You will just have to copy the code given here and paste it into the appropriate files as directed. You will be given the code for the files to be included in the function and client components in this tutorial. We will use the Catalyst web console and the Catalyst Command Line Interface (CLI) to build this application. You can access a working application of each type and test their functioning here: ZCQL: To fetch data from the Data Store through querying.Data Store: To store the to-do list items in a table.The to-do list application uses the following Catalyst features: We will be using the native plugins offered by Catalyst to easily build, test, and deploy Angular and React apps.
