Quick Start

import { print } from 'graphql';
import { generateDocument } from '@graphjson/core';

const { ast } = generateDocument({
  query: {
    users: {
      select: {
        id: true,
        name: true
      }
    }
  }
});

// Print the query
console.log(print(ast));

Output:

Usage

The printer is based on GraphQL's built-in print function and works with any GraphQL DocumentNode or AST node.

Basic Printing

import { print } from 'graphql';

const queryString = print(ast);

With Formatting

const formatted = print(ast);

// Result is automatically formatted with:
// - Proper indentation
// - Consistent spacing
// - Readable structure
