• Node.js: For LSP servers and tooling
• ripgrep (rg): For fast file searching
• Python 3: With pynvim package for Python support

Optional Dependencies

• Pandoc: For HTML to Markdown conversion
• Prettier: For code formatting
• Stylua: For Lua formatting

Installation

# Backup existing config (if any)
mv ~/.config/nvim ~/.config/nvim.bak

# Clone this configuration
git clone <your-repo-url> ~/.config/nvim

# Start Neovim (plugins will auto-install)
nvim

Debugging Setup

This configuration includes full debugging support for multiple languages using DAP (Debug Adapter Protocol).

Supported Languages

Language	Debug Adapter	Configuration
Java	java-debug-adapter	Auto-configured via nvim-jdtls
Node.js/NestJS/TypeScript	js-debug-adapter (pwa-node)	Launch & Attach configurations
Python	debugpy	Django, FastAPI, Flask, and general Python

Debug Configurations

Node.js/NestJS/TypeScript

• Launch NestJS - Runs dist/main.js with source maps
• Launch Current File - Debug the current TypeScript/JavaScript file
• Launch with ts-node - Debug TypeScript directly without compilation
• Attach to NestJS - Attach to running process on port 9229
• Attach to Process - Pick from running Node.js processes

Python

• Launch File - Debug current Python file
• Launch with Arguments - Debug with custom arguments
• Attach Remote - Attach to debugpy server (port 5678)
• Django - Debug Django with manage.py runserver
• FastAPI - Debug FastAPI with uvicorn
• Flask - Debug Flask application

Java

• Auto-discovers main classes and test methods
• Hot code replacement enabled
• Use <leader>jd to debug the current class

Installation

Debug adapters are automatically installed via Mason. Run :Mason to verify:

• debugpy - Python debugger
• js-debug-adapter - Node.js/TypeScript debugger
• java-debug-adapter - Java debugger
• java-test - Java test runner

Troubleshooting

Check Configuration Health

:checkhealth
:CheckConfig

Common Issues

1. Plugins not loading: Run :Lazy sync
2. LSP not working: Run :Mason and install required servers
3. Formatting not working: Ensure formatters are installed (prettier, stylua, etc.)
4. Slow startup: Check :Lazy profile for slow plugins
