Angular2 + JSPM cheat sheet

First time setup

  • install jspm beta: npm install -g jspm@beta
  • set up your project: jspm init
  • install dependencies: jspm install angular2 reflect-metadata zone.js es6-shim

This will create a jspm_packages folder, and a config.js file.

Open the config.js file - this file manages options for the System.js loader - tweak it as appropriate

[] + []; // JavaScript will give you "" (which makes little sense), TypeScript will error
//
// other things that are nonsensical in JavaScript
// - don't give a runtime error (making debugging hard)
// - but TypeScript will give a compile time error (making debugging unnecessary)
//
{} + []; // JS : 0, TS Error
[] + {}; // JS : "[object Object]", TS Error
{} + {}; // JS : NaN, TS Error
