frontend/wailsjs/ is deleted and frontend/bindings/ takes its place — a real TypeScript module tree nested by Go import path, generated by wails3's static analyser rather than by building the app and running it. The @go alias absorbs the constant prefix, so a call site imports '@go/library/library.js' and the codemod over all 93 sites was a specifier rewrite plus splitting @go/models' namespaces into one import per package. The 12 SetContext bindings and the fake `context` model are gone, as Phase 2's ServiceStartup port promised: 272 methods across 12 services, none of them plumbing. @runtime/runtime is now a local shim (src/wails/runtime.ts) over @wailsio/runtime, so the 22 EventsOn imports are untouched. It unwraps v3's WailsEvent into v2's callback shape, which is exact here: nothing in backend/events passes more than one data argument, and v3 only packs arguments into a slice when there is more than one. v3 tells the truth about two things v2 lied about, and that is most of the diff. A Go nil slice really does arrive as JSON null, and a Go named string type really is an enum; v2 typed them as T[] and string. utils/binding.ts states the app's actual contract — an absent list is an empty list — once, at the boundary where it is true, and also drops the CancellablePromise the app never cancels. Four test fixtures widen an enum field back to its value union. Not done, and Phase 5's to fix: frontend/test/support/wails-fake.ts still fakes window.go, which v3 does not have, so `make ui-test` is broken and harness.test.ts fails to compile on EventsEmit. That test also asserts v2 ordering that no longer holds — v3's Events.Emit calls the backend and does not notify in-page listeners at all.

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.
