Hello guys, I have a small project with Nodejs and I want to read and get all data from a .txt file. I used fs package as below:
fs = require('fs');
fs.open('/data/product.txt', 'wx', (err, fd) => {
if (err) {
if (err.code === 'EXIST') {
console.error('product already exists');
return;
}
throw err;
}
console.log(fd);
});When running the above code I got an exception throw: ReferenceError: fs is not defined.
fs = require('fs');
^

at bootstrap_node.js:508:3I really installed fs package by running command npm i fs.
I'm using Node v12.18.3.
Thank you for any suggestions.

You can try to you
var,constorletto declarefsvariable. You can try to replace:fs = require('fs');to
var fs = require('fs');It's really worked for me.
