## What it is
An Angular library that intercepts Http and HttpClient requests and redirects them to an in-memory data store, emulating a REST API with CRUD operations. It is intended for demos, prototypes, and tests rather than production use, and the code has since moved into the angular/angular repo.

## Use cases
- simulate a REST backend for Angular demo apps without running a server
- prototype CRUD apps quickly before building a real API
- share live Angular examples on Plunker or CodePen
- unit test apps that read and write data with a resettable data store
- run end-to-end tests in CI without touching a real database
- stub out collections not yet implemented on a dev server

## When to choose
- building Angular demos, tutorials, or prototypes that need fake CRUD persistence
- writing Angular unit or e2e tests that need consistent in-memory HTTP responses
- sharing runnable Angular examples in browser coding environments

## When to avoid
- production applications needing a real backend
- projects needing faithful emulation of complex real-world web APIs
- teams needing active maintenance or stable guarantees - the repo is archived and always experimental

## Facets
- artifact type: library
- maturity: abandoned
- function: mocking, http-client, testing, e2e-testing
