hyperdb

// This quickstart assumes you have already run a builder script (like the one in the README) // to generate your database definition files in './spec/hyperdb/index.js'. import HyperDB from 'hyperdb'; import def from './spec/hyperdb/index.js'; // The generated database definition async function run() { // Choose your engine: .rocks for local-only, .bee for P2P // For this example, we'll use RocksDB locally. // Replace './my-local-db' with a suitable path for your database files. const db = HyperDB.rocks('./my-local-db', def, { writable: true }); await db.ready(); // Ensure the database is initialized and ready for operations // Add some entries console.log('Inserting members...'); await db.insert('@example/members', { name: 'Alice', age: 30 }); await db.insert('@example/members', { name: 'Bob', age: 25 }); await db.insert('@example/members', { name: 'Charlie', age: 30 }); await db.flush(); // Commit changes to the database console.log('Querying for Alice by name...'); const alice = await db.get('@example/members', { name: 'Alice' }); console.log('Found Alice:', alice); console.log('Querying for members with names starting C or later (via index)...'); // The example index 'members-by-name' has a 'mapNameToLowerCase' helper. const olderMembersStream = db.find('@example/members-by-name', { gte: { key: 'c' } }); const olderMembers = await olderMembersStream.toArray(); console.log('Members with names starting C or later:', olderMembers.map(m => m.name)); console.log('Getting one specific member by name using findOne...'); const bob = await db.findOne('@example/members', { name: 'Bob' }); console.log('Found Bob:', bob); await db.close(); // Close the database connection to release resources console.log('Database closed.'); } run().catch(console.error);
