What languages does the Prettier formatter support?

JavaScript, TypeScript, JSX, TSX, HTML, CSS, SCSS, Less, JSON, JSON5, Markdown, YAML, GraphQL and Angular/Vue templates — the same languages supported by the official Prettier library.

Is this the real Prettier library?

Yes. GoChronos runs the actual Prettier library compiled to WebAssembly in your browser. The output is identical to running Prettier from the command line or VS Code extension.

Can I configure formatting options like print width or tab size?

Yes. Options including print width, tab width, semi-colons, single vs double quotes, trailing commas and bracket spacing can be configured before formatting.

Is my code uploaded to any server?

No. All formatting runs entirely in your browser via WebAssembly. Your code never leaves your device.
