env-runner

env-runner is a generic environment runner for JavaScript applications, abstracting away the complexities of various runtime environments. It enables developers to run server applications across Node.js worker threads, child processes, Bun, Deno, Cloudflare Workers (via Miniflare), Vercel, Netlify, or even in-process. The package provides essential features like hot-reloading for development, WebSocket proxying, and a bidirectional messaging system between the main process and the runner environment. Currently at version 0.1.7, it is actively developed with rapid minor releases focusing on enhancements and new runner integrations, offering a unified API for deploying serverless functions or local servers across diverse JavaScript ecosystems. Its key differentiator is providing a consistent interface regardless of the underlying runtime.
