What to Read to Get Up to Speed in JavaScript

There’s been a lot of great feedback and suggestions thrown out and I wanted to offer up what I felt were goodbooks/resources to carry you through the learning process. While I list a number of books in the Big List page that I created, narrowing it down into specific levels makes a lot of sense.

Note that some resources will overlap between levels. That should be expected as some books cover a wide breadth of language features. Also, I am NOT covering blogs in this post, only books (print and online).

Intro to Vue.js: Rendering, Directives, and Events

Intro to Vue.js: Rendering, Directives, and Events | JavaScript for Line of Business Applications | Scoop.it
If I was going to sum up my experiences with Vue in a sentence, I’d probably say something like "it's just so reasonable" or "It gives me the tools I want when I want them, and never gets in my way". Again and again when learning Vue, I smiled to myself. It just made sense, elegantly. This is my own introductory take on Vue. It's the article I wish I had when I was first learning Vue. If you'd like a more non-partisan approach, please visit Vue's very well thought out and easy to follow Guide.

Getting Started with Node, Express and Postgres Using Sequelize

Getting Started with Node, Express and Postgres Using Sequelize | JavaScript for Line of Business Applications | Scoop.it

We're going to be using PostgreSQL and Sequelize as the ORM of choice to write a minimalistic Todo list application.

By the end of this tutorial, we will have created an API for a todo list application that will enable us to create multiple todos, add list items to those todos, update the list items and delete them. By working through an application in which we implement functionality to add things, update and delete them from a database, this tutorial will serve as an introduction to writing more advanced CRUD applications.

Front-end Developer Handbook 2017

Front-end Developer Handbook 2017 | JavaScript for Line of Business Applications | Scoop.it

This is a guide that anyone could use to learn about the practice of front-end development. It broadly outlines and discusses the practice of front-end engineering: how to learn it and what tools are used when practicing it in 2017.

It is specifically written with the intention of being a professional resource for potential and currently practicing front-end developers to equip themselves with learning materials and development tools. Secondarily, it can be used by managers, CTOs, instructors, and head hunters to gain insights into the practice of front-end development.

The content of the handbook favors web technologies (HTML, CSS, DOM, and JavaScript) and those solutions that are directly built on top of these open technologies. The materials referenced and discussed in the book are either best in class or the current offering to a problem.

The book should not be considered a comprehensive outline of all resources available to a front-end developer. The value of the book is tied up in a terse, focused, and timely curation of just enough categorical information so as not to overwhelm anyone on any one particular subject matter.

Making your Angular apps fast

Making your Angular apps fast | JavaScript for Line of Business Applications | Scoop.it

Angular claims to be very fast by default. What does “fast” really mean? Of course, this always depends on the context. What does our application do? How many different things is it doing at a certain point? How is our application’s component tree structured and how many bindings does it introduce? This and other questions come into play when trying to figure out, how we can make our applications faster.

A couple of weeks ago we were discussing a demo application in which we compared the default performance and what we can do to make it faster. In this article we’d like to take this demo and show some tips and tricks to make it blazingly fast. One or the other trick might help speeding up your application as well.

A deep dive on Angular decorators

Decorators are a core concept when developing with Angular 2 and above. There’s also an official TC39 proposal, currently at Stage-2, so expect decorators to become a core language feature soon in JavaScript as well.

Back to Angular, the internal codebase uses decorators extensively and in this post we’re going to look at the different types of decorators, the code they compile to and how they work.

Redux: Structure your frontend applications

Redux: Structure your frontend applications | JavaScript for Line of Business Applications | Scoop.it

avascript ecosystem is really rich: full of developers but also full of frameworks and libraries.

When you want to develop a frontend application, whatever its rendering framework, you will have to structure things into your project in order to organize the data management with views. This case occurs particularly when you use component rendering frameworks like React or VueJS.

Historically, this has been needed by React so that’s why Facebook has open sourced its tool named Flux.

Why Ember.js?

  • Convention over configuration. It reduces the configuration related codes like anything.
  • Much better data change observing mechanism than angular.js like frameworks.
  • A priority based run loop, who decides which task to run first.
  • Built in architecture (with ember cli) has its own advantages. Easier to shuffle developers across teams.
  • ES6 syntaxes. Modern technology.
  • Huge community. Ember even has npm like emberobserver.
