# recipes/translated-site/browser.d.ts One file of [`recipes/translated-site`](/docs/recipes/translated-site), at commit `9a5bb24`. ```ts // The browser globals this recipe's page and its Chromium callbacks name, declared loosely. // // `main.ts` runs in Node and its `addInitScript` and `evaluate` callbacks run in Chromium, so the // file has to typecheck without the DOM library while the browser supplies the real objects. // `entry.tsx` runs in the browser outright. Narrow shapes, so a typo is still caught. interface RecipeNode { readonly nodeType: number; readonly nodeName: string; contains(node: unknown): boolean; } declare const document: { readonly readyState: string; readonly body: RecipeNode | null; createElement(tag: string): RecipeNode; }; interface RecipeMutation { readonly target: RecipeNode; readonly addedNodes: ArrayLike & Iterable; readonly removedNodes: ArrayLike & Iterable; } declare const MutationObserver: { new(callback: (records: readonly RecipeMutation[]) => void): { // The document itself, because an init script runs before the parser has made . observe(target: unknown, options: { childList?: boolean; subtree?: boolean }): void; }; }; ```
