Databases for react native

Best Databases for React Native App Development

React Native is the best network for building a cross-platform mobile app for iOS and Android. React Native development is becoming more popular, and many companies and developers rely on this framework and also its ecosystem to create mobile apps.Choosing a database for your app is a common difficulty during React Native development. A number of database options are available. The following is a list of database options discussed in this blog.

• Firebase 
• Realm Database
• SQLite

Firebase and Cloud Firestore

Firebase is a Backend as a Service that aids in the creation of well-designed APIs while keeping the tech stack to a minimum. In terms of architecture, applications are frequently complex. They're usually built as a full-stack application, which combines a frontend and a backend with a database.

Using Firebase, you can design your mobile app without having to spend a lot of effort setting up a bespoke server that can securely communicate with a database. It has a Firestore database, which is a NoSQL database. The data is synchronized with total clients in real-time, which is an essential feature of using Firebase. Firebase provides techniques for listening to real-time subscriptions that you can use. When you use Firebase, it's very simple to get started. It requires very little work, and Firebase provides a wonderful dashboard for controlling database aspects and setting your own security rules. There is no steep learning curve because the Firestore database is built on NoSQL vocabulary, and the basic notions of that terminology, such as storing data in collections and documents, apply here as well. Firebase also has persistent features for tracking a user's offline and online presence. When a user disconnects from their network, it saves a timestamp.

RealmDB

MongoDB or Realm database Realm (which was recently acquired by MongoDB) is a React Native data engine that can handle enormous amounts of data. It was created from the ground up to allow developers to construct mobile apps with offline capabilities. It also supports tablets and wearables in addition to mobile applications. Realm provides a comprehensive API for storing, interacting with, creating, and retrieving data. It allows you to use main and foreign keys to construct relationships between distinct rows of data. One of the primary distinctions between a Realm Database and a SQLite database is that it is based on object-oriented concepts rather than typical relational databases. Data is immediately accessible as objects, which may be queried with code, obviating the need for performance and maintenance-heavy ORMs. It also supports generics and vectorization.

For security reasons, Realm uses various encryption standards for each mobile platform. All data stored locally on Android is encrypted and decrypted using the AES-256 algorithm. The encryption for iOS apps is based on the iOS CommonCrypto library, which protects app data as well as passwords stored in the keychain. Realm is an open-source database that is free to use. It includes a developer tool called Realm Studio, which allows you to manage database fields within a Realm database. You may open and update local and synchronized Realms, as well as administrate any Realm Object Server instance, with Realm Studio. You can log in to your instance, browse data, and look at logs, among other things. This development tool is compatible with all major operating systems.

SQLite

In React Native apps, SQLite is a popular method for storing and persisting data locally. It was created with the intention of providing local storage for mobile apps. It provides a lightweight library based on relational databases that are simple to integrate. SQLite is stated to be ACID compliant since it adheres to SQL-based standards. ACID (atomicity, consistency, isolation, and durability) is a set of database transaction qualities designed to ensure transaction validity even in the face of mistakes, power outages, and other issues. There is a package that operates as a native plugin for React Native apps on both iOS and Android platforms that allows data to be saved for offline use. React-native-SQLite-storage is the name of this plugin. Native data persistence features for iOS and Android are available as JavaScript APIs with this package.SQLite doesn't support encryption out of the box, which is a security flaw. On the official website, however, there is an addition called SQLite Encryption Extension (or SEE). This plugin enables SQLite to read and write data in an encrypted format using AES-128, AES-256, RC4, and other algorithms. Other extensions, such as SQLCipher, SQLiteCrypt, and others, can be used to encrypt data when using the SQLite database in React Native apps in addition to SEE.
