Hooks for Dexie

dexie-hooks

There is now an official replacement for this!

See Dexie's official docs on useLiveQuery

Old docs for reference

Dexie hooks make it easy to use Dexie in React. If you're using Dexie.Observable they will respond to changes to the database.

• useTable(db.table) - uses an entire table.
• useItem(db.table, id) - uses a single item in the table.

import { useTable, useItem } from 'dexie-hooks';
import db from './my/db';

const AllUsersComponent: React.FC = props => {
    const [allUsers, loading, error] = useTable(db.users);

    if (loading) {
        return <Spinner />;
    }

    if (error) {
        return <div>{error.message}</div>;
    }

    return (
        <ul>
            {allUsers.map(user => (
                <li key={user.id}>{user.name}</li>
            ))}
        </ul>
    );
};

const OneUserComponent: React.FC = props => {
    const [user, loading, error] = useItem(db.users, props.userId);

    if (loading) {
        return <Spinner />;
    }

    if (error) {
        return <div>{error.message}</div>;
    }

    return (
        <div>
            <img src={user.image} /> {user.name}
        </div>
    );
};
