In an earlier video we took a look at Rack to build incredibly lightweight web applications with Ruby. Rack's toolkit allowed us to quickly throw to get a working application, but we did have to put a little effort into it once we wanted to build something a little more complex.

Sometimes you want a fast and simple framework for building a simple web application. Perhaps you only need to respond to a handful of routes, or you want the response time for a small part of a bigger application to be lighting fast. The Sinatra framework is made for just these moments.

Today let's take a quick look at this framework and see how quickly we can build lightweight web applications.

To get started we first need to install the Sinatra gem:

gem install sinatra

One Paragraph of project description goes here

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.

Prerequisites

System Design Cheatsheet

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

Basic Steps

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?

GraphQL Cheat Sheet

Overview

An alternative approach to RESTful APIs
Clients issue queries/mutations to read and update data
Clients can fetch only the entity fields that are required
GraphQL query syntax can express complex entity relations => nested objects
Mitigates the explosion of RESTful endpoints in scenarios where many different representations of an entity are needed
Graphiql is a query execution UI, also provides good documentation

Set-up github repo for project

-Create a separate repository in github

-Does your project have a package.json yet? If not, create one within your project directory:

$ npm init -y

-Create a .git directory in your project directory:
