This is a Single Page App (SPA) using a Web Component Library I created. It uses data from a Geographic Database to countries, regions, cities, in the World.<p>If you’re not familiar with Web Components here is a good overview article from Mozilla on how to use them:<p><a href="https://developer.mozilla.org/en-US/docs/Web/Web_Components" rel="nofollow">https://developer.mozilla.org/en-US/docs/Web/Web_Components</a><p>Basically it allows for creating custom HTML elements from JavaScript. In this case I developed components that allow for viewing of data from JSON web services and binding to other components on screen.<p>Here is the GitHub Source:<p><a href="https://github.com/dataformsjs/dataformsjs/blob/master/examples/places-demo-web.htm" rel="nofollow">https://github.com/dataformsjs/dataformsjs/blob/master/examp...</a><p>For comparison the main page has links to React, Vue and other versions of the same app as I developed similar React Components and standard JavaScript.<p><a href="https://www.dataformsjs.com/" rel="nofollow">https://www.dataformsjs.com/</a>
