CodeMirror is an extensible code editor component for the web, implemented as a set of modular npm packages providing syntax highlighting, autocompletion, and rich editing features. This repository is the central development monorepo holding the bug tracker and development scripts for the project's packages.
Use cases
- embed a code editor in a web page
- add syntax highlighting to a text input field
- build a browser-based IDE or code playground
- support collaborative editing in a web app
- add autocompletion and linting to an in-browser editor
- customize editor themes and keybindings like vim or emacs
When to choose
- you need a lightweight, modular code editor component in the browser
- you want fine-grained control over editor features via an extension API
- you need good accessibility, mobile support, and performance on large documents
When to avoid
- you need a full standalone desktop IDE rather than an embeddable component
- you want a batteries-included editor without assembling multiple packages
- you are looking for a plain textarea replacement with no editing features
