gatsby-embedder-excalidraw

This custom transformer for gatsby-remark-embedder allows you to embed Excalidraw diagrams in Markdown content simply by pasting an Excalidraw link in the source.

The code for this library is lifted from this directory in the excalidraw-blog Gatsby site. All credit for this transformer goes to those authors. I was inspired to do this when I saw Alex Luong's tweet about making this functionality into a gatsby-remark-excalidraw plugin.

// gatsby-config.js
module.exports = {
  plugins: [
    {
      resolve: 'gatsby-transformer-remark',
      options: {
        plugins: [
          {
            resolve: 'gatsby-remark-embedder',
            options: {
              customTransformers: [require('gatsby-embedder-excalidraw')]

        ]
      }
    }
  ]
};

Example

This guide will show you how to get up and running with gatsby-embedder-excalidraw in the fewest steps possible. It uses gatsby-plugin-mdx to take advantage of its awesome default behaviour of automatically creating pages based on MDX files in src/pages.

Install dependencies

First, install gatsby and its dependencies:

npm install gatsby react react-dom

Next, install gatsby-plugin-mdx and its dependencies:

npm install gatsby-plugin-mdx @mdx-js/mdx @mdx-js/react

Configure plugins

Add gatsby-plugin-mdx to your Gatsby config:

// gatsby-config.js
module.exports = {
  plugins: [
    {
      resolve: 'gatsby-plugin-mdx'
    }
  ]
};

Install the gatsby-remark-embedder plugin and this Excalidraw transformer gatsby-embedder-excalidraw:

npm install gatsby-remark-embedder gatsby-embedder-excalidraw

Add gatsby-remark-embedder as a Gatsby remark plugin for gatsby-plugin-mdx. In your gatsby-remark-embedder options, add gatsby-embedder-excalidraw as a custom transformer:

// gatsby-config.js
module.exports = {
  plugins: [
    {
-     resolve: 'gatsby-plugin-mdx'
+     resolve: 'gatsby-plugin-mdx',
+     options: {
+       gatsbyRemarkPlugins: [
+         {
+           resolve: 'gatsby-remark-embedder',
+           options: {
+             customTransformers: [require('gatsby-embedder-excalidraw')]
+           }
+         }
+       ]
+     }
    }
  ]
};

Create a drawing

Head over to Excalidraw and draw something! Once you're satisfied, you can find a shareable link to your drawing in the export dialog, accesible from the icon in the top left corner of the page.

Embed your drawing

Create an MDX page at src/pages/index.mdx and add a link to an Excalidraw diagram:
