Top 7 React Native Local Database For App development

Introduction

A React Native Developer faces intense pressure to deliver a high-performing, offline-first app that can be scaled at any time. As a result, it can be difficult for developers to select the appropriate technology stack that includes the right database for React Native.

Are you in search of the best database for react native? Here is a list of React Native Local Database development in this blog. They may meet your requirements, such as easily scaling with your user base or supporting offline development capacities. However, before we get into the best local database in React Native app development, let’s go over the factors to keep in mind!

How to choose a database for React Native applications

1. Data Complexity

• It is determined that for most applications, data should be saved in the form of key values or a JSON structure. As a result, it is critical to choose a database that can handle complex data structures such as full documents or objects.

2. Memory Management

• Apps may crash more frequently if data is not handled properly. Although most databases clear their cache at regular intervals, this ensures that enough memory is available to run an app properly.

3. Offline synchronization of Data

• Users nowadays require their apps to work in offline mode as well as when their internet connection is slow. As a result, it is critical to integrate a database that allows data synchronisation when users reconnect to the internet.

4. Data Conflicts and Concurrency Handling

• The more collaboration-related features you include in your application, the greater the likelihood of data conflicts.

• Look for databases that share conflict-handling policies on their websites or repository pages. Examine the database documents to learn how they handle syncing and conflicts, or investigate the trade-offs made and the impact on the application.

5. Lines of code

• Any advanced database should be your last option if it takes more than 20 lines of code to write a simple CRUD operation. Because an advanced database would not only make coding more difficult but would also have a significant impact on database performance and the overall cost of developing a React Native app. Furthermore, processing so many code lines would significantly slow down the application.

• So, when choosing the best local storage for React Native in Expo, it’s essential to avoid databases with overly advanced functionality if they might degrade your app’s user experience or delay its release.

Which Are the Best React Native Local Databases For App Development?

1. Realm

• Realm is one of the best local database for React Native. The Realm database for react native was created to aid in the development of real-time and offline applications for wearable and mobile devices. The database has proven to be equally useful when developing React Native mobile apps for both iOS and Android. It is quite easy to use local storage in react native and Realm is the best database for it.

• It is not based on ORM or SQLite, so it has its own database engine and does not rely on key-value stores. This is one of the reasons why React Native app developers choose Realm as one of the local database React Native options when dealing with large amounts of data or developing high-performance applications. While other React Native local DB options exist for simple apps, the combination of the Realm database and React Native is unique.

Benefits of Realm In React Native

• Realm Sync – the sync services run in the background, recording and saving all user interactions and service requests locally.

• Offline friendliness via Redux Offline – Redux Offline can be a great option for those looking for a solution to implement offline-first architecture through Realm for React native apps.

• Security – It employs a variety of encryption standards for each mobile platform.

Pricing

• The Realm is a completely open-source and free local React database app. The pro version, on the other hand, is not free. However, if you buy the platform for creating React native apps, it will cost you $1750 per month.

2. Firebase

• Firebase is also one of the best databases for react native. For the development of React native applications, Firebase supports real-time NoSQL databases. It is chosen primarily for its offline data change and synchronisation capabilities. The reason why Firebase for Startups is so popular is that it is completely capable of handling the M and C of the MVC requirements for React native-based applications.

Benefits of using Firebase for React Native App Development

• Data syncing in real-time – with Firebase for React Native, data is synchronised in real-time for all clients at the same time. This is especially important when an app goes offline unexpectedly due to a lack of internet connection.

• Low setup effort – Firebase provides a cross-platform API that requires minimal setup when used within an application. Furthermore, you won’t need an application server to access the data because it can be accessed directly from a mobile phone.

• Offline persistence – the combination of Firebase and React Native allows developers to create real-time apps with offline persistence. This includes marking users’ presence as online or offline and storing a timestamp whenever they disconnect.

Pricing

• Firebase is a free React native storage service that offers up to 1GB of data storage. However, it does offer a minimum price of $25 for 2.5 GB of data storage as well as a pay-as-you-go package.

3. SQLite

• Sqlite was created to provide mobile applications with React native local storage databases. React Native SQLite storage is commonly used by developers. The prominence of the word Lite in the database name implies that it is a lightweight library with minimal setup requirements. It can also be directly integrated into the mobile application for direct database access. Hence it can add up to the list of the best database for react native. 

Benefits of using SQLite for React Native App Development

• Developers prefer to integrate SQLite into the app because of the benefits of React Native app with it. It is an ACID-compliant database that implements SQL standards with some omissions. The library’s architecture is file-based, and there are some tools that can handle all data types with ease and simplicity.

• Offline persistence – To enable SQLite offline persistence, developers can use a react-native-SQLite-storage plugin for data management within the application.

Pricing

• SQLite is free to use and open source because it is in the public domain. If you want to obtain a license for copyright infringement, you must pay a one-time fee of $6000.

4. PouchDB

• PouchDB is an open-source Javascript database that stores data in JSON format and allows developers to take full advantage of React Native by developing, reading, updating, querying, and deleting queries using a single JavaScript API. MySQL, CouchDB, PostgreSQL, and MongoDB are all supported.

Benefits of using PouchDB for React Native App Development

• Because PouchDB runs within a browser, there is no need to perform queries over the network. Overall, this results in faster query execution.

• Developers of React Native mobile apps can sync data with any supported server, utilizing a React Native offline database to ensure their applications run smoothly both offline and online.

5. Async Storage

• Async is also one of the best local databases for React Native. Async storage is a react native local storage database system that allows developers to store data locally and persist data across app restarts. The database is built with React Native and can be used without any additional setup.
