mockjs-fetch

Extends Mock.js to support intercepting fetch-based AJAX requests, enabling seamless mocking of fetch API calls alongside existing XMLHttpRequest mocks. Current stable version is 2.0.0, released with a breaking change in import syntax (named export instead of default). Release cadence is low, with only a few versions. Key differentiators: integrates with Mock.js for full mock syntax support, or can be used standalone for simple fetch-only mocking without Mock.js dependency. Important: must be disabled in production to avoid runtime side effects.
