Zako Tap SDK js

This is the javascript sdk package required to create a javascript tap server responsible for the audio of zako, a discord audio bot.

Quickstart Example

First, you need to download tap-sdk-js on your project.

npm install tap-sdk-js
Copy

Then, you can use the sdk. Here is some example.

import { createClient } from "tap-sdk-js";

const client = createClient({
  name: "your zako tap server name",
  token: "your zako tap server token",
  zakoEndpoint: "zako endpoint (default is https://api.zako.ac)",
});

client.events.on("ready", () => {
  console.log("ready");
});

client.events.on("request", (handle) => {
  const { data, parameters } = handle;
  // data is the actual data to handle.

  // to respond the stream
  handle.respond(/* stream here */);

  // call this on error
  handle.respondError("error message");
});

client.events.on("connectionError", (e) => {
  console.error(e);
});

client.events.on("error", (e) => {
  console.error(e);
});

client.connect();
Copy

Client Description

1. Create Client and Connect

You can create tap server client by call createClient function in tap-sdk-js package.

You should put the client data written as ZakoTapConfig type inside the argument of createClient.

You can then connect to the tab server using client.connect().

import { createClient } from "zako-sdk-js"

const client = createClient({
    name: "your zako tap server name",
    token: "your zako tap server token",
    zakoEndpoint: "zako endpoint (option)"
    backoffBaseMs: "loop waiting time (option)";
});

client.connect();
Copy

2. Client Event

Using the client created above, you can use client.on to perform a specific function when the EventEmitter's event is called.

client.events.on("event name", function)
Copy

The types of events are specified in TapEvents among the types in the zakotap package.

Tap Events

• ready: This event is called when the zako tap server successfully connects to the zako tap hub.
• request: This event is called when an audio request is received from the zako tap hub.
• connectionError: This event is called when an connection error occurs within the zakotap package.
• error: This event is called when an error occurs within the zakotap package.

3. Send Audio

You can send your audio stream by using handle.respond() function.

handle.respond("your audio stream");
Copy

You can get audio request handle from request event parameter. If you don't send an audio stream, your tap server will be considered offline and you may be disconnected.
