This is a Sanity Studio v3 plugin for generating OG images.

Based on sanity-plugin-asset-source-ogimage for Sanity Studio v2

This Sanity plugin provides a tool to generate Open Graph (OG) images for your Sanity documents. It's designed to be flexible, allowing you to define custom layouts for the generated images.

• Custom Layouts: Craft your own layouts for the images.
• Live Preview: Witness changes in real-time as you tweak the layout and content.
• Download & Generate: Create the image and either download it instantly or integrate it within your Sanity documents.

🚨 You need @sanity 3.5.0 or greater and react 18.0.0 or greater

npm install @catherineriver/sanity-plugin-generate-ogimage

Use it in sanity.config.ts (or .js):

import {defineConfig} from 'sanity'
import {generateOGImage} from 'sanity-plugin-generate-ogimage'

export default defineConfig({
  //...
  plugins: [generateOGImage()],
})

Use it as source on a single type

{
    name: 'ogImage',
    title: 'OG image',
    type: 'image',
    options: {
      sources: [
        {
          name: 'sharing-image',
          title: 'Generate Image',
          component: (props) => (
            <MediaEditor {...props} darkMode={true} layouts={[OgImageEditorLayout]} />
          ),
        },
      ],
  }
}

You can define custom layouts for your generated images. A layout is essentially a React component that receives certain props and renders the desired output.

Here's a basic structure of a layout:

import React from "react";
import { LayoutData } from "sanity-plugin-generate-ogimage/types";

const MyCustomLayout: React.FC<LayoutData> = ({ title, subtitle, logo }) => {
  // Your rendering logic here
};

export default MyCustomLayout;

To use your custom layouts, modify your sanity.config.ts (or .js) as follows:

import {defineConfig} from 'sanity'
import {generateOGImage} from 'sanity-plugin-generate-ogimage'
import MyCustomLayout from './path-to-your-layout'

export default defineConfig({
  // ... other config
  plugins: [generateOGImage({layouts: [MyCustomLayout]})],
})

Here's a brief overview of the main components in the repository:

• Editor: The main editor component where users can select a layout, modify content, and generate the image.
• Image: A utility component to display Sanity images.
• LayoutsPicker: Allows users to pick from multiple available layouts.
• EditorField: Represents individual fields in the editor, like text inputs, switches, etc.
• useEditorLogic: A custom hook that encapsulates the logic for generating and downloading the image.
• imageBuilder: A utility to build image URLs using Sanity's image URL builder.
