Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

🗣️ Voices

List all your available voices with voices().

import { ElevenLabsClient } from "elevenlabs";

const elevenlabs = new ElevenLabsClient({
    apiKey: "YOUR_API_KEY", // Defaults to process.env.ELEVENLABS_API_KEY
});
const voices = await elevenlabs.voices.getAll();

For information about the structure of the voices output, please refer to the official ElevenLabs API documentation for Get Voices.

🚿 Streaming

Stream audio in real-time, as it's being generated.

const audioStream = await elevenlabs.generate({
    stream: true,
    voice: "Bella",
    text: "This is a... streaming voice",
    model_id: "eleven_multilingual_v2",
});

stream(audioStream);

Retries

This Node SDK is instrumented with automatic retries with exponential backoff. A request will be retried as long as the request is deemed retriable and the number of retry attempts has not grown larger than the configured retry limit (default: 2).

A request is deemed retriable when any of the following HTTP status codes is returned:

  • 408 (Timeout)
  • 409 (Conflict)
  • 429 (Too Many Requests)
  • 5XX (Internal Server Errors)

Use the maxRetries request option to configure this behavior.

const response = await elevenlabs.voices.getAll({}, {
  maxRetries: 2 // Set the maximum number of retries
});

Timeouts

The SDK defaults to a 60 second timout. Use the timeoutInSeconds option to configure this behavior.

const response = await elevenlabs.voices.getAll({}, {
    timeoutInSeconds: 30, // override timeout to 30s
});

Runtime compatiblity

The SDK defaults to node-fetch but will use the global fetch client if present. The SDK works in the following runtimes:

The following runtimes are supported:

  • Node.js 15+
  • Vercel
  • Cloudflare Workers
  • Deno v1.25+
  • Bun 1.0+

Elevenlabs Namespace

All of the ElevenLabs models are nested within the ElevenLabs namespace.

Contributing

While we value open-source contributions to this SDK, this library is generated programmatically. Additions made directly to this library would have to be moved over to our generation code, otherwise they would be overwritten upon the next generated release. Feel free to open a PR as a proof of concept, but know that we will not be able to merge it as-is. We suggest opening an issue first to discuss with us!

On the other hand, contributions to the README are always very welcome!
