If you have no previous experience and your only education is a boot-camp, then I would recommend getting some projects up on github. If you have nothing then just make up some stuff for fun. I generally won't hire somebody if they have no code to show me.
Good luck!
Cheers!
That being said, bootcamp has gone a few rounds now, and many companys' junior positions have been filled by previous graduates. so the demand(for entry level) may have gone down.
