Some while ago, I discussed about self-made custom CMS, which is in an essence, markdown editor; and also real-time feeder.
Recently, I updated my another repo as well.
It does have some features beyond markdown compiler (on web browsers' side), including
- Metadata scraping (which needs CORS bypass, which is usually a backend, including https://cors-anywhere.herokuapp.com)
- Image storage (which needs a backend, also popularly connected to S3 storage.)
I also want to say that webcomponents and shadow roots are godsend. Otherwise, isolated CSS environment would not be possible.
And, I also realized that VSCode can have extended markdown features, but I couldn't find a way to export them, in particular, Admonition.
