Nearest Location component

About

From a list of lat and long, this will use the browser geolcation API to select the nearest. It also provides a manual selection fallback and override.

Usage

This component is purely JavaScript and relies on other components to provide UI and to consume the detected region.

This is an early version, some future improvements to be considered:

• Callback to observe detected locations to be used in other components
• Allowing "or" matches for content data-vf-js-location-nearest-activation-target="locationOne, locationTwo"
• Enabling the default while we wait for geodetection
• "Saving" a user's location when using the override

JS

You should import this component in ./components/vf-component-rollup/scripts.js or your other JS process:

import { vfLocationNearest } from 'vf-location-nearest/vf-location-nearest';
// Or import directly
// import { vfLocationNearest } from '../components/raw/vf-location-nearest/vf-location-nearest.js';

// Configure an object of your locations to detect
// You should do this in your central JS (scripts.js) as appropriate
let vfLocationNearestLocations = {
  // supply a default in case of geodetect failures
  default: {
    name: "Heidelberg",
    latlon: "49.40768, 8.69079" // lat then lon
  },
  barcelona: {
    name: "Barcelona",
    latlon: "0.40768, 0.69079"
  },
  ...
  }
}
// Bootstrap location detection
vfLocationNearest(vfLocationNearestLocations);

JS Data attributes

All are optional

• data-vf-js-location-nearest-name element will receive the name of the current location
• data-vf-js-location-nearest-override-widget element will be populated with an override widget (vf-form select list)
• data-vf-js-location-nearest-activation-target="{locationId}" will receive clicks on location change. This is a simple method to activate diverse elements.
