Updating Packages
The easiest way is to use the npm-check-updates package. Yes, that is correct - NPM's update is so bad, you need to use a seperate package to make it work better…
npm install -g npm-check-updates | Installs npm-check-updates |
npm-check-updates | Lists what packages are out of date (basically the same thing as running npm outdated) |
npm-check-updates -u | Updates all the versions in your package.json file. |
npm update | To install the new versions of your packages based on the updated package.json file. |
For global packages:
npm-check-updates -g (Run as admin) | Lists what global packages are out of date and gives the command to update them. |
Versioning
^1.2.3 | Means any 1.x.y version that is equal or higher than 1.2.3 and less than 2.0.0. |
^0.1.2 | The leading zero is a special case. Means any 0.1.x version that is equal or higher than 0.1.2 and less than 0.2.0. |
~2.4.5 | Patch version only. Means any 2.4.x version that is equal or higher than 2.4.5 and less than 2.5.0. |
