Deploying a Netlify application with TypeScript and CockroachDB involves setting up a scalable, serverless database system that's both cost-effective and straightforward to implement. The process begins with creating free accounts on Netlify and CockroachDB, followed by deploying a sample application using TypeScript. The application uses CockroachDB, a cloud-native distributed SQL database, integrated via Prisma for database management. After obtaining the sample application code from GitHub, users set up their databases by modifying environment variables and utilizing Prisma to synchronize the database schema. The deployment includes local testing with Netlify's CLI and concludes with a full public deployment, all of which can be achieved without incurring any costs. This approach demonstrates how modern tools can facilitate the development and deployment of scalable applications efficiently and inexpensively.
