Deploy a Bun application on onesubnet

onesubnet runs your JavaScript/TypeScript applications via Bun (ultra-fast runtime, Node.js compatible). Deploy via Git.

1. Prepare the project

• A package.json with a start script, and @types/bun if using TypeScript.
• Listen on the port from the PORT variable:

const port = Number(process.env.PORT ?? 3000)
Bun.serve({ port, fetch: () => new Response("Hello from Bun") })

2. Deploy

1. Connect your Git repository in the panel.
2. Build command: bun install
3. Start command: bun run src/index.ts (or bun start).

3. Environment variables

In Settings → Environment (connection string, secrets…). Access via process.env or Bun.env.

4. Logs

Live console in the panel.
