Useful Tools for Development and UI stuff

Chrome Extensions

Now that I am a self-proclaimed web developer, I practically live in my Chrome console. Below are some tools that allow me to spend less time there:

  • WhatFont — The name says it all. This is an easy way of finding out the fonts that your favorite website is using, so that you can borrow them for your own projects.
  • Pesticide — Useful for seeing the outlines of your <div>s and modifying CSS. This was a lifesaver when I was trying to learn my way around the box-model.
  • Colorzilla — Useful for copying exact colors off of a website. This copies a color straight to your clipboard so you don’t spend forever trying to get the right RGBA combination.
  • CSS Peeper — Useful for looking at colors and assets used on a website. A good exercise, especially when starting out, is cloning out websites that you think look cool. This gives you a peek under the hood at their color scheme and allows you to see what other assets exist on their page.
  • Wappalyzer — Useful for seeing the technologies being used on a website. Ever wonder what kind of framework a website is using or what service it is hosted on? Look no further.
  • React Dev Tools — Useful for debugging your React applications. It bears mentioning that this is only useful if you are programming a React application.
  • Redux Dev Tools — Useful for debugging applications using Redux. It bears mentioning that this is only useful if you are implementing Redux in your application.
  • JSON Formatter — Useful for making JSON look cleaner in the browser. Have you ever stared an ugly JSON blob in the face, trying to figure out how deeply nested the information you want is? Well this makes it so that it only takes 2 hours instead of 3.
  • Vimeo Repeat and Speed — Useful for speeding up Vimeo videos. If you watch video tutorials like most web developers, you know how handy it is to consume them at 1.25 times the regular playback speed. There are also versions for YouTube.

VS Code Extensions

Visual Studio Code is my editor of choice.

People love their text editors, and I am no exception. However, I’m willing to bet most of these extensions work for whatever editor you are using as well. Check out my favorite extensions:

  • Auto Rename Tag — Auto rename paired HTML tags. You created a <p>tag. Now you want to change it, as well as its enclosing </p> tag to something else. Simply change one and the other will follow. Theoretically improves your productivity by a factor of 2.
  • HTML CSS Support — CSS support for HTML documents. This is useful for getting some neat syntax highlighting and code suggestions so that CSS only makes you want to quit coding a couple of times a day.
  • HTML Snippets — Useful code snippets. Another nice time saver. Pair this with Emmet and you barely ever have to type real HTML again.
  • Babel ES6/ES7 — Adds JavaScript Babel syntax coloring. If you are using Babel, this will make it much easier to differentiate what is going on in your code. This is neat if you like to play with modern features of JavaScript.
  • Bracket Pair Colorizer — Adds colors to brackets for easier block visualization. This is handy for those all-too-common bugs where you didn’t close your brackets or parentheses accurately.
  • ESLint — Integrates ESLint into Visual Studio Code. This is handy for getting hints about bugs as you are writing your code and, depending on your configuration, it can help enforce good coding style.
  • Guides — Adds extra guide lines to code. This is another visual cue to make sure that you are closing your brackets correctly. If you can’t tell, I’m a very visual person.
  • JavaScript Console Utils — Makes for easier console logging. If you are like most developers, you will find yourself logging to the console in your debugging flow (I know that we are supposed to use the debugger). This utility makes it easy to create useful console.log() statements.
  • Code Spell Checker — Spelling checker that accounts for camelCase. Another common source of bugs is fat-thumbing a variable or function name. This spell checker will look for uncommon words and is good about accounting for the way we write things in JavaScript.
  • Git Lens — Makes it easier to see when, and by whom, changes were made. This is nice for blaming the appropriate person when code gets broken, since it is absolutely never your fault.
  • Path Intellisense — File path autocompletion. This is super handy for importing things from other files. It makes navigating your file tree a breeze.
  • Prettier — Automatic code formatter. Forget about the days where you had to manually indent your code and make things human-legible. Prettier will do this for you much faster, and better, than you ever could on your own. I can’t recommend this one enough.
  • VSCode-Icons — Adds icons to the file tree. If looking at your file structure hurts your eyes, this might help. There is a helpful icon for just about any kind of file you are making which will make it easier to distinguish what you are looking at.

How about autocomplete for Angular.io imports and such for components?

Angular (not js) with Google Material via the CLI tooling

~ Warren LaFrance ~ Leave a comment

I have been playing around with Angular & the Google Material design specification coupled with Angular-CLI.

Here is my github repo (extremely basic) but to get it working there are a bunch of installs and configurations you will need to do.

  • Make sure you are running an updated version of Node and NPM
  • The official recipe guide.
  • Install the Angular Material CDK – npm install –save @angular/material @angular/cdk
  • If you want the animations of course you need to install them too – npm install –save @angular/animations

Once you have all that done…
Use Angular CLI (make sure it is updated globally) and follow this recipe guide.

Angular’s template syntax

~ Warren LaFrance ~ Leave a comment

Angular’s template syntax:

  • [property]="expression": set property of an element to the value of expression
  • (event)="statement": execute statement when event occurred
  • [(property)]="expression": create two-way binding with expression
  • [class.special]="expression": add special CSS class to element when the value of expression is truthy
  • [style.color]="expression": set color CSS property to the value of expression

If you’re not familiar with Angular’s template syntax, you should definitely read the official template syntax documentation.

Our new TECH STACK

~ Warren LaFrance ~ Leave a comment

We have been undergoing a major upgrade to our tech stack and here is what we are implementing now…  WOOT WOOT

 

stack1

žCloud Formation – A service that allows the entire stack to be built, provisioned, provisioned, and torn down demand.

žELB – A load balancer that works with autoscaling to create and destroy servers as needed by the traffic load.

žEC2 – Cloud-based virtual machines.

žEFS – A network file system that allows multiple EC2 instances to share a file system, even across availability zones.

žS3 – A Simple Storage Service designed to hold static resources, such as images and documents.

žRDS – Relational Database Services that cross availability zones, provide high availability, provide fail-over, and provide backup.

Angular2 Constructor Guards…

Right from the angular docs…

You can use this method to prevent accidental loading of a previously loaded module..

How can I tell if a module or service was previously loaded?

Some modules and its services should only be loaded once by the root AppModule. Importing the module a second time by lazy loading a module could produce errant behavior that may be difficult to detect and diagnose.

We can guard against that danger by writing a constructor that attempts to inject the module or service from the root app injector. If the injection succeeds, the class has been loaded a second time. We can throw an error or take other remedial action.

Certain Angular modules (such as BrowserModule) implements such a guard as does this Angular Module chapter sample’s CoreModule constructor.

app/core/core.module.ts
constructor (@Optional() @SkipSelf() parentModule: CoreModule) {
 if (parentModule) {
 throw new Error(
 'CoreModule is already loaded. Import it in the AppModule only');
 }
}
