I have doing many project with mongodb for the past many years, I built one product which adopt meteorjs from scratch.
Then get involved in development of many large code-base mongodb related project, most are meteorjs.
But the only one which have apply schema with mongodb is the product I built from scratch! for others, never…
I still remember the feel of the shock when I first look into the code of a online product many years ago - there are no schema, fields are added here and there all in the code, like grain of sand on the beach…
As at that time I already had the habit that I know I can found the most important truth from the schema - from the project I have did, I feel helpless suddenly to try to understand the code.
That’s the first time, then many times, I get used to it now,
Ctrl + F is the good tool,
But definetly it is a good practice to have schema, why?
- It will be the best source of truth to know what the data be, what the business be
- It forces developer to think a little more seconds even minutes before they want to add one or many fields or implement a new feature
- It provides validation before write to the database
