Using Typescript + Angular 1.x in the Real World

Work in progress!

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.

Secure random values (in Node.js)

Not all random values are created equal - for security-related code, you need a specific kind of random value.

A summary of this article, if you don't want to read the entire thing:

  • Don't use Math.random(). There are extremely few cases where Math.random() is the right answer. Don't use it, unless you've read this entire article, and determined that it's necessary for your case.
  • Don't use crypto.getRandomBytes directly. While it's a CSPRNG, it's easy to bias the result when 'transforming' it, such that the output becomes more predictable.
  • If you want to generate random tokens or API keys: Use uuid, specifically the uuid.v4() method. Avoid node-uuid - it's not the same package, and doesn't produce reliably secure random values.
  • If you want to generate random numbers in a range: Use random-number-csprng.

You should seriously consider reading the entire article, though - it's
