LED driver/transformer - inside or outside junction box?

I've made a light fixture I'm selling online which includes a 6-light puck light system which includes the 120v->12V LED driver/transformer. Would there be issues if I left the driver outside the junction box and fed the 120V wires into a junction box where it would be connected to the AC power? Would the person buying this run into issues during installation with code?

Unless you have your fixture UL certified the install will run into issues.

It is fine to leave in the wall or ceiling if the driver you use is designed to be hardwired to NM cable as pictured.
Sheathing of NM cable should be under the strain relief (clamp).

However, I don't think your driver is designed for such installation. It looks like it was designed to have a lamp cord on AC input side.

Even if it can be direct wires I would install it someplace that it can be accessed later. It may have to be serviced (replaced) at a later date.

Yeah. It has to be accessible. I was referring to to ceiling or wall behind the light.
