Federation Hub Setup

This repository contains the code for setting up a federated marketplace using Go and PostgreSQL.

Prerequisites

• Go
• PostgreSQL

Getting Started

1. Clone the repository:

   git clone https://github.com/ADSP-Project/Federation-Hub.git

   cd Federation-Hub

2. Set up the PostgreSQL database:

   • Install PostgreSQL and connect:

     sudo apt install postgresql postgresql-contrib

     psql

   • Create a new database named 'shops':

     CREATE DATABASE shops;

   • Create a new user with appropriate privileges:

     CREATE USER your_username WITH PASSWORD 'your_password';

     GRANT ALL PRIVILEGES ON DATABASE shops TO your_username;

   • Connect to Postgres with your new user:

     psql -d shops -U your_username

   • Create a 'shops' table in the 'shops' database with columns 'id', 'name', and 'webhookURL':

     CREATE TABLE shops ( id SERIAL PRIMARY KEY, name VARCHAR(255), description VARCHAR(255), webhookURL VARCHAR(255), publicKey VARCHAR(1024) );

3. Configure environment variables:

   • Rename the .env.example file to .env.
   • Update the database credentials in the .env file to match your PostgreSQL setup.

4. Install dependencies:

   • Make sure to initialize go.mod to manage dependencies:

     go mod init github.com/ADSP-Project/Federation-Hub

   • Fetch and arrange them into newly generated go.mod:

     go mod tidy

   • Finally, install the required dependencies with the following command:

     go mod download

5. Run the main server:

   • Start the Go server using the following command:

     go run main.go

   • The server will start running on port 8000 by default.

6. Run the authentification server:

   • Start the authentification server using the following command:

     go run authServer.go

   • The server will start running on port 8081 by default.

7. Simulate a shop joining the federation:

   • To simulate a shop joining the federation, open a new terminal and run the following command:

     go run shop.go [port] [name]

     Replace [port] with the desired port number and [name] with the name of the shop.

     This will start a shop server that automatically joins the federation by sending a POST request to the federation server.

8. Access the federated marketplace:

   • You can now access the federated marketplace at http://localhost:8000.

9. Additional Notes:

   • You can run multiple instances of the shop server by providing different port numbers and shop names.
