Deepgram JavaScript SDK

Static Badge CI npm (scoped) Contributor Covenant

šŸŽÆ Development Setup: This project uses Corepack for package manager consistency. Run corepack enable once, then use pnpm commands normally. See DEVELOPMENT.md for details.

Documentation

You can learn more about the Deepgram API at developers.deepgram.com.

Migrating from earlier versions

V2 to V3

We have published a migration guide on our docs, showing how to move from v2 to v3.

V3.* to V3.4

We recommend using only documented interfaces, as we strictly follow semantic versioning (semver) and breaking changes may occur for undocumented interfaces. To ensure compatibility, consider pinning your versions if you need to use undocumented interfaces.

V3.* to V4

The Voice Agent interfaces have been updated to use the new Voice Agent V1 API. Please refer to our Documentation on Migration to new V1 Agent API.

Installation

You can install this SDK directly from [npm](https://www.npmjs.com/package/@deepgram/sdk).

npm install @deepgram/sdk

or

pnpm install @deepgram/sdk

or

yarn add @deepgram/sdk

UMD

You can now use plain <script>s to import deepgram from CDNs, like:

<script src="https://cdn.jsdelivr.net/npm/@deepgram/sdk"></script>

or even:

<script src="https://unpkg.com/@deepgram/sdk"></script>

Then you can use it from a global deepgram variable:

<script>
  const { createClient } = deepgram;
  const deepgramClient = createClient("deepgram-api-key");

  console.log("Deepgram client instance: ", deepgramClient);
  // ...
</script>

ESM

You can now use type="module" <script>s to import deepgram from CDNs, like:

<script type="module">
  import { createClient } from "https://cdn.jsdelivr.net/npm/@deepgram/sdk/+esm";
  const deepgramClient = createClient("deepgram-api-key");

  console.log("Deepgram client instance: ", deepgramClient);
  // ...
</script>

Initialization

All of the examples below will require createClient.

import { createClient } from "@deepgram/sdk";
// - or -
// const { createClient } = require("@deepgram/sdk");

const deepgramClient = createClient(DEEPGRAM_API_KEY);

Getting an API Key

šŸ”‘ To access the Deepgram API you will need a free Deepgram API Key.

Scoped Configuration

The SDK supports scoped configuration. You'll be able to configure various aspects of each namespace of the SDK from the initialization. Below outlines a flexible and customizable configuration system for the Deepgram SDK. Here's how the namespace configuration works:

Global Defaults

  • The global namespace serves as the foundational configuration applicable across all other namespaces unless overridden.
  • Includes general settings like URL and headers applicable for all API calls.
  • If no specific configurations are provided for other namespaces, the global defaults are used.

Namespace-specific Configurations

  • Each namespace (listen, manage, onprem, read, speak) can have its specific configurations which override the global settings within their respective scopes.
  • Allows for detailed control over different parts of the application interacting with various Deepgram API endpoints.

Transport Options

  • Configurations for both fetch and websocket can be specified under each namespace, allowing different transport mechanisms for different operations.
  • For example, the fetch configuration can have its own URL and proxy settings distinct from the websocket.
  • The generic interfaces define a structure for transport options which include a client (like a fetch or WebSocket instance) and associated options (like headers, URL, proxy settings).

This configuration system enables robust customization where defaults provide a foundation, but every aspect of the client's interaction with the API can be finely controlled and tailored to specific needs through namespace-specific settings. This enhances the maintainability and scalability of the application by localizing configurations to their relevant contexts.

Examples

Change the API url used for all SDK methods

Useful for using different API environments (for e.g. beta).

import { createClient } from "@deepgram/sdk";
// - or -
// const { createClient } = require("@deepgram/sdk");

const deepgramClient = createClient(DEEPGRAM_API_KEY, {
  global: { fetch: { options: { url: "https://api.beta.deepgram.com" } } },
});

Change the API url used for the Voice Agent websocket

Useful for using a voice agent proxy (for e.g. 3rd party provider auth).

import { createClient } from "@deepgram/sdk";
// - or -
// const { createClient } = require("@deepgram/sdk");

const deepgramClient = createClient(DEEPGRAM_API_KEY, {
  global: { websocket: { options: { url: "ws://localhost:8080" } } },
});

Change the API url used for transcription only

Useful for on-prem installations. Only affects requests to /listen endpoints.

import { createClient } from "@deepgram/sdk";
// - or -
// const { createClient } = require("@deepgram/sdk");

const deepgramClient = createClient(DEEPGRAM_API_KEY, {
  listen: { fetch: { options: { url: "http://localhost:8080" } } },
});

Override fetch transmitter

Useful for providing a custom http client.

import { createClient } from "@deepgram/sdk";
// - or -
// const { createClient } = require("@deepgram/sdk");

const yourFetch = async () => {
  return Response("...etc");
};

const deepgramClient = createClient(DEEPGRAM_API_KEY, {
  global: { fetch: { client: yourFetch } },
});

Proxy requests in the browser

This SDK now works in the browser. If you'd like to make REST-based requests (pre-recorded transcription, on-premise, and management requests), then you'll need to use a proxy as we do not support custom CORS origins on our API. To set up your proxy, you configure the SDK like so:

import { createClient } from "@deepgram/sdk";

const deepgramClient = createClient("proxy", {
  global: { fetch: { options: { proxy: { url: "http://localhost:8080" } } } },
});

Important: You must pass "proxy" as your API key, and use the proxy to set the Authorization header to your Deepgram API key.

Your proxy service should replace the Authorization header with Authorization: token <DEEPGRAM_API_KEY> and return results verbatim to the SDK.

Check out our example Node-based proxy here: Deepgram Node Proxy.

Set custom headers for fetch

Useful for many things.

import { createClient } from "@deepgram/sdk";

const deepgramClient = createClient("proxy", {
  global: { fetch: { options: { headers: { "x-custom-header": "foo" } } } },
});

Browser Usage

To use this SDK in the browser, check out UMD and/or ESM initialisation.

Also see proxy requests in the browser if you're planning to make RESTful requests to our API.

Transcription

Remote Files

Transcribe audio from a URL.

const { result, error } = await deepgramClient.listen.prerecorded.transcribeUrl(
  { url: "https://dpgr.am/spacewalk.wav" },
  {
    model: "nova-3",
    // pre-recorded transcription options
  }
);

See our API reference for more info.

Local Files

Transcribe audio from a file.

const { result, error } = await deepgramClient.listen.prerecorded.transcribeFile(
  fs.createReadStream("./examples/spacewalk.wav"),
  {
    model: "nova-3",
    // pre-recorded transcription options
  }
);

See our API reference for more info.

Callbacks / Async

We have a Callback version of both transcribeFile and transcribeUrl, which simply takes a CallbackUrl class.

import { CallbackUrl } from "@deepgram/sdk";

const { result, error } = await deepgramClient.listen.prerecorded.transcribeUrlCallback(
  { url: "https://dpgr.am/spacewalk.wav" },
  new CallbackUrl("http://callback/endpoint"),
  {
    model: "nova-3",
    // pre-recorded transcription options
  }
);

See our API reference for more info.

Live Transcription (WebSocket)

Connect to our websocket and transcribe live streaming audio.

const deepgramConnection = deepgramClient.listen.live({
  model: "nova-3",
  // live transcription options
});

deepgramConnection.on(LiveTranscriptionEvents.Open, () => {
  deepgramConnection.on(LiveTranscriptionEvents.Transcript, (data) => {
    console.log(data);
  });

  source.addListener("got-some-audio", async (event) => {
    deepgramConnection.send(event.raw_audio_data);
  });
});

See our API reference for more info.

Captions

Convert deepgram transcriptions to captions.

import { webvtt, srt } from "@deepgram/sdk";

const { result, error } = await deepgramClient.listen.prerecorded.transcribeUrl({
  model: "nova-3",
  // pre-recorded transcription options
});

const vttResult = webvtt(result);
const srtResult = srt(result);

See our standalone captions library for more information.

Voice Agent

Configure a Voice Agent.

import { AgentEvents } from "@deepgram/sdk";

// Create an agent connection
const deepgramConnection = deepgramClient.agent();

// Set up event handlers
deepgramConnection.on(AgentEvents.Open, () => {
  console.log("Connection opened");

  // Set up event handlers
  deepgramConnection.on(AgentEvents.ConversationText, (data) => {
    console.log(data);
  });

  // other events

  // Configure the agent once connection is established
  deepgramConnection.configure({
    // agent configuration
  });

  // etc...
});

See our API reference for more info.

Text to Speech

Single-Request

Convert text into speech using the REST API.

const { result } = await deepgramClient.speak.request(
  { text },
  {
    model: "aura-2-thalia-en",
    // text to speech options
  }
);

See our API reference for more info.

Continuous Text Stream (WebSocket)

Connect to our websocket and send a continuous text stream to generate speech.

const deepgramConnection = deepgramClient.speak.live({
  model: "aura-2-thalia-en",
  // live text to speech options
});

deepgramConnection.on(LiveTTSEvents.Open, () => {
  console.log("Connection opened");

  // Send text data for TTS synthesis
  deepgramConnection.sendText(text);

  // Send Flush message to the server after sending the text
  deepgramConnection.flush();

  deepgramConnection.on(LiveTTSEvents.Close, () => {
    console.log("Connection closed");
  });
});

See our API reference for more info.

Text Intelligence

Analyze text using our intelligence AI features.

const text = `The history of the phrase 'The quick brown fox jumps over the
lazy dog'. The earliest known appearance of the phrase was in The Boston
Journal...`;

const { result, error } = await deepgramClient.read.analyzeText(
  { text },
  {
    language: "en",
    // text intelligence options
  }
);

See our API reference for more info.

Authentication

Get Token Details

Retrieves the details of the current authentication token.
