Motivation ========== Actions and commands -------------------- In the context of Data Views, there has been a lot of recent work towards providing a set of actions operating on posts, templates, patterns (e.g. rename post, edit post, duplicate template), and ultimately other entities. These actions, however, aren't unique to Data Views, and indeed exist in several different contexts (e.g. Site Editor inner sidebar, new Admin "shell" sidebar, Pages index view, Post Editor), so the next step was to unify actions across packages (e.g. #60486, #60754). The first unification effort led to an abstraction around a hook, `usePostActions`, but the consensus now is to remove it and expose the actions directly (#61040). Meanwhile, it has been noted that there is a strong parallel between these _actions_ and the Command Palette's _commands_, which has its own API already. This isn't a 1:1 mapping, but we should determine what the overlap is. Actions and side effects ------------------------ There is a limit to how much we can unify, because the context in which actions are triggered will determine what secondary effects are desired. For example, trashing a post inside the post editor should result in the client navigating elsewhere (e.g. edit.php), but there should be no such effect when trashing from a Data View index. The current solution for this is to let consumers of the `PostActions` component pass a callback as `onActionPerformed`. It works but there's a risk that it's too flexible, so I kept wondering about what kind of generalisations we could make here before we opened this up as an API. Extensibility ------------- As tracked in #61084, our system -- what ever it turns to be -- needs to become extensible soon. Somewhere in our GitHub conversations there was a suggestion to set up an imperative API like `registerAction` that third parties could leverage. I think that's fair, though we'll need to determine what kind of registry we want (scope and plurality). An imperative API that can be called in an initialisation step rather than as a call inside the render tree (e.g. `<Provider value=...>` or `useRegisterAction(...)`) is more convenient for developers, but introduces indirection. In this scenario, how do we implement those aforementioned _contextual side effects_ (e.g. navigate to page)? The experiment ============== It was in this context that I had the terrible thought of leveraging wp.hooks to provide a private API (to dogfood in Gutenberg core packages). But, of course, hooks are keyed by strings, and so they are necessarily public -- i.e., a third party can call `applyFilters('privateFilter'`, even if `privateFilter` is not meant to be used outside of core. This branch changes that assumption: hook names *must* be strings, *except* if they match a small set of hard-coded symbols. These symbols are only accessible via the lock/unlock API powered by the `private-apis` package. Thus, core packages can communicate amongst each other via hooks that no third party can use. For example: - An action triggers `doAction` with a symbol corresponding to its name (e.g. `postActions.renamePost`). - A consumer of actions, like the Page index view (PagePages), triggers a more contextual action (e.g. `pagePages.renamePost`). - A different component hooks to one of these actions, according to the intended specificity, to trigger a side effect like navigation. See for yourself: upon `pagePages.editPost`, the necessary navigation to said post is triggered by a subscriber of that action. Assessment ========== Having tried it, I think this is a poor idea. "Private hooks" as a concept is a cool way to see how far `private-apis` can take us, but they seem like the wrong tool for the current problem. Still, I wanted to share the work, hence this verbose commit. I think our next steps should be: - Finish the actions refactor (#61040) - Impose constraints on ourselves to try to achieve our feature goals with less powerful constructs than `onActionPerformed`. I'm still convinced we haven't done enough work to generalise side effects. Consider it along with the commands API. - Try a more classic registry-based approach for actions (`registerAction`)

I've started thinking about this a little bit (focusing on actions first). So we want to be able to define actions per post type and the first question I had to answer is where should the API live? In which package?
I'm thinking of starting exploring the "editor" package first and we can adapt over time. WDYT. |

I updated the issue with some tasks that can be grabbed. Let's keep it up to date as we iterate and clarify what needs to be done. |

Hello folks, Small update here.
I'm going to pause or slow down the work on the issue to focus on other priorities I have at the moment. But if folks are interested to continue push this forward, the todo list should help and I'm happy to provide support. cc @Mamaduka @jsnajdr @fabiankaegy |

Not sure if this is the right place to mention it, but I found this old issue, which seems relevant for data views for post types - Post actions: "force delete" isn't supported Testing today and the post editor shows ‘Move to trash’ as an action, but the post isn’t deleted when clicking it. |

What problem does this address?
As we grow the usage of the DataViews package in the different editors. The need for extensibility for the different configuration objects grows. The dataviews package is built in a way that allows extensibility to be implemented in multiple places and open a new wave of possibility for plugins and third-party developers:
We should be able to:
What others would you like to see being extensible in the dataviews? Let's gather some thoughts.
Note
A lot of the above features are still very much in flux and the structure of these objects will probably change (breaking changes) while we iterate there. In the meantime, it is important to get third-party feedback to shape these objects and extensibility APIs properly. And given the scale of these APIs, we should start implementing these APIs as Gutenberg plugin-only APIs, gather real usage feedback on the plugin before committing to shipping these APIs into Core.

IS_GUTENBERG_PLUGINas a start).Todo
