Type Alias Promisable<T>

Promisable: T | Promise<T>

Represents a value that may or may not be wrapped in a Promise.

Convenient for APIs that accept both synchronous and asynchronous return values, avoiding the need for callers to wrap synchronous results.

Type Parameters

T
The underlying value type.

Example

async function process(input: Promisable<string>): Promise<number> {
    const value = await input;
    return value.length;
}

process('hello');                  // ✓ OK — synchronous
process(Promise.resolve('hello')); // ✓ OK — asynchronous
