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.
- Compatible with Go 1.19 and earlier versions.
- Requires Go 1.20 and later versions.
go install github.com/Buzzvil/recovergoroutine
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.
