Groq Node API Library

This library provides convenient access to the Groq REST API from server-side TypeScript or JavaScript.

The REST API documentation can be found on console.groq.com. The full API of this library can be found in api.md.

Installation

npm install groq-sdk

Usage

The full API of this library can be found in api.md.

import Groq from 'groq-sdk';

const groq = new Groq();

async function main() {
  const chatCompletion = await groq.chat.completions.create({
    messages: [{ role: 'user', content: 'Explain the importance of low latency LLMs' }],
    model: 'mixtral-8x7b-32768',
  });

  console.log(chatCompletion.choices[0].message.content);
}

main();

Request & Response types

This library includes TypeScript definitions for all request params and response fields. You may import and use them like so:

import Groq from 'groq-sdk';

const groq = new Groq();

async function main() {
  const params: Groq.Chat.CompletionCreateParams = {
    messages: [
      { role: 'system', content: 'You are a helpful assisstant.' },
      { role: 'user', content: 'Explain the importance of low latency LLMs' },
    ],
    model: 'mixtral-8x7b-32768',
  };
  const chatCompletion: Groq.Chat.ChatCompletion = await groq.chat.completions.create(params);
}

main();

Documentation for each method, request param, and response field are available in docstrings and will appear on hover in most modern editors.

Handling errors

When the library is unable to connect to the API, or if the API returns a non-success status code (i.e., 4xx or 5xx response), a subclass of APIError will be thrown:

async function main() {
  const chatCompletion = await groq.chat.completions
    .create({
      messages: [
        { role: 'system', content: 'You are a helpful assisstant.' },
        { role: 'user', content: 'Explain the importance of low latency LLMs' },
      ],
      model: 'mixtral-8x7b-32768',
    })
    .catch(async (err) => {
      if (err instanceof Groq.APIError) {
        console.log(err.status); // 400
        console.log(err.name); // BadRequestError
        console.log(err.headers); // {server: 'nginx', ...}
      } else {
        throw err;
      }
    });
}

main();

Error codes are as followed:

Retries

Certain errors will be automatically retried 2 times by default, with a short exponential backoff. Connection errors (for example, due to a network connectivity problem), 408 Request Timeout, 409 Conflict, 429 Rate Limit, and >=500 Internal errors will all be retried by default.

You can use the maxRetries option to configure or disable this:

// Configure the default for all requests:
const groq = new Groq({
  maxRetries: 0, // default is 2
});

// Or, configure per-request:
await groq.chat.completions.create({ messages: [{ role: 'system', content: 'You are a helpful assisstant.' }, { role: 'user', content: 'Explain the importance of low latency LLMs' }], model: 'mixtral-8x7b-32768' }, {
  maxRetries: 5,
});

Timeouts

Requests time out after 1 minute by default. You can configure this with a timeout option:

// Configure the default for all requests:
const groq = new Groq({
  timeout: 20 * 1000, // 20 seconds (default is 1 minute)
});

// Override per-request:
await groq.chat.completions.create({ messages: [{ role: 'system', content: 'You are a helpful assisstant.' }, { role: 'user', content: 'Explain the importance of low latency LLMs' }], model: 'mixtral-8x7b-32768' }, {
  timeout: 5 * 1000,
});

On timeout, an APIConnectionTimeoutError is thrown.

Note that requests which time out will be retried twice by default.

Advanced Usage

Accessing raw Response data (e.g., headers)

The “raw” Response returned by fetch() can be accessed through the .asResponse() method on the APIPromise type that all methods return.

You can also use the .withResponse() method to get the raw Response along with the parsed data.

const groq = new Groq();

const response = await groq.chat.completions
  .create({
    messages: [
      { role: 'system', content: 'You are a helpful assisstant.' },
      { role: 'user', content: 'Explain the importance of low latency LLMs' },
    ],
    model: 'mixtral-8x7b-32768',
  })
  .asResponse();
console.log(response.headers.get('X-My-Header'));
console.log(response.statusText); // access the underlying Response object

const { data: chatCompletion, response: raw } = await groq.chat.completions
  .create({
    messages: [
      { role: 'system', content: 'You are a helpful assisstant.' },
      { role: 'user', content: 'Explain the importance of low latency LLMs' },
    ],
    model: 'mixtral-8x7b-32768',
  })
  .withResponse();
console.log(raw.headers.get('X-My-Header'));
console.log(chatCompletion.id);

Customizing the fetch client

By default, this library uses node-fetch in Node, and expects a global fetch function in other environments.

If you would prefer to use a global, web-standards-compliant fetch function even in a Node environment, (for example, if you are running Node with --experimental-fetch or using NextJS which polyfills with undici), add the following import before your first import from "Groq":

// Tell TypeScript and the package to use the global web fetch instead of node-fetch.
// Note, despite the name, this does not add any polyfills, but expects them to be provided if needed.
import 'groq-sdk/shims/web';
import Groq from 'groq-sdk';

To do the inverse, add import "groq-sdk/shims/node" (which does import polyfills). This can also be useful if you are getting the wrong TypeScript types for Response (more details).

You may also provide a custom fetch function when instantiating the client, which can be used to inspect or alter the Request or Response before/after each request:

import { fetch } from 'undici'; // as one example
import Groq from 'groq-sdk';

const client = new Groq({
  fetch: async (url: RequestInfo, init?: RequestInit): Promise<Response> => {
    console.log('About to make a request', url, init);
    const response = await fetch(url, init);
    console.log('Got response', response);
    return response;
  },
});

Note that if given a DEBUG=true environment variable, this library will log all requests and responses automatically. This is intended for debugging purposes only and may change in the future without notice.

Configuring an HTTP(S) Agent (e.g., for proxies)

By default, this library uses a stable agent for all http/https requests to reuse TCP connections, eliminating many TCP & TLS handshakes and shaving around 100ms off most requests.

If you would like to disable or customize this behavior, for example to use the API behind a proxy, you can pass an httpAgent which is used for all requests (be they http or https), for example:

import http from 'http';
import { HttpsProxyAgent } from 'https-proxy-agent';

// Configure the default for all requests:
const groq = new Groq({
  httpAgent: new HttpsProxyAgent(process.env.PROXY_URL),
});

// Override per-request:
await groq.chat.completions.create(
  {
    messages: [
      { role: 'system', content: 'You are a helpful assisstant.' },
      { role: 'user', content: 'Explain the importance of low latency LLMs' },
    ],
    model: 'mixtral-8x7b-32768',
  },
  {
    httpAgent: new http.Agent({ keepAlive: false }),
  },
);

Semantic Versioning

This package generally follows SemVer conventions, though certain backwards-incompatible changes may be released as minor versions:

1. Changes that only affect static types, without breaking runtime behavior.
2. Changes to library internals which are technically public but not intended or documented for external use. (Please open a GitHub issue to let us know if you are relying on such internals).
3. Changes that we do not expect to impact the vast majority of users in practice.

We take backwards-compatibility seriously and work hard to ensure you can rely on a smooth upgrade experience.

We are keen for your feedback; please open an issue with questions, bugs, or suggestions.
