aws-cdk-webpack-lambda-function

This library provides constructs for Node.js Lambda function bundled using webpack.

Quick Start

install using yarn:

yarn add -D aws-cdk-webpack-lambda-function @aws-cdk/core @aws-cdk/aws-lambda webpack webpack-cli
# npm i -D aws-cdk-webpack-lambda-function @aws-cdk/core @aws-cdk/aws-lambda webpack webpack-cli

add webpack.config.js:

module.exports = {
  mode: 'production', // production or development
  target: 'node',
  externals: [/^aws-sdk(\/.+)?$/], // important!!!
  devtool: 'source-map', // if needed
  optimization: { minimize: false }, // if needed
  // for TypeScript
  module: {
    rules: [
      {
        test: /\.ts$/,
        use: {
          loader: 'ts-loader',
          options: {
            configFile: 'your/path/to/tsconfig.json', // if needed
            // colors: true,
            // logInfoToStdOut: true,
            // logLevel: 'INFO',
            transpileOnly: true,
          },
        },
        exclude: /node_modules/,
      },
     ],
  },
  resolve: {
    extensions: ['.js', '.ts'],
  },
}

(Optional) add tsconfig.json for lambda

{
  "extends": "../ ... /tsconfig.json",
  "compilerOptions": {
    "importHelpers": false,
    "target": "ES2018",
    "noEmit": false
  }
}

your cdk source code:

import { WebpackFunction } from 'aws-cdk-webpack-lambda-function'

new WebpackFunction(this, 'YourFunction', {
  entry: 'your/path/to/function.ts',
  config: 'your/path/to/webpack.config.js',
})
