I am using mongo database with mongoose (ORM). I have a database that is working well with Express framework Application. Now I want to connect to this database with another Express Application.
Now here is the question,
should I make all mongoose models again in new project with Mongoose ? if not then what will be best option for this that we can use still use existing database mongoose.
I am assuming you are not serving the data via a REST API then. If you create a REST API for the mongoose models and then serve that data through URL's you won't have to create new models, rather you could just request the data via HTTP through GET, POST, DELETE, etc requests from the new express application.
If you want me to elaborate further, I can certainty do so.

I have a backend application built with node.js. Every time there is a change in the database I want to reflect it in my ReactJs interface. (Like listing products or updating posts). I use mongodb as database and mongoose as ORM. How can I do that?
You need to use something that's call WebHook. Webhook Article
I have a pretty large MongoDB server running on my local machine, I know how to create an API using Express & Node.js and know how to use routes, etc. But I only know how to add new data to a route using the POST method. My database has tens of thousands of entries in different collections and so it would be impossible to add them all manually.
I wanted to know if there was a way to quickly convert my entire mongodb local database into an API with Express so I can access it client-side from my React.js application.
How does fetching records from mongoose find() and updating records with updateOne work exactly.
I am unable to find it on social media..
When a GET request arrived to route handler. Will data fetch from db and maps to schema or will it get records directly from db?
Please explain the proper workflow. What happen when request arrives and how the mapping from db to schema works in CRUD?
Making the assumption that you are also using a framework like expressjs, a GET request does not go directly to mongodb
within a framework like express, you write a handler to handle GET/POST/PATCH/DELETE/PUT etc. within each of those routes you would write your code to interact with mongoose (mongodb)
for reference here is a
basic entry level NODEJS app
I have my SQL Server database - how should I use model query instead of raw query in node js express framework. Is there any way that we can create models for the tables and fetch the result?
ORMs or Object Relational Models are used to interact and perform CRUD operations on a DB server without writing out raw query.
Sequelize is a pretty good ORM for SQL databases in node.js

I am creating a progressive web app that that is using NodeJS and Express as backend, MongoDB as server, and IndexedDB for storing data locally when offline.
Currently I have defined some Mongoose schema models, and my application is suppose to fetch the data from my MongoDB server and store it into my local IndexedDB when the application goes online. Is it possible to make my IndexedDB's indexes follow the format of my Mongoose schema models, so that if I made some changes to the models, the IndexedDB's indexes will follow the changes as well.
The question is not so clear, an example would have help. But from what I understand, you want to be able to change the schema in MongoDB without breaking the documents saved in IndexedDB and you don't want to update the schema in IndexedDB each time you change the schema in MongoDB. You could use PouchDB which can use IndexedDB behind the scene and it would you to match the same schema as in your MongoDB. PouchDB integrates very well with MongoDB. Thus, if you model changes in MongoDB, when the document is eventually saved on PouchDB (IndexedDB), the document would have the same schema! For your info, PouchDB is the equivalent of MongoDB but in a browser.
