About The Project

git-to-feed is a production-ready, event-driven Go microservice designed under Clean Architecture and Package-by-Feature principles. It listens to GitHub repository Webhooks (Pull Requests and Releases), enriches event contexts, formats payloads using LLMs (Google Gemini AI) guided by curated Few-Shot Examples, and notifies an interactive Discord Bot for Human-in-the-Loop approval before live publication to LinkedIn.

Architecture & Package-by-Feature Layout

The codebase strictly decouples business domain logic from infrastructure, storage, and transport layers.

Getting Started

Follow these steps to set up and run git-to-feed.

Prerequisites

• Docker & Docker Compose (Recommended for production & local execution)
• Go 1.22+ (Optional for local Go CLI development)

Environment Configuration

Create a .env file in the root directory (refer to .env.example):

PORT=":8080"
GITHUB_WEBHOOK_SECRET="your-github-webhook-secret"
LINKEDIN_ACCESS_TOKEN="your-linkedin-access-token"
LINKEDIN_AUTHOR_URN="urn:li:person:your-author-urn"
DATABASE_URL="postgres://postgres.[PROJECT-REF]:[PASSWORD]@aws-0-[REGION].pooler.supabase.com:5432/postgres?sslmode=require"
DISCORD_BOT_TOKEN="your-discord-bot-token"
DISCORD_CHANNEL_RELEASES_ID="your-discord-channel-releases-id"
DISCORD_CHANNEL_FEATURES_ID="your-discord-channel-features-id"
DISCORD_CHANNEL_AUDIT_ID="your-discord-channel-audit-id"
DISCORD_CHANNEL_ID="your-discord-channel-id"
GEMINI_API_KEY="your-google-gemini-api-key"
GEMINI_MODEL_NAME="gemini-3.5-flash-lite"

Docker Containerization (Recommended)

Run the application stack using Docker Compose:

docker-compose up --build -d

Or build and run using Docker CLI directly:

docker build -t git-to-feed:latest .
docker run -d -p 8080:8080 --env-file .env git-to-feed:latest

Local Development

For building and testing directly with the Go toolchain:

# Download Go module dependencies
go mod download

# Run the API server locally
go run cmd/api/main.go

# Run unit tests & static analysis
go vet ./...
go test -v ./...
