Cloudflare Workers and Containers now support inbound TCP connections and gRPC
Key points
- Workers runtime now includes a connect() handler for inbound TCP sockets.
- Full-duplex, bi-directional gRPC is supported from Cloudflare Containers.
- Workers can serve and call gRPC APIs using gRPC-web.
- The new features are available in private beta.
Expanded Connectivity for Cloudflare Workers
Cloudflare has announced new capabilities for its Workers platform, specifically enabling inbound TCP connections. This expansion allows Workers to directly accept incoming TCP sockets, which can be routed to other Workers or Durable Objects. The new connect() handler in the Workers runtime facilitates this functionality.
Enhanced gRPC Support
The update also introduces enhanced support for gRPC applications on Cloudflare. Developers can now run full-duplex, bi-directional gRPC servers within Cloudflare Containers, forwarding sockets from Workers to these containers. Additionally, Workers can serve unary and server-streaming gRPC APIs and call gRPC servers, with automatic conversion of requests to and from gRPC-web.
Implications for Real-time Applications
These new features are particularly relevant for applications requiring low-latency communication, such as real-time assistants, AI-powered dictation, and other voice interfaces. gRPC, built on HTTP/2 and TCP, is a common framework for such infrastructure, and its deeper integration into Cloudflare's ecosystem aims to simplify the development and deployment of these services.
Availability
The new inbound TCP connection and gRPC features are currently available in a private beta. Interested developers can sign up to access these capabilities.
