Ext JS to React: Advanced Templating

  • Previously, we looked at simple template examples with Ext JS and React.
  • This includes the use of member functions and inline value formatters from Ext JS and how the same techniques are accomplished with React.
  • The equivalent changes in React would be: – – To use the Members class (with the same data we set up for the Ext JS example above): – – In JSX, anything between curly braces can be JavaScript.
  • The method is akin to using “template member functions” in Ext JS’s XTemplates.
  • Although this isn’t required (it’s preferred to keep inline for such a simple check), it still serves as a good example of calling class methods within JSX.

Previously, we looked at simple template examples with Ext JS and React. In this blog, we’d like to look at some more advanced examples. This includes the use of member functions and inline value formatters from Ext JS and how the same techniques are accomplished with React. For consistency, we’ll use the same data set defined in the Simple Templating post.

Introducing the React RFC Process

  • We’re adopting an RFC (“request for comments”) process for contributing ideas to React.
  • It’s also intended to provide a clear path for ideas to enter the project: – – RFCs are accepted when they are approved for implementation in React.
  • As a rule of thumb, this means any proposal that adds, changes, or removes a React API.
  • We now have several repositories where you can submit contributions to React: – – Coinciding with the launch of our RFC process, we’ve submitted a proposal for a new version of context.
  • The proposal has already received many valuable comments from the community that we will incorporate into the design of the new API.

Inspired by Yarn, Ember, and Rust, the goal is to allow React core team members and community members to collaborate on the design of new features. It’s also intended to provide a clear path for ideas to enter the project:

Going Over The Speed Limit

  • * Given in React Native EU (Poland) on Sept 6, 2017

    Asynchronous rendering is one of the core principles of React.

  • The same architecture seems to do miracles in React Native and gives JavaScript the performance boost needed to render native views effectively.
  • This benefit of React Native is also its greatest drawback.
  • For certain types of problems in native mobile, asynchronous rendering introduces an overhead that is almost impossible to bridge.
  • Is it possible to introduce synchronous rendering to React Native and tackle this category of problems from a different direction?

Asynchronous rendering is one of the core principles of React. On the web, the ability to batch updates and work on a virtual DOM proved to be key factors in improving rendering performance. The same architecture seems to do miracles in React Native and gives JavaScript the performance boost needed to render native views effectively.

Thinking in React by radubrehar #javascript #reactjs via JavaScriptKicks

  • Yet the render method, the component props, and the component state are the most important things in a React app – getting a good grasp on these paves the way for productively using React in commercial apps.
  • In the above example, notice how state is updated with a new address object on every change – this avoids skipping updates when is used – which is just a React component that only re-renders when it receives new values for props and for state (it shallowly compares the old and new props objects and the old and new state objects).
  • Another powerful concept in React apps is controlled props – it basically means components don’t store any intermediate state for the controlled props (for example on updating the value inside a text input), but rather on every change, they notify the owner component of the change, so the owner can re-render the controlled component with updated values for the props.
  • The above inputs are example of controlled components (already baked into React), but basically this is the gist: uncontrolled components use their internal state to update their UI, while controlled components always show values from props.
  • And the beauty of it is that in almost no time you can become productive in building native UIs for mobile or desktop operating systems, or even for the webVR now that React is becoming widely adopted, with libraries written to target multiple platforms, but with one common way of thinking about UIs – declarative and component-based.

React is different in so many ways from its front-end predecessors. But the most different part is its way of thinking. Read on to find out more!

Skype is testing a new Android app with a new design, reaction feature, and Bing integration

  • The software giant recently released a new Skype Preview app on Android, for those part of the Skype Insiders program.
  • If you have used the new Skype Preview app on Windows 10, you’ll notice that the icons on the new Android app are exactly like the ones on the Windows 10 app which is pretty great to see as it improves the consistency of the service’s design — which, to be honest, is still lacking on some Microsoft services unfortunately.
  • As for the features of the new Skype, you will get almost all of the features that are on the old Skype app — but Microsoft has added some neat new features to the new Skype app.
  • Microsoft says the company will be adding more tools like this in the near-future — which you’ll presumably be able to activate if you want:

    As you can see in one of the screenshots above, Microsoft has also added a new “react” feature that essentially lets you react to a message in a conversation.

  • The new Skype app for Android is looking really good at the moment, and it’ll likely get rolled out to more users in the coming months.

Skype’s Android app is a fairly well-designed app with a bunch of features that is pretty great…when it works. Skype apps across different platforms have some issues, although Microsoft has done a pretty good job at fixing some of the issues when the company moved to a modern infrastructure. The Skype UWP app on Windows 10 is a good example of the “modern Skype” that works pretty great for the most part, but it isn’t full-featured just yet. And now, it looks like Microsoft is working on a similar reboot for the Skype app on Android.

ReactJS Seed Application: Why Not Start with the Real Deal?

#ReactJS seed application: Why not start with the real deal?

  • Looking at the most common React seed applications you will see that they have, for each component, a custom folder and they group them all as components.
  • Everyone knows if you google for “React seed application” or “React boilerplate” you will find tons of prebuilt seed applications out there, some of which are being used by thousands of people.
  • Selecting Browserify as our initial stack is a very good example of why a seed application can be useful.
  • After looking at these, we found that though a lot of them offered unique and interesting concepts, none of them seemed very scalable to us for use in large web applications.
  • For one, a seed application allowed us to try out different libraries and project structures without the restriction of a particular use case.

Hyperwallet’s Software Development Team Lead looks into tools for building their final browser version in ReactJS.

  • The virtual DOM in this case is the data and not the rendered content React.js is able to determine the pieces of data that have actually changed in great detail.
  • It has a data binding and state management feature that makes it an ideal platform for creating dynamic applications.
  • Many web developers will not have this, as speed is key whenever you are creating applications.
  • React.js is currently amongst the best JavaScript UI framework that a lot of web developers are finding useful in many ways.
  • If a certain change is made on the data upstream, the components using that particular data will automatically re-render in order to reflect the changes.

Facebook tries a new way to release open-source projects

Facebook tries a new way to release open-source projects:  #ReactJS

  • The same goes for projects that Facebook is donating to larger organizations like the Open Compute Project.
  • You shouldn’t think of projects in the Incubator as a repository for weaker projects, he noted.
  • Facebook tries a new way to release open-source projects
  • The Facebook Incubator is the company’s new process for releasing open-source projects and ensuring that they do well .
  • Not every project turns out to be a success, after all, and occasionally Facebook ends up sunsetting some of the tools it open-sourced.
