I'm building a static site with Astro and trying to create a custom code block component that allows users to switch between different programming languages.
Current Implementation
CodeBlock.jsx:
import React, { useState } from "react";
import "./CodeBlock.css";
import { Code } from 'astro:components';
const CodeBlock = ({ snippets = [] }) => {
if (!snippets.length) return null;
const [activeTab, setActiveTab] = useState(snippets[0].label);
const [collapsed, setCollapsed] = useState(false);
const activeSnippet = snippets.find((s) => s.label === activeTab) || snippets[0];
return (
<div className="code-block">
<div className="code-block-header">
<div className="tabs">
{snippets.map((s) => (
<button
key={s.label}
className={`tab ${activeTab === s.label ? "active" : ""}`}
onClick={() => setActiveTab(s.label)}
>
{s.label}
</button>
))}
</div>
<button
className="collapse-btn"
onClick={() => setCollapsed((prev) => !prev)}
>
{collapsed ? "Expand" : "Collapse"}
</button>
</div>
{!collapsed && (
<pre className="code-content">
<code>{activeSnippet.code}</code>
</pre>
)}
</div>
);
};
export default CodeBlock;
Usage in MDX
import CodeBlock from "../../components/CodeBlock/CodeBlock.jsx"
<CodeBlock client:load
snippets={[
{ label: "Python", code: "print('Hello World')" },
{ label: "Java", code: "System.out.println('Hello, world!');" },
{ label: "JavaScript", code: "console.log('Hello, world!');" }
]}
/>
I'm aware that Astro allows customization of how code blocks are rendered (via remark/rehype plugins or custom components), but my specific challenge is that my component needs to accept multiple code blocks simultaneously to enable the tab-switching functionality. This makes it difficult to leverage standard markdown code block syntax directly.
Is there a way to leverage markdown's native code block syntax (triple backticks) while still having the ability to switch between languages in the UI? For example, something like:
:::tabs
```python
def hello():
print("Hello World")
```
```javascript
function hello() {
console.log("Hello World");
}
```
:::
What's the recommended approach in Astro for creating tabbed/switchable code blocks that work well with MDX content, especially when dealing with multiple code snippets that need to be passed together? Something like this:
Any guidance or best practices would be greatly appreciated! Thanks in advance.
