🚀 Core Life (Project-CL)

A private personal ERP to organize my life, built with modern tech stack and enterprise-grade infrastructure.

🌐 Live Production: core-life.arjunaa.my.id

📖 About The Project

Core Life is a personal ERP that I build for myself (now for public) to manage day by day activity, like manage your academic, financial, and more to come

This project is not just a basic CRUD app, but this project act as my playground to show how I implement FullStack, DevOps, Security, Infrastructure (Self-Host), and automation that simulate industry standard in a smaller scale.

✨ Key Features

• 🔐 Secure Authentication: Implementation of JWT Auth in the middleware
• ⚡ High Performance: Backend written in Golang to decrease latency and for high performance
• 📱 Responsive UI: Frontend React that is responsive for desktop & mobile
• 📚 Academic Module: Manage your classes, assignment, and your GPA
• 💵 Financial Module: Manage your money based on your needs, wants, save, dan invest.
• 🔜 More Modules to Come

🛠️ Tech-Stack

Frontend	Backend	Database	Devops	Infrastructure
React	Golang	Postgres	Docker	Ubuntu server
Tailwind	Gin		Github Action	Cloudflare tunnel

🏗️ Infrastructure & Architecture

This project is being hosted on my own Home Server (Used Laptop).

🔄 CI/CD Pipeline

Every code that has pas the review will automatically be added to the repo by GitHub Actions:

1. Branch dev: Auto-deploy to the Development environment (Port 8081/3001).
2. Branch main: Auto-deploy to the Production environment (Port 8080/3000).

🛡️ Network & Security

• Cloudflare Tunnel: Expose production to the public without port forwarding
• Tailscale: Private access to development environtment that I use.
• CORS Policy: Strict policy to separate API between dev and prod environtment

Loading

🌱 Getting Started (Local Development)

1. Git clone the project

Clone the project to open it locally

git clone https://github.com/Arjuna-Ragil/Project-CL.git
cd Project-CL

2. Create an .env in the root folder

Base config to start running the project

# Database config (change as needed)
DB_HOST=localhost
DB_USER=postgres
DB_PASSWORD=secret
DB_NAME=cl_local_db
DB_PORT=5432

# Backend config
SECRET_KEY=Secret_key_that_you_can_change
AUTH_MODE=false (enable/disable auth middleware)

3. Create an .env.local in the FE folder

Env to enable communication between FE and BE

VITE_API_BASE_URL=http://localhost:8080/api (change to correspond your backend)

4. Run in docker

There are two choice on how to run the project:

# Only build the database, run the FE & BE separately (Recommended)
docker compose up -d --build db

# Build everything from docker
docker compose up -d --build

5. Access web

• FE: http://localhost:5173
• BE: http://localhost:8080
