@Sean said in First module I'm developing, HTML won't render:

@s1h4d0w

iframe.setAttribute("src", this.config.url);

Anyway, your url "https://open.spotify.com" will not be opened.

Ah thank you! At least now I know what I was doing wrong, will be tinkering some more. Seems like I need to include /embed/ in the spotify url to get it to be accessible.

And thank you @sdetweil, also a handy tip!
