Elysia on Vercel

Elysia on Vercel is a deployment starter for an Elysia TypeScript API: dependencies install with Bun, the app is previewed locally through the Vercel CLI at http://localhost:3000/, and it ships to Vercel's cloud with a single deploy command.

What is Elysia on Vercel?

Elysia on Vercel is a small starter template for building an HTTP API with the Elysia framework and hosting it on Vercel. You write route handlers in TypeScript, install dependencies with Bun using bun i, run the app locally with the Vercel CLI using vc dev, view it at http://localhost:3000/, and publish it with vc deploy. The repository carries the tagline "Develop. Preview. Ship." and is indexed under topics including cli, cloud, command, hosting, jamstack, ship and vercel.

What makes it stand out?

• Bun-first dependency install — bun i handles package installation, so the workflow assumes the Bun runtime and its package manager instead of npm or yarn.
• Vercel CLI local preview — vc dev starts the development server, and the running app answers on http://localhost:3000/.
• Single-command deployment — vc deploy publishes the project to Vercel's hosting platform, with no additional build script documented in the README.
• Elysia API layer — the application is an Elysia app, the Bun-oriented TypeScript framework used to declare HTTP routes and return responses.
• Cloud and Jamstack hosting target — the repository topics describe a command-line, cloud hosting, Jamstack deployment flow around Vercel.
• Two-tool toolchain — the documented setup lists only Bun and the Vercel CLI; no database, auth provider, styling system or CMS step appears on the page, which keeps onboarding to two commands.

Who should use it?

• Bun and Elysia developers — anyone already writing Elysia route handlers who needs a working local-plus-cloud loop without wiring build config by hand.
• API prototypers — developers who want a reachable server on localhost:3000 within two terminal commands before committing to any infrastructure.
• Vercel CLI users — teams already using vc commands who want an API project that fits the same preview and deploy habits as their other Vercel projects.

What can you do with Elysia on Vercel?

• Ship a JSON API quickly: define Elysia routes, run vc dev, and test responses at http://localhost:3000/ before any deployment exists.
• Preview before shipping: use the Vercel CLI development server to verify behavior locally, then push the same project to Vercel with vc deploy.
• Move an Elysia service to managed hosting: take an existing Elysia app and place it behind Vercel's hosting and CLI workflow instead of running your own server.

How does it work?

1. bun i — install the project's dependencies with Bun.
2. vc dev — start the local development server through the Vercel CLI.
3. Open http://localhost:3000/ to reach the running app.
4. vc deploy — publish the project to Vercel.

FAQ

What is Elysia on Vercel used for?

It is a starter for deploying an Elysia API on Vercel. You install packages with Bun, develop against a local server on port 3000 through the Vercel CLI, and publish with vc deploy, so the template covers the local development and deployment loop rather than application logic.

Which port does the local dev server use?

The README points you to http://localhost:3000/ after running vc dev, so port 3000 is the address the app listens on during local development. No alternative port is mentioned on the page.

How do I deploy the app to Vercel?

Run vc deploy from the project root. Deployment goes through the Vercel CLI, which is also the tool used for local development, so the same command-line interface covers both the preview and the production push.

Do I need Bun, or can I use npm?

The documented install step is bun i, which uses the Bun package manager. Bun is also the runtime Elysia targets. The page shows no npm, yarn or pnpm equivalents, so following the README as written assumes Bun is installed locally.

Does the template include a database or frontend?

No database, CMS, authentication provider or frontend framework is listed on the page. The starter describes only an Elysia API plus the two commands needed to run it locally and deploy it, leaving persistence and any UI to be added separately.
