When building extensions, it’s important to perform tests on a real device and not just a simulator as real apps are likely to exceed the memory limits of an app thus resulting in memory leaks (which we’ll discuss later in this article). A great example of an extension that fixes the single-threaded issue is one that creates a bridge between React Native and Native components. Extensions can be built using either Java, Swift, or Objective-C. An extension lets you provide an app with custom functionality that it would otherwise not have. The fix to single-threaded limitations in an app is for engineers to build maintainable extensions that can handle multithreading in a React Native app. High-end devices with more RAM and processing power may get along fine but cheaper devices wouldn’t be able to run apps like Mixer as shown below: Screenshot taken from Mixer, a live stream gaming app This proves to be a huge challenge for apps that may want to implement multiple features simultaneously such as a streaming service that needs a live chat feature alongside a live stream feed. In its rendering process, rather than have multiple processes occur at the same time (multithreading), other components have to wait when one component is being rendered. React Native is single-threaded in nature. However, this doesn’t prevent a couple of performance issues from springing up from time to time, let’s highlight these issues and how we can fix them. It’s important to keep passes between both sides of the bridge to a bare minimum to avoid any kind of performance-related issues.īecause React has a virtual DOM, it renders JavaScript components asynchronously and in this process, reduces the amount of data that needs to be sent over the bridge. Say you are passing huge files between both threads, this could slow down performance. Now, the UI and JavaScript threads are individually fast but where performance issues occur is during the communication between both of them via the bridge.

An application’s logic – including which Views to display and in what manner they are displayed - is usually configured here

The UI thread - this is the native thread used to run Swift/Objective C in iOS devices and Java/Kotlin in Android devices, an application’s UI is manipulated solely on this thread.There are three threads that mainly run a React Native app: To understand the problem, let’s first take a look at how React Native’s architecture works. React Native’s architecture – how it all works In this blog post, we’ll take a look at certain features that limit React Native’s performance and how we can reduce their effects to build robust products with this framework. Unfortunately, developers face certain hurdles related to performance when working with React Native.Įvery framework has its limitations, what matters is how we work around them and build fully functional applications.
