The npm init command in JSON language creates a package.json file for the frontend of your project. A package.json file is a file that contains information about the packages and dependencies of the project. It also contains metadata for the project such as version number, author and description.

Using the npm commands is done through the command line tool, and init is just one of many commands npm responds to. In this introduction, we’ll learn what npm is, what a package.json file is, and what the npm init command does. By the end of this guide, you will have a clearer idea of ‚Äã‚Äãhow to use the npm init command.

What is npm?

Created as a package manager and installer, JSON . Structuring the package file in this way makes it easier for developers to read and makes it easier for computers to analyze the information.

An example package.json file might look like this:

Here we can see that only the name and version number are included in the list of prompts. These are the only ones required, but in general providing more information is considered best practice. So let’s see the list of dependencies that this particular project needs to run.

The dependency structure is a nested JSON object with key / value pairs. The keys are the name of the dependency and the values ‚Äã‚Äãpoint to their respective version numbers. In this example, there are several test packages and packages for React.

Since this interface is built with React, the project should know that it depends on React to function and that with the React packages listed in the package.json file, they can also be installed from the line of command.

Conclusion

Using npm init from the command line initializes the project’s package.json file. This file contains information about the project itself , such as name and version number. The project’s dependencies are listed.

Dependencies are the packages that the project needs to function properly. The list in the file package. json allows you to install them before building the project. package.json file generated by calling npm init must be written in JSON format.

My Knowing that you have an introduction to using npm init and what a package.json file is, try starting your next project using npm init.

I was preparing for my coding interview, thanks for clarifying this - Use Npm In Javascript in Python is not the simplest one. I just hope that will not emerge anymore

Simply put and clear. Thank you for sharing. Use Npm In Javascript and other issues with struct Python module was always my weak point 😁. I just hope that will not emerge anymore
