GraphQL Beautifier

The GraphQL Beautifier is a free online tool that formats and beautifies GraphQL queries, mutations, subscriptions, and schemas. GraphQL is a query language for APIs that allows you to request exactly the data you need. This tool helps you format your GraphQL code with proper indentation, line breaks, and structure, making it more readable and maintainable.

What is GraphQL?

GraphQL is a query language and runtime for APIs developed by Facebook. It provides a more efficient, powerful, and flexible alternative to REST APIs. GraphQL allows clients to:

• Request Specific Data: Query exactly the fields you need
• Single Endpoint: Use a single endpoint for all data operations
• Strongly Typed: Schema defines the structure and types
• Introspection: Query the schema to understand available data

How Does It Work?

The tool uses the graphql-prettier library to format your GraphQL code:

1. Parse GraphQL: The tool parses your GraphQL query or schema
2. Format Structure: Applies proper indentation and line breaks
3. Optimize Layout: Organizes fields, arguments, and fragments for readability
4. Output Formatted Code: Returns beautifully formatted GraphQL code

How to Use the GraphQL Beautifier

1. Enter GraphQL Code: Paste your GraphQL query, mutation, subscription, or schema
2. Set Indent Size: Choose your preferred indentation (1-8 spaces)
3. Auto Formatting: The code is formatted automatically as you type
4. View Output: See the formatted GraphQL in the output field
5. Copy or Download: Copy the formatted code or download it as a file

Key Features

• Automatic Formatting: Formats GraphQL queries, mutations, and schemas
• Proper Indentation: Consistent indentation for nested structures
• Field Organization: Organizes fields and arguments clearly
• Fragment Support: Formats GraphQL fragments properly
• Variable Support: Handles GraphQL variables correctly
• Directive Support: Formats GraphQL directives
• Customizable Indent: Adjustable indentation size (1-8 spaces)
• Real-time Formatting: Instant formatting as you type
• File Upload: Upload .graphql or .gql files
• Copy & Download: Easy copy and download functionality

GraphQL Syntax Elements

The tool formats all major GraphQL syntax elements:

• Queries: Read data from the API
• Mutations: Modify data on the server
• Subscriptions: Real-time data updates
• Fields: Request specific data fields
• Arguments: Pass parameters to fields
• Fragments: Reusable field sets
• Variables: Dynamic query parameters
• Directives: Conditional field inclusion
• Schemas: Type definitions and schema

Example Formatting

Before Formatting:

query GetUser($id: ID!) { user(id: $id) { id name email posts { id title content } } }

After Formatting:

query GetUser($id: ID!) {
  user(id: $id) {
    id
    name
    email
    posts {
      id
      title
      content
    }
  }
}

Use Cases

• Code Readability: Make GraphQL queries more readable and maintainable
• Documentation: Format queries for documentation and examples
• Code Reviews: Standardize GraphQL code formatting in reviews
• Learning: Understand GraphQL structure through formatted examples
• API Testing: Format queries before testing in GraphQL playgrounds
• Version Control: Consistent formatting for better git diffs

GraphQL Best Practices

• Use Descriptive Names: Name queries, mutations, and fields clearly
• Request Only Needed Fields: Query only the data you need
• Use Fragments: Reuse common field sets with fragments
• Organize Nested Fields: Properly indent nested structures
• Use Variables: Use variables for dynamic values
• Format Consistently: Use consistent formatting across your project

Supported GraphQL Features

• Queries: Format query operations with fields and arguments
• Mutations: Format mutation operations
• Subscriptions: Format subscription operations
• Fragments: Format inline and named fragments
• Variables: Format variable definitions and usage
• Directives: Format include, skip, and custom directives
• Aliases: Format field aliases
• Arguments: Format field and directive arguments
• Type Definitions: Format schema type definitions

Tips for Best Results

• Valid Syntax: Ensure your GraphQL code has valid syntax for best results
• Consistent Indentation: Choose an indent size and stick with it
• Review Output: Always review the formatted output to ensure it's correct
• Use Fragments: Break down complex queries into fragments
• Test After Formatting: Test your formatted queries to ensure they still work
