React.js Efficient Server Rendering – Hacker Noon

  • React.js Efficient Server RenderingFor about a year now I’m developing Web Applications based on React.js, and it was amazing for me to write code that actually scales with JSX components, rather than functions, it’s giving more simplicity to frontend.But in some cases we need SEO with dynamic JSX content or we need more performance in load time for a frontend pages.
  • And for that cases Facebook developers made React.js in that way so it can be rendered on Server Side too, using Node.js basic functionality.So the flow is almost similar to this oneClient sending request to get some JSX template pageNode.js server getting main file containing JSX codeRendering it to plain HTML codeSending HTML response to clientUsing HTML markup, then client loading also React.js client side code for adding dynamic logic to rendered HTMLThis is helping to display HTML content faster than React will render it, and it is helping to give some content to Search Engine bots or website crawlers.But What If You Don’t Have Node.JS backend?This is the real questing that was standing for me when I’ve started working on large Python Django project.
  • I decided to do React.js as a frontend, but they hat a lot of Python stuff on a backend, I couldn’t rewrite all code just for server side rendering.

React Native Performance

#ReactNative performance and some tricks & tools to optimize your React Native application:

  • Every character typed in the Native component involves the physical event, transforms it in letter or action, and then transmits it by the bridge to the JS component.
  • In all of the transactions of data between JS and Native, the Bridge always intervenes so that the data is included in both parts.
  • The Animated library has been created to improve the performance of the animations, and its objective is to lighten the use of the bridge by sending predictions of the data to the native before starting the animation.
  • Thankfully, the Bridge isn’t the only one at fault, and there are many other ways to optimize a React Native application.Therefore, here is an exhaustive list of why and/or how you can optimize your application:

    The React Native “tooling” is not yet very developed, but a great part of the toolset is that itis coming from the application.

  • The performance of a React Native application is very important.

Reactive Core architecture for React Native and React applications – KuraLabs Engineering

Reactive Core architecture for React Native and #ReactJS applications:  #JavaScript

  • Reactive Core architecture for React Native and React applicationsWhen it comes to develop an application that needs a mobile app and a web app, there is always a struggle in the matter of what is the right approach to take.
  • Nevertheless, even though these frameworks solve code reuse between mobile platforms the problem to reuse functionality with a web application remains.This article proposes an architecture “Reactive Core Architecture” that allows to have just one code base for the logic and keep the native UI and the web UI separated, maximizing code reuse and maintaining consistency across platforms.Some of the advantages are consistency, code maintainability, testing gets easier and performance is high.
  • React Native is used for the mobile application and React is used for the web application.Redux “is a predictable state container for JavaScript apps”, that means the whole state of the application is stored in an object tree.
  • Code reuse is done via this module.The mobile app: Implemented as a standard React Native application, using containers and components.The web application: Implemented as a standard React application, using containers and components.Each module will live in its own repository, with the core as a git submodule in both applications.Let’s take a look to the architecture diagram:Consists on a basic Redux structure, meaning you have a folder for the actions and a folder for the reducers.root├── actions└── reducersThis is the most important module to make the Reactive Core Architecture possible.
  • Since each reducer handles an specific part of the application state, it makes easier for the core module to scale for larger and more complex applications.The mobile app and the web app.Both the React Native app and the React app, use components and containers concepts.

When it comes to develop an application that needs a mobile app and a web app, there is always a struggle in the matter of what is the right approach to take. You can build a web app and a native…
