Narrative: We departed Runway XXR in ZZZ. The takeoff roll and initial climb out was normal. Shortly into the climb we heard a loud banging noise and felt the airplane shuttering with the noise. No messages showed up on the ECAM. Engine indications for the number one engine were showing high EGTs and surging indications. Above 1;000 feet AGL we reduced power to idle on the number one engine and the noises stopped. We requested priority with ATC and requested vectors to return to Runway XYC. We shutdown the number one engine and completed all ECAMs. I flew while the CA (Captain) looked at follow ups; notified the FAs (Flight Attendants); the company and prepared for an over weight landing. We made a safe landing on Runway XYC and came to a stop on the runway. CFR (Crash fire Rescue Equipment) inspected the aircraft and told us there was no fire smoke or flames and that the plane looked good. We exited the runway and taxied to  Gate XX and parked without further issue. We had good weather; a great experienced CA; and ATC did a great job of working us right back around for a safe landing. I think our training department gets the credit for these events being successful. Although stressful and startling; the control and safety of the aircraft was never in question thanks to the great training.


Second narrative: I was the Captain on Aircraft X from ZZZ to ZZZ1 on DATE. We had X passengers and Y crew members aboard.  Conditions in ZZZ at the time were CAVU with light and variable winds and departures were being conducted to the north. Takeoff was planned with Config 1 Flex on Runway XXR. I was the PF (Pilot Flying) and we had a normal takeoff. At approximately 2;000 ft. MSL; a loud; constant banging was heard from the left side of the aircraft resembling a jackhammer followed by strong vibrations. No ECAM or other alerts were present; and all engine parameters seemed normal. Both engines were producing normal thrust as I called for a straight out to 3;000 ft. climb with ATC. Upon global assessment; I and FO (First Officer) determined that we were experiencing possible compressor stalls on the #1 engine. I instructed him to slowly reduce to #1 engine to idle as I advanced the #2 to MCT so we could climb now to 4;000 ft. I [requested priority handling] and transferred aircraft control to FO and instructed him to coordinate with ATC for a return to landing in ZZZ Runway XYC. I then proceeded to brief the Flight Attendants on what happened and for them to plan for a precautionary landing with no evacuation in approximately twenty minutes. Next; I made a PA to the passengers stating that we an engine issue and we would be returning to ZZZ and to expect to see safety vehicles inspecting us when we landed. When I returned; FO pointed out that the oil level was 2.5 qts and dropping on the #1 engine. After a brief discussion; we both determined out an abundance of caution that the best course of action would be to shut down the #1 engine and secure it to prevent any further damage. I did this as FO was flying and started the APU. Ran all applicable checklists and did a quick landing data assessment. I assumed PF duties and landed on Runway XYC in ZZZ without incidence and stopped on the runway. After setting the parking brake; I made the PA for the passengers to remain seated. FO coordinated with CFR (Crash Fire Rescue equipment) vehicles for inspection. All clear signal was given by CFR and then I taxied under ships power to the gate in ZZZ.Compressor stall and loss of oil pressure in number one engine.


Synopsis: A319 Flight Crew reported compressor stalls and oil loss on the number one engine and elected to do an in flight shut down on the affected engine and return to the departure airport.
