Show HN: Open-source .docx editor library for building document apps

We are working on an open-source .docx editor library for apps that need to edit Word documents in the browser. We just shipped 1.0.

A lot of existing approaches convert .docx into HTML and lose document semantics along the way. Our editor parses OOXML directly and uses its own rendering+layout engine to produce paged documents with html/css. Edits round-trip back to .docx, so you’re always editing the document, not its representation.

The core rendering engine is framework agnostic, with React and Vue ui adapters on top.

It’s Apache 2.0. Happy to answer questions.

Holy shit, this is exactly what I needed for a major client. The track changes specifically, and being able to do it from Typescript. You have no idea how happy you just made me.

Edit: Did you just make this repo public? Last week I was scouring the internet for something like this and couldn't find it.

Interesting! Would love to check that out as well, have you released it?

Thanks! The hard here part is not typescript implementation but it's catching Word undocumented quirks.

The OOXML spec gets you far but doesn't cover 100% of how Word renders things. Community feedback has helped a lot here, users attach docs (in gh issues) that break rendering, we can reproduce against Word, fix the engine, and keep tightening fidelity.
