!CHAPTER Details on FoxxRepository

A repository is a gateway to the database. It gets data from the database, updates it or saves new data. It uses the given model when it returns a model and expects instances of the model for methods like save. In your repository file, export the repository as *repository*.

```javascript
Foxx = require("org/arangodb/foxx");

TodosRepository = Foxx.Repository.extend({
});

exports.repository = TodosRepository;
```
