Auto-updating Github Action matrix for node (i.e. ci-config-github-actions) #416
Description
I played around with this a little bit, and since the only re-usable primitive in Github Actions is a step packaged as an "action", the only possible implementation to have an auto-updating matrix is something like this:
jobs:
prepare-node-matrix:
runs-on: ubuntu-latest
outputs:
matrix: ${{ steps.set-matrix.outputs.matrix }}
steps:
- uses: nodejs/ci-config-github-actions@master
id: set-matrix
with:
gte: 10
policy: lts
test:
needs: prepare-node-matrix
strategy:
matrix:
node-version: ${{ fromJson(needs.prepare-node-matrix.outputs.matrix) }}1️⃣ Which is suuuuuuuper verbose? Did I miss something? What do people do to solve this issue - do they generate actions or smth from templates? Would we need a CLI or smth to help with that generation? I can't imagine someone copy/pasting that across hundreds of repos in an organization?
2️⃣ It also makes wonder if it's worth maintaining an action, when instead of the uses: nodejs/ci-config-github-actions@master block (5 lines) you could run: npx @pkgjs/node-matrix --gte 10 --policy lts instead?
3️⃣ But if we are to keep the action - should we rename the repo to something that follows the action convetion better, e.g. nodejs/version-matrix-action?

Looks like something like what you're looking for is on the GitHub roadmap for Q2/2021? github/roadmap#98

Yes, can't wait for workflow partials!
In the meantime sounds like we'll want to build an installable module, so we'll see where that takes us, I guess.

So, in general, looks like this will be somewhat addressed by GH work, and in the meantime we agreed that maybe some node package, which fails things when workflows are out of date might be useful. I'll be doing some related work on wiby side, and will open a new issue if/when I have something that's worth sharing.
Closing this for now.

fwiw, I’ve made an action ( https://github.com/ljharb/actions/tree/HEAD/node/matrix ) which is reusable, supports semver strings, and is also always up to date. I’ll be using it on all 200-300 of my repos, so hopefully it’ll be reliable :-)
