The newest 0.70 version of React Native is here with some smashing improvements and brand-new infrastructure that is again stealing attention away from the other <\/span>cross-platform apps <\/b>framework. From integrating a new unified configuration for Codegen to establishing Hermes as the default engine, this new 0.70 has a lot for developers and businesses looking to hire <\/span>React Native App Development Company<\/b><\/a> for their project.\u00a0<\/span><\/p>\n

Know about this latest release, the process of upgrading, and why it matters to <\/span>mobile app developers <\/b>in the following blog below. Let\u2019s dig right away!\u00a0<\/span><\/p>\n

<\/span>React Native 0.70\u2013 Introduction<\/span><\/span><\/h1>\n

Since the day of React Native\u2019s derivative release, the framework is seen to keep on improvising while coming up with new ideas and upgrades to enable developers with compatibility and stability to create and deploy an application seamlessly.\u00a0<\/span><\/p>\n

React Native 0.70 version is just the perfect example of this!\u00a0<\/span><\/p>\n

\"React<\/p>\n

As per experts, it is the most stable version that will be used automatically whenever a new project is created using the<\/span> npx react_native init<\/span> command.\u00a0<\/span><\/p>\n

<\/span>Important Updates for the New React Native Architecture<\/span><\/span><\/h3>\n

The main focus of React Native 0.70 is enhanced support for the new architecture, even if there aren’t many notable new end user features. The new architecture has been in development for a while and has been gradually implemented through a number of <\/span>React Native development versions. It’s wonderful to notice that more and more new versions have it activated by default!<\/span><\/p>\n

The new architectural work intrigues and impresses the <\/span>mobile app developers<\/b> at personal grounds, especially in light of some of the performance complaints made against earlier iterations of React Native. In the new architectural design, the React Native team has directly addressed these issues. This gives developers the confidence of creating a seamless platform even in 2022, RN will be a wonderful option for <\/span>cross-platform app development<\/b><\/a>.<\/span><\/p>\n

Let\u2019s know what\u2019s in the new upgrades of <\/span>React Native app development<\/b>.\u00a0<\/span><\/p>\n

<\/span>What\u2019s New: Hermes JavaScript Engine as Default\u00a0<\/span><\/span><\/h2>\n

Hermes is a powerful JavaScript engine designed specifically for React Native. Although it has long been accessible, it was once an add-on that required installation and configuration separately when creating a<\/span> React Native services<\/b> project. Hermes was packaged with React Native beginning with version 0.69, making it easy to activate and use while also making it easier to stay in line with the rest of the framework.<\/span><\/p>\n

\"Hermes<\/p>\n

 <\/p>\n

Hermes is the default JavaScript engine as of the most recent release, 0.70, therefore no further installation or configuration is required to utilize Hermes when starting a new project.<\/span><\/p>\n

<\/span>Why it matters:\u00a0<\/span><\/span><\/h4>\n

The Hermes engine on each platform offers much-improved speed and memory use than the native JavaScript engines. Many apps were not using the engine since it had to be installed and set up separately in the past.<\/span><\/p>\n

Although Hermes has been there for a while, the 0.70 release will really provide<\/span> React Native apps<\/span><\/a> a significant speed gain by making it the default setting. It is well worth the effort to have Hermes enabled and enjoy the performance advantages if you already have an app but haven’t yet activated it.<\/span><\/p>\n

<\/span>What\u2019s New: Build Improvements & Cross-platform Consistency\u00a0<\/span><\/span><\/h2>\n

A number of improvements that enhance the React Native build and development process are also included in version 0.70, especially when working with the new architecture.<\/span><\/p>\n

<\/span>1. Auto-linking for New Architecture libraries on Android<\/span><\/span><\/h3>\n

An essential step in the <\/span>React Native development <\/b>process is auto-linking. It enables us to use a package management like yarn or npm to integrate native code into projects using JavaScript modules. New architectural libraries needed manual linking on Android before to this release, but as of 0.70, both iOS and Android fully support auto-linking.<\/span><\/p>\n

<\/span>2. Full CMake Support for Android Builds<\/span><\/span><\/h3>\n

\"CMake<\/p>\n

 <\/p>\n

Instead than depending on the less popular NDK build system, the new version offers complete CMake support for Android builds. Better support, fewer configuration files that are simpler to maintain and upgrade, and integration with a more developed CMake ecosystem are all benefits of this.<\/span><\/p>\n

Users of apps and libraries on the New Architecture will benefit from this upgrade because:<\/span><\/p>\n
