ReactJS is a powerful JavaScript library to create user interfaces.

  • Preact vs React: A Comparative Guide
    In this post, we get to know more about Preact, one of this year's trending libraries. And we'll compare it to React to see which one suits better for our projects. - Source: dev.to / 29 days ago
  • Episode 24/13: Native Signals, Details on Angular/Wiz, Alan Agius on the Angular CLI
    Similarly to Promises/A+, this effort focuses on aligning the JavaScript ecosystem. If this alignment is successful, then a standard could emerge, based on that experience. Several framework authors are collaborating here on a common model which could back their reactivity core. The current draft is based on design input from the authors/maintainers of Angular, Bubble, Ember, FAST, MobX, Preact, Qwik, RxJS, Solid,... - Source: dev.to / about 2 months ago
  • How I built a cross-framework frontend library
    At the very bottom of the image, there are 3 blocks that I chose to call application components. If you are building a cross-framework library, these can be built with whatever tools you want! Only catch is, all the tools you use to build it, will be needed by everyone consuming it. So choose wisely, and be mindful of how many kilobytes of third party code you will need in order to ship. In Schedule-X, I chose to... - Source: dev.to / 5 months ago

  • HTML Data Attributes: One of the Original State Management Libraries
    DEV is a Rails monolith, which uses Preact in the front-end using islands architecture. The reason why I mention all this is that it's not a full-stack JavaScript application, and there is no state management library like Redux or Zustand in use. The data store, for the most part on the front end, is all data attributes. - Source: dev.to / 6 months ago

  • KILLSWITCH
    So my first instinct is to setup some sorta feature-flag thing within a CMS so managers can flip the boolean, I'm exploring getunleash.io and GrowthBook.io and we already use Contentful.com within the app but they're saying they "really don't think we need to use any third party thing for a killswitch"...

  • How we use analytics as a privacy focused OSS company
    TLDR: Privacy is really important for us at Unleash. Here you will find the full story on how we ended up with an analytics solution that does not collect personal data and has very short retention.

It can quickly qualify or disqualify a feature from consideration, putting... - Source: dev.to / almost 2 years ago
