Zed

Formatting is already wired up for the theme’s toolchain in .zed/settings.json.

PHP

PHP formats via Mago, run through Composer’s vendor/bin/mago format --stdin-input --stdin-filepath {buffer_path} — Mago’s official Zed integration recipe. No extra extension is needed for PHP.

JavaScript, TypeScript, JSON, CSS

These languages route through Zed’s Biome language server instead of the default Prettier formatter. Prettier is explicitly excluded for these languages in .zed/settings.json to avoid the two fighting over the same files.

One manual step

Unlike VS Code, Zed has no workspace-level “recommended extensions” file to auto-prompt for this. Install the Biome extension yourself: open the extension picker with zed: extensions and search for “Biome”.

SCSS and HTML

These still use Zed’s built-in Prettier support, matching the scoped Prettier setup described in SCSS and Getting started.
