About

What is Revise.js?

Revise.js is a foundational JavaScript library designed to simplify the development of contenteditable-based web text editors. It addresses the complexities of working with the native `contenteditable` attribute by offering key building blocks: a `<content-area>` web component that reads the DOM as a clean string value, an algebraic `Edit` data structure for describing and manipulating text changes, and a declarative component model. This library enables developers to build highly customized rich-text editing experiences without the overhead of full-fledged editor frameworks. It supports features like undo/redo history, collaborative editing, and stable keys for line-based rendering, making it ideal for creating robust and flexible text editing solutions.

Best used for

Ideal for developers who need to build custom rich-text editors, implement advanced text manipulation, and enable collaborative editing features. Especially valuable for those seeking a lightweight, modular alternative to heavyweight editor libraries, offering fine-grained control over `contenteditable` elements.

FAQs

What problem does Revise.js solve for contenteditable?

Revise.js addresses the notorious difficulties of working with the `contenteditable` HTML attribute by providing a standard library of building blocks. It offers a reliable way to read the DOM as a string, manage text changes algebraically, and integrate with modern web frameworks, abstracting away browser inconsistencies and complex DOM mutations.

How does Revise.js handle text changes for features like undo/redo?

Revise.js introduces an `Edit` data structure that compactly describes transformations between strings. This structure allows for operations like applying, composing, inverting, and transforming edits, forming the foundation for robust undo/redo history, real-time collaboration, and other features requiring precise change tracking.

Is Revise.js a full-fledged rich-text editor with a UI?

No, Revise.js is not a full-fledged editor with toolbars or a built-in UI. Instead, it provides the foundational building blocks and a declarative component model for developers to create their own custom rich-text editors. It relies on the developer's chosen framework to perform DOM mutations and render the UI.
