Modern web applications are developed with many popular frameworks like Angular JS, bootstrap and so on. These frameworks are based on popular Javascript frameworks. But when it comes to developing server-based applications, Node.js comes into the focus. It is also based on the JavaScript framework but used for developing server-based applications. In 2020, Node.js turned 11 years old, and the number of packages available on npm crossed one million. Downloads for Node.js itself continue to rise, growing 40% year over year. A lot has happened in a relatively short amount of time! Each year the Node.js community has gained momentum, and 2020 shows no signs of slowing down.
