+### init
+
+This function runs once, when the server is created or the app starts in the browser, and is a useful place to do asynchronous work such as initializing a database connection.
+
+> [!NOTE] If your environment supports top-level await, the `init` function is really no different from writing your initialisation logic at the top level of the module, but some environments — most notably, Safari — don't.
+
+```js
+/// file: src/hooks.server.js
+import * as db from '$lib/server/database';
+
+/** @type {import('@sveltejs/kit').ServerInit} */
+export async function init() {
+	await db.connect();
+}
+```
+
+> [!NOTE]
+> In the browser, asynchronous work in `init` will delay hydration, so be mindful of what you put in there.

 ## Universal hooks
 
 The following can be added to `src/hooks.js`. Universal hooks run on both server and client (not to be confused with shared hooks, which are environment-specific).

+A navigation interceptor that triggers before we navigate to a URL, whether by clicking a link, calling `goto(...)`, or using the browser back/forward controls.
 
 Calling `cancel()` will prevent the navigation from completing. If `navigation.type === 'leave'` — meaning the user is navigating away from the app (or closing the tab) — calling `cancel` will trigger the native browser unload confirmation dialog. In this case, the navigation may or may not be cancelled depending on the user's response.
