Package Exports

aws-cdk-webpack-lambda-function
aws-cdk-webpack-lambda-function/lib/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (aws-cdk-webpack-lambda-function) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

aws-cdk-webpack-lambda-function

forked from @aws-cdk/aws-lambda-nodejs

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

Quick Start

install using yarn:

npm i -D aws-cdk-webpack-lambda-function aws-cdk-lib webpack@5 webpack-cli

cdk	aws-cdk-webpack-lambda-function
v1	0.6.0
v2	1.0.0

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",
});

Options

entry: string (required)

Path to the entry file (JavaScript or TypeScript).

config: string (required)

Path to webpack config file.

handler: string

The name of the exported handler in the entry file.

default: "handler"

runtime: lambda.Runtime

The runtime environment. Only runtimes of the Node.js family are supported.
