Class: Http

Fluent facade for outgoing (server-to-server) HTTP requests. Static verb methods (Http.get, Http.post, …) return a PendingRequest that can be awaited directly or chained (.json(), .text()). Prefix a request with configuration (Http.withHeaders, Http.withToken, Http.timeout, Http.retry) to apply it before the verb.

The fake/assert* helpers intercept requests in tests so no real network traffic occurs.

Example

// GET with a custom header, retry, and timeout
const users = await Http
  .withHeaders({ "X-Trace": "abc" })
  .retry(3, 200)      // up to 3 attempts, 200ms apart
  .timeout(5000)      // abort after 5s
  .get("https://api.example.com/users")
  .json();

// POST a JSON body with a bearer token
const created = await Http
  .withToken("secret")
  .post("https://api.example.com/users", { name: "Alice" })
  .json();

// Testing — intercept requests
Http.fake([{ url: "https://api.example.com/*", body: { ok: true } }]);
await Http.get("https://api.example.com/users");
Http.assertSent((req) => req.url.includes("/users"));
Http.resetFakes();
