| /** |
| Create a type that represents either the value or the value wrapped in `PromiseLike`. |
| |
| Use-cases: |
| - A function accepts a callback that may either return a value synchronously or may return a promised value. |
| - This type could be the return type of `Promise#then()`, `Promise#catch()`, and `Promise#finally()` callbacks. |
| |
| Please upvote [this issue](https://github.com/microsoft/TypeScript/issues/31394) if you want to have this type as a built-in in TypeScript. |
| |
| @example |
| ``` |
| import {Promisable} from 'type-fest'; |
| |
| async function logger(getLogEntry: () => Promisable<string>): Promise<void> { |
| const entry = await getLogEntry(); |
| console.log(entry); |
| } |
| |
| logger(() => 'foo'); |
| logger(() => Promise.resolve('bar')); |
| ``` |
| */ |
| export type Promisable<T> = T | PromiseLike<T>; |
