I enjoy programming in Go, but recently I was doing some frontend programming.
NPM has all these watch command that automatically rerun tasks when files are updated.
Neat, has Go something like that without installing some binary?
No, but Go's CLI does work nice with the Unix philosophy.
watch go test ./...
Every five seconds your tests of packages that have been changed will be tested.
So no wasted resources, no extra tooling required!
Just a need little trick.
