I remember that I’ve been saw Meteor-blaze tempalates for sale on website long time ago but I can’t find it anymore.
It was built in meteor way like the other front-end frameworks.
Is there a css / template site like that?
This is a Blaze template, but it still use BS 4. https://wrapbootstrap.com/theme/angle-bootstrap-admin-template-WB04HF123
I think the best way is buy a more modern HTML template and split it in Meteor. It is not a long work to do.
