externals-dependencies
Easily exclude dependencies in Webpack
Webpack allows you to define externals - modules that should not be bundled.
When bundling with Webpack for the backend - you usually don't want to bundle its node_modules
dependencies.
This library creates an externals function that ignores node_modules
when bundling in Webpack.
(Inspired by the great Backend apps with Webpack series and webpack-node-externals)
Quick usage
npm install externals-dependencies --save-dev
In your webpack.config.js
:
var externalsDep = ;...moduleexports = ... target: 'node' // in order to ignore built-in modules like path, fs, etc. node: console: true global: true process: true Buffer: true __filename: true __dirname: true setImmediate: true path: true externals: // in order to ignore all modules in node_modules folder ...;
And that's it. Any node modules in dependencies will no longer be bundled but will be left as require('module')
.
