How to deploy a NestJS app on your VPS

NestJS has become one of the most popular Node.js frameworks for building scalable server-side applications. With its modular architecture, dependency injection, and TypeScript support, it's the go-to choice for many backend developers. However, deploying a NestJS application on your own VPS (Virtual Private Server) can sometimes be challenging.

What is NestJS?

NestJS is a progressive Node.js framework built with TypeScript that enables developers to build efficient, reliable, and scalable server-side applications with features like:

• Dependency Injection system
• Modular architecture
• Express/Fastify compatibility
• WebSockets support
• Microservices support
• GraphQL integration
• TypeScript support
• Extensive CLI tooling

These features make NestJS an excellent choice for building modern backend applications, from simple APIs to complex enterprise applications.
