A leave management solution is an application that allows an employee to request for leaves and a manager to accept or reject the leaves using Python Flask Application on Backend and Vue JS on Frontend. For the purpose of storing data, PostgreSQL database is used.

To get started with Leave-Management-Solution, follow the instructions below:-

Make sure you have the following prerequisites installed on your machine:

• Python (version 3.11.4)
• node (version 18.16.0)
• npm (version 9.5.1)
• PostgreSQL (version 15.3)
• pgAdmin 4 (version 7.3)

Clone the Leave-Management-Solution repository to your local machine using the following command:

git clone https://github.com/Anuj6264/Leave-Management-Solution.git 

Navigate to the cloned repository directory and install the project dependencies by running the following commands:

cd backend
pip3 install -r requirements.txt

For connecting to database, create a profile on pgAdmin 4 , creating username and password while installing it. Create a new Database in the dashboard. Now use these credentials in the backendApp.py file.

app.config['SQLALCHEMY_DATABASE_URI'] = 'postgresql://<your-username>:<your-password>@localhost:5432/<your-database-name>'

Save the file and run the backendApp.py file. This will connect the backend server with the PostgreSQL database and will create tables in this database.

cd frontend
cd frontend
npm init
npm install

Execute the following commands to run the application:

python backendApp.py

npm run serve

This will start backend and frontend applications at different ports. The frontend port will be possibly http://localhost:8080/ or http://localhost:8081/ and backend port should be http://127.0.0.1:5000.

Your app should be running by now, please check the port http://localhost:8080/ to see the application running!
