Heroku local persistent storage

Question

I have created a node app with local persistent storage in a .json file. It works fine running locally, but when I deploy it to heroku the persistent storage is modified, but then erased.

Answer 1

Heroku does not provide any sort of persistent storage on dynos. If you need to persist files across sessions, you must use object storage such as Amazon S3.
