I think this is good, but I also think we could improve it slightly.
Also, would you add a test here: https://github.com/readmeio/markdown/tree/next/__tests__/migration
lib/migrate.ts
Outdated
| // parsing weird cases. | ||
| .replaceAll(/a/g, 'a') | ||
| // A common issue is that <br> tags are not properly closed | ||
| .replaceAll(/<br(?!\s*\/)\s*>/g, '<br />') |

The most 'correct' way to do this would be to traverse the tree:
Suggested change
| .replaceAll(/<br(?!\s*\/)\s*>/g, '<br />') | |
| import { visit } from 'unist-util-visit'; | |
| visit(ast, 'text', textNode => { | |
| textNode.value = textNode.value.replaceAll(/<br(?!\s*\/)\s*>/g, '<br />') | |
| }) |
This would prevent replacing <br> strings when they're inside inline code or code blocks, eq:
Not a `<br>` tag
```
Also not a <br> tag
```

Thanks for the suggestion, implemented it! Though I've had to use 'html' to visit instead of text for it to work, let me know if that's not right

I've also created a generic function for migration html tags in general in case we want to regex more tags
