First off, I'm really, really sorry if this has been asked before, but I did not find a satisfying answer. This step seems missing / unthreatened in literally all explanations and tutorials out there.
I've read literally everything about making a Shopify App and I've built one and it works. I'm in the stage of submitting it, but I discovered the project directory is about 40k+ files large. When debugging the App, I ran the test server over ngrok over my local laptop, but it's kind of self explaining that I won't keep it running there 24/7 for the next 50 years.
After reading all guides, I still lack in one important information. How is my app being pushed/pulled/deployed to their server? What exactly do I do to achieve this, and furthermore, how do I update bugfixes afterwards?
I am aware there is a review process and everything, the question is, when and how does my local app version move over to their servers. exactly?
I was really not able to find satisfying answers to this.
Help greatly appreciated.
