name: Deploy a Bun application on Render
|
|
---
|
|
|
|
[Render](https://render.com/) is a cloud platform that lets you flexibly build, deploy, and scale your apps.
|
|
|
|
It offers features like auto deploys from GitHub, a global CDN, private networks, automatic HTTPS setup, and managed PostgreSQL and Redis.
|
|
|
|
Render supports Bun natively. You can deploy Bun apps as web services, background workers, cron jobs, and more.
|
|
|
|
---
|
|
|
|
As an example, let's deploy a simple Express HTTP server to Render.
|
|
|
|
---
|
|
|
|
Create a new GitHub repo named `myapp`. Git clone it locally.
|
|
|
|
```sh
|
|
$ git clone git@github.com:my-github-username/myapp.git
|
|
$ cd myapp
|
|
```
|
|
|
|
---
|
|
|
|
Add the Express library.
|
|
|
|
```sh
|
|
$ bun add express
|
|
```
|
|
|
|
---
|
|
|
|
Define a simple server with Express:
|
|
|
|
```ts#app.ts
|
|
import express from "express";
|
|
|
|
const app = express();
|
|
const port = process.env.PORT || 3001;
|
|
|
|
app.get("/", (req, res) => {
|
|
res.send("Hello World!");
|
|
});
|
|
|
|
app.listen(port, () => {
|
|
console.log(`Listening on port ${port}...`);
|
|
});
|
|
```
|
|
|
|
---
|
|
|
|
Commit your changes and push to GitHub.
|
|
|
|
```sh
|
|
$ git add app.ts bun.lock package.json
|
|
$ git commit -m "Create simple Express app"
|
|
$ git push origin main
|
|
```
|
|
|
|
---
|
|
|
|
In your [Render Dashboard](https://dashboard.render.com/), click `New` > `Web Service` and connect your `myapp` repo.
|
|
|
|
---
|
|
|
|
In the Render UI, provide the following values during web service creation:
|
|
|
|
| | |
|
|
| ----------------- | ------------- |
|
|
| **Runtime** | `Node` |
|
|
| **Build Command** | `bun install` |
|
|
| **Start Command** | `bun app.ts` |
|
|
|
|
---
|
|
|
|
That's it! Your web service will be live at its assigned `onrender.com` URL as soon as the build finishes.
|
|
|
|
You can view the [deploy logs](https://docs.render.com/logging#logs-for-an-individual-deploy-or-job) for details. Refer to [Render's documentation](https://docs.render.com/deploys) for a complete overview of deploying on Render.
