• Check outdated packages

npm outdated

• Update local packages according to package.json

npm update

• Upgrade packages manually

npm install --save[-dev] <package_name>@latest

Alternatively, you can use npm-check to perform an interactive upgrade:

npm-check -u --skip-unused

Locking package versions

Starting from npm@5 a new package-lock.json file is automatically generated when using npm install commands, to ensure a reproducible dependency tree and avoid unwanted package updates.

If you use a previous npm version, it is recommended to use npm shrinkwrap to lock down all your dependencies version:

npm shrinkwrap --dev

This will create a file npm-shrinkwrap.json alongside your package.json files.

Do not forget to run shrinkwrap each time you manually update your dependencies!
