yakbak is a Node.js library that records and replays HTTP responses, inspired by Ruby's VCR. It proxies requests to a target host, saving responses to disk as tape files that can be replayed in tests or via a standalone CLI server.

Use cases

• record http responses for tests
• replay http interactions in node tests
• mock external api responses in integration tests
• vcr-style http recording for javascript
• proxy and record api calls during development
• play back a recorded http response on a local server

When to choose

• you want VCR-style record/replay of real HTTP traffic in Node.js tests
• you need recorded responses stored as plain files in version control
• you want a simple handler that plugs into http.Server or express middleware

When to avoid

• you need request/response matching beyond simple hashing or flexible stubbing
• you prefer snapshot libraries like nock or Polly.js with richer APIs
• the project is unmaintained and you need active support for modern Node versions
