Crafting a RESTful API with NestJS, Docker, Swagger, and Prisma by creating a delightful recipe management system to implement CRUD (Create, Read, Update, Delete) operations for managing recipes.

To build this application, I will be leveraging the power of the following tools:

• NestJS: A progressive Node.js framework for building efficient, reliable, and scalable server-side applications.
• Prisma: An open-source database toolkit that makes it easy to reason about your data and how you interact with it.
• PostgreSQL: A powerful, open source object-relational database system.
• Docker: An open platform for developing, shipping, and running applications. Docker enables you to separate your applications from your infrastructure so you can deliver software quickly.
• Swagger: A tool for designing, building, and documenting RESTful APIs.
• TypeScript: A statically typed superset of JavaScript that adds optional types, classes, and modules to the language.

Each of these technologies plays a crucial role in creating a robust, scalable, and maintainable application.

• Node.js - Runtime Environment
• Docker - For containerizing database
• Visual Studio Code - Code Editor
• PostgreSQL - Database
• NestJS - Node.js Framework

NestJS is a progressive Node.js framework that comes with a plethora of advantages, including a powerful Command Line Interface (CLI). This CLI simplifies the process of creating a new NestJS application, making it easy to start a new project anytime, anywhere.

One of the key benefits of NestJS is its rich set of built-in functionalities that significantly streamline the development process, making your life as a developer much easier.

To store our recipes REST API, we'll use a PostgreSQL database. Docker will help us containerize this database ensuring a smooth setup and execution, regardless of the environment.

The configuration of the project(docker-compose.yml):

version: '3.8'
services:
  postgres:
    image: postgres:13.5
    restart: always
    environment:
      - POSTGRES_USER=recipe
      - POSTGRES_PASSWORD=RecipePassword
    volumes:
      - postgres:/var/lib/postgresql/data
    ports:
      - '5444:5432'
volumes:
  postgres:

Here's a quick breakdown of this configuration:

• image: postgres:13.5: Specifies the Docker image for the PostgreSQL database.
• restart: always: Ensures the container restarts if it stops.
• environment: Sets the username and password for the database.
• volumes: Mounts a volume to persist database data, even if the container is stopped or removed.
• ports: Exposes port 5432 on both the host machine and the container for database access.

Prisma is an open-source database toolkit that makes it easy to reason about your data and how you interact with it.

Prisma is a powerful tool that offers a wide range of features, including:

• Database Migrations: Prisma makes it easy to evolve your database schema over time, without losing any data.
• Database Seeding: Prisma allows you to seed your database with test data.
• Database Access: Prisma provides a powerful API for accessing your database.
• Database Schema Management: Prisma allows you to define your database schema using the Prisma Schema Language.
• Database Querying: Prisma provides a powerful API for querying your database.
• Database Relationships: Prisma allows you to define relationships between your database tables.
