Node.js Express.js, PostgreSQL, Docker & CRUD Operations. 🌟

This project is designed to guide you through the essentials of setting up a Node.js server, performing CRUD operations, and interacting with a PostgreSQL database. Follow along to create a scalable and containerized application! 🖥️🐘

What's Inside 🚀:

• Express.js Server: Node.js server using Express.js.
• PostgreSQL Integration: Connect the server to a PostgreSQL database and perform CRUD operations.
• Docker Setup: Use Docker to containerize the application for consistent and scalable deployments.
• API Endpoints: Implement various API endpoints to interact with the database.

Get Started with Node.js & PostgreSQL App

API Endpoints - From Basic Operations to Advanced Queries 🔄

The project includes various API endpoints to manage data in the PostgreSQL database. With these endpoints.

What's Included 📋:

• GET /create: 🏗️ Create the schools table in the database.
• POST /: ➕ Add a new entry to the schools table.
• GET /: 📥 Fetch all entries from the schools table.
• PUT /: ✏️ Update an entry by it's ID from the schools table.
• DELETE /:id: 🗑️ Delete an entry by its ID from the schools table.

Docker Configuration - Simplify Your Development Environment 🐳

The Docker setup ensures that your application runs consistently across different environments. By using Docker Compose, you can easily manage both your Node.js application and PostgreSQL database.

Docker Compose Configuration 🛠️

This is the Dockerfile Compose configuration to manage both your database and application in one place.

FROM node:16

WORKDIR /app

COPY package*.json ./

RUN npm install

COPY . .

EXPOSE 3000

CMD ["npm", "start"]

## Docker Compose Configuration yaml

version: "3.7"

services:
  db:
    image: postgres:12
    environment:
      POSTGRES_USER: root
      POSTGRES_PASSWORD: password
      POSTGRES_DB: pgdb
    ports:
      - "5432:5432"

  app:
    image: umukoro-node-app
    ports:
      - "4000:3000"
    depends_on:
      - db

Getting Started 💻

1. Clone the Repository

git clone <repository-url>
cd <repository-directory>

2. Build and Start Containers

docker compose up --build

3. Access the Application Open your browser and navigate to http://localhost:4000 to start interacting with your application.

Troubleshooting 🔧

• Port Binding Issues: Ensure no other process is using port 3000 or adjust the port mapping in docker-compose.yml.

• Database Connection: Verify that the database service is running and accessible.
