I would like to know, what is the problem that you guys face and wish there was an NPM package for it?

I have these series of questions for all the developers out there.

__________________________________________________________.
1. Problem statement (wish there was NPM package for that)

2. What are the major setbacks in the NPM package that exists already as a solution for these NPM packages?

3. What would be your ideal solution for your problem statements?

This particular survey is just to know the need of the fellow developers out there and help them work through the same.

Please, do drop your input. It would mean a lot.
Every response and feedback will be taken into consideration.

Node.js : Winston Logging

dev — Wed, 05 Aug 2020 16:40:47 +0000

Hey,

I am working on Nodejs and building a logger for the application I am working on. I am using Winston for logging purposes. I am having issues with logging the module/file name from where I am logging it.

If anyone has worked on it, can you please guide on the same. I do not want alternates for Winston, if anyone could help me with it please drop it in the comments.

It will be very useful.

Disclaimer : Don't give StackOverflow answers, I have tried them already. Apart from that, anything solution would do.```



Thanks :)

Logging using ELK for Nodejs

dev — Tue, 28 Jul 2020 11:26:06 +0000

I needed guidance regarding how to setup Nodejs for logging using Elastic Search, Logstash, and Kibana.

I need suggestions for proper NPM packages for the same.
If there is any other alternate, please feel free to suggest.

Any example code snippet would also be great! :)

JS Array

dev — Wed, 15 Jul 2020 04:42:45 +0000

Recently read an article on medium about JS Arrays which said as follows:

In Js, an array internally is also an object only

for a regular array like this
['a','b','c'] its equivalent object is { 0: 'a', 1: 'b', 2:'c', length: 3}
This is by definition a dense array

In JS, there is also the concept of sparse array
['a', , 'c'] its equivalent object is { 0: 'a', 2:'c', length: 3}

The empty hole we refer to is called an Elision

So in order to replicate holes/Elision , you just need not set the index values in the object but set the length property,

[,] equivalent is {length: 1}

but if you try
a = [,]; b = [undefined];
a[0] === b[0], it will return true though a[0] is an elision
because technically, elision is treated as an undefined value

but when u represent a = [,], the browser sees the length property of the object a and finds 1

But if it accesses the index 0, it hasn't been set also doesn't have a value and hence its undefined, but its represented as a hole/elision (as [empty] in chrome v8)

So basically in Js a hole/elision is created when there is a mismatch between index assignment and length property of an object (of type array)
