Launching mongodb on Termux error ECONNREFUSED

Question

I'm beginner in node.js and trying to run mongodb.
It works well with remote connection link, but I have no stable internet connection, so I need to deal with it locally on Android device + Termux. And I haven't found solution of this problem specifically for Termux.

Package npm mongodb is installed.

Just simple connection code:

const mongoose = require('mongoose')
const url = `mongodb://127.0.0.1:27017/myapp`;

mongoose.connect(url)
.then(() => console.log("Connected to mongodb successfully"))
.catch((err) => console.error(err))

The error details:
