Early morning departure from ZZZ Runway XXR. Cleared for takeoff direct ZZZZZ. On the takeoff roll all engine indications were normal. As I pitched up to takeoff and receiving positive rate from my First Officer I asked for gear up. As the gear was in transit we heard and felt a bang. At first we thought it was gear related then the gear was in and another bang is heard. At that point tower tells us that we have 'sparks' coming from our engine. The bangs were intermittent about every 3-5 seconds. As we analyzed the situation we knew the right side engine was the issue sign ITT (Inter-stage Turbine Temperature) was hotter then normal. Once I seen the ITT start to shoot up into the red I put the engine from TOGA to Climb and ITT some what reduced. By this time we were also reaching 3;000 ft. so I was in the process of leveling off and reducing power. At no point did we get any alerts or indications that anything was wrong other then the weird ITT indications. The bangs only happened when throttle was in TOGA position. Once level all indications were green and we quickly decided to return to ZZZ. We requested priority handling and received vectors back to ZZZ. I contacted the Flight Attendants and told them we had issues with the right engine they quickly responded with 'Yeah; we know it was really loud back here'. Asked if any smoke is present they said no. Told them were going back to ZZZ and that everything is good and normal as of now and if that changes I will let them know. Continued to land Runway XXR with no other engine indications. We told the Tower to have fuel trucks waiting just in case of a fire. Upon landing we stopped on the runway; and Tower tells us no fire is visible and I make a PA letting everyone know of the situation and that we will be returning to the gate. Fire Trucks verified no fire and followed us back to the gate. Engines were working as normal on landing and taxi as if nothing happened.
An Air Carrier pilot reported a compressor stall in the right engine while taking off.
