Why Do You Need to Be Careful While Selecting the Right Database for React Native?
A developer is under a lot of stress to create an app that can be modified at any time. As a result, it might be challenging for developers to choose the correct technology stack for React Native that includes the right database.
In coding, data is of utmost importance, and it is saved in variables if it isn’t a large program. When a program or software is restarted, the data is set to its original value, which is a huge disadvantage as this can result in the loss of data. In this regard, the database plays a vital part in keeping data stored and allowing us to retrieve it even after restarting. Async Storage, SQLite, Realm, PouchDB, and more databases are available for usage in react native apps.
What Are the Different React Native Databases Available for Use?
1. MMKV Storage
MMKV storage allows you to save data in a React Native application quickly. Everything is developed in C++, so it’s quick and efficient. Another benefit? The library is basic and light (50K Android/30K iOS), and it shrinks, even more, when packed. MMKV also supports redux-persist and allows you to save any form of data with or without encryption.
- Encryption support (secure storage)
- Multiple instances support (separate user data with global data)
- Customize storage location
- High performance because everything is written in C++
- ~30x faster than AsyncStorage
- Uses JSI instead of the “old” Bridge
- iOS, Android, and Web support
- Easy to use React Hooks API
2. Realm Database
Realm is faster than even raw SQLite on common operations and has an extremely rich feature set. Realm is a lightweight database in Android, but it doesn’t use SQLite. Realm uses very less memory in comparison to SQLite. Realm is very fast in reading & writing data compared to SQLite.
- As Realm is an object store, relationships between objects are allowed via “links.”
- Each “link” creates a “backlink” as an inverse relationship to whichever objects are linking to the current object.
- Realm can update its instance version.
- Realm has “zero-copy architecture” (along with the previously mentioned lazy-loaded data access).
In mobile applications, SQLite, a C-language library, is used as the datastore. SQLite is particularly useful for offline applications, and many platforms come with SQLite support out of the box, making it simple to set up. One of the most well-known free Android development databases is this one. Its most distinguishing feature is that it is open-source, making it extremely adaptable to any developer’s project and demands.
- In both Java and Native modes, Android can be used.
- Importing a pre-populated SQLite database from the app package and sandbox
- Callback API is supported on Windows, just like it is on iOS and Android.
The Firebase Realtime Database is a cloud-based NoSQL database that allows you to store and sync data in real-time amongst your users. Google Firebase is a Google-backed app development platform that allows developers to create apps for iOS, Android, and the web. Firebase delivers analytics tracking, reporting, and app issue fixes, as well as marketing and product experimentation capabilities.
- Data is synced across all clients in real-time and remains available even when an app goes offline.
- Firebase frees developers to focus on crafting fantastic user experiences. You don’t need to manage servers.
- You don’t need to write APIs. Firebase is your server, your API, and your datastore, all written so generically that you can modify it to suit most needs.
- Firebase caters to a cloud-hosted database in which the data is stored as JSON and further synchronized constantly to each associated client.
- The cloud-based database can be leveraged for managing the app’s data and providing swift data outcomes.
5. Watermelon DB
In React Native and React online projects, WatermelonDB is a novel means of managing user data. It’s designed for creating complicated React Native applications, with real-world performance as the top priority. Simply said, your software must launch quickly. Watermelon’s architecture is database-agnostic, allowing it to be used across multiple platforms. It’s a high-level data management layer that can connect to any react-native database layer, based on platform requirements.
- Watermelon DB uses lazy loading, which means it only loads data when it is requested, making your application highly scalable.
- Even with 10,000 records, most queries take less than 1 millisecond to complete since all querying is done on a different thread on the SQLite database.
- Regardless of how much data you have, you can launch your app right away.
- It’s compatible with iOS, Android, and the web.
- It’s quick, asynchronous, multi-threaded, and cached to a high degree. It’s made to work with a synchronization engine to keep a react native local database in sync with a distant database.
- PouchDB can be used in a variety of browsers because the API it provides is the same in all of them.
- PouchDB is simple to learn and understand if you have a basic understanding of programming languages.
- As a lightweight API, we can easily incorporate it using the script tag.
Vasern is a React Native data storage system based on linked-consistent key-value stores. Its data engine is created from the ground up to provide native performance. Our goal is to provide an end-to-end database system that is open source and developer-friendly.
- UTF-8 encoding is used for support languages.
- Basic data types are supported (string, int, double, DateTime, and reference)
- Make a schema. Records can be created, updated, queried, and deleted.
8. Small Organizations Also Use Server-Side Databases for React Native App Development Like MySQL, MongoDB, and DynamoDB
What Are the Most Important Factors That All Developers Need to Consider Before Selecting a Database?
Ensure that enough memory is available in the database for the software to execute properly. Choose a database that can handle complex data structures such as entire documents or objects. When users reconnect to the internet, it’s critical to integrate the database that allows data synchronization. Go for a database that can be combined with a minimum of effort.
When looking for the correct database for your React Native app, your developers should be very clear about all of your requirements. Realm performs admirably as a local database, regardless of the developer’s needs. SQLite does not give the same degree of security, efficiency, or flexibility that realm offers. Furthermore, while Firebase is well-founded and well-suited for constructing real-time applications, if you have a larger strategy and concept, Realm or SQLite are better choices.
Each database has its own set of key benefits, features, and drawbacks. It would be unfair to compare them because they are all unique! The goal is to examine your project’s goals, create a list of databases, study them in-depth, and choose the best one that meets your needs.
