  • How to update values in database shown in html table?
    3 projects | | 24 Nov 2021
    This is a bit complex, and you might want to use a UI framework like React, Vue, or Svelte.
  • I built svelte-link-preview

    When linking 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 | | 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 | | 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 | | 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 | | 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".

  • Are there any nice Svelte datagrid components?
    1 project | | 15 Nov 2021
    Agree. However I haven't been able to overcome slight lag when custom cells are rendered. I'm using svelte components which is not ideal since svelte carries a lot of extra code and it's esp noticeable with very small components. Wonder how templates pr might improve this (
  • Would you use Sveltekit for production?
    1 project | | 13 Nov 2021
    I’ve been using it in production for months now, and started the project the day SvelteKit went public, have had absolutely no issues. As for tutorials, honestly the docs have been enough with how straight forwards they are. Sometimes if I didn’t fully understand a concept I’d look at the RealWorld SvelteKit implementation. Another good thing to look at is the sites repo. You mentioned connecting to a database and not being able to find tutorials for it, so there’s how the Svelte site does it. Imo the best tutorial is production-code written by the people who made the thing you’re using.
