what is the purpose of "npm install package-name --no-save"?

I mean why would anyone install a package temporarily and not add it to the dependencies list ?

--no-save uses?

Solution

  • Maybe you just want to test an idea without the need to add a package in the dependency or devDependencies of your package.json file.

    if you run:

    npm install --no-save express

    now, if you check your node_modules folder the package is downloaded but package.json is not updated.

    When you try to run your code, since express is available in node_module it can be picked up by your code or any third party library that you have in your project.
