嗨，HN！我独自开发这个项目已经大约三年半了。我尝试过每一个新的项目/笔记工具（如 Notion、Asana、Trello 等），但总是回到简单的文本文件。我想要一种在初次接触时感觉像文本编辑器，但在需要时能够发展成真正结构的工具。 [https://lightwave.so](https://lightwave.so) 技术栈包括 Laravel、MySQL、Redis，以及在客户端手动编写的 JavaScript。没有使用 React/Vue 等框架，约 270 行 jQuery（在超过 8 万行的总代码中）用于一些遗留的 DOM 工具，另外还使用 IndexedDB 进行本地持久化。实时协作采用混合方式：HTTP/2 POST 用于可靠操作 + 通过 Laravel Reverb 的 WebSockets 实现实时光标、在线状态和编辑。这是一项预发布的压力测试，而不是正式发布。Lightwave 将会是一个付费产品。现在我开放它是因为单独测试无法模拟真实流量带来的冲击。上面的链接有一个按钮，可以一键创建测试账户。已知问题：光标和选择系统是从零开始构建的（像 VS Code，而不是 contenteditable 包装），所以有很多需要改进的地方。一些键盘快捷键可能缺失。仅限桌面使用，尚未实现无障碍功能。我正在实时发布修复。如果出现问题，应用内有一个“提交错误或反馈”的按钮。很高兴回答有关架构或其他任何问题。一些亮点： - 粘贴 Markdown，获取原生块。复制块，获取 Markdown。 - 层次化文档结构。层次化文件管理器。 - 实时协作，带有共享光标、选择和在线状态。 - 带语法高亮的代码块。LaTeX 数学块。 - 完整的数据导出：Markdown、JSON 和附件。无锁定。 - 完整的撤销/重做功能，并可恢复光标位置。

Hi HN!I've been building this solo for about three and a half years. I kept trying every new project/notes tool (Notion, Asana, Trello, etc.) and always ended up back in a plain text file. I wanted something that felt like a text editor on first touch but could grow into real structure when you needed it.<a href="https://lightwave.so" rel="nofollow">https://lightwave.so</a>The tech stack is Laravel, MySQL, Redis, and hand-rolled JavaScript on the client. No frameworks like React/Vue/etc. ~270 lines of jQuery (out of 80k+ total LOC) for a few legacy DOM utilities, plus IndexedDB for local persistence. Real-time collaboration uses a hybrid approach: HTTP/2 POST for resilient ops + WebSockets via Laravel Reverb for live cursors, presence, and edits.This is a pre-release stress test, not a launch. Lightwave will be a paid product. Right now I'm opening it up because no amount of solo testing replicates getting punched in the mouth by real traffic.The link above has a button to create a test account in 1 click.Known rough edges: the cursor and selection system are built from scratch (like VS Code, not a contenteditable wrapper), so there's a lot of surface area. Some keyboard shortcuts may be missing. Desktop only, accessibility not yet implemented. I'm shipping fixes in real time.There's a "Submit Bug or Feedback" button inside the app if something breaks. Happy to answer any questions about the architecture, or anything else.Some highlights:- Paste markdown in, get native blocks. Copy blocks out, get markdown back.- Hierarchical document, structure. Hierarchichal file manager.- Live collab with shared cursors, selection, and presence.- Code blocks with syntax highlighting. LaTeX math blocks.- Full data export: markdown, JSON, and attachments. No lock-in.- Full undo/redo with cursor restoration.
