React vs UDash: What are the differences?

What is React? A JavaScript library for building user interfaces. Lots of people use React as the V in MVC. Since React makes no assumptions about the rest of your technology stack, it's easy to try it out on a small feature in an existing project.

What is UDash? Scala and Scala.js Reactive Web Framework. A Scala.js framework for building beautiful and maintainable web applications.

React belongs to "Javascript UI Libraries" category of the tech stack, while UDash can be primarily classified under "Front-End Frameworks".

React and UDash are both open source tools. React with 132K GitHub stars and 24.5K forks on GitHub appears to be more popular than UDash with 348 GitHub stars and 28 GitHub forks.

      For those who want to develop business in China, Vue.js would be your first choice. I never thought Vue.js is better than Angular 2 or React , but for project language choosing, sometimes you should not only consider technology advance, but also must consider human resource market.

      In China, there are far more engineers familiar with Vue.js than React and Angular, that means you can easily hire some front end engineers with much cheaper price. The reason why Vue.js is so popular in China is just because the community, as Vue.js author You Yuxi is Chinese, the community around Vue.js is mainly in Chinese language and most engineers speaks Mandarin, thus they can get questions and problems solved at first time.

      From technical side, Vue.js is more like a simplified Angular, syntax are mostly same, ng-if became v-if, ng-for became v-for. The most convenience part is Vue.js put html+js+css in one single vue file so that you will not have to create a separate folder to include 3 files as Angular does.

      To be frankly, I love Vue.js especially when I need to quickly create a small project contains only 1 or 2 pages even 5 pages, Vue.js would be the best choice, it's small and fast. For a really big and huge project, I will consider Angular, after all, there are far more complicated and interesting plugins to play with, Angular need more time, more code, more complex, but we senior engineer is living for some sophisticated code which only we can understand and set barriers for other beginners, right?

      For developing our #frontend applications, we decided to use Vue.js . Being such an easy to learn library, compared to React for example, it made everything so easy. At first we started with Polymer but the existing tooling and small community at the time made us look for alternatives.

      I use React because I think it is the one that embraces the most the functional component design.

      New versions of React are on the right track.

      Having to work with Vue or Angular is a lot of pain for me, especially because I'm used to the simplicity of React (which comes with the great price of a high learning curve). Also, the use of the Flux Pattern is so much easier with React, being designed as a one way data flow, than with its two foremost competitors.

      Cheers to the React Team, and thank you very much !

      I recommend using Angular 2 when moving from Angular 1 if you are looking for a fully featured framework solution. Neither Vue.js nor React just work out of the box and require creating your own components from scratch as well as the kind of support architecture available in Angular 2 out of the box. However if you are looking for something lightweight to add reusable components to an existing application Vue.js and React are more ideal to that end.

      I use React because it provides a high level of flexibility to architecture the front end app having the posibility or not to incorporate other libraries such as State Management, Routing or Form Validation, among others. Unidirectional flow and component reutilization is another important advantage.

      Back in 2015, my company had a back-office dashboard that was originally built in AngularJS 1. Since Angular 2 presented drastic changes we decided to rethink the options and we looked at React and Vue.js. Besides, at the time, Vue had basically only one developer, its structure (100% oriented to components) and also its backward compatibility focus (Angular 1 to 2 no more) we preferred it against React cause it seemed more straightforward, clean and with a small learning curve. Now 4-5 years later we are very happy with our choice.

      I find using Vue.js to be easier (more concise / less boilerplate) and more intuitive than writing React. However, there are a lot more readily available React components that I can just plug into my projects. I'm debating whether to use Vue.js or React for an upcoming project that I'm going to use to help teach a friend how to build an interactive frontend. Which would you recommend I use?

      I've used both Vue.js and React and I would stick with React. I know that Vue.js seems easier to write and its much faster to pick up however as you mentioned above React has way more ready made components you can just plugin, and the community for React is very big.

      It might be a bit more of a steep learning curve for your friend to learn React over Vue.js but I think in the long run its the better option.

      Having developed in both Vue.js and React, I agree with your assessment of Vue. It does feel light and easier to understand and therefore learn. Seeing that Vue has some genetic roots with React, I would say start your friend out on Vue. If they need to learn React later, that should give them a good foundation. If you have a Pluralsight subscription, look for my course on Vue.js and feel free to use the demo project as a starting point.

      I chose to use Vue.js a few years ago mainly for the easy learning curve. I have no experience with React, so I won't make any comparison here. Regarding available components, I never felt locked in because of Vue when looking for components. It happens that a component I wish to use is not available as a Vue component (and nobody published any Vue wrapper for it), but in such cases I was able to quickly hack a Vue wrapper component. In the end I don't think a decision to choose one framework over another should be made solely because of the number of components available. (And not all components in either framework is maintained, bug free, documented or easy to use)

      React is great, Vue.js is also great. But I'm personally using React, because React is changing the way I look at how JavaScript should be. This is a really big plus for me. Vue is good, but it's just another alternative. Also, too many big companies are using React, that means you can trust it for big projects.

      I picked up an idea to develop and it was no brainer I had to go with React for the frontend. I was faced with challenges when it came to what component framework to use. I had worked extensively with Material-UI but I needed something different that would offer me wider range of well customized components (I became pretty slow at styling). I brought in Evergreen after several sampling and reads online but again, after several prototype development against Evergreen鈥攕ince I was using TypeScript and I had to import custom Type, it felt exhaustive. After I validated Evergreen with the designs of the idea I was developing, I also noticed I might have to do a lot of styling. I later stumbled on Material Kit, the one specifically made for React . It was promising with beautifully crafted components, most of which fits into the designs pages I had on ground.

      A major problem of Material Kit for me is it isn't written in TypeScript and there isn't any plans to support its TypeScript version. I rolled up my sleeve and started converting their components to TypeScript and if you'll ask me, I am still on it.

      In summary, I used the Create React App with TypeScript support and I am spending some time converting Material Kit to TypeScript before I start developing against it. All of these components are going to be hosted on Bit.

      If you feel I am crazy or I have gotten something wrong, I'll be willing to listen to your opinion. Also, if you want to have a share of whatever TypeScript version of Material Kit I end up coming up with, let me know.

      I want to create a video sharing service like Youtube, which users can use to upload and watch videos. I prefer to use Vue.js for front-end. What do you suggest for the back-end? Node.js or Laravel ( PHP ) I need a good performance with high speed, and the most important thing is the ability to handle user's requests if the site's traffic increases. I want to create an algorithm that users who watch others videos earn points (randomly but in clear context) If you have anything else to improve, please let me know. For eg: If you prefer React to Vue.js. Thanks in advance

      I'm working as one of the engineering leads in RunaHR. As our platform is a Saas, we thought It'd be good to have an API (We chose Ruby and Rails for this) and a SPA (built with React and Redux ) connected. We started the SPA with Create React App since It's pretty easy to start.

      We use Jest as the testing framework and react-testing-library to test React components. In Rails we make tests using RSpec.

      Our main database is PostgreSQL, but we also use MongoDB to store some type of data. We started to use Redis 聽for cache and other time sensitive operations.

      We have a couple of extra projects: One is an Employee app built with React Native and the other is an internal back office dashboard built with Next.js for the client and Python in the backend side.

      Since we have different frontend apps we have found useful to have Bit to document visual components and utils in JavaScript.

      How developers use React and UDash
      Avatar of Instacart
      Instacart uses ReactReact

      Before two weeks ago or so, it used to be Backbone views and models, and everything was on our main store app, and our mobile web app, but actually, we just switched our mobile web app to using ReactJS for the interface. So it鈥檚 using Backbone models but ReactJS front-end components. Really, it was borne out of the frustration with how the Backbone model-view bindings worked, and it wasn鈥檛 especially performant for large views, and we had to do lots of tricks to make it performant. But swapping that out with React views meant that it could be both simpler and faster without having to spend a lot of time on that.

      One other interesting thing about that is, since React actually works okay with the Backbone models and the Backbone router and stuff like that, we didn鈥檛 have to rewrite the mobile web application and update it to ReactJS. Rewrites are almost always a bad idea. We were able to upgrade pieces of it at a time, move on to React, and now the entire thing is using React and just has the Backbone router and models and stuff like that that we already had, so it's a lot faster.

      Netflix uses ReactReact

      At the beginning of last year, Netflix UI engineers embarked on several ambitious projects to dramatically transform the user experience on our desktop and mobile platforms. Given a UI redesign of a scale similar to that undergone by TVs and game consoles, it was essential for us to re-evaluate our existing UI technology stack and to determine whether to explore new solutions. Do we have the right building blocks to create best-in-class single-page web applications? And what specific problems are we looking to solve? Much of our existing front-end infrastructure consists of hand-rolled components optimized for the current website and iOS application. Our decision to adopt React was influenced by a number of factors, most notably: 1) startup speed, 2) runtime performance, and 3) modularity.

      React has exceeded our requirements and enabled us to build a tremendous foundation on which to innovate the Netflix experience.

      Web-frontend programming prior to React: like banging rocks together. With React: Like wearing fusion powered underwear. Gives you a nice warm feeling. Using React for Cloudcraft.co allowed us to create a beautiful UI in record time (1 month start to launch), with virtually no bugs popping up during development. The functional approach to just rendering your component given a state just makes so much sense, with React figuring out the delta between your current and desired representation. It's the future kids!

      React is choice number 1 when it comes to JS development at Kurzor. We choose React because it solves many issues with web applications in a elegant way. Writing an app in components is useful for coordination and isolation of concerns. React forces you to abandon state and use vertical passing through props instead. And having as many Pure Components as possible helps to write cleaner code.

      With React we usually use: Redux, React Router, React Toolbox, Styled Components.

      This is the best component framework and API available today for building modern web sites and apps. I really enjoy how minimal it is, and powerful at the same time. It removes opinionated development and replaces it with logic and data philosophies, which has in turn fostered a robust and lively code and support community.
