About This Application
This application uses PostgreSQL as its database and Next.js API routes to handle data operations, making it a full-fledged CRUD (Create, Read, Update, Delete) application.
PostgreSQL
PostgreSQL is a powerful, open-source object-relational database system. It has a strong reputation for reliability, feature robustness, and performance. In this application, PostgreSQL is used to store and manage all the data.
Next.js API Routes
Next.js provides a powerful way to create API routes. These routes can be used to handle various data operations such as creating, reading, updating, and deleting records in the PostgreSQL database. The API routes are defined in the /pages/api
directory.
Example API Route
Here is an example of a simple API route to fetch all records from a PostgreSQL database:
// pages/api/records.js
import { Pool } from 'pg';
const pool = new Pool({
user: 'yourusername',
host: 'localhost',
database: 'yourdatabase',
password: 'yourpassword',
port: 5432,
});
export default async (req, res) => {
try {
const result = await pool.query('SELECT * FROM records');
res.status(200).json(result.rows);
} catch (error) {
res.status(500).json({ error: 'Internal Server Error' });
}
};
This route connects to the PostgreSQL database, fetches all records from the records
table, and returns them as a JSON response.
CRUD Operations
The application supports the following CRUD operations:
- Create: Add new records to the database.
- Read: Fetch and display records from the database.
- Update: Modify existing records in the database.
- Delete: Remove records from the database.
Each of these operations is handled by a corresponding API route in the /pages/api
directory.
