  • Build your own component library with Svelte

    SvelteKit can be considered the successor to Sapper or NextJS for Svelte. It is packed with tons of cool features, like server side rendering, routing, and code splitting.
  • How I Redesigned My Website With SvelteKit
    3 projects | dev.to | 7 Oct 2021
    So after using Sapper for some time, I decided to move my website to SvelteKit. I remember saying that I would not move to SvelteKit till they hit version 1 but the framework looks too promising. It had features which I needed and those features weren't in Sapper.
  • Journey to Svelte (through Gatsby)
    5 projects | dev.to | 22 Sep 2021
    By that time, we had some troubles with virtual dom itself in our custom rich text editor that we based on slate - it was getting a bit laggy when creating huge financial documents (they usually have enormous tables and a lot of infographics) -so we were already thinking about other options and that’s where svelte comes into the light - especially sapper which was de facto default framework to be used with svelte at that time (SvelteKit wasn’t even announced).
  • Deploying Sapper application to Deta.sh

    Sapper is a framework for building web applications of all sizes, with a beautiful development experience and flexible filesystem-based routing. It is the predecessor of Sveltekit.

  • Sveltekit - to use or not to use?
    6 projects | reddit.com/r/sveltejs | 9 Jul 2021
    I maintain a Svelte Starter Kit and all I had to do between several updates is change the layout file names, simplify the hooks, and convert the config file extensions. If you're learning Svelte in 2021, you shouldn't miss learning it, as it's "the missing CLI" and the svelte team's favoured project structure, to build full-stack server rendered and static sites, with File/Folder based routing, focus on server-less with adapters, API routes, and good baked-in conventions and constructs to support common web app needs. It's a successor to Sapper which served the aforementioned needs, with exception of adapters, which is special/unique(with no officially provided parallels in Next.js/Nuxt ecosystems yet) way to make vendor-agnostic, server-less first deployment concern a seamlessly integrated part of the framework.
  • Javascript's import vs require?
    1 project | dev.to | 28 May 2021
    Since Node v12, ES modules has been enabled by default. Hence my use of '.mjs' to run my file including a node module. Another way to resolve this issue is to use import with Node.js, you have to edit the package.json to 'type':'module'. However, using this caused my Sapper server to crash since it wasn't supported, as the rollup file outputs the format to commonjs Explained in (this GitHub issue).
  • planning to learn svelte for front-end, need advice
    6 projects | reddit.com/r/sveltejs | 23 May 2021
    I am not sure whether or not they help you, but both svelte.dev and sapper.svelte.dev are open source. both of those projects are built on sapper, not svelte-kit, but a quick look at kit.svelte.dev/migrating should be enough to see what changed. (both of those make heavy use of markdown files so I don't know how helpful they are, also if you need help translating something from sapper to svelte-kit just reply and I'll probably be able to help)
  • Difference between SSR, SSG, CSR and SPA
    10 projects | reddit.com/r/nextjs | 11 Apr 2021
    SSR (Server Side Rendering): the process of receiving a request from the client, e.g: a user goes to https://example.com to load the homepage, and returning a rendered version of the webpage with all the needed info and data to load it as fast as possible. Examples of this are [NextJS](https://nextjs.org), [NuxtJS](https://nuxtjs.org/), [Angular Universal](https://angular.io/guide/universal), [SvelteKit](https://kit.svelte.dev/) (currently in Beta) and [Sapper](https://sapper.svelte.dev/) (currently going deprecated);

    Her name is Svelte (slender and elegant). But the name was inspired from a software framework called Svelte
  • Svelte's lifecycle methods can be used anywhere
    3 projects | dev.to | 30 Nov 2021
    I haven't quite wrapped my mind around it, but you can even use afterUpdate in Svelte to replicate React's useEffect hook. See this example from Rich Harris, which I found in an interesting GitHub issue discussing the edges of Svelte's reactivity.

    This is a bit complex, and you might want to use a UI framework like React, Vue, or Svelte.

    When linking https://svelte.dev/ the description is set to null which is probably due to the uppercase letter in the meta tag? Is this something the proxy could/should take into account so the description is read nevertheless?
  • The Sacred Steps to Achieving Good Documentation
    5 projects | dev.to | 23 Nov 2021
    Of course, the correct tool, as usual, depends on the requirements of your project. For an API, Apiary might be your best choice, if you want a more generalized documentation you Read the Docs might give you a quick and free way to have your documentation up and running, however if you really want a lot more control over styling and such, docussaurus can really help. There is also a last option which is quite rare though: just make a static website from the ground up. You can use React, Svelte, or really anything you want to build a documentation site. It's a lot more work than any of the previous options, but if you truly believe you need to control every single aspect  of your documentation it is still a possibility.
  • Adding React to an Optimizely UI - Part 2
    7 projects | dev.to | 19 Nov 2021
    But the big name players are still React, Angular and Vue, in my opinion (and I fully confess there was a lot of my opinion in the decision phase here!). Other noteworthy candidates were Next.JS and Svelte.
  • Dev in Dev: Issue 1 Nov 2021
    3 projects | dev.to | 18 Nov 2021
    AJAX and Single Page Apps ushered in a new age of web experiences, however it is not without it's flaws. Transitional Apps is a new paradigm of web apps which proposes a new direction. Rich Harris of Svelte introduces this concept at Jam Stack Conf 2021.
  • Testing Svelte components with Jest and Vite
    8 projects | dev.to | 18 Nov 2021
    Svelte hasn't anointed a set of testing tools or does not advocate for a particular testing strategy. It gives some basic advice. More established frameworks have recommendations and integrations specific to their CLI tooling - React recommends using Jest and React Testing Library, and Vue recommends using Mocha or Jest with Vue Testing Library. In theory, you can use whatever JavaScript testing library you want for testing, because in the end you will be testing JavaScript code, regardless of whether it is transpiled or not. However, it can prove to be tricky to integrate different tools into a frontend toolchain for your "dev stack".
