How to Use the GraphQL Query Builder

This tool helps you construct GraphQL queries with proper syntax, making it easier to work with GraphQL APIs.

Step-by-Step Instructions:

1. Enter query name: The root query field (e.g., "user", "posts")
2. List fields: Add fields you want to retrieve, one per line
3. Add nested fields: Use indentation and braces for nested objects
4. Add variables: (Optional) Define variables for dynamic queries
5. Build query: Click "Build Query" to generate the GraphQL syntax
6. Copy & use: Copy the query to use in your GraphQL client

Example Query:

Query Name: user

Fields:

id
name
email
posts {
  id
  title
  createdAt
}

Variables:

userId: 123

Generated Query:

query ($userId: Int) {
  user(userId: $userId) {
    id
    name
    email
    posts {
      id
      title
      createdAt
    }
  }
}

GraphQL Basics:

• Query: Read operation to fetch data
• Fields: Specific properties you want to retrieve
• Nested Fields: Related objects (e.g., user's posts)
• Variables: Dynamic values passed to the query
• Arguments: Parameters to filter or modify results

Common Use Cases:

• Learning GraphQL query syntax
• Building queries for GraphQL API testing
• Prototyping frontend data requirements
• Documenting GraphQL API usage
• Teaching GraphQL to team members

Tips:

• Use 2-space indentation for nested fields
• Wrap nested objects in curly braces { }
• Variable names should be camelCase
• Test your queries in GraphQL Playground or GraphiQL
