gen-img: A Single-Page Web App to Generate Images with Dall-E 3

I've been itching to play around with Go and HTMX 🤩, so I figured, why not build a simple web app with them? Plus, I've been needing to generate AI images every now and then—like for this blog post's cover image. Instead of generating one image at a time and picking through them manually, I thought it'd be way more convenient to build a little app that spits out a bunch of options at once and lets me easily pick the best one.

How to Run

1. Clone the repository and go to the project directory:

git clone https://github.com/Isaac-Fate/gen-img.git
cd gen-img

2. Install the dependencies:

go mod download

3. Create a .env file and add your OpenAI API key:

cp .env.example .env

Fill in the .env file with your OpenAI API key.

4. Run the application:

go run cmd/web/main.go

Since this ptoject uses Gin framework, you may run it in the realse mode setting the GIN_MODE environment variable to release:

GIN_MODE=release go run cmd/web/main.go

Also, you may also change the default port (8080) by setting the PORT environment variable:

PORT=8081 go run cmd/web/main.go

5. Visit http://localhost:8080 (or the port you set) in your browser.
