How to build a server-rendered React app with Next & Express

  • Next, open up your package.json and replace your script section with this: – Run the npm run dev command, you should get an error like : – next Couldn’t find a `pages` directory.
  • Please create one under the project rootThis is because Next uses the pages directory and the files in them to map its routes.
  • Look at this route below, This helps us to achieve clean URLs as discussed in the paragraph above: – By default, it’s easy to use query strings in Next, but as usual, you want to keep your URLs clean, so you opt for something like: /p/2 rather than /p?id=2.
  • In the code above, we use the popular express routing to define such routes, then we pass the page that should be loaded and the id as a query param to the main Next app.
  • First, create a file called next.config.js in the root of your app and add the following content: – Note: In the setup above, only the index page would be exported as it is the only route we have specified in the PathMap.What if we want to add more pages?

Writing Easily Testable Code with Stateless Components in React.js

Writing Easily Testable Code with Stateless Components in #React.JS  #javascript #testing

  • By relying on pure components, developers end up writing reusable code that’s extremely easy to test, which leads to better application architecture.
  • Personally, I like the term “pure component” because it’s indicative of what the code really is — a pure function sprinkled with some JSX.
  • In addition to these benefits, pure components also make it extremely easy to test code with any crazy props that you wish.
  • Like a pure function, pure components will always map the same input to the same output, therefore, if we can think of the scenario, we can test how our component will react.
  • As we just saw, the code for functional components provides us awesome intel for everything we need to know in order to write effective tests.

Functional Stateless Components provides clean syntax that allows us to
write more declarative code. We will look at stateless components and finish up with some unit tests in this article.

Why is It Better to Use ReactJS over Others? – Aglowid It Solutions

Why is It Better to Use ReactJS over Others? 



#reactjs #ReactNative #React

  • If you hire ReactJS developer, they will not only create ultra-fast user interfaces but also with a simple Chrome extension, they can debug the codes.
  • Another advantage of using ReactJS development services is JSX.
  • Simply, JSX lets developers mix JavaScript and  HTML; with JSXTransformers, ReactJS turns all HTML tags into functions.
  • React-Native, also developed by Facebook in 2015 follows the footsteps of ReactJS to develop mobile applications for iOS, Android, and other platforms.
  • ReactJS with its Virtual DOM renders web pages on the server itself; and then sends it to the browser thereby making it easier for search engines.

React or ReactJS developed by Facebook back in 2013 is a JavaScript library that creates web interfaces which can change without a user reloading the page. If you hire ReactJS developer, they will not only create ultra-fast user interfaces but also with a simple Chrome extension, they can debug the codes. One of the prime…

React Higher-Order Component Patterns in TypeScript

  • An example might be a HOC which enforces that styles are set for a component via the style prop, a simple example of this being the following withBlueBackground HOC, which we’ll use throughout this article, and, as the name suggests, ensures the background colour is blue for the wrapped component:Note:…
  • : React.CSSProperties; name: string;}The type variable P is then used to specify the props for the unwrapped component to be passed into the HOC:UnwrappedComponent: is just an alias for React.StatelessComponentP | React.ComponentP, which would allow either a stateless functional component or a class component to be passed into the HOC.Object.assign()…
  • You will also face this same issue if you want to destructure the props using object rest:In terms of usage, the HOC can then be used as if it were a plain JavaScript HOC, with the added bonus that the wrapped component is statically typed:Pattern #2: Adding PropsSome HOCs add props…
  • : React.CSSProperties; name: string;}This will be more useful when additional props are injected, and ones which aren’t standard React props such as style.As for the HOC’s own props (WithBlueBackgroundProps) these are combined with the wrapped component’s props using a type intersection operator () :class WithBlueBackground extends React.Component P WithBlueBackgroundProps { …}This…
  • To demonstrate this with the withBlueBackground HOC, we will change it to require a component passed in that accepts a backgroundColor prop rather than setting the colour via style:Given we changed HelloProps to extend InjectedBlueBackgroundProps in pattern #2, no changes will need to be made to it, but the Hello…

Higher-order components (HOCs) in React are a powerful tool for code reuse between components. However, a common complaint of developers using TypeScript is that they are difficult to set types for…

React.js Overview via Alex Azarov  #webdev

  • Comparing React.js with Angular or other MVC frameworks makes no sense since React is just a representation.
  • Thus, a = b + c, and A will always depend on the values of B an C. – – React constantly works with the DOM, re-rendering it when conditions change (the part of the DOM that is changed by React.js is called a component).
  • Prior to React, such a practice would have seriously affected the application’s performance, but the developers of React.js approached this problem quite radically: they completely rewrote the DOM in JavaScript.
  • An important feature of React.js is the use of JSX.
  • There exist other extensions for React.js, however, considering the “weight” of the framework, their use should be minimized.

A discussion of the React.js web development framework, the pros and cons of this development tool, and who would be best suited using React in their projects.

Why Developers Love Node.js & what’s their main issue with it? Survey Results.

  • We were also interested in the infrastructural aspect of running Node.js apps in production, so we asked our readers to share where they deploy their services, what are their preferred front-end technologies, what kind of databases they use and which flavor of JavaScript they prefer.
  • Here come the results of our mini-survey: – – According to our survey, Node.js is a great option for developers who like to get their apps into production as fast as possible.
  • To understand why developers love & use Node.js, let me just show you a sample of the responses we got: – – When we asked developers about what they actually build with Node, the answers gave a pretty clear picture.
  • The answers were pretty hard to synthesise into coherent subgroups, but I tried my best in categorizing them: – – Although these answers are hard to categorize, I think they still provide useful insights into the problems & minds of Node.js developers.
  • The results were not surprising, the hegemony of AWS is clear: – – It looks like that React leads the front-end framework war – when it comes to Node.js developers who need to pick one: – – In case you’d like to learn more about it, read 8 Tips to…

539 devs who use Node.js in production told us why they love using it, what are they using it for, and what are the greatest problems they face with it.
