wasm-pandoc's Issues

Filters (integrated and external)

Is it technically possible to compile it enabling citeproc (which is integrated)? And external filters (like pandoc-crossref)?

Impressive work, by the way.

npm package?

It’s amazing that someone compiled Pandoc to WebAssembly! Have you considered creating an npm package for it?

hi
can you add support for org format?
thanks

I try to convert docx to html and get errors from terminal, eg. 'JavaScript heap out of memory'.

btw, I convert T.Text to T.Text, like markdown to html, is successful，and I convert BSL.ByteString to T.Text is block by (reader def input)

• docker: mac docker app v4.5.0 (74594)
• nodejs: 16.13.1
• browser: mac chrome v96.0.4664.110
