack without using the CLI?

Answer 1

Yes.

https://webpack.js.org/api/node/

const webpack = require("webpack");

webpack({
  // Configuration Object
}, (err, stats) => {
  if (err || stats.hasErrors()) {
    // Handle errors here
  }
  // Done processing
});
