  • A love letter to Apache Echarts
    6 projects | news.ycombinator.com | 18 Feb 2024
    If you are generally interested in how to write components that can be used by many frontend libraries (react/vue, etc), you should take a look at https://github.com/microsoft/fast. I was tangentially involved with porting an existing component library to it and the end result was pretty framework agnostic and well made.
  • Microsoft's Adaptive UI

    Could not have articulated it better, especially when compared to other MS project sites like https://www.fast.design/. Maybe the dev or someone on the team downvoted me :/
  • Making Web Component properties behave closer to the platform
    9 projects | dev.to | 21 Jan 2024
    I know FAST is not used that much but I wanted to cover it as it seems to be the only library that reflects attributes by default. By default it won't do any type coercion unless you use the mode: "boolean", which works almost like an HTML boolean attribute, except an attribute present but with the value "false" will coerce to a property value of false!
  • Shadow DOM: Not by Default
    5 projects | dev.to | 18 Aug 2023
    This doesn't mean you are required to write vanilla JavaScript web components either. If you are familiar with using Fast or Lit to write web components you can include those libraries in you Enhance application. However, with the introduction of Enhance base classes for the light and shadow DOM you can get the same DX improvements where you write less boilerplate web component code while enabling the sharing of a render method between the SSR and CSR rendering.

  • Writing JavaScript without a build system
    13 projects | news.ycombinator.com | 16 Feb 2023
    I just want to point out there is a great alternative from Microsoft called `fast-design`[0] which provides a more fleshed out experience than Lit does, in terms of out of the box components.

    It does have lower level packages if you don't want ready made components too

  • As a .NET developer, what's your preferred front-end?
    2 projects | /r/dotnet | 19 Jan 2023
    Rob Eisenberg is also one of the brains behind the FAST web component library, which is also pretty nice. Sadly he seems to build awesome things that don't gain a lot of traction.
  • How often is JS inheritance used in your workflow ?
    2 projects | /r/node | 9 Nov 2022
    The web component-based frontend framework FAST, for example, uses inheritance. UI widgets extend a base FASTElement, which in turn extends HTMLElement. This framework powers webpage-like portions of your OS.
  • What blazor wasm componet do you need today?
    4 projects | /r/Blazor | 17 Oct 2022
    Just want to throw my 2 cents in here: Use platform agnostic solutions for most smaller and even some larger components. A great way to create components that can be used anywhere is Microsoft FAST.

  • lwc.dev
    2 projects | /r/SalesforceDeveloper | 11 Jul 2023
    Actually I was wondering if lwc oss is still a thing. The website lwc.dev looks like it hasn't been updated since the release in 2019. Are many people using it or was it a nice try by Salesforce but can we consider it dead? I know of course it can't compete with react, vue or angular, but has it built a nice user base around it to keep it interesting?
    2 projects | /r/SalesforceDeveloper | 11 Jul 2023
    I have been a Salesforce Apex/VF developer for over 8 years now and I would like to make a standalone web app (spa/pwa) in some javascript framework and make use of Salesforce api's on the backend. I know that lwc.dev exists, but I wonder if this is still worth the effort to have a look into or can I better go with one of the more popular frameworks like vue or react?
  • The benefits of Web Component Libraries
    4 projects | dev.to | 27 Feb 2023
    Web component browser APIs aren't that many, and not that hard to grasp (if you don't know about them, have a look at Google's Learn HTML section and MDN's Web Components guide); but creating a web component actually requires taking care of many small things. This is where web component libraries come in very handy, freeing us of having to think about some of those things by taking care of them for us. Most of the things I'll mention here are handled one way of another by other libraries (GitHub's Catalyst, Haunted, Hybrids, Salesforce's LWC, Slim.JS, Ionic's Stencil) but I'll focus on Google's Lit and Microsoft's FAST here as they probably are the most used web component libraries out there (ok, I lied, Lit definitely is, FAST not that much, far behind Lit and Stencil; but Lit and FAST have many things in common, starting with the fact that they are just native web components, contrary to Stencil that compiles to a web component). Both Lit and FAST leverage TypeScript decorators to simplify the code even further so I'll use that in examples, even though they can also be used in pure JS (decorators are coming to JS soon BTW). I'll also leave the most apparent yet most complex aspect for the end.
  • The Journey to Becoming a Rockstar Salesforce Developer
    2 projects | dev.to | 12 Jan 2023
    Now in Alba’s role, she and her team use Lightning Web Components (LWC) to create custom user interfaces, a framework based on Web Components standards. With LWC, Alba creates components using modern, standard JavaScript. This means the skills that she learned previously are transferable to other JavaScript-based technologies. She pointed out that on top of this transferability, LWC is open source, and developers can use it outside of the Salesforce platform. Components can be used in Lightning App Builder and published on the AppExchange for other customers to use them.

    Indeed. Ever built anything in LWR+LWC opensource? It's opensource where you don't get to open its source. Most of the documentation is a mess between outdated Aura components and their new lwc.dev site which has like 2% of the material you actually need.

    Salesforce developed Lightning Web Components (LWC) as a fast, enterprise-grade wrapper around vanilla web components. LWC is built on the same HTML, CSS, and JavaScript that powers the web, so any analyzer for those languages can be applied here.
