The popularity of React Native (RN) as the best option for creating mobile applications is growing. RN is being used by companies and developers to deliver high-performance apps. Teams and developers are continuously under pressure to produce high-performing, offline apps. Selecting the proper technological stack and tools for your projects, especially the suitable database, can be difficult at times.
Let us delve into each factor in details:
Things to Consider When Selecting a Database for React Native App Development
Memory Management
Improper management of mobile app data increases the possibility of app crashes and yet most databases delete their cache after a certain amount of time to guarantee memory availability for ideal app performance.
Ease of Use
Choosing a RN database that requires little integration work is essential. This can help you expedite the development process and greatly simplify the work of the developers.
Concurrency
Users will make several requests, and it will get quite challenging to give them the exact amount of information they need. As a result, you need to fully comprehend the concurrency strategy employed by the different RN local databases before deciding which one is ideal for you.
Complexity of Data
Most apps use JSON structures or key-value storage for their data. Therefore, it’s essential to choose a database that can manage intricate data structures like objects or whole texts.
Offline Data Synchronization
Consumers are always searching for programmes that they can use while their internet connection is weak or offline. Integrating data that permits synchronisation after connecting to the internet has therefore become crucial.
Data Conflicts
Data conflicts can arise while adding new features, therefore it’s ideal to use a database for your React project that has conflict management policies in place.
Leading Local Databases for React Native Development
-
Realm for React Native
Realm is a database whose architecture is object-oriented. Unlike normal relational or SQL databases, the object-oriented paradigm makes it 10x quicker and eliminates the need for you to execute millions of queries.
Benefits:
- It’s simple to use and app development is 10 times quicker than using SQLite.
- It is renowned for creating superior applications.
- All Realm-related documentation are written accurately, and developers may locate the answers they need on the official website.
- It experiences lower latency and server expenses, is offline friendly with Redux and is best for producing and saving data on the go.
Drawbacks:
- The size of the APK grows and make use of RAM increases.
- Values cannot be automatically increased.
- Multiple processes cannot simultaneously access the database.
-
SQLITE for React Native
SQLite was developed to give local storage databases for RN apps running on mobile devices. Developers often utilise SQLite storage with RN. The term “Lite” indicates the library is lightweight and requires minimal setup. For immediate database access, it may also be directly incorporated into the mobile application.
Benefits:
- Data may be saved in the cross-platform database file using SQLite.
- It is easy to use, affordable, portable and it is pre-installed on both Android and iOS with TCL integration support.
- SQLite databases are easier to restore in the event of a loss and support all SQL standards.
Drawbacks:
- The maximum size for SQLite can be up to 2GB in various circumstances and database size it supports is 140 TB.
- It manages low to medium flow HTTP requests.
- It does not provide access to multi-client concurrency.
-
Firebase for React Native
One of the greatest databases for RN is Firebase. It offers real-time NoSQL databases for the creation apps. Its offline data change and synchronisation features are the main reasons it was selected. Because it can handle both the M and C of the MVC requirements for RN based applications.
Benefits:
- Real-time data synchronization: Firebase for React Native enables simultaneous real-time data synchronization for all clients. This is crucial when an app abruptly disconnects from the internet.
- Firebase’s cross-platform API takes very low setup effort.
- Real-time apps with offline persistence may be made by developers using Firebase and RN together.
Drawbacks:
- It provides restricted assistance with iOS features.
- It is inoperable in nations where Google is prohibited. Issues with data migration and real-time synchronisation are caused by Firebase.
- Because you must use a single vendor, you are unable to estimate its price. It is not possible to query for more than one key at once in Firebase.
-
Watermelon DB for React Native
Watermelon DB is an innovative way to manage user data in RN and React online applications. Real-world performance is the focus of its design, which is for complex RN apps. In other words, your programme needs to start up fast. Because of its database-neutral nature, Watermelon DB may be utilized on a variety of systems. Depending on the needs of the platform, this high-level data management layer may link to any react-native database layer.
Benefits:
- Lazy loading: Watermelon Database uses lazy techniques to manage data persistence on low-end devices. Because of this, the programme won’t load any requests unless they are initially requested.
- Speed: Real-world speed is the primary objective, and it is optimised for creating intricate apps in RN. Put another way, your app must open quickly.
- Reactive nature: Watermelon DB is completely observable, in contrast to SQLite. Therefore, any UI elements that rely on a record will immediately re-render if that record is changed.
Drawbacks:
- Developers must build their backend (which requires them to implement a rest API and handle authentication) to synchronise data.
-
Pouch DB for React Native
Based on Apache CouchDB, Pouch DB is an open-source JavaScript database designed with browser compatibility in mind. To guarantee that user data is always current, it enables apps to store data locally when they are offline and synchronise it with CouchDB. When connected to the internet, it synchronises locally stored data with CouchDB and the servers to enable offline operation. To store data locally, it makes advantage of the browser’s Web SQL and Indexed DB.
Benefits:
- Data sync: Pouch DB may also be used to synchronise data amongst various users, which resolves data conflict issues.
- Pouch DB offers data replication, enabling the detachment of local storage from the server side while both copies are being updated simultaneously. After the update is finished, there is no data leakage as the data is synchronised across several clients.
Drawbacks:
- In the case of a large database, it is rather weak.
Conclusion
The performance, security, and scalability levels must all be considered when selecting the best database for your React Native applications.
Every database has a unique collection of important characteristics, advantages, and disadvantages. Comparing them would be unfair because each one is distinct!
