alpha-lambda
Tiny wrapper that ensures that AWS Lambda function's callback is always called. In other words, from your handler you can return value, promise, throw exception, and this library will wrap your code into a promise while calling appropriate lambda-required callback. Your handler is composed of middleware, similar to Express or Koa.
Installation
$ npm install alpha-lambda
Usage
If you do things in a usual way, you'll construct your lambda handlers similar to this:
const handler = { try const result = ; if result ; else ; catch err ; }
With alpha-lambda
you should not worry about top-level error handling, so you can write your handlers just like this:
const alphaLambda = ; moduleexportshandler = ;
Error Handling
If you need custom error handling, you can do this by adding error handler as one of the first middleware, like:
const alphaLambda = ;const co = ; moduleexportshandler =
Middleware
Use these middleware to extend functionality.
