CAP'N WEB: A NEW RPC SYSTEM FOR BROWSERS AND WEB SERVERS

Summary from the TLDR Web Dev newsletter

Cap'n Web is a new, open-source RPC system for JavaScript environments for facilitating communication between applications over a network. Unlike traditional RPC, Cap'n Web supports bidirectional calling, object-capability security, and promise pipelining, aiming for a developer experience similar to native JavaScript APIs. It makes setup easier, integrates with TypeScript, and uses human-readable JSON serialization.
