  • How I Redesigned My Website With SvelteKit | 2021-10-07
    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) | 2021-09-22
    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 | 2021-09-03
    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? | 2021-07-09
    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? | 2021-05-28
    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 | 2021-05-23
    I am not sure whether or not they help you, but both and are open source. both of those projects are built on sapper, not svelte-kit, but a quick look at 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 | 2021-04-11
    SSR (Server Side Rendering): the process of receiving a request from the client, e.g: a user goes to 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](, [NuxtJS](, [Angular Universal](, [SvelteKit]( (currently in Beta) and [Sapper]( (currently going deprecated);
  • Getting my SvelteKit website on Netlify | 2021-04-10
    But wait a minute? The local version is not working anymore? Apparently, Vite, the local build tool, did not like it when I moved the packages. After trying several things, I gave up. As SvelteKit is still in beta, community resources are scarce. I did found a few Sapper examples, the predecessor of SvelteKit, using the adapter-static. Success! Well... kind of.

  • Go for web frontend | 2021-10-19
    Currently I'm exploring turbo + stimulusjs ( which I find very easy to use and it can bring modern touch to the old school server side rendering. Which is something I prefer.
  • Infinite Scroll with HOTWire Part 1: Configuration | 2021-10-17
    HOTWire is a new set of tools extracted from Hey by Basecamp. It uses Asynchronous HTML and HTTP (also known as AHAH) to render partial updates to the DOM without a full browser reload. You build your servers with any language of your choice and let Turbo handle the partial updates for you. Which makes your application to have a speed of an SPA while having the benefits of server-rendered partials. | 2021-10-17

  • Ask HN: Is there a CDN that pre-renders the app on the server? | 2021-10-11
    I think basecamp is working on this kind of technology, but I think it is somewhat common for some performance focused shops to pre-render their initial HTML and cache it in their load balancer.

    Basecamp I think is taking it a step further.. read more here:

  • Ask HN: Why aren’t frameworks like htmx more popular? | 2021-10-10
    Rails, one of the most popular web frameworks, comes with .

    I count this as very popular.

    While the tendency to over engineer web apps is strong, many teams opt for faster development.

  • Hotwire in Laravel app? | 2021-10-07
    Have any of you guys used the Hotwire stack ( in your laravel apps? How was your experience?
  • Reactive Clojure: You don't need a web framework, you need a web language | 2021-09-23
    I think Phoenix LiveView (posted recently on HN: and Rails Hotwire ( are the main alternatives that have momentum right now.

    The general idea being to abstract away the difference between client and server code, so that you can write code that handles both, in a single file.

    > There has got to be a better way

    What's offensive about the OP to you? Is it just that you don't like functional programming / Clojure (fair, that's ultimately a matter of taste / aesthetics at some level)? Or is there something about the technical implementation you think is suboptimal?
