NodeJs Setup on Raspberry Pi
Prerequisites
Before you begin, you will need the following:
- A Raspberry Pi with Raspbian installed
- Access to the terminal on your Raspberry Pi
Installation
Step 1: Update the Package List
The first step is to update the package list on your Raspberry Pi. This will ensure that you have the latest information about available packages.
Run the following command to update the package list:
sudo apt update
Step 2: Install Node.js
Next, you will need to install Node.js on your Raspberry Pi. You can do this by running the following command:
sudo apt install nodejs
Step 3: Install npm
After installing Node.js, you will also need to install npm, which is the Node.js package manager. You can do this by running the following command:
sudo apt install npm
Step 4: Verify the Installation
To verify that Node.js and npm have been installed correctly, you can check the versions of both tools by running the following commands:
node -v
npm -v
If the installation was successful, you should see the version numbers of Node.js and npm displayed in the terminal.
Step 5: Create a Test File
To test that Node.js is working correctly on your Raspberry Pi, you can create a simple test file. Create a new file called test.js by running the following command:
nano test.js
In the text editor, add the following code:
console.log('Hello, World!');
Save and exit the text editor by pressing Ctrl + X, then Y, and finally Enter.
Step 6: Run the Test File
To run the test file, use the following command:
node test.js
If Node.js is working correctly, you should see Hello, World! displayed in the terminal.
Congratulations! You have successfully installed Node.js on your Raspberry Pi. You can now start developing applications using Node.js on your device.
If you have any questions or run into any issues, feel free to refer to the Node.js documentation for more information.
Conclusion
You have successfully installed Node.js and npm on your Raspberry Pi. You can now use these tools to develop and run Node.js applications on your device. If you have any questions or run into any issues, feel free to refer to the Node.js documentation for more information.
