Function createMethodCircuitBreakerKey

kinetex — Feature-rich, universal TypeScript HTTP client.

Works in Node.js, Deno, Bun, browsers, Cloudflare Workers, Vercel Edge, and all WinterCG runtimes from a single zero-dependency codebase.

Example

// Node.js / Bun / Deno
import { kinetex } from "kinetex";
import { kinetex } from "jsr:@kinetexjs/kinetex";

const api = kinetex({ baseURL: "https://api.example.com/v1" });

// Fluent chain
const users = await api.GET("/users").bearer("token").json<User[]>();

// Standard send
const post = await api.post<Post>("/posts", JSON.stringify(body));

createMethodCircuitBreakerKey(req: KinetexRequest): string
Pre-built circuit-breaker key function that isolates breakers per HTTP method AND per origin — e.g. "GET:https://api.example.com".

Pass this to KinetexConfig.circuitBreakerKeyFn to prevent a stream of failing POST mutations from opening the breaker for safe GET reads:
```
import { kinetex, createMethodCircuitBreakerKey } from "kinetex";

const client = kinetex({
  circuitBreakerKeyFn: createMethodCircuitBreakerKey,
});
client.enableCircuitBreaker();
```
Parameters
- req: KinetexRequest
Returns string
A circuit breaker key in the form "METHOD:origin".
