Market Proxy

A Go-based market data fetcher agent with caching and an Nginx proxy for efficient data delivery.

Overview

This project consists of two main components:

1. Market Fetcher: A Go service that fetches and caches market data from CoinGecko and price updates from Binance.
2. Nginx Proxy: A reverse proxy that provides caching, ETag optimization, and compression for efficient delivery of market data.

Local Development

Prerequisites

• Docker and Docker Compose

Configuration

1. Create a config.yaml file in the market-fetcher directory:

coingecko_fetcher:
  update_interval: 10800  # seconds (3 hours)
  tokens_file: "coingecko_api_tokens.json"
  limit: 500  # number of tokens to fetch

2. (Optional) Create coingecko_api_tokens.json in the secrets directory for Pro API access:

{
  "api_tokens": ["your-api-key-here"]
}

If you don't provide this file, the service will use the public API without authentication.

Running Locally

Run the following command to start all services:

./start-local.sh

This will:

1. Create necessary configuration files if they don't exist
2. Build and start the following services:
   • market-fetcher: Fetches market data (port 8081)
   • market-proxy: Nginx proxy with caching (port 8080)
   • market-frontend: Test frontend application (port 3000)
3. Set up a Docker network for communication between services

Accessing the Services

• API Proxy: http://localhost:8080
• Frontend: http://localhost:3000

Subprojects
