@cfedk/cdk-node-lambda-wrapper v0.0.4

What is this thing?

A wrapper for node-based cdk-defined AWS Lambda handlers.

Instead of worrying about assets, import (1) your npm package handler code (2) this library package.

Usage

In your cdk application:

npm install --save your-lambda-handler @cfedk/cdk-node-lambda-wrapper pkg-dir

In your cdk code:

import * as pkgDir from 'pkg-dir';
import { NodeLambdaWrapper } from '@cfedk/cdk-node-lambda-wrapper';

const currentPackageDir = pkgDir.sync();
const myLambdaHandler = new NodeLambdaWrapper(this, 'Handler', {
    directory: currentPackageDir,
    packageName: 'your-lambda-handler'
}).handler;

Requirements

Your lambda handler package (your-lambda-handler above) must define a main in package.json, eg lib/index.js. This will be used as the entry point of the lambda.

The main file must export a function handler which will be run on invocation. Eg:

[...]
const server = serverlessExpress.createServer(app);

export const handler = (event: lambda.APIGatewayProxyEvent, context: lambda.Context) => {
    serverlessExpress.proxy(server, event, context);
}
