The frontend is a Single-Page App implemented with Vue 3. Development uses the Vite server together with the main Python backend, but in production the latter also serves the prebuilt frontend files.
TypeScript cannot handle type information for `.vue` imports by default, so we replace the `tsc` CLI with `vue-tsc` for type checking. In editors, we need [TypeScript Vue Plugin (Volar)](https://marketplace.visualstudio.com/items?itemName=Vue.vscode-typescript-vue-plugin) to make the TypeScript language service aware of `.vue` types.
If the standalone TypeScript plugin doesn't feel fast enough to you, Volar has also implemented a [Take Over Mode](https://github.com/johnsoncodehk/volar/discussions/471#discussioncomment-1361669) that is more performant. You can enable it by the following steps:
1. Disable the built-in TypeScript Extension
1) Run `Extensions: Show Built-in Extensions` from VSCode's command palette
2) Find `TypeScript and JavaScript Language Features`, right click and select `Disable (Workspace)`
2. Reload the VSCode window by running `Developer: Reload Window` from the command palette.
