Function ConcatInjectable

Creates an Injectable factory function without dependencies that appends a Service to an existing array of Services of the same type. Useful for dynamically expanding service collections without altering original service tokens or factories.

Note: Prefer using container.append('token', () => value) or container.appendValue('token', value) instead.

Example

// Prefer the inline form:
const container = Container
  .providesValue("values", [1])
  .append("values", () => 2);

// ConcatInjectable is the lower-level primitive:
const container2 = Container
  .providesValue("values", [1])
  .provides(ConcatInjectable("values", () => 2));

// Both result in container.get("values") === [1, 2]
Copy

Creates an Injectable factory function with dependencies that appends a Service to an existing array of Services of the same type. This variant supports services that require other services to be instantiated, allowing for more complex setups.

Example

const container = Container
  .providesValue("two", 2)
  .providesValue("values", [1]) // Initially provide an array with one value
  .provides(ConcatInjectable("values", ["two"] as const, (two: number) => two)); // Append another value to the array

const result = container.get("values"); // [1, 2]
