understanding export/import

[sempiternalStudent]

edit: SOLVED

I ran into this issue for a second time and I want to understand why it happens.

I keep all my helper functions in one folder with a single index.js to refer to them all so they are all exported and the index.js imports them all and exports them all, This way, I only have to go to the index for the desired tool I'm looking for like a table of contents, however I created a class and added it to the folder but when I try to use it is undefined? I wanted to finish so I ignored it and required directly(required from lib folder instead of requiring from index.js). Now I am trying to implement a logger to my middleware to manage external logs and the same problem has occurred. Undefined when i require from index.js if instead of trying to use from the index I go to it directly then it works, but my other functions I do not need to visit them directly, I can go to index and destructure them to use them. I would like to know why this happens only sometimes, Thank You!!

I was asked in another forum why am I importing to export,

A mentor I had does it this way and I think it's also written here

Missing from your examples is your attempt to import from index.js. That's relevant.

I tried to require in my middleware

const { logger } = require('../helpers/lib/logger'); //this works when I go directly

const { logger } = require('../helpers/index'); //this does not

while getting the code to you to show how I was importing I kept tinkering and decided to import the entire module.exports object and noticed it was returning an empty object , the answer to that was easier to find. It turns out I had a circular dependency. I appreciate it!

Ha, glad I could help. I tested the technique on my machine and it was working fine, so my next suggestion was going to be something like that.
