Image Generation with OpenAI DALL·E 3 & SvelteKit! ⏱️ Chrono App ? LIVE Coding & Chill

Introduction

Hello everyone and welcome to another exciting session of live coding and chill! I’m your host Johnny, thrilled to be here with you. I hope you’ve had an amazing week and are gearing up for an even better Friday and weekend.

In today’s event, we’re diving into the innovative world of image generation using OpenAI's DALL·E 3 within our Chrono App—a tool designed to assist creators like myself in optimizing YouTube streaming and efficiency on the platform. This might be one of the simplest apps we've worked on, implementing various AI and LLM features. Today’s goal is to add image generation capabilities that suggest thumbnails based on our content agenda.

The Agenda for Today

Yesterday, OpenAI announced the release of another model that improves upon reasoning and problem-solving over longer contexts. This new model can create complex applications like a snake game almost instantly (within 5 minutes, which would take me months!). Although we won't be creating a game today, we'll leverage the OpenAI API to generate some thumbnail images, creating a more effective content strategy for our streams.

To accomplish this, we’ve integrated the OpenAI API directly instead of relying on the Vercel SDK, which currently does not support features returning generated images. We'll explore OpenAI's powerful image generation API, which allows us to experiment with different designs and thumbnails for our videos.

Recapping the Chrono App Features

Before diving into image generation, let’s recap some core functionalities of the Chrono App:

1. User Authentication: Users log in using Google, facilitating streamlined access.

2. Live Stream Creation: Each live stream can have a personalized agenda that users can easily edit. These agendas persist in a Turo SQLite database, enhancing user experience.

3. Thumbnails and Text Suggestions: Users can request suggestions for video descriptions and, as of today, thumbnails too!

We also have a user-friendly interface where users can add or delete agenda items as desired. Here's what we’ll be adding today:

Thumbnail Generation Button

We’re adding a new button named "Generate Thumbnails" that will call our newly created API endpoint for thumbnail suggestions based on the live stream agenda. This button will be rendered on the UI and interact with our backend to retrieve generated thumbnails efficiently.

Implementing OpenAI’s Image Generation

To generate images, we'll leverage OpenAI’s image generation API. We’ll create an express middleware that requests DALL·E 3 generated images based on user prompts, returning an array of image URLs for easy display within the application. Here’s a brief breakdown of the steps:

1. Setup OpenAI Client: We’ll install OpenAI’s official Node implementation and set it up within the app.

2. Create API Endpoints: Develop an endpoint designed to accept prompts for thumbnail generation and request images from OpenAI. This endpoint will return the resulting image URLs to be displayed to the user.

3. Render Thumbnails: The newly generated images will be displayed in a user-friendly manner, with options for users to download them directly.

Download Feature

For user convenience, we'll add a download button to each thumbnail image generated, allowing users to save these thumbnails quickly. This will utilize the data URL format for images, making downloads efficient and straightforward.

Feature Flag Implementation

To ensure a smooth user experience, we’ll implement feature flags. This allows us to toggle the thumbnail generation functionality on or off without extensive redeployment. This is useful for testing and will help prevent overwhelming the app with excessive requests or issues from still-in-development features.

Exploring the Results

Today’s session has demonstrated the ability to create better and more customized visual content for streams using AI. As we develop further, we’ll look into refining our prompts and experimenting with various styles to cater to our unique needs.

Thanks to everyone who joined in today’s live stream! I sincerely appreciate your participation, questions, and insights. It’s always a pleasure to share knowledge while coding together. Have a fantastic weekend, and see you on Tuesday!
