node-dalle2
A type safe library for interacting with OpenAI's Dall-E 2 AI.
Dall-E 2 is a new AI system that can create realistic images and art from a description in natural langauge.
Setup
To get access to Dall-E 2's API you need to join the waitlist and wait to be accepted which can be found here.
- To get the your unique session key you need to go to https://labs.openai.com/.
- Open the Network Tab in Developer Tools in your browser.
- Send an image request in the input box.
- In the network tab you'll find a POST request to https://labs.openai.com/api/labs/tasks.
- In the POST request headers you'll find your session key in the "Authorization" header, it'll look something like "sess-xxxxxxxxxxxxxxxxxxxxxxxxxxxx".
Usage
npm i node-dalle2import { Dalle } from "node-dalle2";
// Add Session key
const dalle = new Dalle({ apiKey: "sess-xxxxxxxxxxxxxxxxxxxxxxxxxxxx" });
// Create an async function
const getDalle2Images = async (caption) => {
// Call the Dall-e 2 API
const response = await dalle.generate(caption);
// If Dall-e 2 couldn't generate images from the given caption
if (!response) {
console.error(
"Dall-e 2 couldn't generate images based upon the given caption."
);
return null;
}
// Get the image array from the response object
const { data } = response;
// Return the image array
return data;
};Calling the function using top level await
// Using top level await
const data = await getDalle2Images("Man in a suit riding a horse during the medieval times");
// If the image array is empty for some reason
if (!data) {
console.error("Something has gone horribly wrong...");
}
// Log the image array
console.log(data);Calling the function using .then syntax
getDalle2Images("Man in a suit riding a horse during the medieval times")
.then((data) => {
// If the image array is empty for some reason
if (!data) {
console.error("Something has gone horribly wrong...");
return null;
}
// Log the image array
console.log(data);
})
// Log the error if one occurs
.catch((err) => {
console.error(err);
});Output
