HTTP Traffic Recording, Mocking, and Proxying for Connect

Connect-prism is a Node.js middleware designed to record, mock, and proxy HTTP traffic, primarily for front-end development and end-to-end testing of Single Page Applications (SPAs). It functions by integrating with the `connect` middleware framework, allowing developers to capture API responses, store them as JSON files, and then replay them locally, effectively caching backend interactions. The package supports four modes: 'record' (captures live responses), 'mock' (serves recorded responses), 'mock & record' (prioritizes mocks, records if not found), and 'proxy' (forwards requests to a target API). The current stable version, 1.0.21, was last published in early 2019, indicating an abandoned or minimally maintained status. Its key differentiators include its tight integration with `connect` servers for in-development mocking and its VCR-like approach to HTTP interaction capture, accelerating test suites and reducing reliance on live backend services during development. It decompresses gzipped/deflated responses for readable mock files.
