This is a Next.js project used to generate Open Graph (OG) images with customizable parameters, such as title, URL, avatar, author, and date. The project uses dayjs to format dates and the useSearchParams hook from next/navigation to retrieve parameters from the URL query string. The generated OG images have a fixed width and height of 1200x630 pixels and feature a gradient background. The default domain is honghong.me, and the generated OG images display the author's avatar, name, title, and publishing date.
