(By serving the default page at the route, this file acts in a similar role to index.jsx in other frameworks.) In other words, +page.svelte is just a standard Svelte component following normal Svelte syntax.Īlthough +page.svelte is just a front-end Svelte component, it can rely on other special files to do its work. (All other files will be ignored, so you can put helper files in the same directories.)Įach page is a Svelte component, defined in a +page.svelte file. A file at /src/routes/foo/bar/+page.svelte becomes the web page at localhost:5173/foo/bar, defined by the Svelte component created in that file. These file types begin with a plus sign (+), indicating that they have a special significance for the framework. Several file conventions within the directories define the pages and endpoints. Subdirectories map to the URL path, so /src/routes/foo/bar becomes localhost:5173/foo/bar. SvelteKit’s root directory is /src/routes (by default). So /src/routes corresponds to the root URL, for example localhost:5173/ in the browser. How are the front-end pages and back-end endpoints defined?Īt the heart of every application framework is the routing engine, which associates the code that generates the pages to the URLs in the browser. Most JavaScript frameworks like SvelteKit have settled into the general layout that Next.js uses, wherein the files and directories are mapped to the URL path.How are back-end routes accessed by the front end?.How are URLs mapped to front-end pages and back-end endpoints?.The nature of a full-stack application framework is that it must be able to unite the front-end and back-end of your application under a single umbrella. A full-stack framework must answer these questions: Svelte is a front-end reactive framework, comparable to React or Vue at a high level, but with its own angle on things. SvelteKit is the full-stack application framework for Svelte, along the lines of Next or Nuxt, but again with its own conventions. As recently announced, SvelteKit has arrived at its much anticipated 1.0 milestone, following a long beta. SvelteKit 1.0 brings a fully realized application framework for building full-stack JavaScript applications with Svelte front ends. Let’s take a look.
