Recovergoroutine

Summary

When operating a Go server, we typically use recover middleware. However, if using goroutines, a failure to handle a panic in a goroutine can result in server downtime. To address this, we can use recovergoroutine and check it through linting.

Install

go install github.com/Buzzvil/recovergoroutine

Usage

recovergoroutine -recover="" ./...

# -recover string
#         Custom recovery method name. You can use this option
#         when you want to call a method defined in a struct or
#         use CustomRecover declared in an external package.

Check out the test cases for validation examples.
