chore: move non-shared code from frontend-shared to app #24674

lmiller1990 · 2022-11-14T14:33:17Z

While working on the Spec List code for #24467 with @amehta265, we found it confusing that a lot of functionality was split across frontend-shared and app. Turns out a lot of what was in frontend-shared isn't shared - it's exclusively consumed in app. For this reason, I decided to move the app only code into app. This makes it much easier to follow the code around.

There are no functionality changes here, I just deleted some unused code and moved some from around.

-}
-
-export function buildSpecTree<T extends FoundSpec> (specs: FoundSpec[], root: SpecTreeNode<T> = { name: '', isLeaf: false, children: [], id: '', highlightIndexes: [] }): SpecTreeNode<T> {


spec-utils ended up a dumping ground for random things - many of these functions have one very specific purpose, which is to build the spec tree (not just utils) so I moved them to a more accurately named file.

Moved from frontend-shared, no changes. This is not a shared file, it is only used in App.

Unused? I think a hold-over from before we used GraphQL and preferences to save the spec filter.

Yeah we don't seem to be reading it anywhere 👍

Unused, this was not doing anything but saving the specFilter in the store for no reason.

packages/app/src/specs/SpecsList.vue

 import RowDirectory from './RowDirectory.vue'
 import SpecItem from './SpecItem.vue'
-import { useVirtualList } from '@packages/frontend-shared/src/composables/useVirtualList'
+import { useVirtualList } from './tree/useVirtualList'


Since this has been backported to VueUse, do we want to try using the VueUse implementation: https://vueuse.org/core/usevirtuallist/#usevirtuallist

I wonder if we have diverged or if this will just work.

Nice, we should do this. Not right here, though -- I don't want to introduce any risk or change to code in this PR where possible - this is a quick reshuffling of things.

marktnoonan · 2022-11-14T20:33:06Z

Nice to clean some of this up! I have no problems with this move, though I had been thinking in an almost opposite way - that possibly more things should begin their life in frontend-shared since extracting things from one of the other packages was relatively painful and time consuming recently around auth/cloud stuff. Had to touch a lot tests and components just to use something we had already built and get it stable again everywhere.

This wouldn't happen if we saw the app and launchpad packages as sort of thin wrappers, and had frontend-shared as the core frontend source of components for both. Then we would always be able to reuse design elements in different contexts.

Not blocking though, just something I meant to bring up.

Is this ready for review? It's still in draft.

... that possibly more things should begin their life in frontend-shared since extracting things from one of the other packages was relatively painful ...

Why was it painful? I wasn't involved in this, but it should be as simple as moving and updating some imports. If it's not, our code is coupled to our build infrastructure - which means we should fix that. In this PR, I just did a bunch of dragging around VS Code and a few find and replaces.

This wouldn't happen if we saw the app and launchpad packages as sort of thin wrappers, and had frontend-shared as the core frontend source of components for both. Then we would always be able to reuse design elements in different contexts.

I do kind of agree with this. I think generic components are fine to include in frontend-shared. The main thing I'm moving here is useVirtualList, which may even go away once we update to the latest VueUse.

That said, the opposite end of argument would be "don't over abstract; refactor and make generic if you need it.

I don't feel too strongly about this either way, the main reason I made this PR is I think it'll make reviewing the upcoming Run All Specs changes a little easier, since we are probably touching that area quite a bit.

Is this ready for review? It's still in draft.

Moved to review!

Just adding my .02. I'm all for YAGNI, and keeping things as minimal as possible. However, I would suggest that we commit to starting the life of a component in frontend-shared. In addition to Mark's viewpoints, it also makes it much easier for a developer to discover an implementation if something already exists. We should be careful to not over generalize a component just because it lives here, though. Let the re-usablity be implemented as needed.

marktnoonan · 2022-11-15T18:43:07Z

Happy to approve, especially as a broken-out part of other work that makes reviews easier 👏

Moving the components was OK, the challenges were mostly around graphql data that the components we moved needed to access. Moving/renaming components meant updating a lot of GQL intercepts, for example, since the naming convent for fragments is tied to the component structure, and a few other things. We can chat more about it some time. Probably ties more into our test infra than the actual location of our files.

@rockindahizzy I'd be fine with "new components are created in frontend-shared by default" and not moving the old stuff right away. We can update the frontend-shared README to guide people to do this, and discuss whether the team agrees in that PR.
