[ElysiaJS](https://elysiajs.com/) is a web framework for building backend servers with Bun. [Bun](https://bun.com/) is a fast JavaScript runtime that serves as a bundler, test runner, and package manager.

You can use Render to host an ElysiaJS app. Render [supports Bun](/content/docs/language-support/index.html) natively.

## Deploying from the Render Dashboard

1. Fork [render-examples/elysiajs-hello-world](https://github.com/render-examples/elysiajs-hello-world) on GitHub.

2. Create a new **web service** on Render, and give Render permission to access your new repo.

3. Provide the following values during service creation:

| Setting | Value |
| --- | --- |
| **Language** | `Node` |
| **Build Command** | `bun install` |
| **Start Command** | `bun start` |

That's it! Your web service will be live at its `onrender.com` URL as soon as the deploy finishes.

## Deploying with a Blueprint (Infrastructure as Code)

1. Fork [render-examples/elysiajs-hello-world](https://github.com/render-examples/elysiajs-hello-world) on GitHub.

2. In the included `render.yaml` file, set the `repo` field to the URL of your fork. Commit this change.

3. Follow [these steps](/content/docs/infrastructure-as-code#setup/index.html) to create a new Blueprint using the `render.yaml` file.

That's it! Your web service will be live on your Render URL as soon as the deploy finishes.
