Standardize auth logic across all Topcoder frontend apps.

This repo contains several pieces:

1. The accounts app itself, as deployed at accounts.topcoder.com
2. The connector mini-app, as deployed at accounts.topcoder.com/connector.html
3. An npm module exposing:

• The connector-wrapper module that provides
• A library of shared auth functionality (token handling, etc)

> npm install --save tc-accounts

The connector exports a configureConnector method that must be invoked before any of the other methods, which likely means the entry of your app, or the entry of your auth logic. This will create and attach the connector iFrame to the DOM in your app.

import { configureConnector } from 'tc-accounts'

configureConnector({
  connectorUrl: 'https://accounts.topcoder.com/connector.html',
  frameId: 'tc-accounts-iframe'
})

import { getFreshToken } from 'tc-accounts'

getFreshToken().then( token => {
  console.log(token)
})

• getFreshToken() - Returns a promise for a token. Under the hood it will take care of refreshing your token as needed. Works perfectly with angular-jwt

const config = function($httpProvider, jwtInterceptorProvider) {
  function jwtInterceptor() {
    return getFreshToken()
  }

  jwtInterceptorProvider.tokenGetter = jwtInterceptor

  $httpProvider.interceptors.push('jwtInterceptor')
}

• logout() - Log out of all Topcoder apps. Returns a Promise.
• isTokenExpired(token, offsetSeconds = 0) - Returns whether or not a given JWT is expired. Accepts an offset in seconds.
• decodeToken(token) - Returns the contents of a JWT as a javascript object

If you only need to work on the app itself, getting up and running is super simple.

> npm install
> npm run dev

• Browse to localhost:3100

If you need to test your integration locally, you'll need a few more steps. The iframe technique we are using here does not play well with webpack-dev-server, and we need to serve two apps from the same subdomain (port, in this case).

> npm install
> npm run build:dev
> npm run build:connector

• Ensure that you have an alias for local.topcoder-dev.com to 127.0.0.1 in your hosts file
• Serve the dist directory on port 8000. We suggest python -m SimpleHTTPServer if you're on OS X.
• Point whatever app you're trying to integrate locally to http://local.topcoder-dev.com:8000 to develop.
• You should now be able to browse to http://local.topcoder-dev.com:8000 to see your local version of the accounts app

You'll need to rerun the build:dev and build:connector commands manually to see your updates.
