Here's a quick example of how to use FerryDB:

import { Schema, model, connect } from 'ferrydb';

// Connect to the database
connect('path/to/your/database.sqlite');

// Define a schema
const userSchema = new Schema({
    name: { type: 'string', required: true },
    age: { type: 'number', required: true }
});

// Create a model
const User = model('User', userSchema);

// Create a new user
const newUser = User.create({ name: 'John Doe', age: 30 });

// Find a user
const user = User.findOne({ name: 'John Doe' });

// Update a user
User.update({ name: 'John Doe' }, { age: 31 });

// Delete a user
User.delete({ name: 'John Doe' });
