In WatermelonDB, the UI is automatically re-rendered when any changes are created in the database. This database offers offline synchronization by syncing engines. WatermelonDB is known for its speed and hence applications are loaded instantly irrespective of the data size.
You can use other local databases such as Realm or combination with any other server-side database to store your sensitive data with encryption. However, if you somehow wish to use the same for these apps you need to make sure your data remains encrypted and also your encrypted key doesn’t remain in that database itself. Offline-persistence – Firebase give developers liberty to build real-time applications with additional offline persistent capabilities. This includes marking an user presence as offline/online and storing a timestamp when a user gets disconnected with network every time. No matter what type of mobile connection you have, there will be latency that will affect the user experience.
Async Storage Class for React Native
Firebase offers a free plan that provides up to 1GB of data storage. However, it also offers additional storage at a minimal price of USD 0.18 per GB as well as a pay-as-you-go plan. However, if you wish to use the Firebase database, you need to make sure that your data remains encrypted and that encryption keys and secrets are not stored in the database itself. We can register and log in, but we also need to log out of our app.
Though DynamoDB can be used at a lower scale it’s often a matter of challenge with a large amount of data. But, when your data is unstructured and complex or when you can’t accurately define your schemas, MongoDB would be the better choice. MongoDB will meet all your challenges with their document-based data modeling. DynamoDB is made completely decentralized with minimal administration needs. It is cost effective database with horizontal scaling, so you need to only pay for the storage and your IO throughput while using DynamoDB. There are some cases where it has been easily reported to store about 50 million records.

Realm also offers storage architecture by using B+ trees to organize objects. The performance is ensured as the Realm database can handle huge data loads. Realm has excellent concurrency control since it’s built from the ground up in C++.
With magnificent built-in analytics, Firebase can go for unlimited reporting up to 500 distinct events . The database size limitation of up to 2GB in most cases is a con. Varied processes can be joined with the application file and can function without interference. This is a self-contained platform since it’s free from all external discrepancies. It’s open-source and designed for online as well as offline use. If you haven’t done yet, you should start learning about RxDB with the Quickstart Tutorial.
Node.js server-side authentication: Tokens vs. JWT
Moreover, when an app becomes popular, the developers need to be more cautious, since it brings in a vast amount of data. For native mobile app development, the only choice for app developers is React Native. It beats all the platforms in the market and in a short period, this framework has managed to win millions of hearts with its awesome features, performance, and ease to use. PouchDB is a JavaScript NoSQL database that follows the API of the Apache CouchDB server database. The core feature of PouchDB is the ability to do a two-way replication with any CouchDB compliant endpoint. While PouchDB is pretty mature, it has some drawbacks that makes blocks it from being used in a client-side React Native application.
This course will teach you how to use Expo along with React Native to create a complete mobile app that runs on both an iPhone and an Android phone. Build and deploy a React Native application quickly using an Expo template application with @realm/react. Use Device Sync to keep data in sync with your MongoDB Atlas cluster and other clients. So now our code is ready where you can do a simple navigation from Register page to Profile page using react navigation package. But you can customize it for your own needs and it also provides some of best advance features.
Benefits of PouchDB
The objects stored in Realm can be accessed concurrently from multiple threads or sources, and it doesn’t require any specific lock configuration. The first two methods we’ll cover both use Redux to handle local-first functionality. This makes sense if all the parts of your app use Redux and react native app development it connects to remote services to save data. You won’t have to write synchronization methods or ensure that your local database is the same type as your remote database. When your data is unstructured and complex or when you cannot accurately specify schemas, MongoDB is the best choice.
SQLite can be integrated with the mobile application to directly access the database. SQLite is a relational database management system developed as a storage solution for mobile applications. The word “lite” refers to SQLite being a lightweight library version of a database with minimal setup required. SQLite can be integrated with mobile apps to directly access and perform database operations. It’s a local storage framework that enables developers to store data locally and retrieve it between reboots of an application.
The story of React Native
You can do this in various ways, but let’s look at why we would want to make use of an offline-first app. MySQL is designed to store large amounts of data and over 100 million records. It also has the capability to support up to 64 indexes per table in the database. Each of the table’s indexes may incorporate anywhere between 1 and 16 columns. MySQL is a popular SQL-based relational database management system. It is released under an open-source license and is developed, distributed and supported by Oracle Corporation.
- The objects stored in Realm can be accessed concurrently from multiple threads or sources, and it doesn’t require any specific lock configuration.
- Built with thin layers and zero dependencies, this database offers simple APIs.
- Since the idea behind the development of React was to provide a user interface, there was something needed to support and made it fully functional at the backend.
- In this post we’ll build, step by step, a simple React Native Mobile App for iOS and Android using Expo and Realm React Native.
- PouchDB best practices include defining proper access-control rules, not storing passwords in memory, and encrypting communications with multiple encryptions.
It is hosted on SSL which keeps the connection safe with the client. Since the idea behind the development of React was to provide a user interface, there was something needed to support and made it fully https://www.globalcloudteam.com/ functional at the backend. Simform pairs human-centric design thinking methodologies with industry-led tech expertise to transform user journeys and create incredible digital experience designs.
Top Local Databases for React Native App Development
Add a feature to the template app by using Triggers and Atlas Search. Join the MongoDB Community forum to learn from other MongoDB developers and technical experts. Don’t forget to add showImportantOnly to the list of dependencies in the second argument of useEffect. Now that the package is fully installed, let’s update the new to-do creation prompt component to use the picker. The root component of the app, which we wrap with the Realm hook providers from RealmContext.ts.
