FAQs

1) How many Node.js libraries are there?

Multiple Node.js libraries are created to serve a purpose and have specific functionality. There are more than 83 Node.js libraries available that helps developers to create more robust web applications.

2) What is the difference between the Node.js library and the framework?

A library helps with the complexity and focuses more on the reuse of code, whereas a framework reduces complexities for developers. A framework has abstract away behaviour, logic and even architectural patterns that can be used in making a new project. One of the most important technical difference between library and framework are called the inversion of control. In a library you are in charge of the application flow. You can choose where and when you can call the library. But when using a framework, it is in charge of the workflow.

3) What are NPM libraries?

NPM libraries are the world’s; largest software registry and contain over 800,000 codes. All open-sourced developers use npm to share software details. Multiple organizations use npm to manage their private development. There are more than 1.3 million packages available in the main npm registry.

4) Is react a node library?

No. Both Node.js and React.js are different. Node.js is mainly used for the backend development with the JavaScript technology where as React.js is used for front end development.

React is a JavaScript library that is used to help in the creation of user interfaces. This was authored by Facebook and Instagram engineers. It was aimed to help solve the problems involved when developing a complex user interface with databases that keep changing over time.
