Im doing payment gateway, after user click proceed, I send required data and getting from the back-end an base64 encode string contain html to redirect to payment gateway page.

this is what I had tried: 

base64 : PCFET0NUWVBFIGh0bWw+PGh0bWw+PGJvZHk+PGgxPk15IEZpcnN0IEhlYWRpbmc8L2gxPjxwPk15IGZpcnN0IHBhcmFncmFwaC48L3A+PC9ib2R5PjwvaHRtbD4=

after I decode in my ts file using : 

const decodeHtml = window.atob(this.base64);

I got result like this :

<!DOCTYPE html><html><body><h1>My First Heading</h1><p>My first paragraph.</p></body></html>

How I can display this html on my project, binding to html file or pointing out to new url ? based on my finding, i can use innerHtml to bind this, but I am not sure if there are better practice to doing this and got non idea how to display this encode html file, any suggestion are welcomed.

    The best practice is not to do it at all. Angular isn't made to do such things. And using `innerHTML` would still be a bad practice because you would have two doctypes. –  Oct 01 '19 at 06:39
