dependency-packer-webpack-plugin v2.0.2
A Webpack plugin that automatically packs dependencies for entry points individually for Node projects.
This does a similar job to Serverless
Webpack, but instead
of solely inspecting the project\'s package.json
(and being dependent
on the Serverless project) - this plugin utilizes the Webpack
compiler\'s module hooks to determine exactly what dependencies are
required.
This works perfectly with aws-cdk (and presumably similar projects), enabling direct asset references to the bundle:
const fun = new lambda.Function(this, 'lambdaFunction', {
functionName: 'lambdaFunction',
runtime: lambda.Runtime.NodeJS810,
handler: 'fun.handler', // <-
code: lambda.Code.asset('.webpack/fun'), // <-
});
Usage
First, install the plugin: [npm/yarn] install
dependency-packer-webpack-plugin
, then reference and add it to your
Webpack config:
const DependencyPackerPlugin = require('dependency-packer-webpack-plugin').DependencyPackerPlugin;
module.exports = [{
...
entry: {
fun: 'fun.js',
},
output: {
filename: '[name].js',
path: '.webpack/<entry-name>',
}
...
plugins: [
new DependencyPackerPlugin({ // Must be initialized per bundle
blacklist: [/aws-sdk/], // Optional
packageManager: 'npm' // Optional
}),
],
}]; // One config per entry point to initiate multiple compilers
For multiple entry points, each bundle must be output to its own directory to avoid conflicts during installation of dependencies. To do so, it\'s recommended to export a list of configs, one for each entry point.
For practical examples see examples/

Development
Use NPM/Yarn links to easily integrate the plugin in your project to test special cases that are not covered by the unit tests.
[npm run/yarn] build
[npm/yarn] link
cd <project-that-uses-this-plugin>
[npm/yarn] link dependency-packer-webpack-plugin
For convenience, the TypeScript config adds specific path prefixes to
indicate relative paths of the src
, dist
and test
directories:
@
: src/#
: dist/$
: test/
