Settings up mutliple app targets in React-Native

1. yarn add react-native-config
2. react-native link react-native-config
3. Create .env files for each configuration. Ex: .env.dev, .env.prod, etc Ex:

API_ENDPOINT=https://api.myresource.com/dev
ENV=dev

4. Follow instructions for set up with react-native-config and extra steps

Intro

If you ever need a mobile application, you probably have an API endpoint to talk to. And if you're doing it right, you should have different environment for your API, usually it'll be: dev, staging, production.

The problem: How do we do the testing for our app?

We dont' want to perform test againts the production API. We need a way to teach our app to talk to different API environment. But what is the switch?

The naive way:

# Assumes htpass authentication

registry_server='docker.mycloud.com'
username='bob'

# List all images (i.e. repositories)
curl -k -X GET "https://$registry_server/v2/_catalog" -u $username -H "Accept: application/json"
Enter host password for user 'bob':
{"repositories":["app-base","ubuntu","cache-base"]}

/**
 * Fancy ID generator that creates 20-character string identifiers with the following properties:
 *
 * 1. They're based on timestamp so that they sort *after* any existing ids.
 * 2. They contain 72-bits of random data after the timestamp so that IDs won't collide with other clients' IDs.
 * 3. They sort *lexicographically* (so the timestamp is converted to characters that will sort properly).
 * 4. They're monotonically increasing.  Even if you generate more than one in the same timestamp, the
 *    latter ones will sort after the former ones.  We do this by using the previous random bits
 *    but "incrementing" them by 1 (only in the case of a timestamp collision).
