angular2-webpack

A complete, yet simple, starter for Angular 2 using Webpack.

Is Angular 2 Ready Yet?

Quick start

Clone/Download the repo then edit app.ts inside /src/app/app.ts

how to install

PHANTOMJS_CDNURL=https://npm.taobao.org/dist/phantomjs npm install

Dirty Fix

After installing node_modules dependencies, You may need to manually remove require related statements in BigInt/src/BigInt.js so that webpack does not complain.

design

Using rxjs is intended. It provide a way to centralize logic. Here I present several alternatives' pros and cons.

redux style:

Flux arch's state of art

approach: view dipatches action, reducer processes action and change store, store updates view

pros:

• dead simple data flow
• reducer can be as synchronous as possible
• easier to debug

cons:

• in virtue every reducer is a hard code into application
• no higher order composition
• logic is scattered across dumb view, smart view, and reducer
• control flow is inverted (https://github.com/Swizec/react-particles-experiment)

CPS style:

aka callback based observer pattern.

approach: Every event is handled manually.

pros:

• No stroke win a trick. A chinese proverb like 'silence makes big money'
• intuitive

cos:

• state must be explicitly shared between components
• no high order composition, not even logic reuse
• concrete command couples with concrete events

To sum up, observer pattern is not scalable. Code soonly becomes unnamable chaos

reactive style:

rxjs, rxjava, rxscala, rxandroid, rxswift, rxpy, rxgo, rxwhateveryounameit

approach: event and logic is encapsulated in asynchronous stream. (yes, logic is in stream too, in the form of closure)

pros:

• very expressive and concise
• observer without inversion of control
• fine tuned scheduler control with one line of code

cons:

• unintuitive
• all operators take a hidden parameter, namely, time.
• too many operators to learn

Choose Crypto

It seems web cryptography is the ideal library, but it lacks AES256-IGE. https://medium.com/@encryb/comparing-performance-of-javascript-cryptography-libraries-42fb138116f3#.5jwcjgmem
