Class: InjectionToken<T>

Defined in: src/wirestate-core/binding/binding-tokens.ts:34

Typed reference token for dependencies stored in a container.

Remarks

Use an InjectionToken<T> when a dependency needs a named, collision-free runtime key that carries the resolved TypeScript type. It works well for configuration, external objects, interfaces, and service contracts that should be resolved through an explicit key. The token is identified by object reference, not by its description.

Example

import { Container, InjectionToken, Injectable, inject } from "@wirestate/core";

interface RuntimeConfig {
  readonly apiUrl: string;
}

const RUNTIME_CONFIG = new InjectionToken<RuntimeConfig>("RUNTIME_CONFIG");

const container = new Container({
  bindings: [{ token: RUNTIME_CONFIG, value: { apiUrl: "https://api.example.com" } }],
});

@Injectable()
class ApiClient {
  public constructor(private readonly config = inject(RUNTIME_CONFIG)) {}
}

Type Parameters

Type Parameter
T

Constructors

Constructor

new InjectionToken<T>(description: string | symbol): InjectionToken<T>;

Defined in: src/wirestate-core/binding/binding-tokens.ts:46

Creates an injection token with a human-readable description.

Parameters

Parameter	Type	Description
description	string | symbol	Description used in diagnostics.

Returns

InjectionToken<T>

Methods

toString()

toString(): string;

Defined in: src/wirestate-core/binding/binding-tokens.ts:53

Returns a diagnostic label for this token.

Returns

string

Human-readable token label.

Properties

_type?

protected readonly optional _type?: T;

Defined in: src/wirestate-core/binding/binding-tokens.ts:39

Phantom field that ties the token to its value type. It exists so InjectionToken<A> is not assignable to InjectionToken<B>.
