"npm install [package]" doesn't update package.json

Question

I've been using Laravel and trying to use angular-ui-sortable and angular-utils-pagination.

I installed them with npm, but can't get package.json updated for angular-utils-pagination.

The file now looks like...

 {
  "private": true,
  "devDependencies": {
   "gulp": "^3.8.8"
  },
  "dependencies": {
    "angular-ui-sortable": "^0.14.0",
    "bootstrap-sass": "^3.0.0",
    "laravel-elixir": "^4.0.0"
  }
}

The point is that angular-ui-sortable is there but angular-utils-pagination is not. Both files are under node_module folder. As far as I understand, those libraries have to be under dependencies in package.json for them to be available.

Any advice will be appreciated.

Answer 1

To add a angular-utils-pagination under dependencies try:

npm install angular-utils-pagination --save

It should now appear in the package.json file.

For reference, adding dependencies to package.json:

npm install <package> --save

Adding dev dependencies to package.json:

npm install <package> --save-dev

Good luck!

Answer 2

In order to save the package in the package.json file as a dependency you need to write

npm install <package-name> --save 

if you want to save the package as a development package only (not to be installed on production server) write the following:

npm install <package-name> --save-dev

To install dependencies from the package.json file:

npm install *installs all dependencies*
npm install --production *will only install "dependencies"*
npm install --dev *will only install "devDependencies"*
