Sans Server

Sans Server is a serverless framework that enables writing server-side code for a Connect-style request/response middleware pipeline without requiring an actual HTTP server. It is designed to simplify testing and development of middleware in a Node.js environment, with a current version of 2.0.3. Key differentiators include its focus on a Connect-compatible API and its ability to run middleware in isolation, reducing the need for server dependencies. Release cadence is low; the package has not been updated frequently in recent years.
