Looking good. One important thing. One small thing. One stylistic thing!

      '}',
      'function MDXContent(props = {}) {',
-      '  const {wrapper: MDXLayout} = props.components || ({});',
+      '  const _component0 = "a-b", {wrapper: MDXLayout} = props.components || ({});',


Same here as above?

Ah, I think I understand this prop a bit better now. Looks like I didn't implement this right! I'll rework 👍

Sweet, thanks!
You could also likely set it on that destructuring object, alongside wrapper: MDXLayout? You may need to set a computed field in the AST or so though 🤔: https://astexplorer.net/#/gist/702f0315bf76ddbaf45a0928b0b06e96/784539f882835483b4541f9eff8d81ec4a327733

-            ] of invalidComponentNameToVariable) {
+              _componentsId,
+              _componentName
+            ] of idToInvalidComponentName) {


I still kinda like name, value better, but I’m not blocking on this.
I feel a bit more strongly about not using _ to start variable names, that is often used with variables (parameters) to mark them as explicitly not used

Understood, removed those _s! I also tried using name and value, but noticed it leads to {value: name} and {name: value} in the sections where they're used. It... kinda made my head spin, so I chose [id, componentName] instead 😆

Released in 2.1.3!

bholmesdev · 2022-08-17T18:55:56Z

@wooorm Woo! Thanks for the thorough review and feedback here. Already learned a ton about the MDX project ❤️

This fixes a bug, uncovered in #2112 and in #2123, which is rather unlikely to occur. It only occurs when: 1. Custom elements (such as `<a-b></a-b>`) are injected (not authored) into a tree 2. Either: 1. A layout component is defined within an MDX document 2. A provider is used, and any component is defined within MDX documents In those cases, an accidental `const ;` was injected into the final serialized document. Which caused anything trying to run the code to crash. The problem was introduced in 9904838, the commit message of which sheds some light on why custom elements are peculiar and need extra handling. We track which component contains which other components. If some component uses `<A />`, then some code to handle `A` is injected in that component. If a different component uses `<B />`, some code for `B` is injected inside it. But the components don’t need to know about what’s used in other components. This mechanism had a mistake for custom elements: they were tracked globally. This commit fixes that, by tracking them scoped to the component that includes them. Related-to: GH-2100. Related-to: GH-2101. Closes GH-2112. Closes GH-2123. Co-authored-by: Caleb Eby <[email protected]> Co-authored-by: bholmesdev <[email protected]>
