OpenAI API in node gives basic Await error. How do I fix?

Question

I literally copied the code from the openAI example and it gives me a remedial Await JS error but I am unsure what it expects me to do. I just want to spin up an Express.js instance and get a hello world from openapi (eventually chatgpt). The web server works fine.

Here is my doinker:

const express = require('express')
const app = express()


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

const configuration = new Configuration({
  apiKey: "my key is here"
});
const openai = new OpenAIApi(configuration);

const completion = await openai.createCompletion({
  model: "text-davinci-002",
  prompt: "Hello world",
});
console.log(completion.data.choices[0].text);



app.get('/', function (req, res) {
  res.send('Hello World')
})

app.listen(3000)

Error:

SyntaxError: await is only valid in async functions and the top level bodies of modules

The original OpenAI example code is the same. Why the hell is this the example code?

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-002",
  prompt: "Hello world",
});
console.log(completion.data.choices[0].text);

Answer 1

As already mentioned, you need to wrap your async code in a function:

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

const configuration = new Configuration({
  apiKey: "my key is here"
});

const openai = new OpenAIApi(configuration);

const completionFunction = async () => {
  const completion = await openai.createCompletion({
    model: "text-davinci-002",
    prompt: "Hello world",
  });
  
  console.log(completion.data.choices[0].text);
};

completionFunction();

app.get('/', function (req, res) {
  res.send('Hello World')
})

app.listen(3000)

Also, make sure you have a package.json file with the appropriate dependencies:

{
  "name": "sample",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "author": "",
  "license": "ISC",
  "dependencies": {
    "express": "^4.18.2",
    "openai": "^3.1.0"
  }
}
