Raspbian Install Node.js

Raspbian is the official operating system for the Raspberry Pi, and Node.js is a popular open source JavaScript runtime. Installing Node.js on your Raspberry Pi enables you to run a variety of JavaScript applications and scripts. This article will walk you through the detailed steps to install Node.js on Raspbian.

Step One: Update Raspbian

Before you start installing Node.js, make sure the Raspbian operating system on your Raspberry Pi is updated. Connect to the Raspberry Pi via SSH or terminal and run the following command:

sudo apt-get update
sudo apt-get upgrade

This will update the operating system and its associated software.

Step 2: Download and install Node.js

Now, we can download and install Node.js. Open a terminal or SSH on your Raspberry Pi and run the following command to download the latest version of Node.js from the official Node.js website:

wget https://nodejs.org/dist/latest/node-vxx.xx.x-linux-armv7l.tar.gz

Please note that you need to replace "xx.xx.x" with the latest version The Node.js version number. For example, if the latest version is 12.18.0, replace "xx.xx.x" with "12.18.0" in the above command.

Next, unzip the downloaded tarball file. Enter the following command:

tar -xzf node-vxx.xx.x-linux-armv7l.tar.gz

Now, we need to move the unzipped folder to the /usr/local directory. Use the following command:

sudo mv node-vxx.xx.x-linux-armv7l /usr/local/

Finally, add the Node.js binary to PATH. Enter the following command:

export PATH=$PATH:/usr/local/node-vxx.xx.x-linux-armv7l/bin

Note that again you need to replace "xx.xx.x" with the latest Node.js version number.

Node.js has been successfully installed at this time, but we may need to make some other configurations.

Step Three: Test Node.js

To test whether Node.js is working properly on the Raspberry Pi, try running the following command:

node -v

This should return the installation The version number of Node.js. If everything is OK, the number of the installed version will be output.

Step 4: Update npm

npm is the default package manager for Node.js. If you want to use npm, you'll also need to update it. To do this, run the following command:

sudo npm install npm@latest -g

This will update npm and install it in a global location.

Step Five: Completion

Now that you have successfully installed and configured Node.js, you can start running JavaScript applications and scripts on your Raspberry Pi.

Summary

In this article, you learned how to install Node.js in Raspbian. You need to update your operating system, then download Node.js from the official Node.js website and extract it into the /usr/local directory. Then, add the path to Node.js to PATH. Finally, you need to test whether Node.js works properly on the Raspberry Pi and how to update the npm version.

Node.js provides many useful functions and libraries that provide useful extension capabilities to the Raspberry Pi. Using Node.js on Raspberry Pi, you can easily implement various IoT projects and other innovative devices.
