Something I learned the other day is that

@actions/setup-node

will preserve the per-user

npm

cache for you if you set

with:cache: npm

, and similar for

yarn

. This has been enough to get my Actions->Netlify pipeline[1] down to around ~90s. [1]: https://luke.carrier.im/notes/soAskHwFxI1EM8dZIDvBN/
