When I run:
npm install my-app
The app is installed into node_modules/my-app/...
I also tried
npm install -g my-app
You ought to have a package.json
in your current directory.
Then write npm install <module_name> --save-dev
or npm install <module_name> --save
and it will install to the node_modules directory
npm install
installs packages either locally or globally:
npm
looks for an existing folder called node_modules
in the current directory and creates a folder for each package you install in that folder. If it can't find an existing node_modules
folder here, it then looks through the current directory's ancestors until it finds one. If it can't find one, it creates one in the current directory.-g
(global) option, the package is installed in a global location. This location varies per Linux distribution, but /usr/local/lib/node_modules/packagename
is one example. CentOS7 uses /usr/lib/node_modules/packagename
.You should only use -g
when the package is something you'd want to use as a command.
Just like how global variables are kind of gross, but also necessary in some cases, global packages are important, but best avoided if not needed.
In general, the rule of thumb is:
- If you’re installing something that you want to use in your program, using
require('whatever')
, then install it locally, at the root of your project.- If you’re installing something that you want to use in your shell, on the command line or something, install it globally, so that its binaries end up in your
PATH
environment variable.
npm will not install a package's files directly into the current directory.
However, this is actually a good thing. It keeps dependencies' files separate from your app, and Node automatically searches the node_modules folder when you require something.
This is how you can install a module to your current directory:
npm i --prefix ./ my-app
As others have said, the proper way is to configure your project via package.json
pack=$(npm pack <package>) ; tar xzvf ${pack} --strip-components=1 ; rm ${pack} ; npm i
As @dalu said, if you want to have local packages, you'll need a package.json
file.
But to create the package.json
file, you will have to initialize npm by running npm init
.
You can then use npm install <module_name> --save[-dev]
.
I think the real question, what I and the OP would want, is to install my-app, like you would install an application , i.e. Install a top level application, that I am going to "use" as an application and not "require" as a module.
The fact that npm installs one level down from my application directory, is a purely aesthetic objection by new npm users.
When I started using npm (not so long ago), I solved it by having a git project as an installer, clone the git, run the install script, but now I am used to it and it does not bother me to have the app in the "wrong" folder any more.
Just setup some .sh, .bat or short cuts in the right place and your users, won't notice.
