CodeJar is a lightweight (~2.5 kB), dependency-free embeddable code editor for the browser built on contenteditable. It handles indentation, auto-closing brackets and quotes, Tab key handling, and undo/redo, while letting you plug in any highlighting library like Prism.js or highlight.js.

Use cases

• embed a code editor in a web page
• add a lightweight code input box to a web app
• build an online code playground
• let users edit code snippets in the browser
• create a custom code editor with my own syntax highlighter
• replace CodeMirror with a tiny editor

When to choose

• you need a tiny, dependency-free code editor in the browser
• you want full control over syntax highlighting via your own highlight function
• you need basic editing features like auto-indent, bracket closing, and undo/redo without a heavyweight editor

When to avoid

• you need advanced IDE features like code folding, linting, or multi-cursor editing
• you need a full-featured editor with built-in language grammars and autocomplete
• you are building a non-browser (desktop or mobile-native) editor
