Questions people ask
Do I have to do the parts in order?
Yes. Each part ends in a state the next one assumes. You can skip the reading between the steps; skipping a step produces errors that look like bugs in docs.
Is what I built production-ready?
No, and it is not trying to be. A tutorial optimises for understanding: it leaves out the error handling, the monitoring and the hardening that a real deployment needs, and says so rather than implying otherwise.
Why this approach and not another one?
Fill this in. Name the alternative readers will have heard of, and say honestly when it would be the better choice. A tutorial that pretends there is only one way loses the readers who already know there is not.
Can I use a different tool for one of the steps?
Usually yes, and the series will not help you when it breaks. Finish it once as written, then substitute — that way a failure afterwards has exactly one candidate explanation.
How do I keep what I built up to date?
Say what "up to date" means here: dependency updates, a platform that changes under you, or nothing at all. This is the question the series raises and nobody answers.
Where does this stop being a tutorial?
At the point you start making choices the tutorial did not make for you. What next is the list of those choices.
