Method AddModule

c.go:210–230

AddModule adds a module to the core. A Module is a group of functionality. It must provide some runnable stuff: http handlers, grpc handlers, cron jobs, one-time command, etc. Optionally if the module embeds di.In, its fields will be injected by DI container. The semantics of injection follows the

(module interface{})

// Note that the module added in this way will not retain any original field
// values, i.e. the module will only contain fields populated by DI container.
func (c *C) AddModule(module interface{}) {
	t := reflect.TypeOf(module)
	if t.Kind() == reflect.Ptr && dig.IsIn(t.Elem()) {
		err := di.IntoPopulator(c.di).Populate(module)
		if err != nil {
			panic(err)
		}
		c.Container.AddModule(module)
		return
	}
	if dig.IsIn(t) {
		copy := reflect.New(t)
		err := di.IntoPopulator(c.di).Populate(copy.Interface())
		if err != nil {
			panic(err)
		}
		c.Container.AddModule(copy.Elem().Interface())
		return
	}
	c.Container.AddModule(module)
