Ask HN: How to handle a record during an interview?

I have a record, I was convicted of a handful of felonies roughly five years ago and ended up going to prison. I have since then gotten an awesome job and am doing well. On a whim I put a few application in to some dream jobs (I reverse commute at the moment and would like to get closer to the city) and a few companies are actually very interested. I even have an interview coming up in a few days for full-stack React development. Do I disclose up front? Any input from people who do the hiring would be greatly appreciated. I would hate for it to be a perfect fit and no one says anything, only for it to be a huge issue down the road. I am confident that I can get a job on the merit of my code and I do not want to shoot myself in the foot. Thanks for any input!
