Go-Rich

This project is an example of how to use RabbitMQ and Go to process exchange rates.

Overview

The project consists of three main parts:

1. Server (API): A Go API that receives requests to fetch exchange rates.

2. Sender (Sender): Sends exchange rate responses to a message broker.

3. Worker (Worker): A Go worker that consumes messages from a message broker, fetches exchange rates, and sends the results back to the API.

Requirements

• Go
• RabbitMQ / Amazon SQS
• Docker

Configuration

Before running the project, you need to create a free account at CurrencyFreaks to obtain an API access key.

Create a .env file in the api folder with the following content:

  API_KEY=YOUR_API_KEY

Running the Project

1. Start RabbitMQ (In case you're using it over AmazonSQS):

   # Latest RabbitMQ 3.12
   docker run -it --rm --name rabbitmq -p 5672:5672 -p 15672:15672 rabbitmq:3.12-management
   

2. Start the Worker:

   go run ./workers/worker.go
   

3. Start the Server:

   go run ./api/server.go
   

Make a GET request to the API at the following URL:

http://localhost:8080/latest?currency=USD

Replace USD with the desired currency.
