fasthttplambda

This package allows you to use the fasthttp (and fasthttprouter) package to create your own service for AWS Lambda.

It has been updated to use aws/aws-lambda-go instead of the eawsy/aws-lambda-go-shim it previously used.

Usage example

See example/example.go

Key components

  • A fasthttplambda.Handle method, which you should call;
  • A fasthttplambda.Router (of type *fasthttp.Router) which you should set beforehand;
    • You can use this Router to define your routes / methods;
  • You can use this Router for local development as well, so you don't have to deploy every time.

How does it work

Currently, it works by catching the request body and headers from the AWS Lambda call, and using them to create an in-memory fasthttp.Request to call to the router we defined.

Possible optimizations

It's be nice to reference the memory already allocated within the event, instead of copying it into our own Request. However, since the fasthttp.RequestCtx is not an interface, there's little chance to get it working without forking the fasthttp package.

Contributing

Any contributions are welcome. This is just a proof-of-concept at this stage. Bug reports / PRs are welcome.
