serverless-bundle

An extension of the serverless-webpack plugin. This plugin bundles your Node.js Lambda functions with sensible defaults so you don't have to maintain your own Webpack configs.

• Caching for faster builds
• Use ES6 import/export
• Source map support for proper error messages

And all this works without having to install Webpack, Babel, etc. or manage any of their configs. Simply add serverless-bundle to your app and you are done!

You can read more about this over on Serverless Stack.

Getting Started

Install the serverless-bundle plugin using:

$ npm install --save-dev serverless-bundle

Then add it to your serverless.yml.

plugins:
  - serverless-bundle

To run your tests using the same Babel config used in the plugin add the following to your package.json:

"scripts": {
  "test": "serverless-bundle test"
}

Usage

Once installed and added to your serverless.yml, serverless-bundle will automatically package your functions using Webpack when you run the various serverless commands.

Options

You can configure the following through your serverless.yml.

custom:
  bundle:
    sourcemaps: true      # Enable source maps
    caching: true         # Enable Webpack caching
    stats: false          # Don't print out any Webpack output
    linting: true         # Enable linting as a part of the build process
    copyFiles:            # Copy any additional files to the generated package
      - from: 'public/*'    # Where the files are currently
        to: './'            # Where in the package should they go

Advanced Options

• Customizing Babel and Webpack configs

  This plugin does not support customizing the Babel and Webpack configs, since serverless-webpack does a pretty good job with that. However, if you think the default config is missing some key features, feel free to open an issue about it.

Updating Options

This plugin enables Webpack caching to speed up builds. Meaning that you'll need to clear the cache when you make a config change. So if you add an file, or change any other option; you'll need to do the following to see your changes take effect.

$ rm -rf node_modules/.cache
