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.

Mapbox GL JS + React – Points of interest

Mapbox GL JS + React  #react #product #frontenddevelopment #redux #javascript #reactjs

  • What’s shown to the user when a component calls render() is conveniently managed internally allowing an implementor to work on higher level tasks like how an interface behaves.What can be confusing is connecting React with other libraries that manipulate the DOM and manage state (like Mapbox GL JS).
  • The wrapper permits customization like size or title, and the technical details that should always be the same (event handling of key bindings or accessibility) is tucked away in the lower level modal component.So it’s natural to look for a Mapbox / component within the React ecosystem (see react-map-gl or react-mapbox-gl as example).
  • The map is initialized within componentDidMount and its container value is set as the assignment of this.mapContainer which is React’s way of providing direct access to the DOM node.Let’s explore some more in-depth examples:Basic exampleSee full example on GitHubIn this example, React passes position data as state to the map.
  • This could also be prop data passed from a higher level component but in the interest of containing the entire app as one component I’ve used state.Reactive tooltip exampleSee full example on GitHubThe details to note are:Data found in vector tiles is collected under the mouse cursor using queryRenderedFeaturesA mapboxgl.Marker instance is used to display the collected data on the map (Mapbox GL JS controls its position on the map) but the contents of the marker is React powered using ReactDOM.render.Fetching map data like this isn’t exclusive to tiles directly from Mapbox.
  • To learn more how we use Redux in Mapbox Studio, check out, Redux for state management in large web apps by David Clark.I hope this helps as a primer on using Mapbox GL JS alongside React and provides some context for how we achieve a few different concepts here at Mapbox.

When we build web applications at Mapbox we often turn to React and Mapbox GL JS. The goals of each library work powerfully in combination and I’d like to share some techniques into how we approach…

Why build your forms with Redux Form – DailyJS – Medium

Why build your forms with #Redux Form:  #ReactJS

  • Why build your forms with Redux FormWhen I usually create forms for my React/Redux applications I tend to keep the value of the inputs on the application state, with little to no editing, (because my forms are usually simple), I never stopped to realize what that means.
  • It also receives an event handler that will update the state when the user interacts with it.It means that when the user types the letter “J” on the input, what is visible is not the same “J”, it may be an identical “J” that comes from the state, or whatever the event handler has put in there.Ok but, that doesn’t answer the first questionBy having all the application state in the JavaScript app and using controlled components we get a single source of truth and take full control over the application behavior.In the context of a form, our React component is able to:do instant validation;control the input value format;enable, disable, show or hide components given the state;handle dynamic inputs.Although it is highly recommended to use controlled components, it is also good to point the drawback that you will have to create event handlers for all your inputs and that may be a bunch of code that doesn’t make sense to the application.What about Redux Form?Now that is known why to keep the form data in the state and you reason if that makes sense for your application we can come back to our main subject.
  • It keeps track of all common application form state such as:The fields that are in the form;The values of each field;The focused field;If the field values are valid;The fields that the user have interacted with;If the form is being submitted;If is happening any asynchronous validation.Let’s take a look at a bit of code and see how to do a setup.Here we connect the form component to Redux by decorating it with the high-order component reduxForm.
  • It will also hand us the handleSubmit function, which will take care of the submission behavior.The Field component takes our input component as its props and acts as a container, bringing the application state to the input component and binding the event handlers to update the state in store.Look at the InputText component to see the props we receive from the Field.One important point is that it’s still a developer’s responsibility to write the form and inputs components, this way the library does not take the flexibility from you to manage the behaviors of your form the way you want, or even add custom ones.And to finish our integration we add a reducer that will handle the state changes of your form.Simple isn’t it.Just one more point.
  • Look that the default value of the input is defined when the high-order component reduxForm is called and comes to the input within the prop input and not from the react’s prop defaultValue, this way we guarantee that our form values are all represented in the application state.In summary, having all your form data in application state gives you control over its behavior and you can easily implement that on a React/Redux application with Redux Form.I have created a repository on GitHub with the implementation above.

When I usually create forms for my React/Redux applications I tend to keep the value of the inputs on the application state, with little to no editing, (because my forms are usually simple), I never…

Why Do Developers Now Compare Vue.js to JavaScript Giants Angular and React?

  • It was 2016 when Vue.js rose to fame and gained so much traction that it’s now seen as an alternative for even well established JavaScript libraries, such as Angular and React.
  • Since Angular belongs to search engine giant Google and React comes from social media behemoth Facebook, developers still trust and use those libraries more than Vue.js.
  • This blog attempts to shed light on why there is a growing belief among developers that Vue.js is set to become the top JavaScript library, leaving behind Angular and React.
  • The reason many developers are turning to Vue is that it addresses the issues of React and Angular.
  • But, one must not forget that Angular and React are still very big names in the JavaScript world, whereas Vue has just begun to rise.

Vue.js, an MIT-licensed open source project, is a JavaScript library for building web interfaces. The library was first released in 2013, but not many developers took cognizance of it in web framework technology for the next two years. It was 2016 wh
