'Copy to clipboard' buttons are an excellent way to improve the accessibility of code snippets, particularly on mobile devices. The final result should look similar to the Copy button for the code snippets on this post (minus the styling). This visitor function should be added to the list of existing Rehype plugins, in the case of Contentlayer, it's the file. To traverse the node tree, we'll use the visit function from the unist-util-visit package. We'll store this text content on the pre node itself. To begin, we need to create a visitor function that traverses the node tree of the content and extracts the unmodified (raw text) content from all code elements nested inside the pre tag. I originally came across this idea on a Twitter thread and slightly adapted the code to fit our use case. This content can then be accessed as props inside our custom MDX component that renders the copy button. We can extract the unstyled code content before the syntax highlighting stage and append it as a property to the code nodes. Thankfully, there's a better way to achieve our objective. However, this approach is inefficient as it would require undoing everything that Rehype Pretty Code has done for us. One potential solution is to parse the code content when copying it, removing all HTML markup.

By the time we intend to render the button on the client side, the code content will already be wrapped in various tags necessary for syntax highlighting. Rendering the button in our case presents a challenge since the syntax highlighting is executed on the server side. If you want to improve the discoverability of your Next.js website, I have written an article about adding a sitemap to it: Add a Dynamic Sitemap to Next.js Website Using Pages or App Directory Extracting the code content

Let's dive in! Setting upĪs usual, we need to install the required dependencies. In fact, this blog uses the exact functionality we'll be creating, so you can see the result in action. By the end of this post, you'll be able to streamline code sharing and enhance the user experience on your Next.js website. We'll be using Next.js 13+ with the 'app' directory enabled.

This tutorial will guide you on how to create a 'copy to clipboard' button for the code snippets processed with Rehype Pretty Code, a popular Rehype plugin for syntax highlighting in an MDX-based Next.js website.

However, if you're using MDX in your Next.js application, there is no one-size-fits-all solution for implementing a 'copy to clipboard' button. Some code highlighting libraries include this functionality, either built-in or through a plugin. This feature is especially useful on mobile devices, providing users with a fast and straightforward method of sharing code fragments without the need to select text manually.

Many websites make code sharing more accessible by adding a 'copy to clipboard' button to their code snippets. perhaps these suggestions are trying to fix some other issue with scrolling / anchors or their bugs are rooted in the custom app as it was in my case.įinally, previously mentioned events document.Code sharing is an essential aspect of modern web development, enabling developers to collaborate and learn from each other. I trust that original bug was fixed and provided that assumption is correct, this GH issue should be fixed to prevent more confusion trust other suggested solutions mainly around using setTimeout or employing other 3rd party packages for a simple scroll fix are not optimal. To be clear I never experienced the explicit js error described in the original issue above. hence it was a very custom source of app bug in my case. In regard to my earlier comments and my particular case - the culprit was custom auth logic which delayed DOM rendering on some pages which in turn prevented scroll-to-anchor behaviour on SSR pages.
