const ComponentKey = "component"

ComponentKey tags every record with the part of the system that wrote it.

This section is empty.

func Component(i do.Injector, component string) (*slog.Logger, error)

Component returns the logger tagged with the component writing through it. component also names the module in the error an absent logger produces.

func Module(opts ...Option) app.Module

Module provides a *slog.Logger and, unless WithoutDefault says otherwise, makes it the process default.

type Config struct {
	Level  slog.Level `config:"level"`
	Format string     `config:"format" validate:"required,oneof=text json"`
}

type Option func(*options)

func WithWriter(w io.Writer) Option

WithWriter sends records somewhere other than os.Stdout.

func WithoutDefault() Option

WithoutDefault leaves the package-level slog default alone, so a process can boot a logger without every other one in it changing underneath.
