Aircraft
During flight from ZZZ to ZZZ1; [the] Captain's windshield shattered. There was an initial flash at the base of the windshield and caused the glass to crack. A few minutes later the entire windshield was shattered. The aircraft did not lose cabin pressure and no glass broke off. The Captain donned their oxygen mask and then I put mine on as well. I was Pilot Flying and slowed the aircraft to 200 kts. I confirmed with the Captain and [requested priority handling] with Air Traffic Control and diverted to ZZZ2. This decision was easy to make because [recent flight training] was a flight [from] ZZZ1 to ZZZ with an incident that causes you to divert to ZZZ2. The flight ended in ZZZ2 and we did a plane swap and finished our flight to ZZZ1.Landing the plane with an oxygen mask on was a first for me because in prior training; we normally take them off once the aircraft is below 10;000 MSL. The site picture is definitely different when landing. Days later; during the trip; I learned that there was an emergency and abnormal procedures for a shattered windshield. I'm used to a warning or caution light triggering me to refer to the E&A checklist. I recommend studying at least the table of contents to know what is in the E&A checklist.
