Neovim Configuration

A comprehensive Neovim configuration for jaehong21 powered by lazy.nvim package manager, featuring modern LSP integration, extensive plugin ecosystem, and multi-language development support.

Package Manager: lazy.nvim

This configuration uses lazy.nvim, a modern plugin manager for Neovim that provides:

• Lazy Loading: Plugins are loaded only when needed, improving startup time
• Automatic Installation: Missing plugins are automatically installed on first run
• Lockfile Support: lazy-lock.json ensures reproducible plugin versions
• Performance Monitoring: Built-in profiling to track plugin load times
• Simple Configuration: Each plugin is configured in its own file under
• Configuration Merging: opts tables are automatically merged when importing specs, enabling modular configuration of tools like conform.nvim and nvim-lint across multiple files lua/plugins/
• Dependency Management: Automatic handling of plugin dependencies
