MapTo function is provided by the AEM SPA Editor JS SDK (@adobe/aem-react-editable-components). The AEM component path /apps/jorvee/components/text represents the sling:resourceType of the AEM component. This path gets matched with the :type exposed by the JSON model observed earlier. MapTo takes care of parsing the JSON model response and passing the correct values as props to the SPA component.
MapTo('jorvee/components/text')(Text, TextEditConfig);
Above MapTo function will map your AEM Text component with SPA Text component. The complete line will be like this with export keyword.
export default MapTo('wknd-spa-react/components/text')(Text, TextEditConfig);
