If you’re looking to generate stunning Open Graph images and social cards, Satori is here to help you transform your HTML and CSS into SVG effortlessly. In this guide, we’ll walk through the essentials of using Satori in your project and provide tips for troubleshooting common issues.

Getting Started with Satori

Satori utilizes JSX syntax, allowing you to create SVG images with your HTML and CSS. Imagine being able to design a masterpiece in a familiar canvas of web development while leaving the complexities of SVG rendering to Satori.

Basic Usage

To start using Satori, you can import the library and use it as shown below:

import satori from 'satori';

const svg = await satori(
  { 
    type: 'div', 
    props: {
      children: 'Hello, world',
      style: { color: 'black' },
    }, 
    options: {
      width: 600, 
      height: 400,
      fonts: [
        {
          name: 'Roboto',
          data: robotoArrayBuffer,
          weight: 400,
          style: 'normal',
        },
      ],
    },
  }
);

In the above example, we send a JSX object to Satori, which processes and renders it into a 600×400 SVG. This is like asking a skilled painter to create a portrait based on your provided sketch and color palette.

Necessary Parameters

• Type: The type of HTML element you want (like div).
• Props: Contains children, style, and any other attributes.
• Options: Specify dimensions and font information.

Working with Fonts

Satori supports various font formats including TTF, OTF, and WOFF. Be sure to provide the font data either as an ArrayBuffer (for web) or a Buffer (for Node.js). This enables Satori to render text with your desired fonts seamlessly.

await satori(
  { 
    type: 'div',
    props: { 
      children: 'Hello, world', 
      style: { fontFamily: 'Inter' }, 
    }, 
    options: { 
      width: 600, 
      height: 400, 
      fonts: [
        { name: 'Inter', data: inter, weight: 400, style: 'normal' },
        { name: 'Inter', data: interBold, weight: 700, style: 'normal' },
      ],
    },
  }
);

Images and Backgrounds

You can embed images using the img tag within your Satori-generated SVG. It’s best to specify the width and height attributes. You can also use base64 encoded images to avoid extra IO.

await satori(
  { 
    type: 'img', 
    props: { 
      src: 'data:image/png;base64,...', 
      width: 200, 
      height: 300 
    },
  }
);

Troubleshooting Common Issues

While using Satori might seem straightforward, you may run into some hiccups. Here are a few troubleshooting tips:

• Font Not Showing: Ensure that you correctly load fonts as ArrayBuffer and pass them to Satori.
• Image Issues: Make sure your image URLs are correct and that they link to valid resources.
• SVG Not Rendering Properly: Check your JSX structure to ensure it’s properly formatted and adheres to Satori’s requirements.
• Debugging: Use debug: true option to view your output’s bounding box, which will help in diagnosing layout issues.
