Welcome guys, In this article, We will learn how to install and setup React Native on Ubuntu. You will have to follow all the below step one by one. I assure you the end of this article you feel happy and save a lot of time.
I’m assuming you are using Ubuntu machine and you have admin access. Let go head with below step.
1. Install Node.JS and npm
Firstly, We have to install Node.JS and npm for React Native mobile app development. Let’s move to terminal.
1.1 Update apt package manager
sudo apt update
1.2 Install nodejs using apt package manager. just run below command
sudo apt install nodejs npm
1.3 Verify nodejs installation or you can say check nodejs version using this command
1.4 Now install npm
sudo apt install npm
1.5 Verify the installation
npm --version or npm -v
2. Furthermore, Install React Native CLI
For installing React Native CLI run below command on terminal
npm install -g react-native-cli
If you get an error like Cannot find module ‘npmlog’ you can install npm directly using this command. If the above command run successfully then no need to run this command
curl -0 -L https://npmjs.org/install.sh | sudo sh
3. Install Java Development Kit
To install JDK 8, follow the below steps
3.1 First, We have to add Oracle’s PPA
sudo add-apt-repository ppa:webupd8team/java
3.2 Now update your package repository.
sudo apt update
Now install Oracle JDK 1.8, that recommended version for React Native Development. You can install using the following command
sudo apt install oracle-java8-installer
3.4 Set default Version
You can install multiple Java Installation in one machine version. For React Native mobile app development 1.8 is more stable. Consequently, we will need to set Java 1.8 as default, for do that run the below command
sudo apt install oracle-java8-set-default
3.5 Now verify java installation
4. Android development environment
Setting up your development environment is a little bit difficult, So I would like to suggest you go with easy step
4.1 Install AndroidStudio
Download and install Android Studio You can have to recommend installation type. If you are familiar with AndroidStudio, You can Choose a “Custom” setup when prompted to select an installation type. And ensure the boxes next to all of the following are checked:
- Android SDK
- Android SDK Platform
- AVD (Android Virtual Device)
But I personally recommend you have to choose recommend type during installation
4.2 Now, Configure the ANDROID_HOME environment variable
Now we have to set up some environment variables. Because React Native tools require some environment variables to be set up in order to build apps with native code.
4.3 Go to terminal and run command
Now on file will open in terminal copy the below line and save the file
export ANDROID_HOME=$HOME/Android/Sdk export PATH=$PATH:$ANDROID_HOME/emulator export PATH=$PATH:$ANDROID_HOME/tools export PATH=$PATH:$ANDROID_HOME/tools/bin export PATH=$PATH:$ANDROID_HOME/platform-tools
If you not able to edit this file you can run these command on terminal also
5. Creating a Sample application
For do that open terminal and goes into the folder where you want to create a new project and run the below command
react-native init SampleProject
6. Preparing AndroidDevice
You will need to Android device to run your ReactNative App. It can be either physical or virtual Android device .
6.1 Physical Device
For running app for physical device you will need to Enable Debugging over USB and Plug in your device via USB
6.2 Virtual Device (emulator)
To do that open the android studio and create a virtual device . and power up AVD.
6.3 Verifying device is connected or not run this command
After running this command list of connected devices will display on terminal
7. Run React Native App
Go to inside the project folder
8. Finally run the app the app using this command
Congratulations! You’ve successfully run your first React Native app.
