This challenge allows you to practice the concepts and techniques learned over the past week and apply them in a concrete project. This Sprint explored Authentication. During this Sprint, you studied Introduction to Authentication, Using Sessions and Cookies, Using JSON Web Tokens (JWT), and Client-side Authentication. In your challenge this week, you will demonstrate proficiency by creating an application that will give you a list of random dad jokes, as long as you are authorized.

• DISCLAIMER Authentication is a subject that many people spend a large amount time throughout their careers obtaining knowledge over. This is not something we expect you to have a mastery over, rather, we're preparing you to be able have an intelligent conversation about the subject.

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

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 PM and Instructor in your cohort help channel on Slack. Your work reflects your proficiency w/ Authentication and your command of the concepts and techniques in the Introduction to Authentication, Using Sessions and Cookies, Using JSON Web Tokens (JWT), and Client-side Authentication modules.

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

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 project manager.

In this challenge, you build a real wise-guy application. Dad jokes are all the rage these days. Currently the application is trying to receive some Dad Jokes, however we are currently locked out.

Implement an User Authentication System in order to access the jokes from the Jokes API that we want to consume. You will need to ensure that your system uses bcrypt for hashing and encrypting your user's passwords, as well as JWT for handling the authorization aspect of the app.

Demonstrate your understanding of this week's concepts by answering the following free-form questions. Edit this document to include your answers after each question. Make sure to leave a blank line above and below your answer so it is clear and easy to read by your project manager.

1. What is the purpose of using sessions?
2. What does bcrypt do to help us store passwords in a secure manner.
3. What does bcrypt do to slow down attackers?
4. What are the three parts of the JSON Web Token?

Follow these steps to set up and work on your project:

• Create a forked copy of this project.
• Add PM as collaborator on Github.
• Clone your OWN version of Repo (Not Lambda's by mistake!).
• Create a new Branch on the clone: git checkout -b <firstName-lastName>.
• Implement the project on this Branch, committing changes regularly.
• Push commits: git push origin <firstName-lastName>.

Follow these steps for completing your project:

• cd into the root of the project and run yarn to install dependencies.
• Once you have your node_modules go ahead and run yarn server or npm run server to start your node server.
• Submit a Pull-Request to merge Branch into master (student's Repo).
• Add your Project Manager as a Reviewer on the Pull-request
• PM then will count the HW as done by merging the branch back into master.

Helpful Tip on Testing this Project:

• TEST this project using POSTMAN.

• Implement the register function inside /config/routes.js.
• Implement the login function inside /config/routes.js.
• Use JSON Web Tokens for authentication.

Note The migrations and a database with empty users is already included

• Add the authentication related code. If everything is done correctly, visiting /api/jokes should return a list of jokes.

• Add a React client that connects to your API and has pages for Sign Up, Sign In and showing a list of Jokes.
• Once you have the functionality down, style it!
