logan 218e4f5e99 feat(player): give the transport a context, and thumb-sized controls
Measured at the reference device's 424x439, every button here was
33x21px -- in the bottom bar and on the full-screen view alike. #56
reports them as "the most important thing in the mobile app and they
are tiny", and that is the number behind it.

The context is a **property, not a media query**, and that is the whole
design. Everywhere else in this app a component states what it drops at
phone width itself, because a media query inside a shadow root is
answered by the viewport and that is the honest signal. Here the two
hosts want different answers at the *same* viewport: on a phone the bar
wants three controls sized for a thumb and now-playing-view wants five,
larger still. So the host says which context and the viewport says
which size band, and neither alone can express it.

Play/pause alone goes above the 44px floor. A row of five identical
squares says every action is equally likely, which is not true of play
-- "large play/pause, adequate prev/next" is the Direction, and a spec
caught that the first version had sized all three the same.

Two things that fail silently:

The desktop bar must not move, and a `<button>` does not inherit its
font from its parent -- the UA stylesheet gives it one. So a generic
`font-size: inherit` is not the no-op it reads as: it took every
desktop control from 33x21 to 36x24. The box rules take a zero fallback
and the font-size rules are scoped to the two contexts that set one.

And the art on now-playing-view overflowed its own box, drawing over
the header above and the title below, because `aspect-ratio: 1` with a
definite width derives a height that nothing bounds -- 60vh bounds the
viewport, not the room left over. `max-height: 100%`. Pre-existing;
found by reading a screenshot, which is the only tier that can see it.

What is left is #172: with the transport at 172px of a 439px screen the
art is a 39px sliver.

Closes #56

YellowJacket Frontend

This directory contains the frontend for YellowJacket.

Dependencies

There are a couple of tools that are required to build and use the frontend.

  • vite for
    • transpiling typescript
    • bundling the final "package" that is useb by the webview
    • running a dev server with hot-reloading
    • configured with the vite.config.ts file in this directory
  • pnpm for managing frontend dependency packages

There are a handful of dependency packages that we use directly in the frontend.

Lastly, there are some dependencies that only benefit development

  • tsserver comes bundled with vscode and can be used as an LSP with other editors using typescript-language-server
    • Used for autocomplete, syntax highlighting, etc.
    • This can be configured with the tsconfig.json file in the root of the project
      • NOTE: your configuration should align with the vite config so you get in-editor feedback that aligns with how the build will be done.

Development

Ideally, you would use the frontend in the wails app as the frontend depends on the Go bindings generated by Wails. You can do this by running wails dev in the root of the YellowJacket repo.

If you want to run the frontend standalone, make sure the Wails go bindings have been generated with wails generate modules. Then, you can run pnpm dev to run the vite dev server. For more information on what commands are available, refer to package.json.

Code

Web Components

Our frontend is based off of Web Components, a standard that provides native browser encapsulation of components that can include HTML, CSS and Javascript all together. Instead of writing these components manually in Javascript, we utilize lit as a wrapper library.

Typescript

To better integrate with our tooling and to provide a better developer experience with strong typing, we have written all functional frontend code in Typescript. Vite serves as our Typescript transpiler.

Important Files and Directories

NOTE: most of these directories have aliases defined in tsconfig.json and vite.config.ts so that we may refer to them by shorthand when importing.

  • index.html and index.js is the entrypoint for the frontend. The first page that loads.
  • wailsjs/go Go code bindings generated by wails reside here
  • wailsjs/runtime the Wails runtime code needed to use Wails features
  • src all app code resides here
  • src/assets static assets like fonts, images and icons
  • src/components lit components that are used to compose the application
  • src/pages pages that serve as other entrypoints for the application that can be navigated to
