How do these work, how can I see what is hidden in this action, what does cache do here exactly?

meilisearch-js/.github/workflows/tests.yml

Lines 69 to 73 in 6cd64e9

	- name: Setup node
	uses: actions/setup-node@v4
	with:
	node-version: 20
	cache: 'yarn'

I need to know this, it might need adjustments.

EDIT: I'm guessing it sets up yarn if it's not already cached, and maybe something else. This requires changes. All it has to do is corepack enable instead of installing yarn.

EDIT: I thought this might require changes in instant-meilisearch as well as that uses actions/setup-node@v4 too, but by default corepack will install the latest version of Yarn 1.x as soon as you type yarn in the command line and there isn't any packageManager specified in the package.json of that repository.

Hi @flevi29, although I see the pnpm is faster than yarn, I don't think we should move away from the current package manager because we have yarn set up in the other js apps/libs across the org. Changing that to a different one will be a pain 😅.

Okay, fair enough. However my suggestion would make it so that nothing would have to be changed in all the other repositories.

Corepack lets you use Yarn, npm, and pnpm without having to install them. (https://github.com/nodejs/corepack)

We could adopt corepack, and manage package manager versions via the "packageManager" entry instead of globally.

• This would enable us to use whatever package manager we want in whatever JS repository, and for instance, adopt a new one like pnpm gradually, painlessly, if we so desire
• It's co-authored by Yarn, they even recommend it, and it's even the way they tell you to install the latest Yarn versions; read here more: https://yarnpkg.com/corepack and https://yarnpkg.com/getting-started/install
• If you don't want pnpm that's completely fine, but then let's upgrade yarn, we're still using 1.x, which is only a maintenance version, and to upgrade yarn we should absolutely adopt corepack

Closing as not planned.
