golang uber fx
What it does
- pkg.go.dev/go.uber.org/fx
- uber-go.github.io/fx
- github.com/uber-go/fx
- advanced.md — Supply/Replace/Decorate, optional deps, custom event logging, manual lifecycle, full Quick Reference
- testing.md — fxtest patterns, fx.Replace, fx.Populate, isolated lifecycle tests, CI graph validation
- → See samber/cc-skills-golang@golang-uber-dig skill for the underlying container, dig.In/dig.Out, and DI without lifecycle
- → See samber/cc-skills-golang@golang-dependency-injection skill for DI concepts and library comparison
Requirements & configuration
- fx re-exports dig's dig.In / dig.Out as fx.In / fx.Out. Use them when a constructor has 4+ dependencies, or when you need name/group/optional tags.
- 2. Use lifecycle hooks instead of init() or goroutines launched from constructors — Start/Stop ordering depends on graph topology, but init() goroutines do not, which leads to races and leaks.

golang-uber-fx FAQ
What does the golang-uber-fx skill do?
Golang application framework using uber-go/fx — fx.New, fx.Provide, fx.Invoke, fx.Module, fx.Lifecycle hooks, fx.Annotate (name/group/As), fx.Decorate, fx.Supply, fx.Replace, fx.WithLogger, and signal-aware Run(). Apply when using or adopting uber-go/fx, when the codebase imports `go.uber.org/fx`, or when wiring services with fx.New. For raw DI without lifecycle, see `samber/cc-skills-golang@golang-uber-dig` skill. pkg.go.dev/go.uber.org/fx uber-go.github.io/fx
