Continued part 2 of earlier video at https://www.spjeff.com/2017/05/31/angular-cli-todo-list-in-sharepoint-content-editor/

Here we add “spcrud.ts” library with CRUD methods to save JSON data over REST api into SharePoint Lists.
SPCRUD is a Typescript library with methods to easily interact with SharePoint APIs by providing management of Digest Token, HTTP headers, and URL formatting. As developers we interact with simple TypeScript methods that have input validation which in turn execute the correct underlying HTTP call.

Cheers!
