Ivan Linko’s answer to How good is ReactJS for building e-commerce websites?

  • A common E-commerce website usually comprises a plethora of forms to fill, complex filters, elements, which interact with different APIs, maps, etc.
  • With the help of React you can easily implement all of those features, making it a good option to build highly interactive E-commerce websites.
  • One of the great things about React is that it allows for a rather convenient way of storing and manipulating the state of your app (e.g. filtering through items is a change in the state of the app).
  • What’s more, React comes with a whole bunch of ready-made modules for all occasion, not mentioning that it’s easy to test and scale.
  • We’ve used React in some of our E-commerce projects and it recommended itself as a very mature and versatile technology.

Why ReactJs? – (┛◉Д◉)┛彡┻━┻ – Medium

Why ReactJs?  #react #reactjs

  • Instead of writing an html line for news, messenger and marketplace you can see that they are basically the same, the only thing that changes is the icon and the information so we can make a component called nav that receives information and an icon.
  • Let code this component:First, we are going to make its container, with an JSON object with the information we want to be see.Now we are going to do the component:Using this practice, we are able to create a web app by just iterating a JSON object, that will pass the information to the containers.Another cool thing of react is its community.
  • There is a lot of components already made so you can just add them to your project as easily as adding a library to your normal html code.
  • Some github repositories that have a lot of components are:· lot of people have a problem with HTML being mixed with JS because they feel like breaking separation of concerns but in reality, it is more of a separation of technologies rather than concerns.
  • It helps your application to be more efficient because you don’t need to repeat code, there is an amazing community behind it, it has some really awesome modules that helps you to manage the unidirectional data flow, as well as managing which component must be render and if it is a component that is visible in all of the pages such as a menu to just render it once instead of every time you change of page.Tldr: react is awesome.

React is a new JavaScript library developed by Facebook released in 2013, but it wasn’t until 2017 that react was stable. React is like the best of both worlds, it has the functionality of JavaScript…

Using Props in React – ziv zamechek – Medium

Using Props in React  #javascript #react #reactjs

  • In between the time it takes the first render of the component to fetching this data and setting it on our state that takes some time and during that time the length of videos is equal to 0 that is the reason that we see 0 for half a second when refreshing the page.
  • this.state = { videos: [] };When it is first rendered it does search of surfboards and it gets the response from this.stateApp is the parent of video list and video list need to get access to the videos that are in the app state.
  • passing data from the parent component App to the child component VideoList we are passing the list of videos just by defining a property on the JSX tag.Here we are passing video list to render method.
  • Anytime when App re render VideoList will get the videos as well.So now we have a functional VideoList component and it has array of videos to render.
  • Our video list component will receive props that contain an array of videos so we just loop over this array and for each video will generate one instance of video list for each item.Now each VideoListItem which is intended to show a single video now it will show a single li with a video.A map is a built in method that is a property of an array.

When we use functional component the props object will arrive as an argument to the function. const videos = props.videos; this is the array of videos. {props.videos.length} so this is saying that…

Intro to React.js – Agata Krzywda – Medium

  • Intro to React.jsFor the past few months I have been learning react.js by doing a lot of online courses, tutorials, going to workshops and most recently attended to awesome react flipflops course run by Maciej Nowakowski.I learnt a lot on the way and now I am putting together this tutorial with the aim of it being the one tutorial I wish I had when I first got started.This is a introduction tutorial of my series of ’’intro to React.js’’.
  • Editing text on the pageOpen App.js this is your main react component.
  • Create new componentCreate new file in src folder call MyComponent.jsThis is a simple component which says ‘Hello World!’
  • To use that component in App.js we need to import it at the top of the file.import MyComponent from ‘.
  • Using state and methodsIn class components for example App.js we can use state to store informations about our component.State is an object and can give it initial values in constructor, e.gthis.state = { isOn: true };You can access to state in render method using this.state for example if we want use isOn property we get it from this.state.isOnThe button text is determined by the current value isOn property.button{ this.state.isOn ?

Nishant Agrwal’s response to Why isn’t React called framework? What does it lack to be a framework?

Why isn't React called framework? ⚛  #ReactJS #JavaScript @reactjs

  • It is a framework in the sense that it absolutely does have a predefined architecture and infrastructural design and it calls into your code to fill in the details.
  • It is the framework code that runs first and that calls into your code to determine what has to be done at a high level.
  • The difference between a library and a framework has to do with Inversion of Control .
  • The code written by the user of a framework just defines in an abstract way the specifics of that particular application.
  • At the end of the day it is more important to understand how React is different from the classic examples of either a library or a framework.

React and third-party libraries

#ReactJS and third-party libraries:

  • It uses the Tags component that displays an unordered list based on the passed tags prop.
  • Component { render() { return (
      { this.props.tags.map((tag, i) =>

    • { tag }
    • ) }

    ); } }; // App.jsx class App extends React.

  • The very first thing that we have to do is to force a single-render of the Tags component.
  • class Tags extends React.
  • Every time when we click the button we update the state and trigger rerendering of Tags component.

React in patterns project. For other interesting patterns check out the repo.The example jQuery plugin for my example. It transforms an unordered list to input field for managing tags: plugin code. It works like that:. class. It uses the component that displays an unordered list based on the passed prop. When React renders the list on the screen we know that we have a tag so we can hook it to the jQuery plugin.Force a single-render component. That’s because when React adds the elements in the actual DOM we want to pass the control of them to jQuery. If we skip this both React and jQuery will work on same DOM elements without knowing for each other. To achieve a single-render we have to use the lifecycle method like so: here we are saying that our component will never rerender. If defined is used by React to understand whether to trigger or not. That’s ideal for our case because we want to place the markup on the page using React but we don’t want to rely on it after that.Initializing the pluginAPI for accessing actual DOM nodes. We have to use the attribute on a node and later reach that node via . is the proper lifecycle method for initializing the plugin. That’s because we get it called when React mounts the result of the method. lead to React rendering the with two items and then transforms it to a working tag editing widget.Controlling the plugin using React field. Such action will be triggered by the React component and needs to use the jQuery API. We have to find a way to communicate data to component but still keep the single-render approach. class and a button which if clicked will pass a string to component. component. However, because of we update nothing. The only one change is that we get a value of the prop which may be captured via another lifecycle method – : is a pure jQuery code. is a nice place for calling methods of the third-party library. component:Conclusion / blog of Krasimir Tsonev – front and back-end developer who writes for web technologies
