In this capstone project, you will build all of the routing and database logic for an internal tool for a comic book publishing company called X-Press Publishing.

The X-Press Publishing internal tool should allow users to:

• Create, view, and update artists
• Create, view, update, and delete comic book series
• Create, view, update, and delete issues of a specific comic book series

You can view all of this functionality in action in the video below:

To start, download the starting code for this project here. After downloading the zip folder, double click it to uncompress it and access the contents of this project.

To view your local version of the site, open index.html in Google Chrome.

To complete this project, you will need to create the database tables and API routes specified below. In addition to these specs, we have provided high-level steps for additional guidance in tying together all of your new skills in this project, linked at the end of this article. Feel free to not use these steps if you'd like an extra challenge. As you work through the project, be sure to use npm to install the necessary packages such as express.

To test this functionality you can run the testing suite and interact with the API via the provided front-end. If you want more data to interact with in the front-end, you can run the seed.js file to add data to your database.

We've provided an empty migration.js file for you to write table creation logic in.

In order for the tests and provided front-end to run properly, you will need to make sure to:

• Create and export your Express app from a root-level file called server.js
• Accept and set an optional port argument for your server to listen on from process.env.PORT
• If process.env.PORT is not set, server should run on port 4000 (this is where the provided front-end will make requests to)
• Accept and set an optional database file argument from process.env.TEST_DATABASE in all Express route files that open and modify your database
• Use the root-level database.sqlite as your API's database
• Note: When loading database.sqlite in your JavaScript files, sqlite3 will always try to load database.sqlite from the root directory path, ./database.sqlite, regardless of where the current file is located. Therefore your code will always be new sqlite3.Database(process.env.TEST_DATABASE || './database.sqlite') regardless of the file you are writing in

A testing suite has been provided for you, checking for all essential functionality and edge cases.

To run these tests, first, open the root project directory in your terminal. Then run npm install to install all necessary testing dependencies (if you haven't already). Finally, run npm test. You will see a list of tests that ran with information about whether or not each test passed. After this list, you will see more specific output about why each failing test failed.

As you implement functionality, run the tests to ensure you are creating correctly named variables and functions that return the proper values. The tests will additionally help you identify edge cases that you may not have anticipated when first writing the application.
