How to call file header/footer in Ionic?

Hi, everyone. I am beginner of Ionic and have question on how do I call/import files from the same folder?
The thing is I am trying to do header and footer for the application. So, both header and footer will be repeatedly used for all the pages. Thus I think it will easier if I just put the header in 1 Page and just call it in homepage. But the problem is I did not know how to. I do know how to call in php, it use <?php include 'fileName.php';?> . Can anyone help? Thank you!!!
