Plain JS Enumeration App

An example of a plain JavaScript front-end web app with enumeration attributes.

This app, which is accompanied by a tutorial, is the 3rd example app of our incremental sequence of six examples of Plain JS Front-End Web Apps. This app supports the following operations:

  • Create a new book record
  • Retrieve and list all book records
  • Update a book record
  • Delete a book record
    •

    • For playing with the app, you may first want to and then view it with Retrieve and list all books. For observing the internal status and error messages, turn on the JavaScript console.

    This JavaScript front-end data management app takes care of only one object type ("books") for which it supports the four standard data management operations (Create/Retrieve/Update/Delete). It extends the validation app (described in Part 2 of our tutorial) by adding enumeration attributes, but it needs to be extended by adding further important parts of the app's overall functionality.
