A little while ago I started using Typescript with the Angular 1.5 app I'm working on, to help ease the migration path to Angular 2. Here's how I did it. We'll go example by example through migrating real world code living in a large, mostly non-Typescript codebase.

Let's start with a few of the basic angular building blocks, then we'll go through some of the higher level patterns we derived.

// Declare the color as RGB; SASS will treat this as hex
$green: rgb(27,224,63);
// Declare an alpha
$alpha: .5;
// Declare another color variable as a color with an alpha
$greenAlpha: rgba($green, $alpha);

body {
  /* As RGB (which SASS actually ouputs as HEX) */
  background: $green;

## Problem 
When login in, the shell prints:
```
manpath: can't set the locale; make sure $LC_* and $LANG are correct
```

## Solution
```
sudo locale-gen "en_US.UTF-8"
sudo dpkg-reconfigure locales
