+name: Run Bun as a daemon with PM2
+---
+
+[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
+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.
+
+```javascript
+module.exports = {
+  name: "app", // Name of your application
+  script: "index.ts", // Entry point of your application
+  interpreter: "~/.bun/bin/bun", // Path to the Bun interpreter
+};
+```
+
+---
+
+After saving the file, you can start your application with PM2
+
+```bash
+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.
