I feel like this article aids and confuses rather than disputes the current trend of treating React as its own component entity rather than as one implementation of web components. It even says so in the React documentation. , Very nice read but its time to update your article (browser support caniuse.com/?search=web%20components)! Not a lot of other pre-built options though. Polyfills exist for browsers that don't support the spec. 2012.

Many wc helper libraries like lit-element also provide convenience mechanisms to do this in just the same way you would in react. Web Components are easy to write. Just wondering if safe to bring to my platform production code. JavaScript frameworks will continue to be good at what they do best: state management, providing architectural patterns and convenient tooling. I’m listing it here since it’s a useful way to update on new web components from the Polymer team and provides some useful resources to read when starting with web components.

The only thing I'm not sure about is whether Safari already supports customElements.upgrade used in that polyfill: github.com/ungap/custom-elements-b... that polyfill is basically for Safari/WebKit only, so yes, it works there pretty well . There are many quirks to getting web components to work with JavaScript frameworks. If we are comparing Web Components to React, is there a create-react-app comparison? Compare npm package download statistics over time: chart.js vs flask vs material components web react vs react select vs react virtualized vs recharts . I find this very interesting as someone who codes a lot of build tooling when something doesn't exist. I guess I’m just holding out till things stabilize a bit. It's fast. can chime in?

In this episode I talk React / Preact, JSX, all that good stuff... and how it all works with Web Components! Thanks, but are we supposed to ignore Safari development team arguments then as not having much basis? -It is a set of different technologies that allow us to create reusable and isolated elements. We should all be working together to ensure web components make their way into development workflows. Props contain the data passed from the parent component. You always want to create beautiful, engaging, and user-friendly components. Apple has refused to implement the customized built-in elements spec in Safari. We all just need to work together a little better and Web Components can provide a sustainable paradigm for implementing UI components heading into the 2020s. Resources.

The JavaScript ecosystem is so fragmented. I was looking around this past weekend for something that supported at least the following: TypeScript, Webpack, and Hot Module Reloading to make an app using Custom Elements. LogRocket is like a DVR for web apps, recording literally everything that happens on your React app. It is created and maintained by Google. Instead of guessing why problems happen, you can aggregate and report on what state your application was in when an issue occurred. We’ve written at length about the role of the React 17 release and the changes it contains in the React 17 RC blog post. Micro Apps With Web Components Using Angular Elements.

React allows us to create websites that are completely accessible. We're a place where coders share, stay up-to-date and grow their careers. None the less a starter project would be a decent idea or a CLI with scaffolding all the better. The JavaScript ecosystem is so fragmented. For example, with the @ungap/custom-elements-builtin you cannot use class constructors or create new elements with the new operator. It uses the browser’s JavaScript API customElements.define() method to do that. For example, we can use the aria-* attributes in JSX in the same way we use them in plain HTML, i.e., they do not need to be camelCased. React Native geolocation: A complete tutorial, Microsoft’s Fluid Framework: An introduction.
