`node-red-contrib-static-markdown` seems to provide the exact functionality I need but I am facing a little issue:
I have cloned the github repository:
- [https://github.com/TotallyInformation/node-red-contrib-static-markdown](https://github.com/TotallyInformation/node-red-contrib-static-markdown)
so that I can test that the markdown in the example folder `docs/test-md-library` is properly rendered.
This seems to be the case for the [index.md](https://github.com/TotallyInformation/node-red-contrib-static-markdown/blob/master/docs/test-md-library/index.md) but not for the [test.md](https://github.com/TotallyInformation/node-red-contrib-static-markdown/blob/master/docs/test-md-library/test.md) in same folder.
So this is what I get when navigating to test.md:
same error copy pasted as text:
```auto

```
Note that it seems to be working fine for [index.md](https://github.com/TotallyInformation/node-red-contrib-static-markdown/blob/master/docs/test-md-library/index.md). So when navigating to [http://127.0.0.1:1880/md](http://127.0.0.1:1880/md) or [http://127.0.0.1:1880/md/index.md](http://127.0.0.1:1880/md/index.md) : I am seeing the following page:

I think it is a markdown library compatibiity issue that is described in
- [https://github.com/arve0/markdown-it-attrs/issues/90](https://github.com/arve0/markdown-it-attrs/issues/90)
as I am getting the same error for my file `test2.md` with following content:
```auto
This is a paragraph of text with a *highlighted*{.hi} word in it.
```
It gives error
```auto

I guess/hope this also means that the bulk of the markdown will work and that there is only an issue when using special markdown.

I have also reported this issue in the github repository
- [https://github.com/TotallyInformation/node-red-contrib-static-markdown/issues/7](https://github.com/TotallyInformation/node-red-contrib-static-markdown/issues/7)
