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.

Recommended IDE Setup

VSCode + Volar (and disable Vetur) + TypeScript Vue Plugin (Volar).

Type Support for `.vue` Imports in TS

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) 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 that is more performant. You can enable it by the following steps:

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)
Reload the VSCode window by running Developer: Reload Window from the command palette.

Hot-Reload for Development

Run the backend

hatch shell
cista --dev -l :8000

And the Vite server (in another terminal)

cd frontend
npm install
npm run dev

Browse to Vite, which will proxy API requests to port 8000. Both servers live reload changes.

Type-Check, Compile and Minify for Production

This is also called by hatch build during Python packaging:

npm run build
