Nowadays, React Native developers are in a lot of pressure for creating a high-performance application which works in the offline mode and can be scaled as per the requirements. But, there are a lot of prerequisites to develop such apps.

In this writeup, we will be discussing one such important prerequisite that is React Native database. We can call it the backbone of React Native applications. So, let’s dig into the list of the best backend for React Native in 2024.

Wait, before getting deep into the database, it is essential to have a look at the aspects to consider while choosing the React Native DB.

Points To Take Note While Choosing React Native Database

Ease of Use

It is always important that you choose a React Native database that can be integrated with minimal efforts. But, how will you choose the best database? The optimal approach is to hire React Native developers or consultants with experience in app database management.


Once an app gets popular, the work of developers increases and a huge amount of data is to be managed now. A lot of requests will be coming from the users and it is quite tough to serve the correct data to them. Therefore, it is utmost important to know about the concurrency mechanism implemented by the different React Native local database.

Memory Management

When data is not managed in a proper way, the chance of application to get crashed increases. Although, most of the databases typically clear their cache in time intervals which ensures that enough memory is available to run an application perfectly.

Offline Data Synchronization

These days users want their application to work in the offline mode too or when the internet connection is down. Henceforth, it is essential to integrate the database that enables data sync when the user is connected back to the internet.

Data Complexity

It is analyzed that for most of the apps, data is stored either in the form of a JSON structure or key values. This makes it important to choose a database which can handle the complex data structures like objects or full documents.

3. SQLite DataBase

SQLite DataBase

SQLite – the most popular and used database engine across the global. This database is built especially for mobile devices. Considering this, SQL database is small, fast, and highly reliable to be integrated with any application.

This React Native DB does not run on any separate server but will write the content directly into the various files. The data is stored by SQLite in the plain text format, which you can even encrypt with SQLite Encryption Extension (SSE).

The extension will encrypt the data, as well as metadata for a, react native application. Here every database file will have their own unique key for the decryption. SSE is licensed software, yet you can buy the source code for $2000.

Pricing: SQLite is a public domain, henceforth free to use. To get the perpetual right to use the source code, you need to pay $6000(one-time fee).

Advantages of SQLite

  • The database in the ACID compliant means it implements almost every SQL standard.
  • You can enable the offline persistent in the app with the help of the react-native-SQLite-storage.
  • SQLite will save the data in the cross-platform database file.

4. PouchDB DataBase

PouchDB DataBase

An open-source Javascript database that will store the data in JSON format. The API here will give you access to the database with just a single call React Native platform. PouchDB enables you to create, update, delete, read and query the object for your API.

PouchDB uses HTTP protocol and JSON, therefore this database is highly compatible with almost every application. It also uses IndexedDB for saving the data to the browser when there is no internet connection.

When the internet connection is back, the data is synced to the backend servers like CounchBD. This react native database is extremely fast with the complex data structures. To secure your data, you can use pouchdb-authentication plugin.

Pricing: PouchDB is free to use, but you are opting for CouchDB, you have to pay for CouchDB cluster. You can easily find all the updates of PouchDB on GitHub.
