How to add defer to script tag in hiccup?

Question

I would like to add a defer attribute to a script tab in hiccup.

But things like [:script {:src "main.js" :defer}] return an error, and forms like [:script {:src "main.js"} :defer] insert "defer" in the middle of the script opening and closing tags.

Does anybody know how can i get something that translate to <script src="main.js" defer></script> ?

You need to add a value for a :defer map key:

[:script {:src "main.js" :defer true}]

It should generate:

<script src="main.js" defer="true"></script>

which is equivalent to:

<script src="main.js" defer></script>

Thanks, I did not know these attributes can still be used as key/val! – xav Mar 14 '18 at 14:25

It actually generates `` which seems to be working as well. – xav Mar 14 '18 at 14:33
