BoxDB is a promise-based browser ORM for [IndexedDB](https://developer.mozilla.org/en-US/docs/Web/API/IndexedDB_API)

</div>

```typescript
import BoxDB from 'bxd';

const db = new BoxDB('my-database', 1);

// Define your box (Object store)
const User = db.create('user', {
  id: {
    type: BoxDB.Types.NUMBER,
    key: true, // This property is in-line-key
  },
  name: {
    type: BoxDB.Types.STRING,
    index: true, // This property is index
  },
  age: BoxDB.Types.NUMBER,
});

await db.open();

// Basics
await User.add({ id: 1, name: 'Tom', age: 10 });
await User.get(1);
await User.put({ id: 1, name: 'Tommy', age: 12 });
await User.delete(1);

// find(range, ...filters) method using IDBCursor
// Get records
const records = await User.find().get();

// filter & sort & limit
await User.find(
  null,
  (user) => user.id % 2 !== 0,
  (user) => user.age > 10,
  (user) => user.name.includes('y'),
).get(BoxDB.Order.DESC, 10);

// Update records (with filter)
await User
  .find(null, (user) => user.age !== 0)
  .update({ name: 'Timmy' });

// Delete records (with IDBValidKey & IDBRange + IDBIndex)
await User
  .find({
    value: BoxDB.Range.equal('Timmy'),
    index: 'name',
  })
  .delete();

// Do multiple tasks in one transaction
await db.transaction(
  User.$put({ id: 1, name: 'Tim', age: 20 }),
  User.$add({ id: 2, name: 'Jessica', age: 15 }),
  User.$add({ id: 3, name: 'Ellis', age: 13 }),
  User
    .$find({ value: 3 })
    .put({ name: 'Tina' }),
  BoxDB.interrupt(); // You can stop transaction like this!
  User.$delete(2),
  User
    .$find(null, (user) => user.age < 20)
    .put({ name: 'Young' }),
);

// And other IndexedDB API features!
await User.count(); // Get all records count
await User.clear(); // Clear all records
```
