Can I spray foam insulate from the outside?

I bought an old timer home on Gibsons, BC and the siding needs replacing. I want to use the opportunity to seal up and insulate the wall cavity once exposed. I expect to see insufficient or no insulation. After applying spray foam what is best to apply (tyvek vs. something other) before installing the new board and batton siding?

Thank you, Kurt

Exterior walls need greater protection because they are exposed to the outdoor elements. It is advised homeowners choose closed-cell high-density foam for exterior walls. Not only does it keep air and moisture out, but it also makes the exterior walls more structurally sound, adding strength to a home and making it more durable. Insulation in the exterior walls is more prone to becoming damaged, which is why it must offer superior strength and durability. High-density foam is ideal for exterior walls. Besides the added strength and protection it brings, there are other ahrefs= https //www.windsorsprayfoam.com/interior-and-exterior-walls.html benefits
