React native database: How to choose it and the best one for app development

React is a JavaScript framework that helps you enter the code domain with an affordable price. If you want to effectively work with React Native, first, you need to gain sufficient understanding about React Native database – the crucial part of the application. In this blog, we will deliver you sufficient understanding about React native database, and databases for your React Native app

What is the React Native?

Firstly, we need to fully understand about React Native. This is a Javascript framework that allows you to write natively rendering applications for mobile devices. In fact, React Native supports mobile platforms rather than browsers. You can use React Native on both Android and iOS. Moreover, the framework draws from React, the Javascript library that Facebook uses to for developing user interface, or UI

The reason why it’s called React Native is that it allows developers to write “ native” mobile applications with existing JavaScript library. Thanks to that, you can save a lot of time and effort when working with React Native

React Native applications are written with both XML – markup ( JSX) and Javascript. Moreover, React Native renders APIs in Java for Android and Objective -C for iOS. Therefore, the application will render with the components of a real mobile user, not web views. Thanks to this, it feels like mobile application

Why should you use React Native to build mobile apps?

Now, let’s go over some outstanding benefits of React Native before moving to React Native database

Cost and time – effective

If you’re looking for a cost – effective way to build mobile apps, React Native will come in handy. The code used for the app in React Native can be used for other platforms. Thanks to that, you will be able to create cross – platform iOS/ Android in a short time. Thus, you can reduce the amount of paid working hours

Moreover, most of the coding in React Native are common codes. Hence, it won’t take you too much time debugging the errors

Highly flexible

React Native is one of the most flexible platforms out there. In particular, it delivers developers a lot of options for customization. Moreover, you can add third – party plugins in React Native as well. 

Can meet high technological standard

One of the best benefits of React Native is that it shares about 90% of the code among Android and iOS. Therefore, there is no need for numerous teams of developers for iOS and Android. This will not only save you a lot of cost, but also avoid chaos and complicate process

Pre – built components

React Native includes a lot of pre – built components that you can use for your apps. Imagine you need some codes for a specific function of your mobile app. Then, you can use those of other developers completely free

Ability to refresh the app during the development

This might be one of the most outstanding features of React Native. You can not only refresh the app during the development phase, but also refresh it with the changing codes. Moreover, you can keep track of all the changes with live – tracking

A wide range of plugins

React Native is such a flexible platform. It allows you to add plugins as you need. 

Declarative coding style and modular architecture

With Declarative coding, the React Native development process will be a lot faster and smoother. Moreover, the Modular program helps developers easily distinguish any program’s functionalities into separate modules. What’s more, you will be able to check other projects simultaneously. Needless to say, you can spare a lot of time for other tasks

Simple user interface ( UI)

Developing a mobile app is difficult. Then, React Native makes this daunting development a lot easier with its simple user interface. Also, it regulates every step’s procedure. As a result, you will find it a lot easier when working with React Native

How to choose the best React Native database

Now, let’s move to the React Native database. To choose the best one for your app development, you need to consider these following factors.

Data complexity

When it comes to React Native databases, data is one of the crucial factors. Ideally, you should choose a database that helps you handle and store more complex data including full documents and objects with complex data types

The number of lines of codes

In case you have to write more than 20 lines of codes for a simple CRUD operation, then you should avoid advanced databases. Here are some reasons why. Firstly, advanced databases will make the coding more complicated. Thus, it can greatly affect the performance of the database. For example, it can slow down the application greatly. What’s more, the more lines of codes, the more you’ll have to pay. Therefore, you might end up with higher expense than you expect.

Syncing of the offline data

If you’re not developing a complex application, which doesn’t offer multiple – user collaboration, then a simple database will work well for you. On the other hand, if the collaboration is the primal feature of your application, you’ll need complex database for your syncing functionality

How well it handle data conflicts and currency

This is one of the important factors when choosing a React Native database. The more collaboration related features you add into your applications, the more the data conflicts would be. Then, to choose the database which can best handle the data conflicts, you have to look into the database documents. Thanks to this, you will know how the database handles syncing and conflicts

Memory management.

Poor memory management can lead to app crashes. You might not want this to happen. Therefore, to avoid this, you should check the compaction to ensure the memory management. Compaction is where the documents of data used are deleted from the memory. This process will ensure if there is free memory available at any given point in time.
