RDX
Reactive Document eXpressions: Components as Data, not Code.
What it does
The Big Idea MDX changed the game for documentation, but it has a massive Achilles' heel: Security. Because MDX allows arbitrary JavaScript and import statements, you can’t safely let untrusted users author content. Enter RDX. RDX is a strictly typed, declarative document format built as a superset of CommonMark. It gives you the power of rich, interactive components () with the security of a pure data format. No eval(), no JavaScript runtime, and zero risk of XSS.

- DJDatagridxl2.js – Fast Excel-like data table library2022 · datagridxl.com · ▲301
I'm Robbert, the creator of DataGridXL.js. Last month I released version 2 which includes many new features. DataGridXL is a free (and commercial) editable data table library written in ES6. My goal is to develop the most performant & user-friendly spreadsheet-like data table out there: - It has zero dependencies. You don’t need any framework to use DataGridXL. - It is lightweight (~250kb) and easy to use. It does not even require messing with CSS. - It has its own Virtual DOM implementation to prevent DOM errors. - Developer friendly. Supports all modern web browsers Please take a look at…

- OSOpen-source .docx editor library for building document appsMay 2026 · github.com · ▲107
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.

Hi, HN. Gui, Lucis, and the deco.cx team here — we're a bunch of Brazilians building an open-source, all-in-one web editor for the modern TypeScript dev.
