write-file-webpack-plugin

Forces webpack-dev-server program to write bundle files to the file system.

This plugin has no effect when webpack program is used instead of webpack-dev-server.

Webpack 5

This plugin is not needed with Webpack 5. You should instead use the writeToDisk option available in webpack-dev-server and in webpack-dev-middleware.

Install

npm install write-file-webpack-plugin --save-dev

API

 * @typedef {Object} options
 * @property {boolean} atomicReplace Atomically replace files content (i.e., to prevent programs like test watchers from seeing partial files) (default: true).
 * @property {boolean} exitOnErrors Stop writing files on webpack errors (default: true).
 * @property {boolean} force Forces the execution of the plugin regardless of being using `webpack-dev-server` or not (default: false).
 * @property {boolean} log Logs names of the files that are being written (or skipped because they have not changed) (default: true).
 * @property {RegExp} test A regular expression used to test if file should be written. When not present, all bundle will be written.
