Anyone no how to fit a driver’s side door handle?
If you mean the outer handle you`ll need to take the door card off inside and do it from that side i think
Not done a primera but some of the ones I’ve had to do, It’s easier to change the bloody car, 
good luck with it.
Probably much easier than changing a headlight bulb on some modern cars.
As was said, firstly remove the door trim card. Probably retained by several philips head screws (hidden behind plastic plugs?) & umpteen spring clips. Then carefully remove or cut the plastic liner. (gaffa tape it up after).
With a light you should then be able to see the screws or small bolts that retain the handle. One will probably be directly accessable, the other might have an access hole in the inner door skin. You may need a 1/4" drive socket set.
Once the handle is released (or before possibly?) there will then be probably one or two linkage rods to disengage. These are often held in place with a spring clip, or if in a dog leg & no clip, the clip will be found & need to be disconnected at the other end of the rod.
This guidance is not vehicle specific & things may well have changed since I gave up doing car repairs 10 years ago.
… and, as a thought just before hitting submit, maybe this might help:

Edit: Just looked at the 1st vid by Esurname. He mentions the window track is blocking access to one of the retaining bolts and then goes on to take the door into 100 pieces.
If he had found the bottom window track retaining bolt & removed it, it is highly likely the track would then just have swung out of the way.
