Add SPFx webpart to full-width column

By default, SPFx web parts cannot added in full-width column page layouts. To do it, in the web part manifest (the *.manifest.json file next to the web part *.ts file) set the supportsFullBleed property to true.

SPFx Routing is not reflecting in browser

 Problem

I was trying to implement routing in my SharePoint Framework webpart. The webpart working fine but only the issue is the Hash url is not reflected in the browser.
