Steps for installing a package using npm without the need for configuring a package.json file

According to this source, it is feasible to install npm packages before creating the package.json file.

After installing nodeJS on my computer, I attempted to run the following command in an empty directory:

npm install jQuery

This resulted in the following error message in the console:

D:\Rasik\reactJs\learnJs
`-- [email protected]
npm WARN enoent ENOENT: no such file or directory, open 'D:\Rasik\reactJs\learnJs\package.json'
npm WARN learnJs No description
npm WARN learnJs No repository field.
npm WARN learnJs No README data
npm WARN learnJs No license field.

I am currently working on an HTML Vanilla JavaScript (JS) project and aiming to utilize npm to obtain the latest packages or JS files. However, I prefer not to execute npm init prior to installing the packages as this project does not fall under the category of a ReactJS application.

Answer №1

Instead of uploading the entire node modules folder to Github, it is recommended to install npm packages with a package.json file. You can easily set up a package.json by running npm init and following the prompts or use npm init -y for default values.

A package.json file makes it easier to share your code as you only need to run npm install to download all dependencies. Without a package.json file, sharing code becomes more difficult as you would have to manually copy all folders in node_modules.

Answer №2

My oversight led to a mistake as I failed to notice the node_modules directory. Installing or uninstalling packages through NPM does not require any extra effort or prerequisites. You can install any node package even without a package.json file in your root directory (which is generated by using the npm init command).

When you run npm install jQuery, it installs the jQuery module and creates a \node_modules\jquery directory in the root folder with all necessary files.

Furthermore, the package name used in the npm install command is case insensitive, so these commands are all equivalent:

npm install jquery
npm install jQuery
npm install jQuErY

Answer №3

Did you attempt to execute the command npm config get save to verify if the --save parameter is configured as true or false?
