Getting Started

To get started with this project, follow these steps:

Prerequisites

Before you can run the front-end and back-end servers, you need to have the following software installed on your machine:

• Node.js
• npm
• Python 3
• pip
• MySQL

Installing

To install the project dependencies, run the following command in URL_Shortener/frontend/url-shortener/:

npm install

This will install all the necessary dependencies for the front-end server.

To install the back-end dependencies, run the following command in URL_Shortener/backend/:

pip install -r requirements.txt

This will install all the necessary dependencies for the back-end server.

Configuration

Configuration of Front-end

Before you can start the servers, you need to set the API URL and port in the .env file. Follow these steps to set up the API URL and port:

1. Open the .env file in the URL_Shortener/frontend/url-shortener/ directory.

2. Update the REACT_APP_API_URL and REACT_APP_API_PORT fields with the correct API URL and port. For example:

REACT_APP_API_URL=127.0.0.1
REACT_APP_API_PORT=8000

Replace 127.0.0.1 with the IP address or domain name of your server, and 8000 with the port number that the back-end server will be running on.

Setting up the Database

To set up the database, follow these steps:

1. Run the following command to start up the MySQL server:

mysqld.exe --console

2. Log in to MySQL using the command line or a MySQL client.

3. Create a new database for the URL Shortener application:

CREATE DATABASE url_shortener;

4. Import the data.sql file to create the necessary tables and data:

USE url_shortener;
SOURCE URL_Shortener/backend/data.sql;

This will create the necessary tables and data for the application.

Configuration of Back-end

Before you can start the back-end server, you need to set up the database connection in database.py. Follow these steps to set up the database connection:

1. Open the database.py file in the URL_Shortener/backend/ directory.

2. Update the SQLALCHEMY_DATABASE_URL field with the correct database connection information. For example:

SQLALCHEMY_DATABASE_URL = "mysql+pymysql://root:<password>@localhost:3306/url_mapping_db"

Replace <password> with the password for the root user.

3. Save the database.py file.

Starting the Servers

To start the front-end server, run the following command in URL_Shortener/frontend/url-shortener/ of the project:

npm start

This will start the front-end server on port 3000.

To start the back-end server, run the following command in URL_Shortener/backend/:

uvicorn main:app --host 0.0.0.0 --reload

This will start the back-end server on port 8000.

Accessing the Application

Once the servers are running, you can access the application by opening a web browser and navigating to http://localhost:3000. This will display the front-end of the application.

The back-end API can be accessed by sending HTTP requests to http://localhost:8000. The API documentation can be found in the http://localhost:8000/docs.
