[PM2](https://pm2.keymetrics.io/) is a popular process manager that manages and runs your applications as daemons (background processes).
|
||
|
||
It offers features like process monitoring, automatic restarts, and easy scaling. Using a process manager is common when deploying a Bun application on a cloud-hosted virtual private server (VPS), as it:
|
||
|
||
- Keeps your Node.js application running continuously.
|
||
- Ensure high availability and reliability of your application.
|
||
- Monitor and manage multiple processes with ease.
|
||
- Simplify the deployment process.

You can use PM2 with Bun in two ways: as a CLI option or in a configuration file.
|
||
|
||
### With `--interpreter`
|
||
|
||
To start your application with PM2 and Bun as the interpreter, open your terminal and run the following command:
|
||
|
||
```bash terminal icon="terminal"
|
||
pm2 start --interpreter ~/.bun/bin/bun index.ts
|
||
```
|
||
|
||
---
|
||
|
||
### With a configuration file
|
||
|
||
Alternatively, you can create a PM2 configuration file. Create a file named `pm2.config.js` in your project directory and add the following content.
|
||
|
||
```js pm2.config.js icon="file-code"
|
||
module.exports = {
|
||
name: "app", // Name of your application
|
||
script: "index.ts", // Entry point of your application
|
||
interpreter: "bun", // Bun interpreter
|
||
env: {
|
||
PATH: `${process.env.HOME}/.bun/bin:${process.env.PATH}`, // Add "~/.bun/bin/bun" to PATH
|
||
},
|
||
};
|
||
```
|
||
|
||
---
|
||
|
||
After saving the file, you can start your application with PM2
|
||
|
||
```bash terminal icon="terminal"
|
||
pm2 start pm2.config.js
|
||
```
|
||
|
||
---
|
||
|
||
That’s it! Your JavaScript/TypeScript web server is now running as a daemon with PM2 using Bun as the interpreter.
