TIL that it's possible to manage via nvm. not only node versions, but also
yarn versions.
The advantage of doing so (instead of one single installation via brew, for
example), is that you're able to pin a specific yarn version to each node
version.
For already installed node versions, make sure you're using the intended
version (i.e., which node should print something like
$NVM_DIR/versions/node/v20.10.0/bin/node) and then run npm install -g yarn.
For future node versions you'll install, there's a way to automatically
install yarn alongside node, without needing to explicitly install.
We can use nvm's default global packages from file while
installing.
To do so, create a text file at $NVM_DIR/default-packages:
yarn
Now no more old versions of yarn 🎉, you'll get the latest every time you
install a new node version.
You can also explore the possibility of adding other npm packages that might
interest you, such as @vue/cli or nuxi, for example.
