Suppose I have a database in mongodb, in which I can store some information with .save () but now, I want to retrieve that information and pass it to the client, for which I use findOne () to acquire the desired data , that data I want to pass to the client through a variable. I've searched on Google but I get solutions using engines and the truth is that I use pure HTML. Anyone give me the green light? How do I pass variables from Express to client Javascript and then display them in the view?

There are two ways to send data from the server so that it is displayed on the client:

Using your node server as a REST API that returns an exchange format as JSON

Skip what you get from mongo and send it to a template engine template engines

The one you choose will depend a lot on the way you are doing your application, the first option is used for the SPA (Single Page Application), the second would be for a traditional website (as you would with Laravel, Rails or Django ) where you pass the information to the template, it gets the data and translates it into the html.
