require path in browserify is not recognized - javascript

I have below project structure as shown in the screenshot below. Both index.js and test.js are located at the same path i.e. ./assets/js/ but still the path is not recognized. The error says
Error: Cannot find module 'test.js' from
'C:\Users\meghshyam\desktop\browserifyproj\assets\js'

Use var test = require('./test.js');
This way you are letting node know that its a file in the same folder

Trying Repo Github repository, but error showing Error: ENOENT: no such file or directory

https://github.com/Akshitaag/ACM-WH
I repo this in vs code and tried running it as shown
The project started on server but showing error while trying to use register
Error: ENOENT: no such file or directory, stat '/Users/rajivjain/Desktop/ACM-WH/C:/Users/hp/ACM-WH/public/register.html'
Help me solve this
Found the issue. If you check the "routes" directory, then take a look at where the register route is taking you, its file path is linked as this:
router.get("/register",function(req,res){
//res.sendFile("/home/rahmeen/Desktop/ACM-WH/public/register.html");
res.sendFile("C:/Users/hp/ACM-WH/public/register.html");
});
The issue with this is that it's linking to the route the file is in starting with the developer's C drive.
It seems like the developers have not yet discovered the proper usage of the path module, which is a module baked into Node; however, they are using it within the server.js.
Try replacing that entire route code referenced above with this:
const path = require('path');
router.get("/register",function(req,res){
res.sendFile(path.join(__dirname + '/register.html'));
});
I'd also recommend cleaning up the file structure of this repo.

Problem writing to file fs module, apparently the path is positioned at the root level

I'm practicing with typescript and I want to write a file using fs module but I don't know if is this a noob question or I'm doing something wrong but my project look like this:
root
-> dir (here are the js result from tsc)
-> src
--> data
---> data.json
--> service
---> service.ts
--> index.ts
-> package.json
-> tsconfig.json
And at service.ts apparently the path is:
let filePath = path.join('./','src','data','data.json') // this works
fs.writeFile(filePath, JSON.stringify(data,null,2), 'utf8', (err)=>{ if(err){ return console.log(err);}})
So I don't know why the path is positioned at the root level
If I try "../data/data.json" I get ENOENT ERROR no such file or directory
Is it ok?
Filesystem operations with relative paths always use the Current Working Directory - a concept explained here: https://en.m.wikipedia.org/wiki/Working_directory
When you run Node.js, you do so while being in a particular directory. For example, scripts such as npm start are usually executed in the root-level directory of a repository/project - this causes all relative paths to resolve starting from there. Note, however, that this may be different in production - it is possible for Docker, PM2, systemd, or any other tool to run your script while being in a different working directory (this can often be configured).
To inspect your current working directory in Node.js, use https://nodejs.org/api/process.html#processcwd
It is also possible to build paths relative to the directory of the JS file. This tutorial shows various examples on how to do that: https://www.digitalocean.com/community/tutorials/nodejs-how-to-use__dirname
It is important to remember that require() uses paths relative to __dirname, but fs resolves relative to CWD.

Node.js require local file throws an error

This is my project's filesystem.
root
index.js
package.json
...etc
commamds
- ping.js
- eval.js
- ...etc
This is a normal discord.js bot.
But when I try reloading the commands, I use the following code:
...etc
let pull = require(`./${file}`);
// file is command files from fs.readdirSync() and it can be 'ping.js', 'eval.js', ...
...etc
But it throws a referenceerror that the module can't be found. But when I try fs.readFile(), it works. What's the problem?
fs.readFile() defaults to the current working directory if there is no path or if there's a relative path on the filename.
require() has a completely separate set of rules for where it looks for files. For example, a filename with no path at all looks in the node_modules directory and in the global module location(s). A filename starting with ./ looks in the current module's home directory. And so on... It's a different set of rules than fs.readFile().
Since you don't show us what file actually is, it's hard to know precisely, but perhaps you need to combine the filename with the appropriate path so you are giving require() a full path name and it will go exactly there, not use the normal rules for where require() looks when given only a plain filename.

Node.js - Error: Cannot find module 'config/chgpass'

I created the files following the tutorial (http://dataops.co/android-login-registration-system-with-node-js-and-mongodb/), but unfortunately the error is shown like in the image.
I'm new to node.js and to this kind of programming.
PS.: All of the other files that are referred in the tutorial are right, and the chgpass.js is in the target folder.
Code from the file that requests the chgpass.js file AND the tree from the folder (open with Word and select MS-DOS):
http://www.mediafire.com/download/w283nsjuuj9j794/File-Folder.txt
As your config folder is inside of node_modules folder, thus use:
var chgpass = require('config/chgpass');
Explanation:
In tutorial config folder is inside node_modules that way you can directly access it using require('config/chgpass')
But if you put outside of node_modules then you have to give the complete path of the folder from the location you are requiring it. That is in your case: require('../config/chgpass')

require a file outside of node_modules with grunt

I am trying to require a node module that is used in my app into my gruntfile.js but whatever I do i get : Cannot find module 'appjs/config
In the gruntfile I simply do : var myconfig = require('appjs/config');
But it just don't want to load, is there a way to import this files easily? I also tried various path but appjs is at the root where the gruntfile is.
Have you tried this?
var myconfig = require('./appjs/config');
Seems like this should work, if appjs is in the same directory as your gruntfile.
