Migrating from v2

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

Installation

You can install this SDK directly from npm.

npm 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 _deepgram = createClient("deepgram-api-key");

  console.log("Deepgram Instance: ", _deepgram);
  // ...
</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 deepgram = createClient("deepgram-api-key");

  console.log("Deepgram Instance: ", deepgram);
  // ...
</script>

Initialization

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

const deepgram = createClient(DEEPGRAM_API_KEY);

Getting an API Key

🔑 To access the Deepgram API you will need a free Deepgram API Key.

Scoped Configuration

A new feature is scoped configuration. You'll be able to configure various aspects of the SDK from the initialization.

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

const deepgram = createClient(DEEPGRAM_API_KEY, {
  global: { url: "https://api.beta.deepgram.com" },
  // restProxy: { url: "http://localhost:8080" }
});

Rest 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 deepgram = createClient("proxy", {
  restProxy: { 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.

Transcription (Synchronous)

Remote Files

const { result, error } = await deepgram.listen.prerecorded.transcribeUrl(
  {
    url: "https://dpgr.am/spacewalk.wav",
  },
  {
    model: "nova",
  }
);

See our API reference for more info.

Local Files

const { result, error } = await deepgram.listen.prerecorded.transcribeFile(
  fs.createReadStream("./examples/spacewalk.wav"),
  {
    model: "nova",
  }
);

or

const { result, error } = await deepgram.listen.prerecorded.transcribeFile(
  fs.readFileSync("./examples/spacewalk.wav"),
  {
    model: "nova",
  }
);

See our API reference for more info.

Transcription (Asynchronous / Callbacks)

Remote Files

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

const { result, error } = await deepgram.listen.prerecorded.transcribeUrlCallback(
  {
    url: "https://dpgr.am/spacewalk.wav",
  },
  new CallbackUrl("http://callback/endpoint"),
  {
    model: "nova",
  }
);

See our API reference for more info.

Local Files

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

const { result, error } = await deepgram.listen.prerecorded.transcribeFileCallback(
  fs.createReadStream("./examples/spacewalk.wav"),
  new CallbackUrl("http://callback/endpoint"),
  {
    model: "nova",
  }
);

or

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

const { result, error } = await deepgram.listen.prerecorded.transcribeFileCallback(
  fs.readFileSync("./examples/spacewalk.wav"),
  new CallbackUrl("http://callback/endpoint"),
  {
    model: "nova",
  }
);

See our API reference for more info.

Transcription (Live / Streaming)

Live Audio

const dgConnection = deepgram.listen.live({ model: "nova" });

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

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

To see an example, check out our Node.js example or our Browser example.

See our API reference for more info.

Transcribing to captions

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

const { result, error } = await deepgram.listen.prerecorded.transcribeUrl(
  {
    url: "https://dpgr.am/spacewalk.wav",
  },
  {
    model: "nova",
  }
);

const vttOutput = webvtt(result);
// const srtOutput = srt(result);

Debugging and making changes locally

If you want to make local changes to the SDK and run the examples/, you'll need to npm run build first, to ensure that your changes are included in the examples that are running.
