Build an API from scratch using MikroORM, Node.js, and Express.js

The tutorial explores the use of MikroORM, a TypeScript ORM for Node.js, by guiding users through the process of building a RESTful API for a blog application using technologies such as Express.js, PostgreSQL, and Node.js. It provides a comprehensive step-by-step approach to setting up the project, defining entities, running migrations, and creating controllers for CRUD operations on blog posts. The tutorial is designed for developers with some JavaScript knowledge and emphasizes the use of MikroORM's features like the Data Mapper and Identity Map patterns. It includes practical examples and snippets to illustrate how to create, read, update, and delete posts, and it highlights the importance of tools like Postman for testing API endpoints. The guide also mentions additional considerations for building real-world applications, such as authentication and improved error handling, and provides a GitHub repository for reference.
