Parse, check, export

A TypeScript library with no runtime dependencies. Diagnostics never throw.

const { recipe, diagnostics } =
  check(source);
const json = toJson(recipe);

Drop a card in any page

The <brew-recipe> element renders the sheet, styled with plain CSS variables.

import "@brewlang/render/element";

<brew-recipe
