openai-web v3.2.1

OpenAI Javascript Library

The OpenAI javascript library provides a browser compatible javascript library for convenient access to the OpenAI API. This is an unofficial fork of the OpenAI library with modifications for browser and extension compatibility. The library is using "fetch" instead of XHR requests to make API calls, making it compatible with browser extensions.

This library is intended to be used when you want to give the user ability to use their own API keys and directly make requests from the browser. This can be used for HTML apps that run in the browser or browser extensions.

You can look at ChatGPT Rewriter extension to see how it can be used in a Chrome extension.

Important note: Don't embed your API keys in the browser. Always ask the user for their API keys.

Installation

npm install openai-web

Usage

The library needs to be configured with your account's secret key, which is available on the website. We recommend setting it as an environment variable. Here's an example of initializing the library with the API key loaded from an environment variable and creating a completion:

const { Configuration, OpenAIApi } = require("openai");

const configuration = new Configuration({
  apiKey: process.env.OPENAI_API_KEY,
});
const openai = new OpenAIApi(configuration);

const completion = await openai.createCompletion({
  model: "text-davinci-003",
  prompt: "Hello world",
});
console.log(completion.data.choices[0].text);

Check out the full API documentation for examples of all the available functions.

Request options

All of the available API request functions additionally contain an optional final parameter where you can pass custom axios request options, for example:

const completion = await openai.createCompletion(
  {
    model: "text-davinci-003",
    prompt: "Hello world",
  },
  {
    timeout: 1000,
    headers: {
      "Example-Header": "example",
    },
  }
);

Error handling

API requests can potentially return errors due to invalid inputs or other issues. These errors can be handled with a try...catch statement, and the error details can be found in either error.response or error.message:

try {
  const completion = await openai.createCompletion({
    model: "text-davinci-003",
    prompt: "Hello world",
  });
  console.log(completion.data.choices[0].text);
} catch (error) {
  if (error.response) {
    console.log(error.response.status);
    console.log(error.response.data);
  } else {
    console.log(error.message);
  }
}

Streaming completions

Streaming completions (stream=true) are not natively supported in this package yet, but a workaround exists if needed.

Upgrade guide

All breaking changes for major version releases are listed below.

3.0.0

• The function signature of createCompletion(engineId, params) changed to createCompletion(params). The value previously passed in as the engineId argument should now be passed in as model in the params object (e.g. createCompletion({ model: "text-davinci-003", ... }))
• Replace any createCompletionFromModel(params) calls with createCompletion(params)

Thanks

Thank you to ceifa for creating and maintaining the original unofficial openai npm package before we released this official library! ceifa's original package has been renamed to gpt-x.
