Developers from Wasmer presented the JavaScript runtime environment WinterJS 1.0. This system supports React Server components and work with the Cloudflare API – the authors claim that WinterJS is the fastest runtime environment to date. The environment code is written in JavaScript and Rust.
WinterJS was announced in October 2023, and the project now boasts support for processing basic HTTP requests and the JavaScript event loop. The runtime can be compiled entirely into WebAssembly, which also makes it the first to support full compatibility with Wasmer Edge.
The key features and advantages of WinterJS include the following:
processing 150 thousand requests per second – this makes the environment the fastest available; Cloudflare API compatible; support for Next.js, Hono, Astro, SvelteKit web frameworks, React Server, Nuxt, Gatsby and Remix.run components.
The WinterJS runtime code was published on GitHub, and at the same time, the project developers disclosed the results of tests and benchmarks.
