Kotlin Multiplatform (KMP) VS Compose Multiplatform - Explained

Summary

The video discusses two popular concepts in software development: Kotlin Multi-Platform and Compose Multi-Platform. Kotlin Multi-Platform allows developers to share business logic across various platforms like Android, iOS, and web, though it is still in an unstable phase. It requires the use of specific multi-platform libraries for shared functionality. In contrast, Compose Multi-Platform builds on Kotlin Multi-Platform, enabling UI sharing as well, although it is currently in Alpha for iOS and experimental for web. This technology aims to streamline cross-platform app development, enhancing efficiency and code reusability.

Takeaways

• 🌟 Kotlin Multi-Platform allows developers to write code once and share it across multiple platforms, including Android, iOS, web, and desktop.
• 📱 The primary goal of Kotlin Multi-Platform is to simplify the development process by using a single programming language for different environments.
• 🛠️ Multi-platform libraries are essential for sharing functionality across platforms; examples include Ktor, KSerialization, Kotlinx.datetime, SQLDelight, and Coroutines.
• 🔍 Kotlin Multi-Platform is currently not stable but is expected to become stable soon, making it a good time to get acquainted with it.
• 💻 Developers can create business logic that is platform-agnostic, allowing for more efficient coding practices.
• 🎨 Compose Multi-Platform extends Kotlin Multi-Platform by enabling UI component sharing across different platforms.
• ⚙️ Compose for iOS is currently in Alpha, while Compose for web is still in the experimental phase, indicating ongoing development.
• 📈 The integration of Kotlin Multi-Platform and Compose Multi-Platform enhances productivity by reducing the amount of platform-specific code needed.
• 📝 It is crucial to look for multi-platform libraries to maximize the benefits of Kotlin Multi-Platform in your projects.
• 👍 Encouragement to like, share, and subscribe for more informative content related to Kotlin and its technologies.

Q & A

What is Kotlin Multi-platform?

Kotlin Multi-platform is a technology that allows developers to use a single programming language to build applications across different platforms, including Android, iOS, web (both front-end and back-end), and desktop.

What is the primary goal of Kotlin Multi-platform?

The primary goal of Kotlin Multi-platform is to enable code sharing, allowing developers to write the business logic once and share it across multiple platforms.

Is Kotlin Multi-platform stable at the time of the video recording?

No, Kotlin Multi-platform is not yet stable at the time of the recording, but it is expected to stabilize soon.

What do developers need to consider when using libraries in Kotlin Multi-platform projects?

Developers need to search specifically for multi-platform libraries to use functionality that can be shared across all platforms; otherwise, they won't be able to share library code across different platforms.

Can you name some multi-platform libraries mentioned in the video?

Some multi-platform libraries mentioned include kotlinx.serialization, kotlinx.datetime, SQLDelight, and Koin coroutines.

What is Compose Multi-platform?

Compose Multi-platform is built on top of Kotlin Multi-platform and focuses on allowing developers to share the user interface (UI) between different platforms, in addition to sharing business logic.

Is Compose for iOS stable at the time of the video?

No, Compose for iOS is still in the Alpha stage at the time of the recording.

What phase is Compose for web in at the time of the video?

Compose for web is in an experimental phase at the time of the recording.

What advantage does Compose Multi-platform provide compared to Kotlin Multi-platform?

Compose Multi-platform provides the advantage of sharing not just the business logic but also the user interface across platforms, enhancing code reuse and consistency.

Where can viewers find more information about building a Kotlin Multi-platform application?
