It will be better implemented wiht ES6 proxies. ), Would work with a Flux implementation like Redux, It doesn't "feel" ready yet, a lot to cobble together, If we implement today and the Web Component standard changes, we're in the same boat as we were with React/Angular/Whatever. Typical example when you want to create a vanilla DatePicker with its own logic and you want to hide its implementation detail. We’ll talk more about how it works below. React has two different approaches to dealing with form inputs. They at least give you a standardized and declarative way to instantiate components. It's there. It probably has reasons and solutions, but it's unnecessarily complicated for me and my team. React allows you to pretty much script everything directly. They have a home-grown framework built with Backbone/Marionette. Meanwhile, today there are a lot of people who write HTML in Haml or Jade, CSS in Sass or Less and JavaScript in CoffeeScript or TypeScript. HTML Imports, you don't actually need. Why do you think Angular2 is copying a lot of ideas from React? Why I think Web Components (specifically Polymer) could be a good approach, Follows a standard that is meant to be implemented in all browsers, React components would have to be re-written (again) if we wanted to use the Next Big Thing on another part of the site, Eventually we wouldn't need a library (like polymer) for our components, These components can be used in any React/Angular/Whatever (future) project, React components have a hard dependency on React, it would be weird to use them in an Angular project (or maybe it wouldn't be? There are some things about Web Components/Polymer that React devs assume (including myself) that might not be fair: Too much is up in the air and breaking changes are likely to occur. React Virtual DOM. We would adapt components from Material UI to suit our needs rather than re-writing from scratch. I’m using just React, but I think it will be possible to use both at the same time. @fluentui/web-components. Can you use web components today in production? In an ideal world, you would spend a little time building something basic with each, and compare your experiences. ;-), Regarding React, I really really like the way it manages state. Many other sites do too. The best part of this article is the idea that Angular is HTML-centric whereas React is JavaScript-centric. Maybe React is widely used but there is so weird stuff going on with mixing JS, HTML and preventing the open web heavily (I hope for the sake of internet that it will die out soon). These tools help to maintain and reuse code. a date picker, a colour picker, pane splitter, a SVG canvas or viewer. You can also render a React tree into a shadow DOM (though I am not sure if React’s reconciler will work or not): I prefer React and that's what we are using right now without any regret. React uses a concept known as Virtual DOM (VDOM), where a virtual representation of the UI is kept in memory and synced with the real DOM through a process called reconciliation.The reconciliation process will find the difference (diffing) between the Virtual DOM (An object in memory, where we push the latest updates to the UI) and the real DOM (DOM holding the … I was kind of in the same situation debating React vs. Polymer, and some others in the project leaned more towards Polymer. Maybe she/he has missed something that I can watch out for if I go Polymer? They also have a library of custom components they've created using this framework which will need to be rewritten. To get a little more specific to React, here’s a couple of React imports. React will happily operate on HTML elements and also web components (because they look and act like HTML elements, that is the whole point of web components). Data-binding in Polymer is a nightmare if you aren't/can't use it exactly the way they want you to. 13. They want to find a path off this framework and on to something more "industry standard." I am not experienced enough with React or Web Components to have a valid opinion but I just wanted to add that https://gaming.youtube.com/ is build with Polymer (Web Components). React Native is the undisputed king of cross-platform development. I say this even as I am developing an alternative that I think is better in some ways. Web Components is something we should at least evaluate seriously. There are a lot of components in the Paper and Iron sets, but unless they do exactly what you want them to do, you're probably going to have to write out every component you want to use, which negates the whole point of using Polymer in the first place. Speak openly about the pain points to both approaches and inform your decision by actually writing code in each approach. Or just keep using React even when it's no longer the cool new thing. I think the developers said so themselves, they were taking a lot of hints from react and improving on them. Also, code can be synced across projects. What does it get right? This React thing is so hot right now, but might not be in 1-2 years. New comments cannot be posted and votes cannot be cast. You can use web components … And what assumptions have I wrongly made? I've been writing react for a little over a year, but have also kept my eyes on mobile development. The biggest ones I know are shadow DOM and piercing selectors, but those seem to be solidifying. It takes props, manages the state of a component, and returns the JSX code through the render function. And you see this even looking at the rapidly evolving history of JS projects. The APIs are reaching the final v1 stage. It requires you to extend from React. Use snippet libraries The JavaScript ecosystem is so fragmented. r/reactjs: A community for learning and developing web applications using React by Facebook. still suffer from, Model updates (sync and async) beget UI updates gracefully, Huge community, lots of examples to learn from, Big players (Facebook, Reddit, BBC, Netflix) using it and learning from it in production today. Anything React or whatever can do regarding optimisations etc, a web component can do to. These design decisions can still be re-used elsewhere. Beyond that, it helps code to become discoverable, and promotes team collaboration in building components. Web components are not fully baked right now, and I believe that they've fundamentally solved one problem by creating a bunch of new ones. SuspenseList helps coordinate many components that can suspend by orchestrating the order in which these components are revealed to the user.. So use Web Components to create custom HTML elements (like custom controls in WinForms, WPF etc.) React is the way to go right now. still suffer from, Model updates (sync and async) beget UI updates gracefully, Huge community, lots of examples to learn from, Big players (Facebook, Reddit, BBC, Netflix) using it and learning from it in production today. You can count on us in the long run. pages of inputs etc which you often see in your typical CRUD app. There is a great presentation on YouTube (https://www.youtube.com/watch?v=g0TD0efcwVg) I really recommend it to make the right decision. 注意: Web Components 通常暴露的是命令式 API。例如,Web Components 的组件 video 可能会公开 play() 和 pause() 方法。 要访问 Web Components 的命令式 API,你需要使用 ref 直接与 DOM 节点进行交互。 如果你使用的是第三方 Web Components,那么最好的解决方案是编写 React 组件包装该 Web Components。 Web components are mostly an idea at the moment, I don't know anyone using them at anywhere near the same scale. https://www.youtube.com/watch?v=1tavDv5hXpo. React VR marked the first efforts of Facebook to allow the creation of VR experience right in the web browser. I have proposed a React/Flux solution as the path off the old framework. Web Components officially covers four main technologies — Custom Elements, Shadow DOM, HTML Templates, HTML Imports — but the critical ones that most people use are Custom Elements and Shadow DOM. Even before that people refused to trust assemblers and preferred to write native machine code by hand (and I'm not joking). It provides over 50 customizable components that can be used to craft beautiful applications. And you too can use it to create fast and feature-rich apps with impressive UI. The reason for this is because, in create-react-app, a React component will have an accompanying file to hold its styles, whereas Vue CLI adopts … Node JS vs. React JS Comparison. Either way you need to be prepared to update your code when the APIs and Chrome implementation changes. (Shadow DOM is one IIRC, and Custom elements are getting there and being worked on. What does it get right? I've been working on a project using Polymer the last few months. Back in the day there were hot debates whether one should write native Assembly by hand or use a higher level language like C to make the compiler generate Assembly code for you. However - IMO, the biggest downside in comparison to React is that you can only declaratively pass string and boolean data into a Web Component (though, to be fair - you can build a lot of components with just that). Web components … This is more or less my feeling. I've also done a lot of work with web components in Chrome (Electron namely). :-) ) All of the browser makers are now busy implementing support. If you want to use the web components APIs directly today then no unless you are only aiming at Chrome support. In practice, however, I tend to think React would be a wiser investment. Even if React components only work with React, the majority of the effort you spend is not on React-specific implementation, but on separating your functionality out into single-concern components. Instead of using BEM (.YourCustomElementのsubElement) or CSS modules, you can use shadow DOM selectors (your-custom-element::shadow .sub-element). You can create 100% native widgets that control their own style. Even styling is kind of a pain. Ant Design is a set of enterprise-class UI designed for web applications. When multiple components need to fetch data, this data may arrive in an unpredictable order. @fluentui/web-components makes use of different stylesheets and may include components that specifically support Microsoft's Fluent design language. As a developer, you are free to use React in your Web Components, or to use Web Components in React, or … 13. Web Components is something we should at least evaluate seriously. In this 57-part interactive tutorial, you'll learn how to build dynamic, interactive web applications with React.js in 2019. @fluentui/web-components is a library of Web Components that composes @microsoft/fast-foundation. There's always going to be something around the corner that you might want to hold out for, but in practice, going with what works at the moment and switching to something new only after it actually becomes available has far better results. by doing it on the go whenever you touch one of them), and remove React once you've converted all of them. Round 10: Mobile. Prior art around testing. A larger ecosystem of open source code. You can build your own design system, or start with Material Design. And in my view at least, what comes after React will discard things like direct access to native DOM elements, refs, and baked in local state handling in favor of a more principled, functional approach, and you may or may not see things like signals and observables making an appearance. 2. Below, we compare React with Node js, their pros, cons, and usage so you can compare them for your proposed project. The component set is built specifically for React development. It boasts an impressive client list that includes Microsoft, NASA and Sony. Also, moving to Web Components later should be relatively easy. They also have some very serious limitations: they must be stateless, and they must be minimal. This post is a brief summary of it, so if you’ve already read the RC post, you can skip this one. All about the JavaScript programming language! Perhaps Web Components will evolve a bit more and we'll see the two merge into one, eventually. Did React fix the main problem you had with Angular and Polymer, i.e. I believe once Web Components land and people start building and sharing them, they will end up being minuscule elements that are better off being implemented natively in whatever framework you are using to build your app, such as React. In less abstract terms, stuff your old home-grown components into a web component if you want to reuse them. API stability. Web components is a nice concept that finally getting some attention and hopefully could change the framework mess we have today. I think you know this deep down, or you would have posted the same question over in r/polymerjs. If you’re curious, you can find their d… What features are you concede about being up in the air? //imrc import React, { Component } from 'react' JavaScript Iteration. React VR marked the first efforts of Facebook to allow the creation of VR experience right in the web browser. It provides a lot of React components for faster and easier web development. Suspense lets your components “wait” for something before they can render. Press J to jump to the feed. Today, we are releasing React 17! Will it be drastically different? React is a fantastic front-end library for building user interfaces. React kept that and threw out all the crazy data binding and scope watching stuff for something simpler and better. You shouldn't, for example, use React inside a Web Component. In fact, we're worse off because we're using an obscure and deprecated component approach. @fluentui/web-components makes use of different stylesheets and may include components that specifically support Microsoft's Fluent design language. I don't think it's a concept that can ever be very useful. As a RN beginner, I'm trying to get into the react-native community and make a … It's an approach that I'll be using myself in the future even outside of React. If you want to learn more about React, check out the docs here. I echo the experience that Neocronic had. @fluentui/web-components is a library of Web Components that composes @microsoft/fast-foundation. I admit I have a bias toward React mostly because I've used it in the real world. Why I think Web Components (specifically Polymer) could be a good approach, Follows a standard that is meant to be implemented in all browsers, React components would have to be re-written (again) if we wanted to use the Next Big Thing on another part of the site, Eventually we wouldn't need a library (like polymer) for our components, These components can be used in any React/Angular/Whatever (future) project, React components have a hard dependency on React, it would be weird to use them in an Angular project (or maybe it wouldn't be? Ant Design. You can probably see which way I lean here. There's nothing wrong with that either, if something works there's no shame in reusing it .. especially in open source. The component set is built specifically for React development. Feel free to use React or Vuejs or whatever to push your components around. We keep the good ideas and throw out the rest. And you too can use it to create fast and feature-rich apps with impressive UI. //imrc import React, { Component } from 'react' JavaScript Iteration. Import React //imr import React from 'react' Import React and Component. You can create a class by defining a class that extends Component and has a render function. Not yet, at least. React components. They want to use these components company-wide in the future. If you have a strong need/desire to build components which can be shared across different frameworks - Web Components are probably worth looking in to. Thats something web components will likely never solve for. The reason for this is because, in create-react-app, a React component will have an accompanying file to hold its styles, whereas Vue CLI adopts … ReactJS is a much cleaner model overall, especially if you pair it with a global state (see Redux or clojure's Om). Keep in mind that Suspense is more of a mechanism, and particular APIs like fetchProfileData() or resource.posts.read() in the above example are not very important. ), Would work with a Flux implementation like Redux, It doesn't "feel" ready yet, a lot to cobble together, If we implement today and the Web Component standard changes, we're in the same boat as we were with React/Angular/Whatever. If you want to learn more about React, check out the docs here. I'd go for React with JSX. You can use web components inside of react. To demonstrate Web Components in React, we will use the Create React App CLI tool to easily create a React application. No, but maybe yes. The focus of this question is around the components. It is the best framework to use if you want to create a Material Design app easily. Web Components are an opportunity for everyone to speak the same language. Press J to jump to the feed. @fluentui/web-components. I am curious to know why you believe this. I think there are still major improvements to be made over what React offers, and things like Cycle.js, Elm, and my own little project, vdux/virtex may have some things to offer, but they are all going to use a purely rendered UI tree over some virtual-dom or virtual-dom-like abstraction. Fundamentally, managing complexity in UI applications is about managing state, and React recognizes this and embraces it. If this isn't your first app clone, this is a great chance to move beyond the web and build a mobile app with React Native. They also have some very serious limitations: they must be stateless, and they must be minimal. Might as well just do it in React, which is far more capable. I got some good feedback from React devs and crickets from polymerjs devs. React VR vs React 360. What a succinct description. It boasts an impressive client list that includes Microsoft, NASA and Sony. While Web Components may be good in theory, pragmatism is generally the best policy when you're not an artist. React is a JavaScript library for creating user interfaces. You could look at what Amazon is doing internally with web components, they created a meta-component format since pure web component wasn't mature enough for them. You are free to use Web Components within React components and vis-versa, so I don't think using React locks you out from moving to Web Components later. Go with what works today, and you won't have a headache. Preact, by the way, largely mitigates those caveats. Give both technologies a spin, but timebox your experiences and make sure several developers try out each one - not just each platform's respective advocates. You can build your own design system, or start with Material Design. And this is where Web Components fit into this picture. Ant Design is a set of enterprise-class UI designed for web applications. Unfortunately, I think Web Components are fundamentally flawed, on a conceptual basis. The poin… TL;DR; Web Components are awesome, and Polymer is a nice library, but not quite there yet for advanced single-page applications, and assuming you want to use ONLY material design. React is well proven and currently used by A LOT of major players, web components isn't really even out of beta yet. I personally think the idea of web components is amazing, and Polymer does a good job at allowing you to make self-contained components that you can just place anywhere, but I don't think it's quite there yet for more advanced applications. I hit this problem when trying to use React deep inside a web component of mine which uses the Shadow DOM. and use React to create components (set of HTML elements). Maybe use React+Flux for view rendering (handling data flows) and use Web Components for encapsulating UI, styles (shadow DOM, etc), and interactivity. (Beware that React doesn't like being placing inside a Shadow DOM, and the React team appear to have become so hostile to web components that they are not even interested in supporting PRs which fix this problem. More Than a React Component Library. Proponents of React are quick to point out there is "no single 'web component community', but the truth is the community is all of us. There are two steps to creating an HTML custom element: 1. Ant Design. I don't think it needs merging. This is a question that I've spent quite a lot of time researching and discussing with coworkers. It provides a lot of React components for faster and easier web development. This DatePicker will be considered as a native HTML element (or I would say it would be looked like a
or
etc.) the "namespacing" issue? For each iteration We've been solving this problem for the past 18 years across many development platforms, which now include four JavaScript frameworks. Similarly, whatever comes after React will almost certainly keep the pure component tree, explicit management of state, and the DOM <-> component mapping brought in from Angular. You know what it offers. I don't have an answer for you, but here are some points to consider: Just because something is on the standards track doesn't mean it is standardised. Though maybe things are converging a bit? The majority of messaging apps are on mobile devices or tablets. Fundamentally, Web Components were not built for your problem, to break up an application into separate document fragments with their own viewmodels and templates. The simplest way to define a component is to write a JavaScript function:This function is a valid React component because it accepts a single “props” (which stands for properties) object argument with data and returns a React element. If you could build a small widget that was complicated enough to require lots of nesting, a bit of state and decent test coverage, this would let you bottom out the problems to each approach (particularly the question about testability - that should actually be one of the most important of all). I've also done a bit of React, not a lot, but enough to get a good feel for what it brings to the table. Take a look at this comparison of React vs Angular vs Vue.js according to the Google trends. For example, Object.observe was supposed to be in ES6, then it was supposed to be in ES7, and now who knows when it'll actually be a "standard". React uses a concept known as Virtual DOM (VDOM), where a virtual representation of the UI is kept in memory and synced with the real DOM through a process called reconciliation.The reconciliation process will find the difference (diffing) between the Virtual DOM (An object in memory, where we push the latest updates to the UI) and the real DOM (DOM holding the … I saw a comment elsewhere (I think HN) mentioning that it might actually make sense to eventually have a React-like standard at some point in the future. The critical vision behind Web Components is to provide a safe environment to create components without turning your page into a mess — encapsulation, and isolation — . You would quite literally start your project with technical debt. 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. React, on the other hand, needs third-party libraries like Next.js to render pages on the server. Using the DOM tree to specify your UI components was an angular thing and that was a good idea. A mirror API for writing native browser apps. ;). There are some minor caveats surrounding custom events, due to the odd way that react works with the DOM, but there's a well-trodden cowpath for working around react's eccentricities on that front. Write a class that extends HTMLElement (or any of its derived type, such as HTMLParagraphElement). Both React.js and Node.js are different technologies used to develop different parts of a web app. Tooling isn't bad, but it isn't great (polymer specific), No good examples for testing ([here] is Google's example which is disappointingly half-baked), Some things seem shaky still like component lifecycle initialization order, Google pulled the rug out from under us and deprecated 0.5 when the released 1.0, Why I think React with Flux is a better approach, It's ready and being used, there are lots of resources and examples to draw from, Stateless React components render deterministically, This solves a large class of UI rendering issues that Web Components would (presumably?) For example, let’s create one called ‘MyButton’: Now that we have shell, let’s make it so this component will render a React button component when applied to the page. React, on the other hand, was built for your exact use case. And have a contingency plan to turn backwards if you discover you've made the wrong choice. You can keep using React while you're converting your old components (e.g. This React thing is so hot right now, but might not be in 1-2 years.
