Always explicitly declare all Makefile targets that don't create files as `.PHONY`. This prevents conflicts with potential files of the same name, makes build intentions clear, and increases reliability in CI/CD pipelines.
Always explicitly declare all Makefile targets that don’t create files as .PHONY. This prevents conflicts with potential files of the same name, makes build intentions clear, and increases reliability in CI/CD pipelines.
For better readability and maintenance, place the .PHONY declaration directly above the corresponding target:
.PHONY: deps
deps:
go get -d -v github.com/dustin/go-broadcast/...
.PHONY: build
build: deps
go build -o realtime-chat main.go rooms.go template.go
Rather than grouping all .PHONY declarations at the end or beginning of the Makefile, this pattern makes the relationship between declarations and targets obvious at a glance, reducing the chance of forgetting to update declarations when adding new targets.
