🚀 Server Pulse: The Ultimate Coolify PaaS Demo

Server Pulse is a high-visibility diagnostic ecosystem built to demonstrate the power of self-hosted PaaS solutions. While typical "Hello World" apps only verify static delivery, Server Pulse stress-tests the entire infrastructure stack: from stateful database persistence to internal container networking.

🎯 The "Why"

This project was engineered to test and where possible solve the Infrastructure Sanity Check problem. When moving from Vercel or Heroku to a self-hosted solution like Coolify, developers need to verify that:

1. Networking: The App can talk to the DB securely over a private network.
2. Persistence: Data survives container restarts and redeployments.
3. CI/CD: Git webhooks and Nixpacks builders are injecting the correct metadata.
4. Resources: The container has access to the expected system resources (RAM/CPU).

🛠️ Tech Stack

• Frontend/Backend: SvelteKit 5 (utilizing Runes for high-performance reactivity)
• Styling: Tailwind CSS (Modern, dark-mode first UI)
• Database: PostgreSQL (Relational persistence)
• Infrastructure: Coolify PaaS + Nixpacks (Auto-detecting runtime)

📊 Monitored Metrics

Server Pulse exposes real-time environment data that traditional static apps can't reach:

• Resource Consumption: Resident Set Size (RSS) Memory, System Uptime, and Load Averages.
• Connectivity: Visitor IP tracking, Protocol (HTTP/2) detection, and platform identification.
• DevOps Metadata: Automatic injection of Git Commit Hashes and Docker Container IDs to verify deployment versions.

🚀 Quick Deployment (Coolify)

1. Provision Database:

• New Resource > Database > PostgreSQL.
• Note the Internal Connection String.

2. Create Table: - Open the Coolify Terminal for your DB and run:

CREATE TABLE pulses (id SERIAL PRIMARY KEY, created_at TIMESTAMP WITH TIME ZONE DEFAULT CURRENT_TIMESTAMP, user_agent TEXT, ip_address TEXT, server_info TEXT);

3. Deploy App:

• New Resource > Public Repository > [Your-Repo-URL].
• Add Env Var: DATABASE_URL = [Your-Internal-Connection-String].
• Set FQDN (e.g., https://pulse.yourdomain.com).
• Deploy.

Built to prove that self-hosting doesn't have to be hard.

Now, it's your turn to show me what you have got

After you, I will add the containerization with docker, which again Coolify greatly excels at
