Webpack Runtime for Serverless

A plugin to use Webpack to run and build your Serverless function.

This plugin is heavily inspired by serverless-runtime-babel and serverless-webpack-plugin.

Features

• Runs locally and deploys functions bundled with Webpack
• Compile all your dependencies in a single JS file
• Use any loader you want, Babel with ES2015 and stage-0 presets is already bundled with this plugin

Install

Note: Serverless v0.5.0 or higher is required.

• Install via npm in the root of your Serverless Project: npm install serverless-runtime-webpack --save-dev
• In the plugins array in your s-project.json add "serverless-runtime-webpack"
• Install the loaders you will use in your Webpack configuration npm install babel-loader --save-dev
• All done!

Usage

All you need is to set runtime property of s-function.json to webpack.

From scratch you can:

• serverless project create as usual
• serverless function create myfunc and select webpack when asked for a runtime
• serverless function run myfun done!

Scaffold

You can use serverless function create as usual — it will prompt you for a runtime unless you add the -r webpack flag.

Examples

GitHub stargazers example returns amount of starts for a GitHub repo.

Copy the stars folder in a Serverless project configured with this plugin as described in the Install section above; then run serverless function run stars.
