Description

I was trying to use SuperDoc for a project and kept running into limitations. Customisation was harder than expected and the performance was not where I needed it. So I decided to build my own editor called HawkDoc, using Claude as a coding assistant for a large part of the development.HawkDoc is focused on fast document editing with zero-lag typing. Many editors re-render large parts of the UI on every keystroke or ship heavy dependencies just to support basic formatting. I wanted something simpler and faster.Tech stack:- Lexical (Meta) as the editor engine. Its node-based architecture avoids full re-renders during formatting operations.- Yjs + Hocuspocus for real-time collaboration using CRDTs, allowing conflict-free document syncing.- Redis + PostgreSQL for storage. Yjs deltas are first written to Redis and flushed to Postgres every 30 seconds so the database does not receive keystroke-level writes.- React + TypeScript for the frontend UI.- @react-pdf/renderer for client-side PDF export with watermark support.What works today:- Block based editor- Slash commands- Template variable injection (`{{variable_name}}` rendered as styled chips)- Image uploads- Markdown, HTML, and PDF export- Auto-save- Selection bubble menuWhat is still in progress:- Real-time collaboration UI- Document workspace and file list- DOCX import- Version history- Authentication UI (JWT backend already implemented)Claude Code helped speed up a lot of the early development, especially when building the editor integrations and export pipeline. I would be interested to hear how others are using AI assistants when building new developer tools.The project is MIT licensed and open for feedback and contributions.GitHub: [https://github.com/hawk-doc/hawkdoc](https://github.com/hawk-doc/hawkdoc)
