Small package to allow you to invoke your Go AWS lambda locally.
This might be useful for:
- You want to run an integration test, maybe in conjunction with LocalStack?
- Unit testing is probably better in most cases
- You want to validate your CI has built a valid
linuxbinary of your application before deploying
I wrote a blog post about it here https://djhworld.github.io/post/2018/01/27/running-go-aws-lambda-functions-locally/
go get -u github.com/djhworld/go-lambda-invoke/golambdainvoke
Run the example lambda toupperlambda.go on port 8001
_LAMBDA_SERVER_PORT=8001 go run ./toupperlambda.go
Then use this library in tests or wherever you need it, by calling
response, err := golambdainvoke.Run(8001, "payload")
payload can be any structure that can be encoded by the
encoding/json package. Your lambda function will need to use this structure in its type signature.
