deploy_function
Deploy serverless Node 22 functions to a project. Bundles npm dependencies at deploy time and supports cron schedule triggers.
Instructions
Deploy a serverless function (Node 22) to a project. Handler signature: export default async (req: Request) => Response. The function can import { db, adminDb, auth, email, ai } from '@run402/functions' — auto-bundled by the platform. Additional npm packages are bundled at deploy time when listed in deps (bare names resolve to latest; pinned/range specs are honored verbatim; @run402/functions and run402-functions rejected; max 30 entries; native binaries rejected). For schedule/email background triggers, prefer a unified deploy manifest with functions.replace.<name>.triggers[] so every trigger creates a durable function run. The response includes runtime_version (the bundled @run402/functions version — surface as 'Functions runtime version', never bare 'runtime'), deps_resolved (map of dep name → installed concrete version), and an optional top-level warnings array (sibling to the function record).
