Enhanced Developer Experience in Svelte 4

Localized Transitions

Transitions in Svelte 4 are local by default, preventing potential conflicts during page loading.

// Transitions are now local in Svelte 4
let transition = local(/* ... */);

Improved Web Component Authoring

Web Components authoring is simplified with the dedicated customElement attribute in svelte:options.

<svelte:options
  customElement={{
    tag: 'custom-element',
    shadow: 'none',
    props: {
      name: {
        reflect: true,
        type: 'Number',
        attribute: 'element-index'
      }
    }
  }}
/>

Stricter Type Enforcement

Svelte 4 introduces stricter types for createEventDispatcher, Action, ActionReturn, and onMount.

import { createEventDispatcher } from 'svelte';

const dispatch = createEventDispatcher<{
  optional: number | null;
  required: string;
  noArgument: null;
}>();

// Svelte version 3:
dispatch('optional');
dispatch('required'); // I can still omit the detail argument
dispatch('noArgument', 'surprise'); // I can still add a detail argument

// Svelte version 4 using TypeScript strict mode:
dispatch('optional');
dispatch('required'); // error, missing argument
dispatch('noArgument', 'surprise'); // error, cannot pass an argument

These changes collectively offer a streamlined, robust, and efficient coding experience.

Revamped Svelte Websites

With Svelte 4, the team has also revamped its main website, offering an improved and more user-friendly experience.

The Tutorial Website

The Svelte tutorial website has been overhauled for an enhanced learning journey. New improvements include a visible file structure, fewer elements in the navbar, smoother navigation between sections, and a new dark mode.

The Svelte Website

The primary Svelte website received a makeover too, including better mobile navigation, improved TypeScript documentation, and a handy dark mode.

These website updates aim to provide a more engaging, intuitive, and user-friendly experience for all Svelte users.

Introducing the All New SvelteKit and SCSS Kit for starter.dev

Introduction At This Dot Labs, we love Svelte. We've even created a starter.dev kit for SvelteKit that you can use to scaffold your next frontend project using SCSS, TypeScript, Vitest and Storybook. What is starter.dev? Starter.dev helps developers get started building web apps with a variety of frameworks, showcasing how various libraries can fit together to solve similar problems. To do that, This Dot Labs has built a series of showcase apps that recreate the experience of using GitHub. What is SvelteKit? How is it unique? SvelteKit is a full-stack framework that gives you the best of both worlds: the page is server-side rendered on your first visit, but when you navigate to other pages, they are client-side rendered. SvelteKit gives you levers for your pages to use SSR (server-side rendering), CSR (client-side rendering), SSG (static site generation), SPA (single page application) & MPA (multi page application). The core of SvelteKit provides a highly configurable rendering engine. Why SvelteKit and not Svelte? SvelteKit isn’t built on top of Svelte, but it’s a backend web framework where Svelte is used as the view layer. In theory, you could rip it out and replace it with another component framework that supports server-side rendering, and the same is true for other web frameworks. This allows us to deploy everything as a Node server, or even use Vercel and serverless functions. Other reasons to use SvelteKit include: 1. Pages (file based routing) 2. Endpoints (API routes) 3. Nested layouts (way more powerful than just nesting files because the segment of the URL maps to your component hierarchy) 4. Hot module replacement (instant updates in the browser when you make a change preserving application state) 5. Preprocessing (TypeScript, SCSS, and Pug among others) 6. Building component libraries (creating and publishing npm packages) 7. Deployment options (adapters for any platform) Building a SvelteKit showcase presented several challenges given its uniqueness and different approach to building web apps. This blog post details what we chose to include in our SvelteKit GitHub clone, and how we integrated them. Project Structures and Naming Conventions SvelteKit has unique conventions in its project structure and naming conventions. Project Files src This is the meat of the project: - lib contains your library code, which can be imported via the $lib alias, or packaged up for distribution using svelte-package. It can be imported by using the $lib/* alias. - server contains your server-only library code. SvelteKit will prevent you from importing these in client code. - components contain single responsibility components that are imported in our routes. They typically contain three files: .spec.ts for unit tests, .svelte and .stories.ts for storybook stories. Barrel files were not necessary here. - images contains images that can be imported, and used in the project. - stores contains state that needs to be accessed by multiple unrelated components, or by a regular JS module. - styles contains styles that can be imported in our Svelte applications. - params contains any param matchers your app needs - routes contains the routes of your application - app.html is your page template — an HTML document containing the following placeholders: - %sveltekit.head% — link and script elements needed by the app, plus any head content - %sveltekit.body% — the markup for a rendered page. This should live inside a or other element, rather than directly inside the body element, to prevent bugs caused by browser extensions injecting elements that are then destroyed by the hydration process. SvelteKit will warn you in development if this is not the case - %sveltekit.assets% — either paths.assets, if specified, or a relative path to paths.base - %sveltekit.nonce% — a CSP nonce for manually included links and scripts, if used - hooks.server.ts contains your application's hooks static Any static assets that should be served as-is, like robots.txt or favicon.png, go in here. svelte.config.js This file contains your Svelte and SvelteKit configuration. tsconfig.json Since SvelteKit relies on certain configuration being set a specific way, it generates its own .svelte-kit/tsconfig.json file, which your own config extends. vite.config.js A SvelteKit project is really just a Vite project that uses the @sveltejs/kit/vite plugin, along with any other Vite configuration. Routing To get a deep dive of how routing works with SvelteKit, please check out this article. SCSS SvelteKit supports a number of CSS preprocessors. For people who are new to Svelte or SvelteKit, the syntax for using SCSS or SASS is simple, just need to add the lang="sass" attribute to the style tag. ` ` Then add SCSS support with the svelte-preprocess package. ` Why SCSS and not Tailwind? Tailwind CSS has been used by several other starter kits. We otherwise decided to go with SCSS as the syntax is simple and easily understood by even beginners. Vitest Test Driven Development (TDD) is one of the best ways to ensure your code works like it's supposed to work. It can also help you create reliable builds during continuous deployments. Vitest is an up-and-coming testing framework which has similar functionality to Jest. Since we are using Vite as our build tool for Svelte in this kit, Vitest has very good integration with Vite, and offers a similar testing environment without needing extra configuration. To test Svelte components that seemed to be hard to test. Such as two-way bindings, name slots, Context API, etc., we need to add more configuration. We added @testing-library/svelte, jsdom and @testing-library/jest-dom that allow for similar functionality as Jest. ` We ensured the $lib alias is supported in our tests by resolving the alias in our vite.config.ts. We also added a setupTest.ts to add @testing-library/jest-dom matchers & mocks of SvelteKit modules. ` ` If you want to see some test recipes you can use on your SvelteKit projects, check out our SvelteKit-SCSS Github showcase. Storybook Like many of the other starter.dev kits, the SvelteKit starter uses Storybook to interactively view and build components in isolation. For more information on Storybook and SvelteKit visit the article. Linting ESLint and Prettier are useful tools for keeping the project neat and consistent among multiple contributors. To quickly format your project, run: ` Running ESLint and Prettier as part of your git workflow is important because it helps you fail fast. This helps us, as contributors, to have a more consistent production codebase. We achieved this in our SvelteKit-SCSS Github showcase with the help of Husky, lint-staged and Prettier. How does lint-staged work? It's specifically designed to work on "staged" files, which are files you've changed or created, but haven't yet committed to your project. Working on staged files limits the number of files you need to lint at any given time, and makes the workflow faster. We configured lint-staged in our package.json. This runs Prettier pre-commit, and ensures the code is up to our ESLint standards. ` The commands you configure will run "pre-commit". As you're attempting to commit files to your project you'll see ESLint run in your terminal. Once it's done you may have successfully committed, or find yourself with linting errors you need to fix before you're able to commit the code. This works hand-in-hand with husky. Husky uses distinct bash files with filenames that match the workflow step they correspond to, e.g. "pre-commit". ` Running ESLint, or Prettier as part of your git workflow is important because it helps you fail fast, which helps contributors have a more consistent production codebase. Conclusion SvelteKit is a relatively new and novel framework. The structure represents our best judgment of how a basic SvelteKit application should be. We welcome everyone to take a look, and contribute back to the SvelteKit-SCSS and our SvelteKit-SCSS Github showcase if you have any improvements that you would like to propose!...

A Deep Dive into SvelteKit's Rendering Techniques

A Deep Dive into SvelteKit's Rendering Techniques Introduction SvelteKit is a meta-framework for Svelte that allows you to develop pages based on their content. At its core, SvelteKit introduces three fundamental strategies out of the box, each designed to streamline the development process and adapt to the specific needs of your project. These strategies enable you to easily create dynamic, responsive, and highly interactive web applications. These strategies, or as SvelteKit calls them, page options, are: * Prerender: Ideal for static content that doesn't change, making your pages lightning-fast to load. * SSR (Server-Side Rendering): Ideal for rendering full pages with dynamic content from a server. * CSR (Client-Side Rendering): Best for highly dynamic and interactive applications where content updates frequently based on user actions. These page options can be applied to specific pages (when exported from **+page.js or +page.server.js) or to a group of pages (when exported from +layout.js or +layout.server.js). They can also be set across the entire application. You accomplish this by exporting it from the root layout. It's worth noting that child layouts and pages can supersede settings from parent layouts. This means you could activate prerendering for the whole app and then turn it off for certain pages that require dynamic server rendering (SSR). In this blog post, we'll explore these page options and share some insights on how you might use them in everyday web projects. Prerendering Prerendering is akin to taking a snapshot of your web pages when you build your application; you might have heard of this as static rendering. This snapshot is then served to all users, ensuring lightning-fast load times since the server simply delivers the pre-built files without additional processing rather than dynamically generating the files for each request. This method is perfect for content that remains unchanged across visits, such as blog posts, documentation, or landing pages. In other words, pages with no dynamic content. There will be situations where you would like to avoid using this option, though. The rule of thumb is that if two different users will see different content, then this is a no-go. Other reasons are inconvenience for your needs. For example, your build times could drag if you end up prerendering tons of pages. Is that convenient to you? Well, that’s for you to decide! The prerender option is turned off by default, so we need to enable it if we want to start using it. Export the following in the +page.server.js or just +page.js: ` Likewise, if you have a group of pages, you could do the same inside a +layout.js or +layout.server.js . If your app is suitable to be all SSG (Static Side Generation), you could use adapter-static, which will output files suitable for use with any static web server. In cases where you happen to opt-in for this, you could turn off pages that need dynamic rendering: ` Another cool feature about prerendering is that pages that fetch data from server routes can automatically inherit default values during the prerendering process. This feature simplifies data management and enhances the development workflow, especially when dealing with dynamic content that needs to be prerendered with specific data sets. Let's say you have a blog where each post fetches its content from a server route when the page loads. Normally, this would require the user's browser to make a request to the server at runtime. However, with prerendering, you can have this data fetched and embedded into the page at build time. ` In this example, when the blog/[slug].sveltepage is prerendered, it makes a fetch call to /api/posts/[slug], which returns the post data. This data is then used to prerender the blog post page with the content already in place, allowing the page to load instantly for the user, with the blog post content visible even before any JavaScript is executed on the client side. There’s a third and useful option when prerendering: ` Using this option is like telling SvelteKit to make a smart guess about whether to prerender your page in advance. You're saying, "Hey SvelteKit, you decide if this page should be prerendered based on what you find about the page" SvelteKit analyzes your page and if it determines the page can be prerendered without complications, it will automatically generate a prerendered version. This process involves SvelteKit either crawling a link inside an already prerendered page, prerendering entry points or targeting pages that are specifically marked for prerendering set in entries. An example is a blog section where you post articles regularly. The blog section has a main page that lists all your blog posts and individual pages for each blog post. The structure for this might be something like: In this setup, the /blog main entry page will be prerendered automatically. However, individual blog posts at paths like /blog/[slug] will not be prerendered unless linked directly from another prerendered page. For instance, if there’s a link to /blog/some-cool-slug, like: <a href="/blog/some-cool-slug">, SvelteKit will be able to crawl that link and prerender that specific page as well. Now let’s say that you would like to prerender your latest blog post, but there's no link for SvelteKit to crawl to this page. In these cases, you can explicitly add these pages to the prerender entries list. By doing so, SvelteKit will prerender every specified entry, ensuring that the content is immediately accessible to users. You can configure the prerender entries directly in your svelte.config.js file or by exporting an entries function from a +page.js, a +page.server.js or a +server.js belonging to a dynamic route. Here’s how you can do it: ` SSR SSR is similar to prerendering. It ensures that pages are first rendered on the server. This process generates the complete HTML content, which is then sent to the client for hydration). This approach enhances the initial page load performance and SEO, providing a better user experience. Unlike prerendering, where pages are generated at build time, SSR pages are created at runtime. This key difference allows for the generation of dynamic content, making SSR particularly suited for applications that require personalized content for each user or real-time updates, such as user dashboards, e-commerce sites, and social media platforms. Similar to prerendering, SSR comes with its own set of limitations, and there are scenarios where it might not be the best choice for your project: * SSR can be expensive. It can significantly load your server, especially for high-traffic sites, as each page request involves rendering content on the server. If server resources are constrained, this could lead to performance bottlenecks. * Highly Interactive Applications: Applications that rely heavily on user interactions and real-time updates (like games or interactive tools like an admin panel) might not benefit much from SSR. CSR can provide a smoother user experience in these cases, as it minimizes server requests after the initial load. * SEO Is Not YOUR Priority: If search engine optimization isn't a key concern for your project (for example, an internal dashboard or an app behind a login), the SEO benefits of SSR might not justify the additional complexity and server demands. export const ssr = true is the option enabled by default. Thus, we can use its benefits from the start. To execute code exclusively on the server, such as fetching data from a database or an external API, SvelteKit offers a convention using +page.server.js files. This setup is ideal for server-side operations, ensuring sensitive logic and credentials are not exposed to the client. ` Note: When you employ +page.js in SvelteKit, the contained code is executed on both the server and client sides by default. However, if you intend for the code to run exclusively on the client side, you can disable SSR by setting export const ssr = false within your +page.js file. Doing so ensures that the code is only executed in the browser, adhering to client-side rendering principles and turning your app into a SPA. This is useful for cases where you don’t need the load on the server, or you don’t benefit from any of the benefits of SSR. CSR CSR plays a crucial role in making web pages interactive by hydrating them and incorporating JavaScript. JavaScript is crucial for adding interactivity to web pages—everything from animations and video players to form validations and dynamic content updates relies on JavaScript. However, there are instances where JavaScript is unnecessary. Consider a prerendered 'About' page; enabling CSR on this page could be excessive, especially if it lacks interactive elements. In such scenarios, you can streamline your page by disabling CSR that comes enabled by default, which can be done by simply doing this: ` Using this trick smartly can make your web pages load fast because downloading JavaScript is sometimes heavy. The key lies in strategically combining this approach with other rendering techniques to optimize performance and user experience. One factor to consider, though, is that turning off CSR also means you'll lose client-side routing. This requires you to depend on traditional browser navigation instead. Conclusion By thoughtfully applying these strategies, you can craft a SvelteKit application that performs exceptionally and delivers a fantastic user experience tailored to your audience's needs. Wrapping up our journey through SSR with SvelteKit. We discovered how choosing the right way to render pages (like prerendering, SSR, or CSR) is super important and can make a big difference in how well a website works. SvelteKit is awesome because it lets you pick the best method for your website. So, remember, playing with SvelteKit and these rendering methods can make your websites stand out. Use it to build websites that not only work great but are also fun and easy for people to use. Dive in, try things out, and see how your web projects can shine!...

A Deep Dive into SvelteKit Routing with Our Starter.dev GitHub Showcase Example

Introduction SvelteKit is an excellent framework for building web applications of all sizes, with a beautiful development experience and flexible filesystem-based routing. At the heart of SvelteKit is a filesystem-based router. The routes of your app — i.e. the URL paths that users can access — are defined by the directories in your codebase. In this tutorial, we are going to discuss SvelteKit routing with an awesome SvelteKit GitHub showcase built by This Dot Labs. The showcase is built with the SvelteKit starter kit on starter.dev. We are going to tackle: - Filesystem-based router - +page.svelte - +page.server - +layout.svelte - +layout.server - +error.svelte - Advanced Routing - Rest Parameters - (group) layouts - Matching Below is the current routes folder. Prerequisites You will need a development environment running Node.js; this tutorial was tested on Node.js version 16.18.0, and npm version 8.19.2. Filesystem-based router The src/routes is the root route. You can change src/routes to a different directory by editing the project config. ` Each route directory contains one or more route files, which can be identified by their + prefix. +page.svelte A +page.svelte component defines a page of your app. By default, pages are rendered both on the server (SSR) for the initial request, and in the browser (CSR) for subsequent navigation. In the below example, we see how to render a simple login page component: ` +page.ts Often, a page will need to load some data before it can be rendered. For this, we add a +page.js (or +page.ts, if you're TypeScript-inclined) module that exports a load function. +page.server.ts If your load function can only run on the server— ie, if it needs to fetch data from a database or you need to access private environment variables like API key— then you can rename +page.js to +page.server.js, and change the PageLoad type to PageServerLoad. To pass top user repository data, and user’s gists to the client-rendered page, we do the following: ` The page.svelte gets access to the data by using the data variable which is of type PageServerData. ` +layout.svelte As there are elements that should be visible on every page, such as top-level navigation or a footer. Instead of repeating them in every +page.svelte, we can put them in layouts. The only requirement is that the component includes a for the page content. For example, let's add a nav bar: ` +layout.server.ts Just like +page.server.ts, your +layout.svelte component can get data from a load function in +layout.server.js, and change the type from PageServerLoad type to LayoutServerLoad. ` +error.svelte If an error occurs during load, SvelteKit will render a default error page. You can customize this error page on a per-route basis by adding an +error.svelte file. In the showcase, an error.svelte page has been added for authenticated view in case of an error. ` Advanced Routing Rest Parameters If the number of route segments is unknown, you can use spread operator syntax. This is done to implement Github’s file viewer. ` svelte-kit-scss.starter.dev/thisdot/starter.dev/blob/main/starters/svelte-kit-scss/README.md would result in the following parameters being available to the page: ` (group) layouts By default, the layout hierarchy mirrors the route hierarchy. In some cases, that might not be what you want. In the GitHub showcase, we would like an authenticated user to be able to have access to the navigation bar, error page, and user information. This is done by grouping all the relevant pages which an authenticated user can access. Grouping can also be used to tidy your file tree and ‘group’ similar pages together for easy navigation, and understanding of the project. Matching In the Github showcase, we needed to have a page to show issues and pull requests for a single repo. The route src/routes/(authenticated)/[username]/[repo]/[issues] would match /thisdot/starter.dev-github-showcases/issues or /thisdot/starter.dev-github-showcases/pull-requests but also /thisdot/starter.dev-github-showcases/anything and we don't want that. You can ensure that route parameters are well-formed by adding a matcher— which takes only issues or pull-requests, and returns true if it is valid– to your params directory. ` ` ...and augmenting your routes: ` If the pathname doesn't match, SvelteKit will try to match other routes (using the sort order specified below), before eventually returning a 404. Note: Matchers run both on the server and in the browser. Conclusion In this article, we learned about basic and advanced routing in SvelteKit by using the SvelteKit showcase example. We looked at how to work with SvelteKit's Filesystem-based router, rest parameters, and (group) layouts. If you want to learn more about SvelteKit, please check out the SvelteKit and SCSS starter kit and the SvelteKit and SCSS GitHub showcase. All the code for our showcase project is open source.
