Making chained API Calls using @ngrx/Effects

Purpose

This recipe is useful for cooking up chained API calls as a result of a single action.

Description

In the below example, a single action called POST_REPO is dispatched and it's intention is to create a new repostiory on GitHub then update the README with new data after it is created.
For this to happen there are 4 API calls necessary to the GitHub API:

1. POST a new repostiry
2. GET the master branch of the new repository
3. GET the files on the master branch

Reading data before application startup in Angular 2

In this demonstration I will show you how to read data in Angular2 final release before application startup. You can use it to read configuration files like you do in other languages like Java, Python, Ruby, Php.

This is how the demonstration will load data:

a) It will read an env file named 'env.json'. This file indicates what is the current working environment. Options are: 'production' and 'development';

b) It will read a config JSON file based on what is found in env file. If env is "production", the file is 'config.production.json'. If env is "development", the file is 'config.development.json'.

struct StringConstants {
    static let bullet1 = "This is a small string."
    static let bullet2 = "This is more of medium string with a few more words etc."
    static let bullet3 = "Well this is certainly a longer string, with many more words than either of the previuos two strings."
}

typealias ParagraphData = (bullet: String, paragraph: String)

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

1. Clarify and agree on the scope of the system

• User cases (description of sequences of events that, taken together, lead to a system doing something useful)
  • Who is going to use it?
  • How are they going to use it?
