The intricacy of your data is a major factor in deciding which React Native app database to use. When evaluating a database, you should also consider its memory management capabilities and how it handles conflicts. You can use a local database or a database on the server. To meet your business needs, such as offering offline functionality or enhancing your app’s scalability, you’ll find information in this blog about the best databases for React Native app development.

1. Realm Databases :

Architecture, native offloading, and databases are just a few things that affect how well React Native apps work. Just have a look at the great things about the Realm database that make it the best choice for a local database out there.

Like traditional databases like SQLite, Realm has a zero-copy design architecture that doesn’t make unnecessary copies of raw data by putting all the data in a single file. Realm does this by simply figuring out the offset, reading data from a memory-mapped area, and then giving back the raw value.

Benefits of Using Realm:

  • A faster way to do queries:

The Realm database stores object files on the disc, making it faster than other local databases for React Native because it can perform data queries even faster than other React Native databases. Also, all of the read and write operations in Realm happen on the main thread without any pause.

  • Multithreading is allowed:

Realm supports multithreading, which means you can have as many threads working on the same thing simultaneously. Realm takes care of this by automatically updating the data on every thread to make transactions go more quickly.

  • Security:

As a React Native app, your data can be encrypted with the help of the Realm database. Realm encrypts and decrypts data with the standard AES-256 encryption method. Every time you want to use the data in your Realm, you first need to encrypt it with a key so that it can’t be read. This is a great security feature that will keep your data safe from being stolen or used.

2. Firebase :

In Firebase’s dynamic non-relational is possible to store unstructured data. React Native local database. React The database’s data synchronization capabilities can support native offline-first apps. Firebase can store a wide variety of storage units because it is extensible. However, unstructured data types like documents and JSON are best suited for this approach.

Firebase is a great option if you want your app easily scalable. It scales horizontally means that you may continue to use your current servers while adding more. Databases with horizontal scalability (e.g., elastic databases) are also called elastic. Elasticity in this context refers to the ability to both remove and create new server objects.

As a product of Google, one of the most powerful modern technology companies globally at the time, Firebase is worth noting. In terms of data management, this company is a pro.

Distinguishing traits:

  • Persistence when not connected to the Internet

Developers can use this capability to create apps that save data locally instead of relying on the Internet. The software will also send all the data to the server whenever a connection is made again. In addition, when an app is disconnected, Firebase saves the user’s progress by the minute.

  • Synchronization in real-time

With Firebase, you can sync data from numerous devices simultaneously, saving you time and effort. Teamwork apps will benefit from this feature because it will provide a copy of your data in a sudden loss of connection.

  • Deployment in a flash

Firebase is more than just a database management system. Server, API, and datastore are all part of the backend service (BaaS). React Native apps benefit greatly from APIs when it comes to database setup. You link your iOS and Android apps to the Firebase server simultaneously during the process.

  • Cross-platform

Firebase is compatible with a wide range of mobile devices. The API makes it possible to manage all threads from a single location.

3. SQLite :

A NoSQL database built around existing storage entities rather than built on top of them is Firebase. This approach of scalability offers the database an enormous potential for expansion. You can also scale out your React Native app while running with Firebase.

Apps can customize the Cloud Firestore Security Rules to suit their requirements. You can think of your security rule patterns as defense’s against malicious queries in your database. Firebase doesn’t need an intermediary service to defend itself from unsolicited queries from clients.

Server-side data protection is lacking and vulnerable to unauthorized access. Firebase doesn’t encrypt the information it stores, to be more exact. That makes it unsuitable for applications that collect and utilize sensitive information (banking apps). Consider databases like Realm, which encrypt their data to protect it from unauthorized access.

SQLite is a relational database management system. SQLite Lite is a lightweight library version of a database that does not require a different setup. Mobile apps can use SQLite to access and manipulate databases natively.

SQLite ACID compliance has the following advantages: an ACID-compliant database that implements SQL standards:

  • Using a plugin, you may access and manage the database from the app.
  • Using SQLite for security
  • The SQLite Encryption Extension (SEE) is available on the company’s official website and allows users to encrypt their data with SQLite.

License fees are necessary to use the extension, but this is a one-time expense. The plugin uses various encryption techniques to prevent unauthorized access to the data during reading and writing activities.

Besides SEE, there are several alternative SQLite implementations:

  • X SQLite is a C++ library that wraps SQLite data in encryption.
  • 256-bit AES encryption is supported by SQLCipher, an open-source plugin that uses OpenSSL’s libcrypto API.
  • Custom API-based encryption can be implemented using SQLite Crypt.
  • SQLite improves the performance of React Native apps

SQLite can answer queries in milliseconds. By reducing disc access. SQLite information processing knowledge is required, and the ability to identify and measure the processes that take up the most time to perform operations and queries.

It is possible to speed up the insert, update, and delete operations in SQLite using the Begin and End operators instead of many DML code statements. 

SQLite ACID compliance has the following advantages: an ACID-compliant database that implements SQL standards. However, there are substantial omissions. Having these four pillars in place ensures the integrity of database information, even if one or more of them goes wrong. SQLite features a file-based design that makes it easy to use when handling various kinds of data.

Using PRAGMA instructions, it’s possible to enable SQLite’s offline persistence mode.

4. PouchDB :

As long as you have a JSON-encoded database, you can query and modify the data using the easy JS API.

While offline, PouchDB may save data locally and sync it with compatible servers and CouchDB when the app is back online, keeping all user data synchronized. PouchDB is a small and lightweight requirement.

It makes it simple for a React Native app to protect its users’ data. Passwords are stored in the short form with the PBKDF2 crypto algorithm to protect encrypted keys from degraded attacks in React Native’s built-in authentication mechanism.

What You Get from Using PouchDB:

  • Any compatible server can be synchronized using this tool.
  • PouchDB is a CouchDB-based database that can be used both online and offline.
  • Because SSL is supported, AES256 encryption is no problem.
  • It aids in the replication of data like a pro.
