Case study of SSR with React in a large e-commerce app – Jakob Lind

Case study of SSR with React in a large e-commerce app  #ReactJS

  • In this case study you will learn: – – In this case study, I present how we have implemented SSR (server side rendering) with React in an e-commerce application for one of Norway’s largest telco brands Telia.
  • What we have learned over the 3 years we have worked with the app is that keeping things simple helps a lot when implementing and maintaining an SSR solution.
  • The theory of SSR is pretty simple: you just render your React components on the backend and send the generated HTML to the client.
  • We create our Redux store with the initialState on the backend like this: – – The initialState variable is also sent to the frontend in a global variable so that the client side app gets the exact same state prefetched.
  • Here are some examples of variables that we guard against on server side: – – The process for knowing when to add the guard is something like: – – We are also careful to only use dependencies that work with SSR.

Setting up SSR (server side rendering) with React is painful. There is no good overview or starting point. Instead, you have to gather pieces of information from googling and do your best to puzzle them together.

Creating React Native apps with Django rest-api

A app developer shares how to create React Native apps using Django

  • In this blog post, I am going to share basic steps for developing a React Native app with Django rest-api.
  • I have been mostly developing native mobile apps But sometimes it seems like time consuming to develop a simple app with same functionalities for both iOS and Android.
  • Finally, we create an api function in views.py which will server requests at /api/list end poin_t_ – – We are ready for creating our React Native app now.
  • You can try out expo APIs here – – In Short, React Native is powerful framework for building iOS and Android apps.
  • Find the full source code of React Native app (PyconLunch) on Github.

This blog post explains about creating a simple React Native app with modern tools and packages.

How to code your own procedural dungeon map generator using the Random Walk Algorithm

  • The larger the maxLength is compared to the dimensions, the more “tunnel-y” it will look.Next, let’s go through the map generation algorithm to see how it:Makes a two dimensional map of wallsChooses a random starting point on the mapWhile the number of tunnels is not zeroChooses a random length from…
  • push(num); } } return array; }To implement the Random Walk Algorithm, set the dimensions of the map (width and height), themaxTunnels variable, and themaxLength variable.createMap(){ let dimensions = 5, maxTunnels = 3, maxLength = 3;Next, make a two-dimensional array using the predefined helper function (two dimensional array of ones).
  • Because of this, the directions could be defined as subtractions from and/or additions to the column and row numbers.For example, to go to a cell around the cell [2][2], you could perform the following operations:to go up, subtract 1 from its row [1][2]to go down, add 1 to its row…
  • If within the loop the tunnel hits the edges of the map, the loop should break.while (tunnelLength randomLength) { if(((currentRow === 0) (randomDirection[0] === -1))|| ((currentColumn === 0) (randomDirection[1] === -1))|| ((currentRow === dimensions — 1) (randomDirection[0] ===1))|| ((currentColumn === dimensions — 1) (randomDirection[1] === 1))) { break; }Else set…
  • If so, set the lastDirection to the randomDirection and decrement maxTunnels and go back to make another tunnel with another randomDirection.if (tunnelLength) { lastDirection = randomDirection; maxTunnels–; }This IF statement prevents the for loop that hit the edge of the map and did not make a tunnel of at least…

As technology evolves and game contents become more algorithmically generated, it’s not difficult to imagine the creation of a life-like simulation with unique experiences for each player…

How The React Framework is Changing Front-End Development

An Introduction to the #React Framework @reactjs #webdev

  • If you’re looking for instant page loads, or the ability to handle long lists of dynamic content changing within the view, React may be the JavaScript library for you.
  • Enter React, an isomorphic JavaScript library released by Facebook in 2013, that allowed developers to use SSR to build modern web apps.
  • One of the reasons developers had started to drift away from SSR was that it was necessary to have to load the entire web page every time something changed within the view.
  • React introduced a workaround called the Virtual DOM that allowed developers to take advantage of the inherent performance advantage of SSR, without having to update the entire view every time a user made a small change to the UI.
  • React is a powerful UI library that brings the power of SSR, isomorphic JavaScript, and component-based web development to modern dynamic web applications.

React (also known as React.js or ReactJs) is a powerful JavaScript library that uses server-side rendering (SSR) to provide a flexible, performance-oriented, componentized front-end solution. If you’re looking for instant page loads or the ability to handle long lists of dynamic content changing within the view, React may be the JavaScript library for you. Read on to learn more about React.

7 Best Javascript Frameworks 2017 For Web Developers

  • Node.js provides server-side scripting feature as javascript Frameworks to runs server-side scripts to produce dynamic web page content.
  • Angular JS 2 stand among the most popular Javascript frameworks which is used by many developers to build and maintain complex web applications.
  • It contains different functionalities similar to other javaScript frameworks contains  which support other parts of the application in a form of services & also improves the existing modules into ES6 modules.
  • Vue collaborates with WEEX, which is a cross-platform UI framework which uses Vue as its best Javascript frameworks for runtime which helps to use same Vue component syntax as well as other components that cannot be rendered in the Browser & also natively on iOS and Android.
  • Hence, Many JavaScript frameworks offer innovative features to manage complexity in web applications with an integrated development toolkit that enables rapid iteration.

JavaScript is a scripting language used in web development to add dynamic and interactive elements to the websites using various Javascript Frameworks

Sharing React Components Easily with Bit — SitePoint

  • Bit is an open-source project that enables us to instantly share components from our existing source code with our team, and use them across our different projects without changing our source code, file structure or the tools we work with.
  • Sharing Components with Bit – If you haven’t heard of Bit’s latest release, it’s an open-source project that allows us to share components from our existing source code with our team and across projects.
  • By decoupling the representation of components from our actual file structure, Bit tracks the components within our source code and enables us to quickly turn any file or subset of files into a reusable component.
  • js – #Tracked 24 new components – – – – The next thing we want to do is to commit our changes: – bit commit -am ‘committed my first tracked code components’ – – – – The next step is exporting our components into a remote organized collection (Scope), sharing…
  • To organize your own components into shared collections, feel free to get started with Bit or visit the project on GitHub.
