Fast websites drive sales: stay under 3 seconds

Milliseconds matter. Make your website load under 3 seconds:
 #ux #usability #reactjs

  • A fast responding website keeps your users happy, helps drive sales for e-commerce, gives you better SEO ranking and also saves you a buck on infrastructure.
  • A normal usability rule, coined by Jacob Nielsen, is to stay under 0.1 seconds for response time and the system feels instant for the user.
  • About 10 years ago Amazon published the remarkable statistics that for every 100ms of latency on their website it costed them 1% in sales.
  • Better search engine ranking drives more traffic to your website.
  • By having lower response time it usually means that you have a lighter running web App.

Stay ahead of the game and make sure your website or webshop is fast. A fast responding website keeps your users happy, helps drive sales for e-commerce, gives you better SEO ranking and also saves you a buck on infrastructure.

Understanding React — Component life-cycle – Bartosz Szczeciński – Medium

Understanding React — Component life-cycle

☞ 

#Reactjs #programming

  • In all other instances remember to use this.setState – DO – set initial stateif not using class properties syntax — prepare all class fields and bind functions that will be passed as callbacksDON’T – cause any side effects (AJAX calls is a somehow special case — componentWillMount does not differ much from constructor -…
  • DO – update state via this.setStateperform last minute optimizationcause side-effects (AJAX calls etc.) in case of server-side-rendering onlyDON’T – cause any side effects (AJAX calls etc.) on client function will be called in each update life-cycle caused by changes to props (parent component re-rendering) and will be passed an object…
  • DO – use for increasing performance of poor performing ComponentsDON’T – cause any side effects (AJAX calls etc.)call nextState)If the shouldComponentUpdate function is not implemented, or it decided that the component should update in this render cycle, another life-cycle function will be called.
  • == this.props.myProp) { – // this.props.myProp has a different value – // we can perform any operations that would – // need the new value and/or cause side-effects – // like AJAX calls with the new value – this.props.myProp – } – }DO – cause side effects (AJAX calls etc.)DON’T…
  • DO – cause side effects (AJAX calls etc.)DON’T – call this.setState as it will result in a re-renderAn exception to the above rule is updating the state based on some DOM property which can be only computed once a component has re-rendered (e.g. position / dimensions of some DOM nodes)….

React provides developers with many methods or “hooks” that are called during the life-cycle of an component, which allows us to update the UI and application state. Knowing when to use which of them…

The React Podcast by Changelog Media on Apple Podcasts

  • Most saliently, you called his framework “React Native Web” over and over again despite him saying “React Native for Web” every single time.
  • Whatever you thought the framework’s name was going into the interview, and for whatever reason you thought it, when your guest describes their own work with one name USE THAT NAME.
  • For example, he clearly said his problem with the CSS framework replacing the Style object was that it would add overhead, not that it would make low-level styling impossible (no web framework has that power unless it’s malicious).
  • His point was that if you’re writing a framework that does low-level CSS operations under one paradigm (React Native for Web), it’s wasteful to load an entirely different framework that does the same work under a different paradigm (CSS framework).
  • Please, either listen better, or after the interview ask the interviewee if they’d like you to preamble the podcast with any corrections of what you said.

So you want to learn React.js? – EdgeCoders

So you want to learn React.js?

☞ 

#Redux #javascript

  • This is a good thing, React is a library that does one thing really well, but it’s not the answer to everything.
  • This is not counting the tools and other libraries that complete React like for example, Redux or Relay.
  • Refreshing your knowledge on JavaScript first would not hurt, specially because you need to learn ES2015, not because React depends on it (it does not), but because it’s a much better language, and most of the examples, courses, and tutorials you’ll find use the modern JavaScript syntax.
  • The recommended tool is Babel.jsReact ecosystem libraries: Since React is just the UI language, you’ll need tools to complete the picture and go beyond even MVC.
  • I’ll give you two things to focus on, just forget everything else you encounter and learn these two first once you’re done with React itself: react-router and redux.Right after getting comfortable with the raw concepts of React itself, build a React Native app.

First, make peace with the fact that you need to learn more than just React to work with React. This is a good thing, React is a library that does one thing really well, but it’s not the answer to…

Front End v. Back End Explained by Waiting Tables At A Restaurant

  • Front End v. Back End Explained by Waiting Tables At A RestaurantIf you have ever visited a sit-down restaurant, then you can understand the difference between front-end and back-end in web development.
  • Here’s the general idea: just like there is a waitstaff and kitchen staff in a restaurant, front-end and back-end divides the functionality of your site.
  • In web development, the front-end is also sometimes called the client-side, while the back-end is also called the server-side.
  • They must be able to quickly browse to see what you offer (HTML/CSS)They must be able to quickly find more resources that will help them make a decision (Interactivity/JavaScript)They must be able to take an action that will lead them closer to their goal (User Request/ JavaScript)An Intro To The Back-EndHave…

Get Rich Quick With React Context

Slides from my talk at #reactfinland about #reactjs context:

  • So when my advertising provider component is initialized, it constructs an internal advertising module with my configuration.
  • It configures my ad slots with my ad server.
  • When one of my advertising slot components mount, they call an activate function that is passed to them by the provider.
  • This causes my advertising module to tell the ad server: OK, go ahead and fill that slot with some advertising creative.
  • The ad server then uses a system called Prebid to make an online auction to sell the advertising space to the highest bidder.
