A320 First Officer reported landing safely after the in flight shutdown of the number 2 engine.

Narrative

I was the pilot flying. We had just begun our descent with all briefings and checklists completed. Between 30 and 29;000 feet I felt and heard a small jolt. I thought the Captain had dropped a water bottle on the floor; but I also felt almost imperceptible yaw. We immediately looked at the ECAM and saw that engine 2 had automatically reduced itself to idle; with all other parameters normal at that instant. However; this was quickly accompanied by ENG 2 Stall ECAM. The Captain immediately assigned me to continue flying duties while he completed the ECAM. Because the EGT was climbing rapidly and out of limits; we followed ECAM procedures to shut down engine 2. [Requested priority handling] and we were cleared directly to the airport. The Captain checked FM non-normals for ENG 2 Stall and reviewed notes warnings and cautions. He then notified Dispatch; completed a briefing with the flight attendants; and made a passenger PA. After a discussion with the Captain; we decided that he would be pilot flying for the landing. We were set up originally to land on runway XL; however they offered us landing on XX to expedite our arrival. We accepted this; and I verified on the landing distance non-normals table that this would be acceptable with the wind component. We were cleared directly to a fix on the ILS; which we briefed. However after arming the approach; it became clear to me that the localizer was not reliable. I loaded the RNAV XX in the box to give the Captain backup guidance; although we were visual with the runway at this time. We were cleared for a visual approach. I queried ATC if the localizer was active for XX; and they turned it on. After receiving positive identification; I reloaded the ILS and used this to backup the visual approach. After landing; we exited the runway and asked airport rescue and firefighting (ARFF) to inspect the number 2 engine for anomalies. After receiving word that nothing was out of the ordinary; the Captain made a PA to the passengers; and we taxied to the gate.
