TypeORM Models and Validation 👨‍💻 Develop an App from Scratch (Part 3)

In this video I start working on the server which is a NodeJS application written in TypeScript. I made the decision to use PostgreSQL as the DBMS and TypeORM because of its excellent TypeScript syntax. In the video, I define models for the User, Budget, CategoryBudget, Category and Transaction entities. I implement validation with the class-validator library that allows validating a class with TypeScript decorators using validator.js in the background. For the user model I implement password hashing with salt using bcrypt that works seamlessly in the model on save/update and the user model includes a method to validate the user password.
