Library App Hands On

In this Library App hands on, you are to write a CRUD application for displaying, creating, updating and deleting a list of books.

Each book record has the following structure:

{
  "id": <id of the record>,
   "title": <title of the book>,
   "plot":<plot of the book>
}

For this lab, we will use files to represent the database. You can see each record in the scratch directory after you run nodemon for the first time.

To access the database, you make use of the data object from the data.js module. This has already been imported in index.js. Read the documentation for the data.js module at the end of this readme file.

Questions

Create the CRUD for the library app. Add in the following features

• Display all books (one route)
• Add a new book (two routes, one to display the form, one to process the form)
• Update a book (two routes, one to display the form, one to process the form, the user should be able to select which book to update)
• Delete a book (two routes, one to display a confirmation screen, one to process the delete)
• Find a book by id (two routes, one to display the search form, one to display the details of the book)

Documentation for the data.js module

You can check the test.js file to see how to use the functions provided by the data object.

To reset, the database, delete the scratch folder.

get all books

data.getAll()

Returns an array of all the books in the database so far. Sample output:

]
