How to upgrade nodejs in linux

Node.js is a popular JavaScript runtime environment that can run on different operating systems, including Linux systems. Due to the rapid development and maintenance of Node.js, please make sure to try the latest version frequently. In this article, we will introduce how to upgrade Node.js to the latest version.

1. Check the current version

Before upgrading Node.js, you need to know the currently installed version. You can check the current version by entering the following command in the Terminal:

node -v

If Node.js is not currently installed, you need to install it. You can install it through the following command:

sudo apt-get install nodejs

2. Select the version of Node.js to install

You can find the latest Node.js version through the official Node.js website. I recommend installing LTS (Long Term Support) versions as they are stable, reliable and have long-term support.

In this tutorial, we will upgrade to the latest LTS version, which is 12.x. To do this, we need to download the Node.js binaries and install them manually.

3. Download the latest version of the binary file

In the terminal, enter the following command to download the latest version of the Node.js binary file:

wget https://nodejs.org/dist/latest-v12.x/node-v12.x.x-linux-x64.tar.gz

Please Note replacing "x" with the version number. The latest version number can be found on the official Node.js website.

4. Unzip the binary file

In the terminal, enter the following command to unzip the downloaded binary file:

tar -xf node-v12.x.x-linux-x64.tar.gz

5. Install Node.js

In order to install the new Node.js version, we need to move the unzipped file to the /usr/local directory and rename it to node. In the terminal, enter the following command:

sudo mv node-v12.x.x-linux-x64 /usr/local/
sudo mv /usr/local/node-v12.x.x-linux-x64 /usr/local/node

Once completed, enter the following command to confirm that Node.js is installed correctly:

node -v

6. Update npm

npm is the package manager for Node.js. In order to ensure that it can still work properly after installing the latest version of Node.js, you need to update the npm version. In the terminal, enter the following command:

npm install -g npm

Once completed, enter the following command to confirm that npm has been installed correctly:

npm -v

7. Conclusion
