Roadmap

Next

• @nestbun/ws: a WebSocket gateway adapter on Bun.serve({ websocket }), sharing the HTTP port, with Bun’s native pub/sub for rooms. Nest’s built-in ws and Socket.IO adapters attach to a Node server, so this has to be a separate package.
• Multipart uploads: @UploadedFile() / @UploadedFiles() backed by Request.formData(), with size and count limits.

Later

• Make --adapter bun the default in @nestbun/create once @nestbun/ws and multipart land.
• Backpressure on the streaming path (respect ReadableStream desiredSize).
• @nestjs/serve-static and @nestjs/graphql compatibility passes.
• HTTP/2 when Bun.serve exposes it.

Not planned

• Running on Node. The adapter is Bun-native on purpose.
• Full Express middleware emulation. Anything beyond the documented compatible subset is out of scope.
