isows

Isomorphic WebSocket implementation that works consistently across Node.js, Bun, Deno, and modern browsers. Version 1.0.7 provides a drop-in replacement for the native WebSocket API, using the 'ws' package on Node.js and the native implementation elsewhere. It is actively maintained by the wevm team (known for viem and wagmi). Unlike raw 'ws', isows provides a universal interface without bundler plugins. It is ESM-only and ships TypeScript definitions. Release cadence is infrequent, focused on stability.
