Praxis CI 7b1b296430 feat(P01-02-05,P01-02-06): React client + latency readout
client/ — React + Vite + TypeScript scaffolded with the Pipecat client SDK
(@pipecat-ai/client-js) and SmallWebRTCTransport
(@pipecat-ai/small-webrtc-transport). useVoiceSession.ts hook manages mic
permission, WebRTC connect, audio playback, live transcript, and a latency
readout (captures the e2e_latency_ms metric the server emits). App.tsx is a
minimal one-page session UI: disclaimer, Start/End buttons, status badge,
latency readout (within/over 600ms budget), live transcript. vite.config.ts
proxies /pipecat + /health to the Python server (port 8789). npm run
typecheck + npm run build pass.

server/latency.py — LatencyObserver (a Pipecat FrameProcessor) timestamps
transcript-ready, LLM-first-token, TTS-first-audio, and playback-start per
turn, computes ASR→TTS-first-audio (the v0.1 latency target), and logs it
to console with a within/over-budget verdict. Wired into the pipeline
between STT/LLM/TTS so it observes without altering the frame stream. 5
unit tests pass (LatencyRecord e2e math + observer construction +
reset_turn). Full server suite: 18 passed.

# React + TypeScript + Vite
This template provides a minimal setup to get React working in Vite with HMR and some Oxlint rules.
Currently, two official plugins are available:
- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react) uses [Oxc](https://oxc.rs)
- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react-swc) uses [SWC](https://swc.rs/)
## 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](https://react.dev/learn/react-compiler/installation).
## Expanding the Oxlint configuration
If you are developing a production application, we recommend enabling type-aware lint rules by installing `oxlint-tsgolint` and editing `.oxlintrc.json`:
```json
{
"$schema": "./node_modules/oxlint/configuration_schema.json",
"plugins": ["react", "typescript", "oxc"],
"options": {
"typeAware": true
},
"rules": {
"react/rules-of-hooks": "error",
"react/only-export-components": ["warn", { "allowConstantExport": true }]
}
}
```
See the [Oxlint rules documentation](https://oxc.rs/docs/guide/usage/linter/rules) for the full list of rules and categories.
