@pie-api/pie-element-extensions v1.48.1

pie-element-extensions

This is a set of Custom Elements and ES Modules that extend the capabilties of @pie-framework/elements in the context of pie-api service. They are intended to be deployed for use in a browser with ES imports.

Initially, the Elements will include:

Cell - an element to render a user response in a small form factor that can be displayed in a table/spreadsheet cell

Response - an element to rendder more complete user response, in a larger form factor than Cell but without necessarily rendering the actual question

Future Elements:

Aggregate - display a PIE with aggreate information about a set of responses

Modules:

This lib may also export modules & functions that are not Custom Elements. e.g.: aggregateResponses([session]) - do a map reduce to get aggregate data about user responses.

Under R&D:

pie-api will support extending the capabilities of 'installed' pies with these extensions through a definition that defines the module urls for the extension's modules. See src/multiple-choice/pie.config.js
