User Interfaces

User Interface is designed and implemented on the front-end side. Further implementation stated on this repository

⚙️  How to Run the Program

Clone this repository from terminal with this command

$ git clone https://github.com/GoDillonAudris512/Classic-Cryptography-Simulator-Backend.git

Run the application on development server

1. Create a .env file inside the repository directory using .env.example file as the template. You can keep the variables blank. The server should automatically use port 8080 as the default port
2. Run the server using this following command

   go run main.go

If you do it correctly, the back-end development server should be running. You can also check the server by opening http://localhost:8080/api. To use back-end side functionalities, don't forget to also run the front-end side. Further explanation on how to run the front-end development server stated on this repository
