I deployed a react app with the server being hosted on Heroku, and the backend/Heroku keeps on crashing after a few page loads or messages I send on the app. To clarify, the app works initially with no signs of impending error, and then...crash. I made numerous changes to my code to try and find the problem. Nothing. Thanks in advance for any help.
createPool
Just in case this helps anyone in the future...I set up mySQL DB using createConnection instead of createPool. If I am not mistaken, pool dynamically creates connections so that the server does not crash when lots of users connect to it.
