applog

Opinionated slog wiring for go-toolkit app lifecycles.

Install

go get gitea.auvem.com/go-toolkit/applog

Usage

lifecycle := app.NewLifecycle(applog.AppLogOpts{
    ConsoleOutput: os.Stderr,
    ConsoleLevel:  slog.LevelInfo,
    FileOutput:    "/var/log/myapp.log",
    FileLevel:     slog.LevelInfo,
}.Module())

Outputs

Sink	Format	Default level
Console (ConsoleOutput)	tint (human-readable)	Info
File (FileOutput)	JSON lines	Info

Teardown

On teardown the log file is closed and the lifecycle logger falls back to console-only (or discard). Logging via lifecycle.Logger() after teardown does not write to a closed file.
