@weftjs/adapters

The ports, implemented: Node HTTP, channels, stores, sessions, flags, leases and a worker pool.

Part of weft, a TypeScript fullstack framework that negotiates the wire form of a piece of UI per request. Eleven of the fourteen ports are bound by the front door with no configuration at all.

npm install @weftjs/adapters

What it is

The kernel imports nothing but the WinterTC Minimum Common Web API, so everything platform-shaped lives here. Fourteen ports are declared and fourteen are implemented.

A port that is not bound refuses by name and never approximates. A declared rate limit with no limiter is E_NO_RATE_LIMIT, not unlimited. countingLimits is a fixed window and says so — a sliding one needs a store that can count atomically, and StorePort deliberately has a lease rather than a counter.

A store on an edge key-value namespace refuses lease outright. A lease that is not atomic is a stampede guard that does not guard and a replay guard that reports every nonce fresh, which is the one place in this framework where an approximation would be a security bug. sharedLeases(store, { dir }) agrees across every process on a machine; redisLeases(store, { url }) across every instance of a deployment; neither makes the cache shared.
