YAML Editor

Forms 2

About

Editable code field with dependency-free YAML syntax highlighting, a line-number gutter and tab-to-indent. Controlled or uncontrolled.

Built with React and Tailwind. Copy the prompt and paste it into Claude Code, Cursor or Lovable: your agent adds YAML Editor to your project and fits it to your theme.

Code

How YAML Editor is used: the demo's code. The component's own source comes with a free account.
