I have built the app using the PERN stack:
| Frontend | Backend |
|---|---|
| React | Node |
| Redux | Express |
| Tailwind CSS | PostgreSQL |
| Passport.js |
To test the app, I have created test files using:
| Frontend | Backend |
|---|---|
| React Testing Library | Supertest |
| Jest | Jest |
Get an overview of the architecture of the app.
- Node.js version ≥ 16.18.0
- npm version ≥ 8.19.2
- PostgreSQL version ≥ 15
- Download a ZIP file of all the files of this app.
- Unzip it.
- Open the command line and go to the root directory of the app.
- Install all dependencies for the backend:
cd server/
npm i
- Install all dependencies for the frontend:
cd client/
npm i
- Create a PostgreSQL database using the SQL commands specified in database.sql.
- Change the database configuration in db.js to match your setup of PostgreSQL:
const pool = new Pool({
user: 'postgres',
password: 'password',
host: 'localhost',
port: 5432,
database: 'collnow'
});
Open the command line and go to the root directory of the app.
- Start the Node/Express server:
cd server/
node server.js
- Start the React server
cd client/
npm start
