Webpack Virtual Modules is a plugin that allows for dynamical generation of in-memory virtual modules for JavaScript builds created with webpack. When virtual module is created all the parent virtual dirs that lead to the module filename are created too. This plugin supports watch mode meaning any write to a virtual module is seen by webpack as if a real file stored on disk has changed.
Use NPM or Yarn to install Webpack Virtual Modules as a development dependency:
# with NPM
npm install webpack-virtual-modules --save-dev
# with Yarn
yarn add webpack-virtual-modules --devYou can use Webpack Virtual Modules with webpack 5, 4 and 3. The examples below show the usage with webpack 5 or 4. If you want to use our plugin with webpack 3, check out a dedicated doc:
Require the plugin in the webpack configuration file, then create and add virtual modules in the plugins array in the
webpack configuration object:
var VirtualModulesPlugin = require('webpack-virtual-modules');
var virtualModules = new VirtualModulesPlugin({
'node_modules/module-foo.js': 'module.exports = { foo: "foo" };',
'node_modules/module-bar.js': 'module.exports = { bar: "bar" };'
});
module.exports = {
// ...
plugins: [
virtualModules
]
};You can now import your virtual modules anywhere in the application and use them:
var moduleFoo = require('module-foo');
// You can now use moduleFoo
console.log(moduleFoo.foo);You can generate virtual modules dynamically with Webpack Virtual Modules.
Here's an example of dynamic generation of a module. All you need to do is create new virtual modules using the plugin
and add them to the plugins array. After that, you need to add a webpack hook. For using hooks, consult webpack
compiler hook documentation.
var webpack = require('webpack');
var VirtualModulesPlugin = require('webpack-virtual-modules');
// Create an empty set of virtual modules
const virtualModules = new VirtualModulesPlugin();
var compiler = webpack({
// ...
plugins: [
virtualModules
]
});
compiler.hooks.compilation.tap('MyPlugin', function(compilation) {
virtualModules.writeModule('node_modules/module-foo.js', '');
});
compiler.watch();In other module or a Webpack plugin, you can write to the module module-foo whatever you need. After this write,
webpack will "see" that module-foo.js has changed and will restart compilation.
virtualModules.writeModule(
'node_modules/module-foo.js',
'module.exports = { foo: "foo" };'
