How to install

npm install --save gatsby-transformer-remark gatsby-remark-prismjs gatsby-remark-prismjs-copy-button

How to use

1. Add it to gatsby-config.js:

   ※ NOTE: You MUST add gatsby-remark-prismjs-copy-button before gatsby-remark-prismjs, as gatsby-remark-prismjs will transform Code MarkdownASTs to HTML. So gatsby-remark-prismjs-copy-button will unable to find the Code MarkdownASTs to add copy button.

   module.exports = {
     plugins: [
       {
         resolve: `gatsby-transformer-remark`,
         options: {
           plugins: [
             `gatsby-remark-prismjs-copy-button`,
             `gatsby-remark-prismjs`,
           ],
         },
       },
     ],
   };

2. In your template.js.

   export const query = graphql`
     query ($slug: String!) {
       markdownRemark(fields: { slug: { eq: $slug } }) {
         html
       }
     }
   `;
   
   export default function Template({ data }) {
     return (
       <div dangerouslySetInnerHTML={{ __html: data.markdownRemark.html }} />
     );
   }

3. Overwrite the style of the copy button.

   You can overwrite the style of the copy button by adding the following class to your own style.css.

   .gatsby-remark-prismjs-copy-button-container {
     left: 0;
     padding-right: 8px;
   }
