Feature Request: add builtin cache support

[trim21]

like https://github.com/actions/setup-node caching npm and yarn package

suggest a feature to cache installed package with install

[Kolobok12309]

@trim21 But setup-node has pnpm cache option

https://github.com/actions/setup-node/blob/main/docs/advanced-usage.md#caching-packages-data

[trim21]

oh thanks

I would suggest reopening this; we are using a self-hosted runner and are not using setup-node because node is preinstalled. As such... we can't use setup-node's cache option.

Having to add THREE steps to use pnpm with caching is kinda ugly.

I'm looking into making a PR for this. @trim21 would you mind reopening?
