- Check outdated packages
npm outdated- Update local packages according to
package.json
npm update- Upgrade packages manually
npm install --save[-dev] <package_name>@latestAlternatively, you can use npm-check to perform an interactive upgrade:
npm-check -u --skip-unusedStarting 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 --devThis 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!
See the Angular update website to guide you through the updating/upgrading steps.
