AudioScope demo written in Angular 2 + TypeScript
This demo is broken into stages, so you can start with a basic HTML+JS app and convert it to Angular 2+TS a step at a time.
Our starting app, written in HTML+JS.
Move to .ts files, creating a blank tsconfig.json, and adding a few casts.
Move to using classes and a few type annotations.
Stage 4 (optional)
Move to using a class hierarchy and generics.
Move to modules and compiling to AMD.
Move to using Angular 2 and rendering our first component.
Move to using Angular 2 for the whole application. We switch from a canvas to using SVG (more friendly to being declarative), and we preload the audio files to simplify switching. We also throw in a few buttons for good measure.
