Advanced State Management Sprint Challenge

Read these instructions carefully. Understand exactly what is expected before starting this Sprint Challenge.

This challenge allows you to practice the concepts and techniques learned over the past sprint and apply them in a concrete project. This sprint explored advanced state management. During this sprint, you studied the reducer pattern, redux, and context APIs. In your challenge this week, you will demonstrate your mastery of these skills by creating Smurfs village!

This is an individual assessment. All work must be your own. Your challenge score is a measure of your ability to work independently using the material covered through this sprint. You need to demonstrate proficiency in the concepts and objectives introduced and practiced in preceding days.

You are not allowed to collaborate during the sprint challenge. However, you are encouraged to follow the twenty-minute rule and seek support from your TL if you need direction.

You have three hours to complete this challenge. Plan your time accordingly.

Introduction

In this challenge, you are to build a Smurfs village utilizing context or Redux as your state management. Build this challenge from the ground up using what you have learned about state management.

Commits

Commit your code regularly and meaningfully. This helps both you (in case you ever need to return to old code for any number of reasons) and your team lead as the evaluate your solution.

Interview Questions

Be prepared to demonstrate your understanding of this week's concepts by answering questions on the following topics. You might prepare by writing down your own answers before hand.

What problem does the context API help solve?
In your own words, describe actions, reducers and the store and their role in Redux. What does each piece do? Why is the store known as a 'single source of truth' in a redux application?
What is the difference between Application state and Component state? When would be a good time to use one over the other?
Describe redux-thunk, what does it allow us to do? How does it change our action-creators?
What is your favorite state management system you've learned and this sprint? Please explain why!

You are expected to be able to answer questions in these areas. Your responses contribute to your Sprint Challenge grade.

Instructions

Task 1: Project Set Up

This section should include instruction for the sprint challenge. These should only cover things that are not being evaluated by the challenge itself, e.g. environment/project setup, link to a starter project, etc. In general, this will be the following Git fork, clone, branch, commit, push, create pull request flow, though may need to be adapted for some specific challenges.

[ ] fork & clone this repository.

cd into the forked copy of this repository.
RUN npm install to retrieve all server-side the dependencies.
RUN npm start to get your API up and running on http://localhost:3333. This is the URL you're going to need to use within your React app in order to make AJAX requests for data.
After your API is up and running, you can open chrome and type in http://localhost:3333/smurfs. You should see an array with one smurf in it returned to you. This is an array that your API will be using to store our Smurf Data.
LOOK at your smurfs directory and notice it's just a plain ol' React App that we've built using create-react-app.
Open src/index.js to make sure that your app is ready to roll with the proper middleware.
cd into smurfs and run npm install to retrieve the client side dependencies.
RUN npm start to fire up your React application. There ought to be a pretty little message awaiting you welcoming you to the app. Follow the prompting.

LOOK at all the files you've been given for this project. One important file to note is server.js. This file contains an API that you are going to be interfacing with. Below is documentation on how to interact with the API.

Task 2: Project Requirements

Your finished project must include all of the following requirements:

Plan and implement how you are going to manage your state for your application
You must use either context or Redux as your state management system
Once you have planned out your state management system, fetch data from the smurf server and display the data it returns
Add a form to collect info for a new smurf, and make a POST request to the server to add a new smurf to your village

In your solution, it is essential that you follow best practices and produce clean and professional results. You will be scored on your adherence to proper code style and good organization. Schedule time to review, refine, and assess your work and perform basic professional polishing including spell-checking and grammar-checking on your work. It is better to submit a challenge that meets MVP than one that attempts too much and does not.

Resource: API documentation

GET '/smurfs'

Retrieve an array all the Smurfs in the Smurf DB by writing a GET to the endpoint /smurfs.
Double check that your response from the server is an array of smurfs.

[
  {
    name: "Brainey",
    age: 200,
    height: "5cm",
    id: 0
  }
];

POST '/smurfs'

Design the functionality to add a smurf to the Smurf DB you'll need all three fields. name, age, and height.

Example of the shape of data to be sent to the POST endpoint:

{
  name: 'Brainey',
  age: 200,
  height: '5cm'
}

Double check to make sure that a smurf is created correctly once your functionality is built out.

Initially Brainey will be in the array, but it takes more than one smurf to make the village. Be sure to add a few smurfs to populate our smurf village.

HINT if you are going to be working on Stretch Problem, you'll need to use that unique id.

Example of object created in Smurf DB:

[
  {
    name: "Brainey",
    age: 200,
    height: "5cm",
    id: 0
  },
  {
    name: "Sleepy",
    age: 200,
    height: "5cm",
    id: 1
  }
];

Task 3: Stretch Goals

After finishing your required elements, you can push your work further. These goals may or may not be things you have learned in this module but they build on the material you just studied. Time allowing, stretch your limits and see if you can deliver on the following optional goals:

Build a smurf profile page with using react-router and dynamic url params
Using React Testing Library, test one or more of your components (not any component that fetches data though)

Submission format

Follow these steps for completing your project.

Submit a Pull-Request to merge Branch into master (student's Repo). Please don't merge your own pull request
Add your team lead as a reviewer on the pull-request
Your team lead will count the project as complete after receiving your pull-request
