Realm.io features and specs

  • Easy Integration
    Realm is designed to be easy to set up and integrate into existing projects, with straightforward APIs and comprehensive documentation.
  • Performance
    Realm provides high performance with minimal overhead. It's faster than many traditional databases for many use cases, especially with large datasets and complex queries.
  • Cross-Platform Support
    Realm supports multiple platforms including iOS, Android, and React Native, allowing for easy cross-platform development.
  • Real-Time Data Sync
    Realm offers real-time synchronization of data between devices and a server, ensuring consistency and enabling collaborative features.
  • Rich Data Types
    Realm supports complex data types such as lists and objects, making it more flexible for various types of applications.

Possible disadvantages of Realm.io

  • Learning Curve
    Despite extensive documentation, there can be a learning curve for developers new to Realm, particularly if they are accustomed to traditional SQL databases.
  • Storage Size
    Realm databases can become large quickly, especially if not properly managed, potentially impacting app performance and storage costs.
  • Limited Query Language
    While powerful, Realm's query language isn't as mature or feature-rich as SQL, which might limit some advanced querying needs.
  • Tooling
    The tooling ecosystem for Realm is not as extensive as those for more established databases like SQLite or MongoDB, which could impact developer productivity.
  • Vendor Lock-In
    Using Realm might lead to vendor lock-in, as migrating away from it to another database system can be complex and time-consuming.

Realm React Native features and specs

  • Offline First
    Realm React Native enables offline-first experiences, allowing applications to function without network connectivity by storing data locally on the device.
  • Data Synchronization
    Built-in synchronization with MongoDB Atlas ensures that local data is automatically synchronized with the server, reducing the need for custom sync logic in the app.
  • Performance
    Realm offers high-performance data handling by using a custom database engine that is optimized for mobile devices, allowing quick access to and manipulation of data.
  • Ease of Use
    The API is designed to be intuitive and easy to use, making it accessible for developers to implement database operations without excessive complexity.
  • Real-time Updates
    Provides real-time data updates, ensuring that any changes in the database are immediately reflected in the application UI.

Possible disadvantages of Realm React Native

  • Learning Curve
    Developers new to Realm may face a learning curve compared to more traditional databases, as it introduces unique data models and patterns.
  • Limited Support for Complex Queries
    While Realm supports basic queries efficiently, handling complex queries may be less straightforward than with a traditional relational database.
  • Dependency on Specific Ecosystem
    Using Realm tightly integrates an application with MongoDB's ecosystem, potentially complicating migration to other databases or systems.
  • File Size
    Realm's file size can grow significantly, especially with large datasets, which may be a concern for apps with limited storage space.
  • Open Source Limitations
    Realm is open-source but certain advanced features are tied to MongoDB Atlas, requiring consideration of potential costs and limitations in free-tier usage.

  • Release Radar · September 2024: Major updates from the open source community
    From the team at MongoDB comes Realm, a mobile database that runs directly inside phones, tablets, or wearables. It's built for mobile, and designed for offline use. The latest release comes with built-in Swift 6 language mode, and Xcode 16 support. Some breaking changes include removal of Atlas App Services and Atlas Device Sync functionality, Strings and Data now considered different types and thus queries won't... - Source: dev.to / 7 months ago
  • I built a WebComponents-based framework
    Looks really cool, I like to make very minimalistic dependency choices for the web apps I work on. Web Components look interesting and it's great to see frameworks that build upon it and provide features that are currently missing from it. When I landed on the page I remembered another Realm framework I used a lot long time ago. https://realm.io has the same name and the logo looks very similar too. Not sure if... - Source: Hacker News / over 1 year ago

  • Looking for android java developer mentor
    I would focus on Kotlin instead of Java, there's really no point in sticking to Java at this point. And when it comes to databases, some local ones that are pretty easy to get into are Realm and ObjectBox, SQLite can definitely be a bit overwhelming at the beginning. Source: almost 2 years ago

  • Using Expo and Realm with expo-dev-client
    The Realm React Native SDK has a hermes branch that is indeed compatible with Hermes. So, it'll work with react-native-reanimated v2 but not with Expo, due to the React Native version the Expo SDK is pinned to. - Source: dev.to / about 3 years ago
  • Getting started with Realm for React Native Using Expo Template, Enhanced
    Simple Expo React Native application to quickly get started with React Native RealmDb API, based on the starter template that is provided by Realm. I added a few things, specifically working with relationships in RealmDB since it was really what I was looking for before I started to create the video. - Source: dev.to / about 3 years ago

  • Observing Realm database transactions with React Native
    Realm’s React Native SDK is an incredibly powerful tool that takes advantage of the NoSQL database developed by MongoDB. Realm can be used for offline first mobile apps or as a general purpose database for traditional mobile applications. One of the biggest advantages of using Realm for data storage is that it’s Objects are “live” by default; meaning that transactions and the state associated with a given Object... - Source: dev.to / almost 4 years ago
