I am new to nodejs and trying to write this web scraper where I am getting the following errors. It asks to return promise however I tried but nothing works out. Not sure if I am using the right packages. Promises in async is quite difficult to understand for me at this point. Any explanation along with the code will be really apprciated.

fs.readFile("./log.log", (err, file) => { //adding "utf-8" only logs a small portion of the .log file, but I was told this might be an async issue.
console.log(file);
});
};

I would like to console.log() this .log, log file, but it console.log()'s an array buffer.
You're not specifying an encoding, so the file gets read as a Buffer.
If no encoding is specified, then the raw buffer is returned.
If options is a string, then it specifies the encoding:
readFile('/etc/passwd', 'utf8', callback);
const displayLogFile = () => {
fs.readFile("./log.log", "utf8", (err, file) => {
console.log(file);
});
};
to have it decoded into a string (assuming it's encoded in UTF-8).
Here is my database connection code
'use strict';
const config = require('../config');
const Mongoose = require('mongoose').connect(config.dbURI);
const mongoose = require('mongoose');
var options = {
promiseLibrary: require('bluebird'), useNewUrlParser: true, useUnifiedTopology: true
};
var mongodbUri = 'mongodb+srv://chatcat:chatcat#mychatcatdb-xlous.mongodb.net/test?retryWrites=true&w=majority'
mongoose.connect(mongodbUri, options);
var conn = mongoose.connection;
conn.on('error', console.error.bind(console, 'connection error:'));
module.exports = {
Mongoose
}
I'm getting this type of warning. i have also installed all of the packages which is required.
warning is just be like (node:17592) DeprecationWarning, (node:17592) UnhandledPromiseRejectionWarning.
what is the reason behind the this type of Warning ?
i just started learning node js.
please anyone help me to solve this warning?
