# 🗃 swift-database
> `swift-database` is a module that allows you to interact easily with your local JSON file.
## 🔰 Getting started
1. Install the module
```
npm install swift-database
```
2. Initialize the database class
```javascript
const { default: JSONDatabase } = require('swift-database');
const database = new Database({
filePath: 'path/to/file.json'
});
```
3. Create your first table and load it
```javascript
database.createTable('users');
const users = database.table('users');
```
4. Interact with that table
```javascript
users.createOne({
fullName: 'John Doe',
hobbies: ['programming', 'sport']
});
const userDocument = users.findOne(
(userDocument) => userDocument.value.fullName === 'John Doe'
);
users.deleteOne(userDocument.id);
```
