Updating packages downloaded from the registry

Updating local and global packages you downloaded from the registry helps keep your code and tools stable, usable, and secure.

Updating local packages

[TK - decide if keeping video]

We recommend regularly updating the local packages your project depends on to improve your code as improvements to its dependencies are made.

  1. Navigate to the root directory of your project and ensure it contains a package.json file:
    cd /path/to/project
    
  2. In your project root directory, run the [update][npm-update] command:
    npm update
    
  3. To test the update, run the [outdated][npm-outdated] command. There should not be any output.
    npm outdated
    

Updating globally-installed packages

Note: If you are using npm version 2.6.0 or less, run [this script](https://gist.github.com/othiym23/4ac31155da23962afd0e) to update all outdated global packages. However, please consider upgrading to the latest version of npm: ``` npm install npm@latest -g ```

Determining which global packages need updating

To see which global packages need to be updated, on the command line, run:

npm outdated -g --depth=0

Updating a single global package

To update a single global package, on the command line, run:

npm update -g <package_name>

Updating all globally-installed packages

To update all global packages, on the command line, run:

npm update -g

npm-update npm-outdated
