Reactjs vs Vuejs - What to Choose?
#Vuejs #Reactjs #js

  • Pros and cons of vue js
    Vue.js – is a JavaScript-framework that uses the MVVM pattern for creating user interfaces based on data models through reactive binding data.
  • A developer might not know how to use it but he should have heard about Vue js, because the framework became popular in past few years the number of use the words “Vue js” and “Vue.js” in Google trend in 2016 was more than in four times higher comparing to 2015.
  • Advantages of vue js:

    Having borrowed from older frameworks, such as Angular and React only the best, Vue.js stands the perfect balance between readability, maintainability of code and the pleasure of it, this code, writing.

  • From React Vue.js took a component approach, props, one-way data flow for the component hierarchy, performance, the ability to render on the backend and understanding the importance of proper state management.
  • This makes it easy to add the Vue library to the project, like jQuery.All this is possible in the React library, but generally the code written on React relies more on JSX and on the features of ES.

Both React.js and Vue.js have benefits and disadvantages, that may confuse a potential client at first. We’re going to make their comparison in this article.

No KISS for CSS-in-JS – Ivn Cote – Medium

No KISS for CSS-in-JS  #javascript #frontenddevelopment #css #react #reactjs

  • On top of that, CIJ tangles and confuses the many aspects of frontend development, thus contradicting the KISS principle and the UNIX design principle of making single purpose tools (programs).
  • Even more: despite the fact that CIJ is only a subset/superset of CSS, CIJ advocates like Mark Dalgleish tell us that the approach will solve problems across platforms, not only in web.
  • CIJ combines this concept with inline style paradigm of putting all the CSS rules along with their logic right into javascript file.
  • When Glen tells us that the critical CSS issue is magically solved by CIJ, I start thinking that this specific problem is only a small piece of the huge puzzle called web performance.
  • Of course, CIJ could be a substitution for CSS on non-web platforms, but it underlines mainly the problem of these specific systems.

Disclaimer: This article is very opinionated. Please use whatever you want. I highly advise you to employ different techniques for different applications, so you can compare them on real use cases…

ReactJS Authentication Tutorial, Part 2

ReactJS Authentication Tutorial, Part 2  #web_dev #front_end #cli #reactjs #Programming

  • The component is pulling data from an API, so it needs a way of holding that data.
  • In the constructor, we define the initial state as seen in the code below:

    In the method, we call the method we exported from the helper file and set state as seen below:

    Now, we took advantage of one of the ReactJS lifecycle hooks, .

  • So, we invoked the method in the hook as seen below:

    All we are trying to do is tell ReactJS to load the data from the API immediately when the component gets rendered.

  • Finally, we rendered the component with the ReactJS method.
  • This renders the root component in the div, which is the starting point of our ReactJS application.

We continue our series on creating an authenticated ReactJS application by looking at how to setup our front-end with the help of Facebook’s CLI tool.

Introducing the new React Nanodegree Program from Udacity

  • With the technology generating so much excitement, and so much opportunity emerging in the field, the timing is perfect to introduce Udacity’s newest offering: the React Nanodegree program!
  • If it seems unusual that Udacity should partner with a training organization to launch a Nanodegree program, React Training’s Tyler McGinnis has a succinct answer for why the union makes perfect sense:

    “React Training is really good at teaching React, and Udacity is really good at supporting students.”

  • When Tyler McGinnis highlights our ability to support students on their learning journeys, he is referring to features that are central to the Udacity learning experience, and which figure prominently in the structure of this new program, such as:

    Mentorship: Every enrolled student of the React Nanodegree program will have access to mentors in the Udacity classroom.

  • The unique partnership between React Training and Udacity offers students an opportunity that simply can’t be had elsewhere—the chance to learn React from the team that trains the world’s most successful companies, in a learning program focused on creating career opportunities for its students.
  • The new React Nanodegree program is one of the most efficient, economical, and effective ways to master the skills and gain the experience necessary to become a professional React developer.

Master the skills and gain the experience necessary to become a professional React developer with Udacity’s new React Nanodegree program. Enroll today!

Optimizing React Rendering (Part 1) – Flexport Engineering

Optimizing React Rendering (Part 1)  #Reactjs #Javascript #Webdev

  • PureComponent does a shallow object comparison on the props, and since you are passing in the same object reference, shouldComponentUpdate will return false and the updated data will not be rendered.This means that if any part of your app mutates data that needs to be rendered, PureComponent puts you at risk of displaying stale data.
  • This is by far the biggest blocker because it results in incorrect UI behavior, and it is outside the control of your component.Fix: Never mutate values used as React props or state.
  • Even if some ancestor component triggers a re-render, PureParent will not re-render because neither its state or props has changed.This gotcha also leads to incorrect UI behavior, but the issue is scoped to the component itself, making it easy to fix.Fix: Extract data dependency into state or props, and update state or props when the data changes.Object copyingQ: What happens when Parent is re-rendered with an unchanged props.dataList?A: PureChild is re-rendered wastefully because filter returns a new object, which tricks PureChild into thinking that the prop has changed.This problem is triggered by calling any function that creates a new object or using an inline object literal in render.Fix: Cache your derived data calculations.
  • A: PureChild is re-rendered wastefully because arrow functions and Function.prototype.bind return new function instances, which tricks PureChild into thinking that the onClick handler has changed.Fix: Don’t use arrow functions and bind in render.
  • When those props change, PureChild will re-render wastefully.Fix: Unless you’re writing some sort of higher-order-component, don’t be lazy and be explicit about the props that you are passing.ConclusionTurns out our app is littered with every single one of these gotchas, and is especially dependent on mutation side-effects.

We migrated our web app to React almost 3 years ago, and since React performs extremely well out of the box, optimizing performance was not something we had to worry about. However, as our…
