| Run Bun as a daemon with PM2 |
PM2 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:
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.
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
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.
