Still in draft mode, running tests on Azure DevOps.

Fixes #2939

Changelog Entry

Description

• Bubbles are now grouped in transcript with 2-level grouping
  • Group by sender, then group by status
  • Status = timestamp or "Send failed." prompt
• Avatar grouping can be set at 3 different levels:
  • Avatar on activities sharing the same sender
  • Avatar on activities sharing the same status (default)
  • Avatar on every activity
• Added 2 hooks to deprecate older hooks with a newer API which is more consistent and flexible
  • useCreateActivityRenderer will replace useRenderActivity
  • useCreateActivityStatsuRenderer will replace useRenderActivityStatus
• Simplification of avatar options
  • Avatar will align top/bottom depends on nub position
  • Avatar gutter (space reserved for avatar) will be either fixed width, or zero (no avatar). Default width is 40px

New createRenderActivity hook

Tests are added to make sure: new hooks works with old middleware. The new middleware with old hooks.

The old signature is:

const renderActivity = useRenderActivity();
const element = renderActivity({ activity });

return <div>{element}</div>;

The new signature is:

const createActivityRenderer = useCreateActivityRenderer();
const renderActivity = createActivityRenderer({ activity }); // If renderer decided to skip this activity, it will return `false`
const element = renderActivity && renderActivity({ hideTimestamp: false }); // Render-time options

return <div>{element}</div>;

New createRenderActivityStatus hook

Tests are added to make sure: new hooks works with old middleware. The new middleware with old hooks.

The old signature is:

const element = useRenderActivityStatus({ activity });

return <div>{element}</div>;

The new signature is:

const createActivityStatusRenderer = useCreateActivityStatusRenderer();
const renderActivityStatus = createActivityStatusRenderer({ activity });
const element = renderActivityStatus && renderActivityStatus();

return <div>{element}</div>;

Specific Changes

Screenshot changes

There are 5 types of screenshot changes:

1. New tests
   • Layout tests: transcript.*.html, activityGrouping.*.html
   • Hooks tests: hooks.useCreate*.html, hooks.useRender*.html
2. (~80%) Font anti-aliasing issue.
3. Avatar gutter now have fixed width.
4. The newer set for carousel layout is now pixel-perfect with stacked layout.
   • The activity status in previous set was 1-2 pixels off vertically
5. Side must either has avatar, or don't have avatar at all.
   • We no longer support hybrid (some bubbles on one side has avatar, some don't)
   • It is okay to have avatar on one side, and no avatar on another side

Additional context

How it works

This show avatar on activities sharing the same status.

Font anti-alias

Updating many screenshots because of anti-alias. Cause is unknown but usually caused by bumping versions of Docker + Chrome.

Pixel-perfect carousel layout

Green layer is the old stacked layout (also same as the new carousel layout).

Red layer is the old carousel layout, which is a 1-2px offset from the old stacked layout.

We updated the carousel layout so it will align with the stacked layout for consistency. We chose stacked layout because it is the default layout.
