How to update dependencies

Dependencies in the NodeJS world change constantly and packages get outdated quite fast. Usually you could keep things as they were originally developed, but this being a high-load, user-facing app, you need to take care of new found vulnerabilities. Use the following as a guide (not fullproof) to update the dependencies.

Start with installing the following package globally, in order to check for outdated versions. Then run it in the frontend folder and a full list of outdated dependencies will be shown, along with the latest. Attention: Never automatically update all deps at one time, unless they all have only patch changes.

# Install globally
npm i -g npm-check-updates

# List outdated
ncu

# Update a specific package
ncu -f NAME_OF_THE_PACKAGE -i

Then you can interactively choose a single package to update manually, in interactive mode. The guideline is to always check if the version change is major/minor/patch (shown by which part of the version number changed).

For minor or patch changes, it is generally easy to update automatically to the latest, but you might want to check the release notes on the package's GitHub page (which you can access directly from NPM). For major changes, always check if the peer dependencies changed, if the release notes deprecate an API or if they have an upgrade guide.
