    Use Go's HTML/template to write React-like code▲106

    Hi all, I'm currently working on my hobby project, and one of the fun constraints I put in was to build using as less dependencies as possible. I chose Go as it has a really good standard library, and all went well for building backend. But for frontend, I was wondering whether I should break the constraint and go for React.

    Open-source .docx editor library for building document apps▲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.

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.
