Quickstart

npm install @onchaindb/sdk
# or
yarn add @onchaindb/sdk

import { createClient } from '@onchaindb/sdk';

const client = createClient({
  endpoint: 'https://api.onchaindb.io',
  appId: 'your-app-id',
  appKey: 'your-app-key'
});

const db = client.database('your-app-id');

// Create indexes - this also creates the collections
await db.createIndex({
  name: 'idx_users_email',
  collection: 'users',
  field_name: 'email',
  index_type: 'hash',
  options: { unique: true }
});

await db.createIndex({
  name: 'idx_users_createdAt',
  collection: 'users',
  field_name: 'createdAt',
  index_type: 'btree'
});

const result = await client.store({
  collection: 'users',
  data: [{
    email: 'alice@example.com',
    name: 'Alice',
    createdAt: new Date().toISOString()
  }]
});

console.log('Stored at block:', result.block_height);

// Simple query
const users = await client.query({
  collection: 'users',
  limit: 10
});

console.log(`Found ${users.total} users`);

// Using Query Builder
const activeUsers = await client.queryBuilder()
  .collection('users')
  .whereField('status').equals('active')
  .orderBy('createdAt', 'desc')
  .limit(10)
  .execute();
