SvelteKit 使用基于文件系统的路由,这意味着你的应用的路由 - 换句话说,当用户导航到特定 URL 时应用应该做什么 - 由你的代码库中的目录定义。
¥SvelteKit uses filesystem-based routing, which means that the routes of your app — in other words, what the app should do when a user navigates to a particular URL — are defined by the directories in your codebase.
src/routes 中的每个 +page.svelte 文件都会在你的应用中创建一个页面。在这个应用中,我们目前有一个页面 — src/routes/+page.svelte,它映射到 /。如果我们导航到 /about,我们将看到 404 Not Found 错误。
¥Every +page.svelte file inside src/routes creates a page in your app. In this app we currently have one page — src/routes/+page.svelte, which maps to /. If we navigate to /about, we’ll see a 404 Not Found error.
让我们修复它。添加第二个页面 src/routes/about/+page.svelte,复制 src/routes/+page.svelte 的内容并更新它:
¥Let’s fix that. Add a second page, src/routes/about/+page.svelte, copy the contents of src/routes/+page.svelte, and update it:
<nav>
<a href="/">home</a>
<a href="/about">about</a>
</nav>
<h1>about</h1>
<p>this is the about page.</p>我们现在可以在 / 和 /about 之间导航。
¥We can now navigate between / and /about.
与传统的多页应用不同,导航到
/about并返回会更新当前页面的内容,就像单页应用一样。这为我们提供了两全其美的效果 - 快速的服务器渲染启动和即时导航。(此行为可以是 configured。)
<nav>
<a href="/">home</a>
<a href="/about">about</a>
</nav>
<h1>home</h1>
<p>this is the home page.</p>
