Function: Autoload()

Autoload<ClassConstructor>(): ClassDecorator<ClassConstructor>

Let the container register the class on first use: when the class is requested (by getObject(TheClass) or @Inject(TheClass)) and is not registered, it is registered, then resolved, instead of failing. A singleton is registered in the root container (shared by the whole application), a scoped class in the nearest scope (shared within the request), a transient class in the requesting container. The registration has no options: the @Configurable properties take the options given to getObject(), else their initializers or their schema defaults. The mark is not inherited by subclasses.

Type Parameters

ClassConstructor

ClassConstructor extends typeof BaseObject

Returns

ClassDecorator<ClassConstructor>

The class decorator.

Example

import {Component, Provider} from 'lakutata'
import {Autoload, Inject, Scoped} from 'lakutata/decorator/di'

//Not declared in the application: registered the first time it is injected
@Autoload()
@Scoped()
class RequestClock extends Provider {
    public readonly startedAt: number = Date.now()
}

class Reports extends Component {
    @Inject(RequestClock)
    protected readonly clock!: RequestClock

    public elapsed(): number {
        return Date.now() - this.clock.startedAt
    }
}
