The single-connection barrier from the last round was correct and was being bypassed. shutdown_broadcaster() popped the broadcaster out of the registry and only then awaited its teardown, so while the socket was still closing the slot sat empty: a /camera/stream request landing in that window minted a broadcaster with no predecessor and dialled port 6000 immediately. A page reload fires /camera/stop and the new stream request concurrently, so a P1S ended up holding two connections, kept feeding the orphan, and starved the live viewer until its TCP keepalive reaped the dead one ~20 min later. The stopped broadcaster now stays in the registry so the successor chains behind its socket close. The camera page also rendered the <img> src before the stream token arrived whenever auth was disabled, then swapped it once the token landed — aborting the in-flight request and issuing a second one. With auth off both reached the backend, so every load attached two viewers to a one-socket printer. The src now waits for the token query to settle. Subscribers only checked for client disconnect after yielding a frame or on a 30s idle timeout, so a viewer that left during a black stream stayed counted — and /camera/stop trusts that count to decide whether to tear the upstream down.
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 Babel (or oxc when used in rolldown-vite) for Fast Refresh
- @vitejs/plugin-react-swc uses SWC for Fast Refresh
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...
},
},
])
