Build a Full-Stack Node.js App with CockroachDB Serverless

This article guides developers on how to create a full-stack Node.js app using CockroachDB Serverless, a cloud-based SQL database designed for scalability and resilience. The tutorial begins with setting up the development environment by installing Node.js and creating a new project folder. It then moves on to creating a simple Express.js server and connecting it to a CockroachDB Serverless cluster using Sequelize, an Object-Relational Mapping (ORM) library for Node.js. The app is designed to store and display contact information. The data is stored in a PostgreSQL database managed by CockroachDB Serverless. To handle user input, the tutorial uses Pug templates, which are server-side templating engines that allow developers to create dynamic HTML pages with embedded JavaScript code. The app also includes error handling and deployment on Heroku, a cloud platform for building, running, and managing applications. The final section of the article provides an overview of the complete code used in the tutorial and suggests ways to extend the application further.
