#API overview

Everything below is available with no imports — Fairyfly injects these globals into every script. Bare specifiers still resolve through node_modules for packages (see Packages).

#Globals

#Timer handles

setTimeout / setInterval return a Timeout object (pass it to clearTimeout / clearInterval, or call its methods):

const t = setTimeout(() => console.log("later"), 5000);
t.unref();      // don't hold the process open
t.refresh();    // restart the countdown
t.hasRef();     // boolean
t.ref();        // hold the process again

#Static helpers you'll use constantly

Response.json({ ok: true });              // Response with JSON content-type
Response.redirect("/login");              // 302 status only — no Location header
URL.parse("not a url");                   // null instead of throwing
new URL("/a/b", "https://x.example");     // base resolution
crypto.randomUUID();                      // v4 UUID
Database.open("app.db");                  // SQLite
