@evex/zeta

Runtime-agnostic TypeScript API client for Zeta. The library uses Web standard APIs such as fetch, Headers, Blob, FormData, ReadableStream, TextDecoder, and crypto.randomUUID, so it can run on modern JavaScript runtimes without depending on Bun.

---

import { ZetaClient } from "@evex/zeta";

const client = new ZetaClient({
  token: "<access-token>",
  refreshToken: "<refresh-token>",
  deviceId: "<device-id>",
  userLanguage: "ENGLISH",
  onTokenUpdate(tokens) {
    // Persist tokens wherever your application stores secrets.
    console.log("refreshed", tokens.accessToken, tokens.refreshToken);
  },
});

const me = await client.profile.me();
const freshTokens = await client.refreshTokens();

const talk = await client.talk.create({ plotId: "plot-id" });
const stream = await talk.sendTextMessage("Hello");
for await (const event of stream) {
  console.log(event.data.event, event.data.chunkMessage?.contents);
}

await talk.delete();

Runtime requirements

• Node.js 18+.
• Bun 1+.
• Deno 1.39+.
• Browser and edge runtimes with Web Fetch API support.
• For older runtimes, pass a compatible fetch implementation with new ZetaClient({ fetch }).
