Teardowns were synchronous all the way through: POST blocked on the
worker's docker-compose-down cycle (seconds to minutes), the frontend
locked tearingDown to a single string so only one button could be armed
at a time, and operators couldn't queue a second teardown until the
first returned. On a flaky worker that meant staring at a spinner for
the whole RTT.
Backend: POST /swarm/hosts/{uuid}/teardown returns 202 the instant the
request is validated. Affected shards flip to state='tearing_down'
synchronously before the response so the UI reflects progress
immediately, then the actual AgentClient call + DB cleanup run in an
asyncio.create_task (tracked in a module-level set to survive GC and
to be drainable by tests). On failure the shard flips to
'teardown_failed' with the error recorded — nothing is re-raised,
since there's no caller to catch it.
Frontend: swap tearingDown / decommissioning from 'string | null' to
'Set<string>'. Each button tracks its own in-flight state; the poll
loop picks up the final shard state from the backend. Multiple
teardowns can now be queued without blocking each other.
React + TypeScript + Vite
This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
Currently, two official plugins are available:
- @vitejs/plugin-react uses Oxc
- @vitejs/plugin-react-swc uses SWC
React Compiler
The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see this documentation.
Expanding the ESLint configuration
If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:
export default defineConfig([
globalIgnores(['dist']),
{
files: ['**/*.{ts,tsx}'],
extends: [
// Other configs...
// Remove tseslint.configs.recommended and replace with this
tseslint.configs.recommendedTypeChecked,
// Alternatively, use this for stricter rules
tseslint.configs.strictTypeChecked,
// Optionally, add this for stylistic rules
tseslint.configs.stylisticTypeChecked,
// Other configs...
],
languageOptions: {
parserOptions: {
project: ['./tsconfig.node.json', './tsconfig.app.json'],
tsconfigRootDir: import.meta.dirname,
},
// other options...
},
},
])
You can also install eslint-plugin-react-x and eslint-plugin-react-dom for React-specific lint rules:
// eslint.config.js
import reactX from 'eslint-plugin-react-x'
import reactDom from 'eslint-plugin-react-dom'
export default defineConfig([
globalIgnores(['dist']),
{
files: ['**/*.{ts,tsx}'],
extends: [
// Other configs...
// Enable lint rules for React
reactX.configs['recommended-typescript'],
// Enable lint rules for React DOM
reactDom.configs.recommended,
],
languageOptions: {
parserOptions: {
project: ['./tsconfig.node.json', './tsconfig.app.json'],
tsconfigRootDir: import.meta.dirname,
},
// other options...
},
},
])
