HTTP

Thin wrapper around fetch with AbortController timeout, JSON sugar and ergonomic helpers.

fetchAbortControllertimeout

request

const res = await F.http.request("/api/user", {
  method: "POST",
  json: { name: "Ada" },   // auto JSON.stringify + Content-Type
  headers: { "X-Token": "…" },
  timeout: 5000            // aborts via AbortController
});
if (!res.ok) throw new Error(`HTTP ${res.status}`);

On non-2xx, Flash throws Error with error.status and error.response (the Response).

Helpers

const user = await F.http.json("/api/user/42");
const text = await F.http.text("/api/readme");
const blob = await F.http.blob("/api/file");
const buf  = await F.http.arrayBuffer("/api/file");

const res1 = await F.http.get("/api/data", { timeout: 3000 });
await F.http.post("/api/user", JSON.stringify({ name: "Ada" }));
await F.http.put("/api/user/1", body);
await F.http.patch("/api/user/1", body);
await F.http.delete("/api/user/1");

ESM-only import: import { http } from "flash.js/http" — tree-shakable if you only need HTTP.

Error handling

try {
  const data = await F.http.json("/api/user/1", { timeout: 4000 });
} catch (e) {
  if (e.status === 404) F.toast("Not found","error");
  else if (e.name === "AbortError") F.toast("Timeout","warn");
  else F.toast(e.message,"error");
}
