Not Work??

[bcz3]

I just tested it and doesn't work

[X7md]

Sorry, but I do not maintain this lib for a long time...

I suggest you to combine those libraries to do the same functionality:

• rehype-rewrite

  {
        rewrite: (node, index, parent) => {
          if(node.tagName == "img") {
            parent.children = [...parent.children, {
              type: 'element',
              tagName: "figcaption",
              // Optional
              properties: {
                class: "text-xs"
              },
              children: [
                {
                  type: "element",
                  tagName: "small",
                  children: [
                    {type: 'text', value: node.properties.alt}
                  ]
                }
              ]
            }]
          }
        }
      }

• rehype-wrap-all

  {
  selector: 'img',
  wrapper: 'figure data-img .text-center'
  }

• remark-unwrap-images (optional)
