Vite 5.4 import.meta.env VITE_ variables exposed to client source bundled documentation
💡 Result:
In Vite 5.4, environment variables are exposed to client-side source code through the special import.meta.env object [1][2]. Key mechanics for this exposure include: 1. VITE_ Prefix Requirement: By default, Vite only exposes environment variables prefixed with VITE_ to your client-side source code [1][3]. This design is intended to prevent the accidental leakage of sensitive environment variables (such as API keys or database passwords) into the client bundle [1][4]. Any variables without this prefix remain inaccessible via import.meta.env [3][4]. 2. Static Replacement: During the build process, Vite statically replaces references to import.meta.env.VITE_SOME_VAR with the actual string value defined in your environment files [1][3]. Because these values are inlined into your JavaScript bundle at build time, they are visible to anyone inspecting the client-side code [3][5]. Consequently, you should never store sensitive secrets (like private keys) in VITE_ prefixed variables [4][5]. 3. Development vs. Production: Vite loads environment variables from.env files based on the current mode (e.g.,.env.production for the build command or.env.development for the dev server) [1][6]. 4. TypeScript Support: To receive IntelliSense for your custom VITE_ variables, you can augment the ImportMetaEnv interface within a type declaration file (e.g., src/vite-env.d.ts) [1][2]: /// interface ImportMetaEnv { readonly VITE_YOUR_VARIABLE: string // Add other variables here } interface ImportMeta { readonly env: ImportMetaEnv } If you need to access environment variables within your vite.config.ts file, you cannot use import.meta.env, as the configuration file is evaluated in a Node.js environment before these files are loaded [3]. Instead, you should use the loadEnv helper function exported by Vite [7][3].

Issue short-lived TURN credentials from the backend
When production sets these VITE_ variables, Vite inlines them into browser assets, and TeamDebateRoom.tsx passes them to RTCIceServer. Users can extract reusable credentials and abuse the relay. Issue short-lived, authenticated credentials per session from the backend. (vite.dev)

Keep currentTranscript scoped to its source phase.
TeamDebateRoom stores one currentTranscript value, updates it from liveTranscript, and does not clear it when debatePhase changes. The fallback can therefore display interim text from the previous phase in the new phase. Store the source phase with the transcript or clear currentTranscript on each phase transition.

Separate room membership from media readiness.
ensureMediaStream() catches getUserMedia() failure, but ws.onopen still sends "join". handleTeamJoin then broadcasts participantJoined. Existing peers start negotiation without a stream-ready joiner: the lower-ID peer sends an offer that the joiner cannot answer, while the higher-ID peer does not initiate.
isCameraOnRef starts as true, so the first camera click after failure requests disablement, skips media acquisition, and returns. Send a separate media-ready signal only after a stream exists, broadcast participantJoined from that signal, and retry acquisition when camera enable is requested without a stream. Cover the first-failure/second-success flow for both user-ID orderings.

Do not report inactive speech recognition as active.
This label appears whenever micControlState is "on". Speech recognition can be unsupported or disabled after a permission error. Users then see an incorrect active status.
