`index.ts` caches primary views and hides them with a class so scrollTop survives navigation. Nothing else was told: `disconnectedCallback` never fires for one, so everything written to clean up there never cleans up. The worst case was not a leak — pressing `s` on Settings skipped two albums out of the Autotag queue, and `a` on that same live handler rewrites tags on disk. - `utils/view-lifecycle.ts` is the missing half: `viewActivated` / `viewDeactivated`, with `listenWhileActive`, `intervalWhileActive` and `whileActive` torn down on the way out, and an off-screen view that does not render. `registerViewAware` gives a shared reactive controller the same treatment, because a controller cannot know whether its host is a cached view — `ContextMenuController` bound three document listeners in `hostConnected`, which for a cached host is "forever". - `services/shortcut-scope.ts` publishes the ambient scope. Resolving scope from focus alone was not enough: this app is driven with the mouse, focus sits on `<body>`, and a focus-only rule would have made the panel keys work only after a click landed inside the panel. - Global bindings yield to a focused control that owns the key — button, select, slider, checkbox, menu, grid row, or anything inside an open dialog — so the unmodified single-key bindings stop stealing Space and the arrows. - `utils/roving-grid.ts` gives a card grid one tab stop moved with the arrows, since a card per tab stop makes a library-length tab sequence.
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.
vitefor- transpiling typescript
- bundling the final "package" that is useb by the webview
- running a dev server with hot-reloading
- configured with the
vite.config.tsfile in this directory
pnpmfor managing frontend dependency packages
There are a handful of dependency packages that we use directly in the frontend.
picocssfor basic CSS while developinglitfor a simple but powerful wrapper around Web Components
Lastly, there are some dependencies that only benefit development
tsservercomes bundled with vscode and can be used as an LSP with other editors usingtypescript-language-server- Used for autocomplete, syntax highlighting, etc.
- This can be configured with the
tsconfig.jsonfile in the root of the project- NOTE: your configuration should align with the
viteconfig 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.
