vi-fetch

Easiest way to mock fetch

Compatible with Vitest and Jest when using ESM flag or with transform for /node_modules/vi-fetch.

The main difference with fetch-mock or fetch-mock-jest is that they consider fetch just as a function call instead of function that calls API endpoints. vi-fetch provides matchers to test calls to endpoints instead of simply function calls.

For example, we consider an endpoint to be a part of URL until the first ?: query is an argument to an endpoint, just like body, - that's why we provide matchers like toHaveFetchedWithQuery and toHaveFetchedWithBody.
