JQuery vs React vs Angular

Frontend

Málaga

Hello. I’m Rafa

Rafael David Latorre López - Villalta

• Lead Frontend & UX Chief at Tolq.com • resetsociety.com founder

9 years of experience developing experiences which try to be easy for the user

Today we are going to be talking about movies

Is that true?

Nope

Lets give a closer look to them

JQuery (or zepto)

• It’s just a library

• It allows us to access and change the DOM easily

• Unifies cross-browser inconsistent functionalities

• It is really easy to do interaction design with it

JQuery vs Vainilla JS

vs

Sample app

.element .toggle

.details.hidden

Easiest and most common way:

• Backend with templating system renders everything (php, .net, rails, etc)

• Jquery just toggles a class to hide and show the extra content

• No Javascript rendering

• No AJAX

Easiest and most common way:

What if I want to render with JS ?

Rendering markup with JS

Rendering markup with JS

if the markup is complex you should use

http://handlebarsjs.com/

Loading from the server

Pagination: better in the server

Pagination: better in the server

• The code begins to become more unreadable

• Organising the code is not easy.

Is then Jquery a bad choice for dynamic apps?

Nope

This was created with Jquery

The code

Angular• It’s a complete framework

with:

• Data-binding, basic templating directives, form validation, routing, deep-linking, reusable components and dependency injection.

• Getting started is easy, mastering it is quite difficult.

• Double data binding

• Low Decision Fatigue

Angular is BIG

Sample app

Easiest and most common way:

• Render full Angular template from the backend

• Everything is rendered via Javascript

• Doing AJAX is easy and advisable

The view template

The controller

Paginating with AJAX

Refactoring

Refactoringindex.html

Composing

personDetails.html

index.html

person-details.js

a piece of hell

Angular 2 is coming

• In no more than a few months the beta will be stable

• Breaking changes everywhere

• Copies several good practices from React

React• It’s just a library to render views

and give them more functionality with JS.

• It includes a Virtual DOM

• Simple to use and learn

• Can be rendered in the Server (Isomorphic JS)

• Unidirectional data flow

• Can create native mobile functionalities with React Native

Sample app

Easiest and most common way:

• Initialise a div with JSON props where React components will be rendered

• Everything is rendered via JSX + Javascript

• Doing AJAX is easy and advisable

Normally you start with this:

But quickly turns into this:

Composing

Paginating with AJAX:

{page}

Recap

Pros

ReactAngularJQuery• Low entry barrier

• Trivial to set up anywhere

• Easier and simpler on basic DOM interactions

• Extremely popular

• It provides a big set of tools to deal with everything in the frontend

• Low decision fatigue

• Currently popular, plenty of apps that will need maintenance

• It’s easy to learn and master

• Fastest rendering

• Opens mobile development for frontend developers

• Isomorphic JS

Cons

ReactAngularJQuery• Rendering

markup is not elegant

• Requires very strict development strategies on complex products

• Mastering it is really hard

• It has unnecessarily complex features (some of which will disappear in 2.0)

• It’s going to be outdated in the coming months

• Restrictive in some cases

• Difficult to set up properly

• Decision fatigue

• Difficult to set up properly

When should you use them?

JQuery if:

• There is no need to render a lot of templates

• You are starting out

• You are doing mostly DOM & CSS manipulation

• You need the extra functionality it comes with ($.get, $.map, $.each)

Angular if:

• You are an experienced programmer

• You already have experience with it

• You want one tool that deals with everything

• You framework allows it

React if:

• You need fast rendering

• You are a beginner/intermediate programmer

• Your framework needs some flexibility
