[sharedUX] Move to Package-based Architecture #127546

clintandrewhall · 2022-03-11T21:23:17Z

Summary

This was a subset of the work in #127419 for ease of review and commit history. The other three PRs were individually reviewed and then merged into this services PR.

This PR moves portions of the SharedUX plugin out of the plugin and into packages.

Why?

With only a few components, we've run into issues with circular dependencies. The reason being our plugin is consuming code and types from other plugins, and once we do, that plugin can't use our plugin or its components. To mitigate this, we need to keep Shared UX as dependency free as possible.

One of the approaches @majagrubic explored was moving pure components to another plugin to be consumed by dependency plugins. While it worked, we all agreed it wasn't ideal.

Talking with ops, it became clear our assets don't actually need a plugin lifecycle to operate. So I took some time this evening to decouple our components, services and utilities to packages.

Packages

@kbn/sharedux-services - Our base service abstraction definitions and mocks.
@kbn/sharedux-storybook - All storybook-related code, including a SB-impl of our service layer.
@kbn/sharedux-utility - A home for utility code.
@kbn/sharedux-components - React components
- As @spalger has pointed out, this package likely needs to be split apart into smaller packages. At present, we don't have a good sense of how components might be divided, so I'm opting to K.I.S.S. in the immediate term.

Code from src/plugins/shared_ux was refactored and moved to these packages.

Plugin

Now that most of the stateless code has been moved out of the Shared UX plugin, what is its purpose?

The Shared UX plugin provides stateful, Kibana-specific implementations of the services in @kbn/sharedux-services and a React context provider that wires components from @kbn/sharedux-components. Any plugin that is not a dependency for our services can make src/plugins/shared_ux a dependency and consume a pre-wired context that will make components from @kbn/sharedux-components "just work". To make life even easier, the Shared UX plugin re-exports these components, so this becomes an implementation detail.

The nice thing is, dependency plugins that still need to use components from Shared UX but need to avoid the circular dependency can either work with us to hoist the dependency, or consume the pure component from @kbn/sharedux-components, (as we attempted with #126491). I have no doubt there is a better work-around in the medium term, but we need to start somewhere.

I'll flesh out the rest of the details shortly, but I wanted to get this architecture out for feedback before we create more components. I know there's a pressing need to get NoDataView decoupled, so this PR becomes pressing, as well.

How to use services and components after this change

When a consumer of our components and services wants to use them, they have two choices:

use the pre-wired Context from the Shared UX plugin, or
wire it up themselves with their own services value.

Pre-wired Context

The Shared UX plugin imports the SharedUxServicesProvider and populates the services using a servicesFactory that uses Kibana dependencies to fulfill the contract. This is how consumers of the hooks get to the Kibana version of these services: the SharedUxServicesProvider provides the API to those hooks, (and thus the components).

Wiring Manually

You can consider the code in the Shared UX plugin to be a manual wiring of the Provider for components, but Storybook and Jest are also examples:

src/plugins/shared_ux/public/components/empty_state/no_data_views/no_data_views.stories.tsx

src/plugins/shared_ux/public/components/empty_state/no_data_views/no_data_views.test.tsx

src/plugins/shared_ux/public/components/empty_state/no_data_views/no_data_views.stories.tsx

src/plugins/shared_ux/public/components/index.ts

packages/kbn-shared-ux-services/src/context.tsx

I didn't mean to "request changes", just wrote some comments 😬 But since it's already there, it can read as "no merging until Maja understands how are the services wired" 😅

I accidentally left a comment in the PoC PR, so I'll just leave it here 😅

This should really be prioritized imho.

The architectural change looks good. I would just suggest moving that comment to my question to the PR description itself, for easier reference later on.
