React Native for Local Database – All You Need to Know

Mobile application development is getting more and more popular these days. Studies show that a career in coding mobile apps will have huge growth in the coming future compared to other occupations. Coding is growing day by day. In the present world, everything is dependent on technology. This is a technology-driven world. The evolution in technology will also force changes in software, Information Technology, and other related fields. Mobile applications are developed with the help of programming languages. Knowledge in coding and programming language is the basic requirement of developing applications. When it comes to the design and contents of application which varies according to purpose, frameworks and tools are used. Most Programming languages provide their frameworks and tools.

React Native is a framework that mainly focuses on developing mobile applications. It is backed by the Javascript programming language. React Native is developed by Facebook. Native application developers mostly rely on React Native. The key feature of this framework is its cross-platform use. A single code can be used across platforms. React Native is used to developing applications for iOS and Android Platforms. React Native is likely to support more platforms in the coming future.

Factors to ponder choosing a local database

For a high-performing and offline-first apps development, there is a need for local databases. The clients will always look for high-performing apps. As a developer, these demands will increase pressure. The developers need to find out the right local database for this purpose. There are so many local databases available for React Native. Choosing the correct database will help the developer to code high-performing applications. Before choosing a local database, the following factors have to be considered:

• Handling of Memory

The handling of data must be very careful. Any errors happening will lead to the crashing of the application. The database selected must have sufficient memory to handle data. Some local databases clear cache themselves and make room for enough storage.

• Data Complexity

Data is stored mostly in a key structure. This enables the storage of enough data without overwriting or duplications. So the local database selected must have the capacity to store maximum data without any duplications or any other errors. By storing in key structure, the whole documents can be stored and the chance of data loss is very less.

• Offline Synchronisation of Data

Even the internet is widely available, some areas have poor connectivity and no connectivity. People here will go for offline apps. For offline applications synchronization of data offline is needed for smooth functioning. Choosing a database that can synchronize offline data will give a better user experience

• Complex Data

When we add more data to the application, there is a chance of data becoming complex. This also leads to app crashes. So choosing a local database that helps in reducing data complexity will give better performance to the application

• Ease of Use

A general factor that is preferred by all developers. All developers choose a database that is easy to use. The development of the application itself is a complex process. Developers cant waste more time on fixing databases. So they prefer fast and easy-to-use databases.

React Native for Local Databases

There are a lot of local databases which are supported by React Native. Let us go through some of them.

1. Realm

An object-oriented local database. It is also an open-source database. It supports complicated data. Data complexity will be handled better by Realm. Realm delivers a great set of APIs for its developers. It offers great synchronization also.

2. Firebase

For offline application development, go for Firebase. It is a local database backed by google having NoSQL. It renders great support for offline data synchronization. The key feature is Firebase can be combined with any app easily.

3. Async Storage

It is a React Native in-built database. There is no need for separate deployment for this database. It helps to store data locally and retrieve it between reboots. It can be accessed by the developer whenever it is required.

4. Vasern

Developers always look for faster databases to save their time. For them, Vasern is the suitable one. Like Realm, Vasern is also an open-source local database. It is mainly focused on better performance and better consistency of the application.

5. SQLite

SQLite executes almost all SQL standards. People having amazing database management skills can utilize SQLite for better performance. It is free to use database and it is available in the public domain.

Conclusion

Local Database helps the developer to manage data effectively and efficiently. It also helps in offline app development and offline data synchronization. Developers look for free, easy-to-use databases to complete their work most efficiently in a short period. For React Native the above-said databases are giving great results.
