console

Overview ¶

Package console runs one-off commands inside the application context: a seed script, a data fix or a report that needs the same services as the app, without starting the HTTP server.

A command is any provider with a Name and a Run method:

type SeedCommand struct{ users *users.Service }

func (c *SeedCommand) Name() string { return "seed" }
func (c *SeedCommand) Run(ctx context.Context, args []string) error { ... }

and main hands its arguments over before it starts the server:

if len(os.Args) > 1 { // go run . seed
	os.Exit(console.Main(ctx, AppModule(cfg, log), os.Args[1:], dygo.WithLogger(log)))
}

dygo generate command writes both.
