CelsianJS Vercel Adapter

Run CelsianJS apps on Vercel — both the Node.js serverless runtime and the Edge runtime.

Part of the CelsianJS monorepo. See the root README for full framework docs.

Installation

npm install @celsian/core @celsian/adapter-vercel

Usage

Node serverless runtime:

// api/index.ts
import { createApp } from '@celsian/core';
import { createVercelHandler } from '@celsian/adapter-vercel';

const app = createApp();
app.get('/api/hello', (req, reply) => reply.json({ ok: true }));

export default createVercelHandler(app);

Edge runtime (no Node built-ins; bundles cleanly for workerd-style edges):

import { createVercelEdgeHandler } from '@celsian/adapter-vercel';
export const config = { runtime: 'edge' };
export default createVercelEdgeHandler(app);

For scheduled work, createVercelCronHandler(app, process.env.CRON_SECRET) validates Vercel Cron requests (timing-safe) and runs the matching app.cron() jobs. app.task() workers need a durable queue (@celsian/queue-redis). See the root deployment docs.
