An image generator using OpenAI's DALL-E.

import OpenAI from "openai"

import {
  title,
  textInput,
  select,
  textarea,
  checkbox,
  range,
  launchApp,
  buildApp,
} from "../index.js"

const openai = new OpenAI({ apiKey: process.env.OPENAI_API_KEY })

const ui = [
  title("My example app"),
  textInput({ name: "Name", defaultValue: "A peaceful beach at sunset" }),
  select({
    name: "Style",
    options: ["Realistic", "Cartoon", "Abstract", "Vintage", "Futuristic"],
  }),
  textarea({ name: "AdditionalDetails", defaultValue: "Add a small cat" }),
  checkbox({ name: "IncludeCharacters" }),
  range({ name: "Brightness", min: 1, max: 10, defaultValue: 5 }),
]

const onSubmit = async ({
  ImageDescription,
  Style,
  AdditionalDetails,
  IncludeCharacters,
  Brightness,
}) => {
  const prompt = `
    ImageDescription: ${ImageDescription}
    Style: ${Style}
    Brightness: ${Brightness}
    IncludeCharacters: ${IncludeCharacters}
    AdditionalDetails: ${AdditionalDetails} 
  `

  const response = await openai.images.generate({
    model: "dall-e-3",
    prompt,
    n: 1,
    size: "1024x1024",
  })

  return response.data[0].url
}

const app = buildApp({ ui, onSubmit, outputType: "image" })

launchApp(app)

Result will be:
