Through the execution of this command, the user will be able to create the folder with my first react native application automatically on the system. Also there will be installation of all the needed packages.
Step 2
Overviewing of default react native application structure
Once the installation of the project files is completed then, the project structure will appear as mentioned below:
First, new create react native app then it appears like this
Now let’s try to have an understanding of the basic utilization of the files as well as the folders that are listed below:
Node_ Modules
This is a folder which is having all the craft create react native app and the installation of this is dependency-related code. There will not be any requirement for assessing the folder.
package.json
This is another file that is set up by NPM. It is comprised of all the metadata and dependencies along with the script for your mobile application. Other crucial things that are listed in the package are dependencies. The dependencies will be acting as the modules/ packages which are utilized within the mobile application.
gitignore
This is a file that is communicating with Git for monitoring some specific files as well as folders. There is no need for any extensive folder like the node_ modules folder.
The output about App.js file
This serves as the initial point of the start of the application. The main component which is initiating the whole app
Step 3
Overview of customized React native mobile app structure
This is another new project structure to create React native app
Assets
The assets folder will enclose the images, vectors, fonts, and other things
src
It is this folder that is the main component of the whole of the code within the app. This folder is comprised of the source code along with all the React native-related code. The developer will be working mostly on this while starting on their react native project
Components
There are folders for storing any common component which are utilized in the mobile application
config
Folders for storing API config, and notification configuration which is utilized in the application
Navigation
It comprises the folder for storing any kind of navigator
Constants
This is another kind of folder which is used for storing constant utilized to react native create app
Redux
This is a folder for storing the whole of the screens/ features in the mobile apps
Screens

npx react-native run-ios
In the case of using yarn
yarn run ios
yarn ios
The above-mentioned commands will create your mobile app and launching the same on the specified platform
Step 5
Make changes to your mobile app
The developers intend to modify the code to improve react native performance. Now when the project is being developed, the developer can start introducing changes in their application. So for that, you have to open the directory of the project in the preferred code editor and carry out the modification of the source code file for creating the desired app.
Step 6
React Native Debugging
Using statements console.log()
This is one of the convenient tactics for debugging a React native application. This is through the use of the statement
console.log(). There can also be the addition of the console.log() statements to the code to output variables/ objects along with other types of data to the console. This will assist in identifying the issues within the code.
Using chrome debugger
The React native framework also provides the option of Chrome debugger and this is utilised for debugging the mobile app. For utilising this Chrome debugger, the user is required to open the app on their Android/ emulator while shaking the device to open the developer menu. After that they are required to select the debug with Chrome. This will open a new tab within Chrome and facilitate you to debug the mobile app by utilising the Chrome Developer tools.
By using the above-mentioned tools, techniques, and commands, there will be the identification as well as fixing of all the issues in your mobile app and you will be able to formulate a high-quality application for the end user.
