OpenAI Node.js Library

The OpenAI Node.js library provides convenient access to the OpenAI API from Node.js applications. Most of the code in this library is generated from our OpenAPI specification.

Important note: this library is meant for server-side usage only, as using it in client-side browser code will expose your secret API key. See here for more details.

Installation

$ npm install openai

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("text-davinci-001", {
  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(
  "text-davinci-001",
  {
    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("text-davinci-001", {
    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);
  }
}
