Text layout system in JavaScript similar to Google Docs?

I’m looking for a JavaScript-based text layout system that works like the one in Google Docs. Does anyone know if something like this is available?

I’ve heard that Google Docs uses some pretty advanced techniques to make their editor work smoothly. They don’t use the usual stuff like designMode or contentEditable. Microsoft’s Office Online seems to do something similar.

I’m curious if there’s a library or framework out there that can handle text layout in a similar way. I want to create a document editor that’s as smooth and responsive as Google Docs, but I’m not sure where to start.

Has anyone worked with or come across a JavaScript solution that could help with this kind of text layout? Any tips or suggestions would be really helpful!

const editor = new AdvancedEditor();
editor.init({
  container: document.getElementById('editor-container'),
  customLayout: true,
  paragraphStyles: ['normal', 'heading1', 'heading2'],
  inlineStyles: ['bold', 'italic', 'underline']
});

editor.onTextChange((text) => {
  console.log('Text updated:', text);
});

This is just a rough idea of what I’m imagining. Any insights would be great!

I’ve been down this road before, and it’s quite a challenge. Google Docs’ text layout system is indeed sophisticated. While I haven’t found an exact replica, I can suggest a few alternatives that might get you close.

ProseMirror is a powerful framework that offers similar functionality. It’s highly customizable and provides a solid foundation for building complex editors. Another option worth exploring is Quill.js, which offers a rich text editor with good performance.

For a more low-level approach, you might want to look into Canvas-based rendering. This gives you more control over text layout but requires more work to implement advanced features.

Remember, replicating Google Docs’ performance and features is a significant undertaking. You might need to combine multiple libraries or build custom components to achieve your desired result. Good luck with your project!

I’ve actually worked on a similar project recently, and I can tell you it’s quite the challenge. One library that really stood out to me was Tiptap. It’s built on top of ProseMirror, which JumpingMountain mentioned, but it’s more developer-friendly in my experience.

Tiptap offers a lot of the features you’re looking for out of the box, like custom paragraph styles and inline formatting. It’s also extensible, so you can build more complex functionality if needed. The performance is pretty solid too, though not quite at Google Docs level.

Another approach you might consider is using a virtual DOM for rendering, combined with a custom layout engine. This can give you more control over the rendering process and potentially better performance, but it’s definitely more work upfront.

Whatever route you choose, be prepared for a lot of edge cases and browser inconsistencies. Text layout is deceptively complex, especially when you start dealing with things like RTL languages or Asian character sets. It’s a fascinating problem space though - good luck with your project!
