Nginx configuration file online formatting - beautify your Nginx code

This tool, based on prettier-plugin-nginx, provides online formatting, beautification, and indentation optimization for Nginx configuration files. Simply paste nginx.conf or related configuration content to instantly restructure the configuration, making it clearer, easier to read, and easier to maintain. This tool is completely free and requires no installation. It's suitable for operations engineers, backend developers, and server configuration debugging scenarios.

Inspiration

Nginx is widely used in daily operations and service deployment, but configuration files often suffer from confusing indentation and inconsistent styles, hindering understanding and collaboration. This tool was inspired by this common pain point. Leveraging Prettier and the plugin ecosystem, it automates Nginx configuration file formatting, helping developers and operations personnel quickly organize their code and reduce human error.

Instructions

1. Open the tool page and paste the contents of the Nginx configuration file into the input box.

2. Click "Format" and the tool will automatically optimize indentation, line breaks, and structure.

3. Copy the formatted result with one click for actual deployment or backup.

   No installation required; complete online.

Application Scenarios

• Organize complex nginx.conf files for a clear structure and easier maintenance.

• Standardize configuration file styles during team collaboration to avoid indentation and formatting differences.

• Quickly check syntax and structure when debugging and optimizing Nginx configurations.

• Demonstrate standardized Nginx configuration examples for teaching and learning.

Implementation Principle

This tool relies on Prettier and prettier-plugin-nginx to parse and structure configuration files, regenerating them in a unified format while maintaining semantic correctness. It supports common formatting rules such as automatic indentation, line breaks, and hierarchical optimization. It does not change the configuration logic, but only improves readability.

FQA

1. Will formatting change my Nginx configuration logic?

   No. This tool only adjusts indentation and formatting; it does not affect command logic or parameter settings.

2. Will my configuration be saved?

   No. The tool runs only in the browser and does not upload or store configuration data.

3. Why do I get a parsing error?

   This usually indicates a syntax error in the configuration file (such as a missing semicolon or mismatched braces). Please correct the error before attempting to format.

4. What is the difference between this tool and the Nginx Configuration Checker?

   This tool focuses on formatting and beautification, while the checker primarily checks configuration syntax. The two tools work best together.
