WinterJS is a high-performance JavaScript server that executes Service Worker scripts following the WinterCG specification, built on SpiderMonkey and hyper. It can handle up to 100,000 requests per second and runs natively or via Wasmer, but is now deprecated in favor of Edge.js.
Use cases
- run service worker scripts as an http server
- host wintercg-compatible javascript edge functions
- serve fetch handlers with a fast js runtime
- run javascript servers sandboxed with wasmer
- benchmark high-throughput js request handling
When to choose
- you need a WinterCG-compliant service worker server today and can accept an unmaintained project
- you want extremely high request throughput on modest hardware
- you already use Wasmer and want sandboxed JS execution
When to avoid
- starting a new project - it is deprecated in favor of Edge.js
- you need full Node.js API compatibility
- you require long-term support or active maintenance
