V-Insight — Monitoring SaaS

V-Insight is a Docker-based monitoring platform with a focus on reliability and observability. It includes an API backend, background worker jobs, and a SvelteKit frontend with a CORS-free API proxy.

• Backend: Go, Gin (port 8080)
• Worker: Go (port 8081)
• Frontend: SvelteKit (port 3000)
• Database: PostgreSQL 15
• Shared: Go module for domain entities and repositories

---

Quick overview

V-Insight performs automated health checks (HTTP/HTTPS) and SSL expiry monitoring, evaluates alert rules, creates incidents, and notifies configured channels (webhook, Discord, email-ready).

It supports user isolation via user_id on all main tables and enforces user-scoped queries consistently in handlers and repositories.

Architecture Refactoring: The project now uses a Go Workspace (go.work) with a shared module to centralize domain logic and repositories, reducing duplication between Backend and Worker services.

Key features

• HTTP/HTTPS health checks, uptime and response time tracking
• SSL certificate expiry checks
• Flexible alert rules (down, slow_response, ssl_expiry)
• Incident lifecycle with automatic resolution
• Notification channels: webhook, Discord, (email-ready)
• Docker-first developer workflow and automatic DB migrations

Quick start (development)

git clone https://github.com/eovipmak/v-insight.git
cd v-insight
cp .env.example .env
make up

Or without make:

docker compose up -d

• Backend: http://localhost:8080
• Frontend: http://localhost:3000
• Swagger API: http://localhost:8080/swagger/

Migrations run automatically on startup.

For developers and contributors

This project uses Go Workspaces.

• Setup Workspace: go work sync
• Shared Module: shared/ contains entities and repositories.
• Backend: backend/ contains API handlers and services.
• Worker: worker/ contains background jobs.

Tests:

• Shared: cd shared && go test ./...
• Backend: cd backend && go test ./...
• Worker: cd worker && go test ./...
• Frontend: cd frontend && npm run check (TypeScript), npx playwright test (E2E)

Tips:

• Do not commit .env files to the repository – use environment configurations for production.
• Use make convenience commands (make up, make logs, make rebuild, make migrate-up, etc.)

For AI agents and automations

To make it easier for LLMs, bots, or automation agents to work in this repo, see docs/ai_agents.md. Key notes:

• API proxy: frontend/src/routes/api/[...path]/+server.ts — do NOT add CORS middleware.
• User Isolation: Always include and verify user_id context when querying or modifying user-scoped resources.
• Migrations: Located in backend/migrations/ — use make migrate-create then edit up/down SQL files; run make migrate-up.
• Tests: Backend/Worker use Go tests. Ensure tests pass before opening PRs.
