React JS and PHP Restful API User Authentication for Login and Signup.

React JS and PHP Restful API User Authentication for Login and Signup.

  • Today’s post explains how to implement login authentication system for your React JS applications.
  • It will show you how to log in with a user and store the user session, so it deals with token-based authentication.
  • Since we are using token-based authentication, it protects if any unauthorized request is made and notices for a new login if required.
  • This makes your application’s authentication to be more secure compared with any other authentication system.
  • Hope you’ll find it more easily using this as your authentication system in your ReactJS projects.

Learn Redux by coding a Mini-Redux – Jakob Lind

Do you think Redux is complicated? Learn Redux by coding your own mini-redux  #reactjs

  • The whole point with Redux is to have one single source of truth for your application state.
  • The state is stored as a plain Javascript object in one place: the Redux Store.
  • When Redux is used with React, it is the React components that get notified when state changes, and can re-render based on new content in the store.
  • We can copy/paste that example to test our own Redux implementation: – – Get the full code to run it on your machine by signing up to my email list below!
  • In the next blogpost, we will code the connect function which binds your Redux store to React components.

There are lots of resources for learning Redux. There is the official documentation, examples, tutorials, blog posts, boilerplates, Youtube videos, podcasts, etc… The list goes on. Even though we have so many great resources to learn from, new developers coming in still sometimes gets confused. It’s an overwhelming amount of content and it can be difficult to filter out the relevant stuff.

Getting out of a .bind() – Frontend Weekly – Medium

Getting out of a .bind()  #babeljs #react #javascript #reactjs

  • bind()Thanks to class properties, never bind “this” to methods in class constructors again. 🎉The ShortInstead of this:class MyClass extends React.PureComponent { constructor() { this.myFunction = this.myFunction.bind(this); } myFunction() { const { myVar } = this.props; } … etc}With class properties enabled in Babel, bound class methods are simple:class MyClass extends React.PureComponent…
  • However, after clicking the “increment” button you’ll see the increment method throw an error:Cannot read property ‘state’ of undefinedWeird, why could ‘render’ access state but not ‘increment’?
  • React’s lifecycle methods are automatically bound to the current component instance, so render can access this.state.count.
  • The problem is any component method we create is not automatically bound.To fix the problem, we write this unintuitive line of code:constructor() { super(); this.state = { count: 0, } this.increment = Fields / Properties to the RescueClass Fields are a stage 3 proposal that you can use right now with…
  • With this proposal, these two class variables are declared in the context of the class instance, aka this.Thus, the this.state = {} inside of the constructor method is analogous to state = {} outside of the method.In the case of increment, we set an arrow function which inherits the lexical…

Everything renders correctly on load and render is referencing this.state.count as expected. However, after clicking the “increment” button you’ll see the increment method throw an error: React’s…

6 Pro Tips from React Developers — SitePoint

We've got 1 #reactjs tip from a pro devs for you. Watch  for all 6 tips.

  • Tip 1: Use functional components – Cam Jackson – If you don’t need internal state or lifecycle methods on your component, use a functional component instead.
  • A functional component is a pure JavaScript function that accept props as its argument and returns a React element.
  • Benefits of functional components: – – Less code – Easier to understand – The component is stateless, so you avoid accidentally storing state on a component you shouldn’t – The component is simpler to test – There’s no this binding – It’s easier to see where and when to extract…
  • Keep Tip 1 in mind and extract blocks of code into functional components whenever possible.
  • Tip 6: Use React Developer tools – Brian Gates – With React Developer Tools, available as a Google Chrome and Firefox extension, as well as a standalone app for other environments, you can quickly view your component hierarchy, inspect and edit a component’s props and state, and invoke methods on…

If you’re new to React, you could benefit from learning from React developers who’ve learned valuable lessons about the framework.

5 Best JavaScript Frameworks in 2017

  • In the meanwhile, JavaScript web frameworks can become a silver bullet for quick web app development.
  • Angular.js is often referred to as an MVW (Model-View-Whatever) framework and among the top benefits, for startups and mid-sized companies, people name: quick code production, easy testing of any app part and two-way data binding (changes in the backend are immediately reflected on the UI).
  • As for now, it is reasonably called the most used JS framework for SPAs (Single-Page Applications) development and it boasts the largest community of developers.
  • Back in 2015 Ember was called the best javascript framework for web application, leaving behind React and AngularJS.
  • When it comes to quick web development or prototyping, JavaScript frameworks are among the most favorable and 2017 won’t become an exception.

JavaScript popularity continues its rising. In 2016 we’ve witnessed such great changes, as AngularJS entire upgrade and introduction of Angular 2, ultimate dominating of jQuery that is applied on 96.5% of all JS sites, evolution of ECMAScript, two updates of Node.js in April and October accordingly, React finest hours, and even more.  What to expect from 2017?

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

ADB is server is out of date, killing … – Bilal Bayasut – Medium

ADB is server is out of date, killing …  #android #adb #reactnative #reactjs #reactjs

  • Genymotion comes with its own adb in the tools/ directory, which is version 1.0.32 if you are running the latest Genymotion, currently 2.3.1.
  • Unless you changed it in the settings, Genymotion will start the bridge with that copy.Since adb operates in a client-server arrangement, the client version should match the daemon version.
  • If the daemon is killed or dies, the Genymotion launcher automatically and immediately restarts adb (using its own copy), and that’s why your client can’t start a new daemon bound to port 5037.
  • The solution is to make sure that the version of adb you are invoking on the command line matches the one that Genymotion is bringing up as a daemon when it starts the VMs.
  • The easiest way to ensure this is just to use the adb binary in Genymotion’s tools/ directory.Note that if you have changed Genymotion’s default of using its own tools to use custom SDK tools, then you’ll need to use an adb client that matches the version contained in the SDK…

Again, just a note for my future self. Someday I installed android studio in my ubuntu 16.04 elementary os based machine. Then I install npm, react-native and genymotion. But when I try to emulate it…
