Lambda Express

What?

An express-like framework for use with AWS Lambda functions that supports both API Gateway and Application Load Balancer integrations with Lambda.

The entire library is written in TypeScript so you get great autocomplete if you're using VS Code or similar. It's also very well tested, so you can rest assured that it will do what you need, and regressions between versions will be rare.

Why?

You shouldn't have to think about how API Gateway or Application Load Balancer send you request events, or how you need to respond to them with your responses. There are a lot of little intricacies, especially if you are using API Gateway for some of your APIs and Application Load Balancer for others (see this writeup for the differences).

If you're writing APIs, you've probably already written Express apps, so keeping things familiar will accelerate your development, allowing you to focus on your business logic.

Usage

Here's a simple example to get you up and running quickly (assumes your execution environment is Node 12.x):

npm i @silvermine/lambda-express

npm i -D aws-lambda

1import { Application, Response, Request } from '@silvermine/lambda-express';
2import { RequestEvent } from '@silvermine/lambda-express/dist/types/request-response-types';
3import { NextCallback } from '@silvermine/lambda-express/dist/types/interfaces';
4import { Context, Callback } from 'aws-lambda';
5
6const app = new Application();
7
8app.all('/*', (_request: Request, response: Response, next: NextCallback) => {
9   response.set('Access-Control-Allow-Origin', '*');
10   next();
11});
12
13app.options('/*', (_request: Request, response: Response) => {
14   response.set('Access-Control-Allow-Methods', 'OPTIONS,GET')
15      .set('Access-Control-Allow-Credentials', 'false');
16   response.send('');
17});
18
19app.get('/my-endpoint', async (request: Request, response: Response) => {
20   response.send('Hello world!');
21});
22
23export const handler = (event: RequestEvent, context: Context, callback: Callback): void => {
24   app.run(event, context, callback);
25};
26
27export default handler;

At this point you should be able to compile, bundle, and deploy this Lambda. Assuming you have configured APIGW or ALB to forward traffic to your Lambda, you will now have a very basic working API!
