L³ router

AWS CloudFront Lambda@Edge serverless application router.

Features

• Request/Response handling API.
• Routes and URI Resource support.
• Local/Globally scoped Middleware.
• Visual Studio Code integration.
• Open Source, MIT licensed, FREE.
• Lightweight (no dependencies).

How does it work?

In its most basic form the library provides helper methods that translate the CloudFront Lambda@Edge origin-request allowing you to handle response processing without the need to construct complex Lambda dependent responses.

To better visualize how L³ fits in the current AWS ecosystem the following high-level graph describes the HTTP Request/Response lifecycle and role of each AWS provided service.

Getting started

The easiest way to created an application, without the need to manually install this package, is to use the L³ Visual Studio Code extension. Doing so allows you to..

• Scaffold app sources and dependencies.
• Run it locally (in Remote - Containers)
• Test code changes in realtime.
• Deploy app sources to AWS.
• Generate JSDoc/Swagger documentation.

Build dependencies

If you're not using the L³ VS Code extension and want to run this package locally you must install the following dependencies:

• AWS SAM CLI
• Node.js

Manual installation

If you just looking to leverage the Request/Response handling API in your Lambda functions, install this package using NPM.

$ npm install @lambda-lambda-lambda/router
