@mearie/codegen

Code generation utilities for Mearie GraphQL client.

This package provides the core code generation logic that can be reused across different build tool integrations (Vite, Webpack, Rollup, etc.).

Features

• Scanner: Scans files for GraphQL operations
• Generator: Generates TypeScript types from GraphQL operations and schema
• Writer: Writes generated types to the filesystem

Usage

import { runCodegen, scanDocuments, generateTypes, writeTypes } from '@mearie/codegen';

// High-level API
await runCodegen({
  schema: 'schema.graphql',
  documents: 'src/**/*.ts',
  cwd: process.cwd(),
});

// Low-level API for custom workflows
const operations = await scanDocuments(
  {
    include: 'src/**/*.ts',
    exclude: 'node_modules/**',
  },
  process.cwd(),
);

const { types, augmentation } = await generateTypes(operations, schemaContent);

await writeTypes({ types, augmentation });
