Which database is best for React Native?

The most popular database for React Native is an SQLite database.

It seems there might be a slight confusion in your question. AngularJS is a JavaScript-based framework for building web applications, and it is not directly related to databases. AngularJS applications typically interact with a backend server that manages the data storage and retrieval.

On the other hand, React Native is a framework for building mobile applications using React and JavaScript. Like AngularJS, React Native is also not directly associated with a specific database. The choice of a database for a React Native application depends on the backend technology you are using.

If you are referring to databases for the backend server that supports AngularJS or React Native applications, the choice of the database depends on various factors such as the project requirements, scalability needs, and the expertise of the development team. Common choices include relational databases like MySQL or PostgreSQL, NoSQL databases like MongoDB, or cloud-based solutions like Firebase.
