  • lwc

    ⚡️ LWC - A Blazing Fast, Enterprise-Grade Web Components Foundation

    Project mention: | /r/SalesforceDeveloper | 2023-07-11

    Actually I was wondering if lwc oss is still a thing. The website 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?

    Web Components + Virtual DOM: web standards for powerful UIs (by mixpanel)

    Project mention: Web Components Will Outlive Your JavaScript Framework | | 2023-10-25

    Webcomponents will outlive React 13, mostly likely. Will they outlive React entirely or its cousins like Solid and Svelte? Perhaps not.

    Webcomponents and React look like they solve the same problem but they do not.

    Webcomponent api is pretty shallow. You get connected/disconnnected/attributeChanged call back but gotta write your own property setter and getters, and that’s mostly it. Shadow dom becomes a pain to work with if something needs to pierce it. Can’t pass nested objects in attributes, gotta encode as string.

    Mixpanel went all in on webcomponents, but had to build a whole bunch of lib tooling around it. They made their own framework on top of webcomponents.

    Worked on panel lib and webcomponent UI for many years. It is not a silver bullet.

    The issue with webcomponents is there are a ton of libraries that fill in the missing gaps. There’s not a lot you can do with pure vanilla webcomponent api since browsers don’t provide efficient dom updating mechanism. Google has their own thing, Microsoft had multiple internal libs across orgs, Reddit does their own thing.

    The most standard thing for frontend with wide adoption right now is React.

    So the way I see it, is that React has already outlived webcomponents.
