Essential Tips and Tricks for How to Use React Native Effectively

1

React Native enables hire the best react native developer to build mobile apps for both Android and iOS at once. For this reason, it can lead to some confusion as to how best to use React Native.

1. Adjust your expectations about performance React Native apps cannot match their native counterparts in terms of pure speed or number of animations they can perform. This is because React Native does not have direct access to anything that runs code on a phone's CPU or GPU from JavaScript code.

As such, things like complex calculations or any sort of rendering algorithms tend take more time in React Native than in an actual app built with Java or Objective-C. Because of this, make sure you only compare things like how fast data is refreshed, or how smooth the user experience is between both apps.

2. Remember that React Native has a 'native' API too There are two API's in React Native – one for JavaScript and another one specific to Android and iOS. This means if there is a feature you want your app to have which is available natively on Android or iOS but not yet implemented in React Native, consider checking if it already exists as part of its native API first. If so, you can use this API from your own JS code instead of trying to hack around with React Native methods. In this way, you can sometimes avoid having to use platform-specific implementations for features that do not exist in React Native's API.

3. Know the libraries to use React Native ships with a set of its own commonjs modules to help you develop apps in it. These are served from static node_modules directories which are not versioncontrolled with your code. As such, they cannot be depended upon by other people who work on the project or when trying to integrate React Native into existing projects that already have their own external dependencies and tooling (such as npm). If you want to use third party JavaScript libraries like jQuery or lodash, consider using npm instead. This is a command line tool that can transpile Javascript modules into built JS files for both iOS and Android appropriate for inclusion in your app's codebase (make sure you indicate on your package.json file what target this dependency is meant for, otherwise it will be built for both). When using rnpm , bear in mind that there are some popular libraries which are not yet compatible with React Native (like momentjs).

4. Familiarize yourself with all of React Native's configurations React Native has a number of configurations available to change how an app behaves when running the JavaScript code inside the Simulator or on actual Android and iOS devices. To access these settings, open up your project's ios/android folder and take a look at the index.* files. These let you turn off debugging information (used when running from Xcode or Android Studio), change which js bundle file should be loaded when running on a device, and change which hire react native developer certificate to use in order to access the desired platform. There are other configurations you can add as well such as feature flags, but we will cover them later in this article.

5. Know the difference between JavaScript iOS modules and native iOS modules One of React Native's features is that it lets you seamlessly call out to custom Objective-C code from your Javascript code. If you want to do this in your app, consider looking through its ios/ directory for files with js* or native* prefixes. The former group are plain Javascript files which contain functions that return objects after being wrapped by an NSObject layer – these objects have to be turned into proper Cocoa Touch classes before they can be used to write native iOS modules.

6. Consider keeping your original app around for testing purposes This might not necessary for each project, but if you need to do testing of things like making sure that an animation does not break or that an API works as intended under different conditions, it is best practice to keep the original app around and running on a device while developing it to compare its behavior with whatever changes you have made along the way.

Conclusion React Native is a mobile app development framework that allows you to build iOS and Android apps using the same approach and tools. This makes it easier to hire react native developer to get into mobile app development with their Javascript skillset. It also means that hire react native developer can create cross-platform mobile apps more efficiently than before, allowing them to spend more time focusing on business logic rather than learning new languages or reworking their codebase for different platforms.
