There such small latches that can be screwed up to cabinets wall and door.
There two types: magnetic ones and mechanical (with a spring).
Like this (magnetic):
And this:
Magnetic ones seem to be very strong and seems don't lose strength over time. And prices are approximately the same (in general). So, why would I prefer one before the other?
The magnetic ones are simpler imho, and don’t have so much to catch a sleeve on. Also, the tongue on the mechanical one can deform over time.
Some magnetic catches have neat functions like push in release and the door opens enough to allow fingers to open the door, when closing pushing in fully closes the door, I like those more than the mechanical style. As far as life of the hardware I have remodeled 20’s & 30’s houses that had the mechanical clasps that were still functional so I think ease of installation would be easier for the magnet style as the plate can be offset and the magnet style still work.
