Installation

npm install @gitdb/client

Quick Start

Basic Usage

import GitDB from '@gitdb/client';

// Initialize client
const db = new GitDB({
  token: 'ghp_your_github_token_here',
  owner: 'your-username',
  repo: 'your-database-repo',
  host: 'localhost',
  port: 7896
});

// Connect and use
await db.connect();

const users = db.collection('users');

// Insert a document
const user = await users.insert({
  name: 'John Doe',
  email: '[e-mail]',
  age: 30
});

// Find documents
const allUsers = await users.find();
const john = await users.findOne({ name: 'John Doe' });

// Update document
await users.update(user.document.id, { age: 31 });

// Delete document
await users.delete(user.document.id);

await db.disconnect();

Environment Variables

Query Examples

Basic Queries

// Find all documents
const all = await users.find();

// Find with simple filter
const admins = await users.find({ role: 'admin' });

// Find with comparison operators
const youngUsers = await users.find({ age: { $lt: 30 } });
const activeUsers = await users.find({ lastLogin: { $gte: '2024-01-01' } });

// Find with logical operators
const specificUsers = await users.find({
  $or: [
    { role: 'admin' },
    { age: { $gte: 30 } }
  ]
});

const complexQuery = await users.find({
  $and: [
    { age: { $gte: 18 } },
    { $or: [
      { role: 'admin' },
      { role: 'moderator' }
    ]}
  ]
});

Update Operations

await users.update(userId, { age: 31, updatedAt: new Date() });

// Update multiple documents
await users.updateMany(
  { role: 'user' },
  { lastLogin: new Date().toISOString() }
);

GraphQL Examples

Basic Queries

// Get all collections
const collections = await db.graphql.query(`
  query GetCollections {
    collections
  }
`);

// Get documents from a collection
const products = await db.graphql.query(`
  query GetProducts {
    products {
      id
      data
    }
  }
`);

// Query with variables
const userProducts = await db.graphql.query(`
  query GetUserProducts($userId: String!) {
    products(where: { userId: $userId }) {
      id
      data
    }
  }
`, { userId: 'user123' });

Mutations

// Create document
const newProduct = await db.graphql.mutation(`
  mutation CreateProduct($data: JSON!) {
    createProduct(data: $data) {
      id
      data
    }
  }
`, {
  data: {
    name: 'Laptop',
    price: 999.99,
    category: 'Electronics'
  }
});

// Update document
const updated = await db.graphql.mutation(`
  mutation UpdateProduct($id: String!, $data: JSON!) {
    updateProduct(id: $id, data: $data) {
      id
      data
    }
  }
`, {
  id: 'product123',
  data: { price: 899.99 }
});

// Delete document
const deleted = await db.graphql.mutation(`
  mutation DeleteProduct($id: String!) {
    deleteProduct(id: $id)
  }
`, { id: 'product123' });

Error Handling

try {
  const user = await users.findById('non-existent-id');
} catch (error) {
  if (error instanceof GitDBQueryError) {
    console.error('Query error:', error.message);
    console.error('Status code:', error.statusCode);
    console.error('Details:', error.details);
  } else if (error instanceof GitDBConnectionError) {
    console.error('Connection error:', error.message);
  } else if (error instanceof GitDBValidationError) {
    console.error('Validation error:', error.message);
  }
}

TypeScript Support

The SDK includes comprehensive TypeScript definitions:

import GitDB, { 
  GitDBConfig, 
  Document, 
  Collection, 
  GitDBError,
  GitDBConnectionError,
  GitDBQueryError,
  GitDBValidationError
} from '@gitdb/client';

// Type-safe configuration
const config: GitDBConfig = {
  token: 'ghp_...',
  owner: 'username',
  repo: 'database',
  host: 'localhost',
  port: 7896
};

// Type-safe documents
interface User extends Document {
  name: string;
  email: string;
  age: number;
  role: 'admin' | 'user' | 'moderator';
}

const users = db.collection('users');
const user: User = await users.findById('user123');
