System Design Cheatsheet

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

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?

DevCamper Backend API Specifications

Create the backend for a bootcamp directory website. The frontend/UI will be created by another team (future course). The html/css template has been created and can be used as a reference for functionality. All of the functionality below needs to be fully implmented in this project.

Bootcamps

List all bootcamps in the database
- Pagination
- Select specific fields in result
- Limit number of results

Filter by fields

	### Javascript
	var requestOptions = {
	method: 'GET',
	redirect: 'follow'
	};

	fetch("https://jsonmock.hackerrank.com/api/movies?Year=1999", requestOptions)
	.then(response => response.text())
	.then(result => console.log(result))
	.catch(error => console.log('error', error));

	// Enable component-scanning and auto-configuration with @SpringBootApplication Annotation
	// It combines @Configuration + @ComponentScan + @EnableAutoConfiguration
	@SpringBootApplication
	public class FooApplication {
	public static void main(String[] args) {
	// Bootstrap the application
	SpringApplication.run(FooApplication.class, args);
	}
	}

	1. merge error/commit merge error

	1. i -> enter comment -> esc -> :wq -> enter



	1. Deploy a static site in github

	repo -> setting -> GitHub Pages -> select the branch -> code will deploy at <yourusername>.github.io/<yourrepo>

	import UIKit

	//var and const
	var str = "Hello, playground, since"
	str = "some";
	let cons = "hello"

	//datatype
	var a:Int = 2
	var b = 5
