The Best Database for Your React Native App: Which One Should You Choose?

This article is meant to be an introductory piece for developers who are looking for advice on how to best store their data in a React Native project. It is written to help you make the right choice by examining various databases and their pros and cons. 

Choosing the right database for your React Native app is a difficult and confusing process. There are so many options out there and if you don’t know what you’re doing, you might end up having to switch databases halfway through development.


Producing quality React Native apps on time and on a budget is hard enough on its own, without having to worry about whether or not your database will work for you. Save time by making the best decision upfront, and invest in a database that will provide real value to your team. With the right choice, you can save time and money by building it with simplicity in mind. 

What is a Database?

A database is a structured set of data, frequently linked together. Database providers provide it as a set of data structures to easily store and retrieve that data. There are some important things to consider before creating databases for your React Native Mobile app, they include but are not limited to,

React Native App
  • Whether your React Native application reads synchronously or asynchronously
  • Whether you’re managing more than 100,000 users
  • Whether your React Native application is hosted


Why Should I Use A Database?

The React Native world is constantly evolving and it is important for developers to be always up to date on the latest technologies. Mobile application architecture is getting smarter and faster. As mobile apps and their backend frameworks get smarter, you’ll be able to avoid race conditions and async code complexity. That would allow you to skip complicated queues. Even React Native will be able to resolve deadlocks and slowdowns to deliver consistent performance in the end. Relational databases have been the preferred database option for most mobile app developers for several years now. The React Native community is also adopting some concepts from relational databases. In fact, popular technology trends have placed relational database technology and React Native together.

The Top Database Options for React Native

Firebase for React Native

Firebase is a mobile platform for building software for iOS, Android, and the web. It uses JavaScript instead of HTML or Java. And it focuses on ease-of-use and ease-of-deployment. It has features like offline-first, push notifications, and server-side rendering, which enables you to build React Native apps easily. 

Developers are able to test and debug their apps locally on devices or in the cloud. And they can add capabilities like game physics, multiplayer interactions, and more. Webpack is a development tool and a module bundler. It reduces the complexity of building and deploying apps by bundling components. It also supports declarative configuration. It’s completely free, easy-to-use, and has a community.

Benefits of Firebase


Firebase as a toolset has capabilities and utilities for storing data and analytics for your mobile applications. Firebase allows you to use familiar tools such as CouchDB, SQL, MongoDB, and many others. This helps developers and teams to gain quick insights and also easily visualize the data.

For example, Firebase makes it easy for you to store local user data with Node.js. There are plenty of Node.js tools which allow you to make a simple connection and store data for faster performance and quick access. Firebase also supports multiple databases such as CouchDB, MongoDB, and Firebase Storage.


Many big companies such as Airbnb, Kik, Live. I and others use Firebase as an important part of their development. If you are developing a mobile app and want to include in-app analytics, firebase is an excellent choice.

MongoDB for React Native

People who have been transitioning from MySQL to MongoDB are often surprised by how easy the transition is.  if you have asked yourself, “Why should I migrate from MySQL to MongoDB?”

People who have been transitioning from MySQL to MongoDB are often surprised by how easy the transition is.  if you have asked yourself, “Why should I migrate from MySQL to MongoDB?”

MongoDB is your go-to database for React Native apps. MongoDB is also a top choice for React Native developers. It’s no surprise why because it has many of the attributes you need to build an efficient React Native application.

MongoDB allows you to build multiple backends that can handle two to eight database backends, depending on the model of your application. You can choose different database backends, and you can connect them to your React Native app from several different developer tools. To make your transition from MySQL to MongoDB, you should have a few requirements in place.
