Nest.js and Prisma in 1 week

Day 1-2: Understanding Nest.js Fundamentals

1. Introduction to Nest.js
   • What is Nest.js? Understand its architecture (Modules, Controllers, Services).
   • Watch official Nest.js videos or read docs to get a broad overview.
   • Set up a basic Nest.js project using the Nest CLI (npm i -g @nestjs/cli).
   • Create your first module, controller, and service to build a simple REST API.
2. Core Concepts
   • Learn about Dependency Injection, Providers, and Middleware.
   • Practice creating multiple modules (e.g., Users module) and learn how they communicate.
3. Routing and Controllers
   • Get comfortable with creating routes in controllers.
   • Practice with basic HTTP methods (GET, POST, PUT, DELETE).

Day 3-4: Prisma Fundamentals and Integrating with Nest.js

1. Introduction to Prisma
   • Install Prisma (npm i prisma --save-dev).
   • Initialize Prisma in your Nest.js project (npx prisma init).
   • Learn the Prisma schema syntax: model definitions, relations, and types.
2. Database Setup
   • Set up a database (PostgreSQL, MySQL, SQLite, etc.) locally or use a cloud database.
   • Define some basic models (e.g., User, Post).
   • Run migrations to create the database tables (npx prisma migrate dev).
3. Integrating Prisma with Nest.js
   • Install @prisma/client and create a PrismaService to handle the database operations.
   • Inject the PrismaService into your Nest.js controllers or services.
   • Practice querying the database using Prisma (CRUD operations).

Day 5: Advanced Nest.js and Prisma Topics

1. Validation and Error Handling
   • Use Pipes for input validation (class-validator, class-transformer).
   • Implement error handling using filters and exception classes.
2. Authentication & Authorization
   • Set up JWT-based authentication using @nestjs/passport and @nestjs/jwt.
   • Implement guards for role-based authorization.
3. Prisma Advanced Queries
   • Learn to handle complex relations, transactions, and raw SQL queries with Prisma.
   • Practice pagination, filtering, and sorting.

Day 6: Building a Full CRUD API

• Put everything together by building a complete CRUD API (e.g., Blog API with Users and Posts).
• Create routes for authentication, and restrict some routes based on user roles.
• Use Postman or Insomnia to test your API.

Day 7: Deployment and Final Touches

1. Dockerize your Nest.js app (optional but great for scalability).
2. Deploy to a platform like Heroku or DigitalOcean.
3. Add Swagger to auto-generate API documentation (@nestjs/swagger).
