Building explicit data-flow graphs in TypeScript: Introducing Transferum

Short summary

Transferum is an open-source TypeScript library for building graph-based data-flow models using capability-driven nodes called Transfers. Unlike traditional reactive frameworks, each node explicitly declares capabilities (push, pull, filter, buffer) that shape both compile-time types and runtime binding strategies. The library enforces strict invariants around protocol-oriented design, undefined suppression, and unified error handling.

• •Transferum uses capability flags (isPushable, isPullable, etc.) to drive both TypeScript interfaces and runtime connections
• •linkTransfers() auto-resolves binding strategies based on capability combinations, avoiding class-based checks
• •Built-in async transfers support concurrency limits, buffering, and graceful overflow handling
