NGINX Terminal UI Manager (NgxTUI)

A modern, feature-rich terminal UI for managing NGINX servers, built with Bubble Tea and Go.

Features

• Interactive, keyboard-driven dashboard: Sites, Logs, Stats, and Metrics tabs
• Site management: enable/disable, config test, graceful reload, quick add
• Powerful template system for "Add Site" with 11 pre-configured templates:
  • Static, SPA, Node.js, WordPress, Laravel, Django, Docker/Proxy, WebSocket, Domain Redirect, API Gateway, Blank
• Auto-populated forms, validation, and quick-start guides per template
• NGINX config generation with SSL/TLS, proxy, PHP-FPM, and custom block support
• Real-time metrics: CPU, memory, network, request throughput with live charts
• Access log viewer: color-coded by status code, auto-scroll, quick filtering
• Statistics: site distribution and performance summaries
• Modular architecture: testable, production-ready, easy to extend
• Modern TUI styling with a clean dark theme

Installation & Build

Prerequisites:

• Go 1.24 or higher
• NGINX installed and running
• A Unix-like OS (Linux recommended)

Build from source:

git clone https://github.com/aitmiloud/ngxtui.git
cd ngxtui
make build
# or
go build -o bin/ngxtui ./cmd/ngxtui

Usage

Run the application (requires elevated privileges to manage NGINX configs):

sudo ./bin/ngxtui        # after building locally
# or
sudo make run            # build and run in one step

Notes:

• Sudo is required to read/write NGINX configuration files and reload the service.
• NgxTUI does not modify your configs without explicit actions from you.

Keyboard Controls

• ←/→ or h/l: Switch between tabs
• ↑/↓ or k/j: Navigate items
• Enter: Select/Execute action
• Esc: Go back
• a: Add site
• r: Refresh sites
• q: Quit application

Dependencies

• bubbletea: Terminal UI framework
• lipgloss: Style definitions
• bubbles: UI components

Troubleshooting

• Permission denied / operation not permitted

  • Run via sudo as shown above.
  • Ensure your user is allowed to reload NGINX (e.g., via sudoers).

• NGINX reload fails

  • Check syntax with sudo nginx -t.
  • Inspect error logs (e.g., /var/log/nginx/error.log).

• No sites listed / paths differ

  • Verify your NGINX sites-available and sites-enabled directories.
  • Customize paths in your system or adjust service configuration as needed.

• Colors or graphics look wrong

  • Use a terminal with true-color support.
  • Ensure TERM is set appropriately (e.g., xterm-256color).
