When working backend development you usually work with languages such as Node JS, Php, Python, Ruby, Java, etc. You have to set up the development environment for these languages. With the help of this article you setup a backend development environment on your Ubuntu 18.04 machine.

Node JS

Node.js is an open-source server-side framework built on Javascript. Node.js runs on service which is basically Javascript.

Let's install Node JS

sudo apt install nodejs

When the installation completes you can confirm the version of Node by:

node -v

node --version

NPM: To install packages you have to install node package manager NPM:

sudo apt install npm

YARN: To install yarn on Ubuntu 18.04 you need to configure the repo.

curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -

echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list

Now install yarn

sudo apt update && sudo apt install yarn

To confirm installation you can check the version of yarn

yarn --version

Python

Python is a server-side scripting language best known for Machine learning, Data learning, and Automation. Let's install Python 3 in this section. Run these commands in order to install Python 3 in your Ubuntu 18.04

sudo apt-get update

sudo apt-get install python3

To confirm the installation you can run

python3 -V

Since you are using python3, we will install Python 3 pip, Let's do that

sudo apt install -y python3-pip

To confirm the installation of Pip3, you can write

sudo python3-pip --version

Php

Php is a server-side language that is popular for its speed and popularity. Let's install PHP on Ubuntu 18.04,

sudo apt install php libapache2-mod-php

The above command will install the latest version of PHP compatible with apache.

To confirm the installation of Php you need to run:

php --version

This will return something like.

PHP 7.2.24-0ubuntu0.18.04.6 (cli) (built: May 26 2020 13:09:11) ( NTS )
    Copyright (c) 1997-2018 The PHP Group
