mock-requests
JSON →Mocks XMLHttpRequest and fetch requests with static or dynamic responses without changing source code. Current stable version 1.4.3. Release cadence appears low (latest 2022). Differentiators: no source code modification needed, supports both XHR and fetch, dynamic responses based on payload/query parameters, delay simulation, and Webpack plugin for production-like mocking. Unlike alternatives like fetch-mock or nock, it intercepts at the browser level and works with both APIs seamlessly.
