gqlg
✓ const gqlg = require('gql-generator')
This package is primarily a CommonJS module for programmatic access or a CLI tool. ESM import is not directly supported for the main `gql-generator` function, though generated output can be consumed in ESM contexts using `import`.
generatedQueries
✓ const queries = require('./path/to/output')
✗ import queries from './path/to/output'
The generated `index.js` files and sub-modules use CommonJS `module.exports`. While Node.js 18 supports ESM, direct `import` of these generated files will fail without explicit `type: 'module'` in the output directory's `package.json` or a transpilation step. Stick to `require()` for broad compatibility.
generatedMutations
✓ const mutations = require('./path/to/output/mutations')
✗ import { signup } from './path/to/output/mutations'
Individual query/mutation files are also CommonJS modules. Access specific operations via object destructuring on the `require` result, e.g., `const { signup } = require('./mutations');` if the module directly exports named properties, or through the property access as shown in the examples (`mutations.signup`).
This quickstart demonstrates programmatically generating GraphQL queries and mutations from an in-memory schema string, writing them to a temporary directory, and then requiring the generated files.
const gqlg = require('gql-generator');
const path = require('path');
const fs = require('fs');
const schemaContent = `
type Query {
user(id: Int!): User!
posts: [Post!]
}
type Post {
id: Int!
title: String!
author: User!
}
type User {
id: Int!
username: String!
email: String!
}
`;
const schemaPath = path.join(__dirname, 'sampleTypeDef.graphql');
const outputPath = path.join(__dirname, 'output');
// Ensure schema file exists for the generator
fs.writeFileSync(schemaPath, schemaContent);
// Ensure output directory exists
if (!fs.existsSync(outputPath)) {
fs.mkdirSync(outputPath, { recursive: true });
}
async function generateQueries() {
console.log('Generating GraphQL queries...');
await gqlg({
schemaFilePath: schemaPath,
destDirPath: outputPath,
depthLimit: 2,
includeDeprecatedFields: false,
includeCrossReferences: false
});
console.log(`Queries generated in ${outputPath}`);
// Example of requiring generated queries
const generated = require(outputPath);
console.log('\nGenerated User Query:\n', generated.queries.user);
console.log('\nGenerated Posts Query:\n', generated.queries.posts);
// Clean up generated files for subsequent runs (optional)
fs.rmSync(outputPath, { recursive: true, force: true });
fs.unlinkSync(schemaPath);
}
generateQueries().catch(console.error);

Errors
Common errors & fixes
Error: ENOENT: no such file or directory, open './schema.graphql'
The `schemaFilePath` provided to the `gql-generator` CLI or programmatic function does not point to an existing GraphQL schema file.
fixVerify that the `schemaFilePath` argument correctly specifies the path to your `.graphql` or `.gql` schema definition file, and that the file exists at that location. Use an absolute path or a path relative to the process's current working directory.
ReferenceError: require is not defined in ES module scope
Attempting to `require()` the generated output files (or the `gql-generator` package itself if it were ESM) from within an ES Module (`.mjs` file or `type: 'module'` in `package.json`) context.
fixEnsure your consuming script for the generated files is running in a CommonJS context (e.g., a `.js` file without `type: 'module'`). If you must use ESM for consumption, you may need to dynamically `import` the CJS module or adjust your build system.
