Code Editor Input Group for Svelte

A code box named script.js, with refresh above the text and Line 1, Column 1 plus Run below.

UI library: Ark UI

A tall textarea framed like a small editor. The header shows a file icon, script.js, and a refresh button. The footer shows Line 1, Column 1 and a Run button. The position does not follow the cursor, and there is no highlighting.

Use it for a short snippet someone can edit and run. If you only need the text, use a Textarea. In Svelte, Ark UI does not track the cursor or highlight the code.

FAQ

How is the header built?

An InputGroupAddon with align="block-start" and border-b: an InputGroupText with a file icon and script.js in font-mono, and an icon-only Refresh button pushed to the end with ms-auto.

Why is the footer before the header in the code?

Order between addons doesn't matter: align places each one. Only the textarea needs to come first.

Does Line 1, Column 1 follow the cursor?

No, it's fixed text. Compute it from the textarea's selection start on select and key events.

Is this a code editor?

It's a textarea: no syntax highlighting or tab indentation. Use it for short snippets, or put an editor library in the same frame.

How is the textarea labeled?

aria-label="Code"; the Refresh button is named by its own aria-label.
