resilient-server

Dummy HTTP server fully compatible with the Resilient specification discovery protocol.

It provides a simple CRUD-like HTTP API to publish and store service servers URLs, with multiple application version based on semantic versioning. The stored servers are persisted as volatile data (in-memory). After a server restart is required data re-registering

It was designed to be used for testing, demo and development proposals with resilient based applications. For production environments, consider using Consul.

Additionally it implements full CORS support for direct browser consumption
