JSPM – webpack-virtual-modules@0.1.5

Package Exports

webpack-virtual-modules

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (webpack-virtual-modules) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Webpack Virtual Modules

Webpack Plugin that allows dynamical generation of in-memory virtual modules.

Installation

npm install --save-dev webpack-virtual-modules

Usage

Static virtual modules generation

Sample Webpack config:

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
    ]
};

Somewhere in the source code:

var moduleFoo = require('module-foo');
// Outputs 'foo'
console.log(moduleFoo.foo);

Dynamic virtual modules generation

var webpack = require("webpack");
var VirtualModulesPlugin = require("webpack-virtual-modules");

var virtualModules = new VirtualModulesPlugin();

var compiler = webpack({
    // ...
    plugins: [
      virtualModules
    ]
});

compiler.plugin('watch', function(callback) {
  virtualModules.writeModule('node_modules/module-foo.js', '');
  callback();
});

compiler.watch();

// Later in some other code, perhaps in other Webpack plugin:
virtualModules.writeModule('node_modules/module-foo.js', 
    'module.exports = { foo: "foo" };');

// After this writre the webpack will "see" that module-foo.js
// has been changed and restarts compilation
