Simple Serverless Framework

I have been using the Serverless Framework to build AWS Lambda functions with Node and Express, but one of the issues that I faced was that a simple deployment was over 25MB because of all of the dependencies that Express requires. Express is a great framework, but it does so much more than I need.

In an attempt to reduce the size of my deployment I created a simple serverless web framework that looks remarkably like Express, but does not have any dependencies. The syntax is so similar, as a matter of fact, that I changed my import from Express to my new framework and I only required a single change: mapping paths like /user/:id to /user/{id}. I rebuilt my project using sls deploy and all of the code worked without modification.

This is still very limited to the features I am using, but it is built modular enough to add any features that you may need that are missing.

Currently I have support for:

• Parse an API Gateway event and convert it to an Express-like req
• Standard get, put, post, patch, and delete handlers
• A simple middleware framework that behaves similar to Express: (req, res, next) => {...}
• A res object that behaves similar to Express
• Advice (new): you can add BEFORE, AFTER, or AROUND advice that is executed after all middlewares, but before, after, or around the actual handler invocation; I needed this for performance measurements

Take a look at the unit tests for examples.
