Read the npm guide if you are starting out with npm, itโs going to go in a lot of the basic details of it.
When you install a package using npm
(or yarn), you can perform 2 types of installation:
By default, when you type an npm install
command, like:
npm install lodash
the package is installed in the current file tree, under the node_modules
subfolder.
As this happens, npm
also adds the lodash
entry in the dependencies
property of the package.json
file present in the current folder.
A global installation is performed using the -g
flag:
npm install -g lodash
When this happens, npm wonโt install the package under the local folder, but instead, it will use a global location.
Where, exactly?
The npm root -g
command will tell you where that exact location is on your machine.
On macOS or Linux this location could be /usr/local/lib/node_modules
.
On Windows it could be C:\Users\YOU\AppData\Roaming\npm\node_modules
If you use nvm
to manage Node.js versions, however, that location would differ.
I for example use nvm
and my packages location was shown as /Users/flavio/.nvm/versions/node/v8.9.0/lib/node_modules
.
