bun-bagel is a mocking library specifically designed for Bun's fetch API. It enables developers to easily intercept fetch requests and provide custom mock responses, streamlining the development and testing process of Bun applications.
import { mock, clearMocks } from "bun-bagel";
// Register the mock for the example URL.
mock("https://example.com/api/users/*", { data: { name: "Foo" } });
// Make a fetch request to the mocked URL
const response = await fetch("https://example.com/api/users/123");
// Print the response body
console.log(await response.json());{ name: "Foo" }
- Lightweight and easy to use: Get started in minutes with a simple, intuitive API.
- Flexible and powerful: Handle a wide range of mocking scenarios with ease.
- Built for Bun: Seamlessly integrates with Bun's runtime for a smooth developer experience.
- Thoroughly tested: Comes with a comprehensive test suite to ensure reliability.
