Interface: Tag()<T, N>

Defined in: src/types.ts:58

A tag, made by createTag: a name for an extension point. Calling it builds the key of a service under the tag (route('orders') is 'orders:route'); collect(tag) gives a factory every service registered under it, as an array of T.

Example

export const route = createTag('route').of<Route>();

c.addSingleton(route('orders'), (): Route => ordersRoute); // the key 'orders:route'
c.addSingleton('router', (routes) => new Router(routes), [collect(route)]); // routes: Route[]

Type Parameters

T

T = unknown

N

N extends string = string

Tag<K>(name): `${K}:${N}` & TaggedKey<T, `${K}:${N}`>

Defined in: src/types.ts:63

The key of a service under this tag: name:<tag>. It carries the tag's type, so addSingleton() checks the service registered under it.
