Setting up a PostgreSQL and Node.js Project

This guide will help you set up a Node.js Backend project with a PostgreSQL database.

Prerequisites

• Node.js: Ensure you have Node.js installed on your system.
• PostgreSQL: Install PostgreSQL on your machine.
• pg (Node.js client): This is a popular PostgreSQL client for Node.js. We'll install it using npm.

Project Setup

1. Clone the repository and navigate to the backend:

   git clone [https://github.com/arifuzzaman31/manushtech_task.git](https://github.com/arifuzzaman31/manushtech_task.git)
   cd manushtech_task/backend/

2. Initialize a Node.js Project:

   npm install
   

Configure the Database Connection

You'll need to create a file to store your database connection string. It is common to use a .env file for this, and the dotenv package to load it.

1. Create a Database:

   • Open the PostgreSQL command-line interface (e.g., psql) or a GUI tool like pgAdmin.

   • Create a new database. For example:

     CREATE DATABASE manushtech_pgdb;

2. Create a .env file:

   nano .env
   

3. Add the Connection String to .env:

   DATABASE_URL="postgresql://user:password@localhost:5432/manushtech_pgdb"
   

   • Important: Replace the values with your actual PostgreSQL credentials.

Explanation of the Connection String

The connection string you provided, DATABASE_URL="postgresql://postgres:7575@localhost:5432/manushtech_pgdb", follows this general format:

postgresql://[user]:[password]@[host]:[port]/[database]

4. Then, run the following commands:

npm install
npx prisma migrate dev --name initial
npx prisma generate
npm run seed
npm run dev

Frontend Setup

1. install npm:

cd manushtech_task/frontend/
npm install
or
npm install -f
npm run dev

2. Login Creadentials:

email: abir@manush.tech
password: adminpassword
