Hi!
Sorry, but this is NOT Javascript! This is Node.js. I'm looking for a vanilla javascript solution. Do you have a solution for that?

[Jandhyalas]

Thank you for a short and simple tutorial.. I am new subscriber to your channel🙂

[shanermahmud]

Thanks a million! This is a great tutorial!

Misleading. The title should have Node. People creating a client side app will get an error as "require" is not defined! As well as those with no node installed on their machine

[bhaveshgudlani]

How do you read and write files with Javascript without Node.js?

Thanks @SteamCode for great content.
I had one question though. Recently I was trying to read cert files using similar approach, although when the react project was up on web-dev-server, I was not able to read those files. Is there any restriction with this approach such that when the project is up on some server wr can't read those files?

i need help on how one can read multiple files of same type in a folder then after reading them then create one file which comprises of the data which have been read

I'm using React Nodejs, and I'm getting this error from trying to require "fs", : "ERROR in ./src/App.js 9:11-24
Module not found: Error: Can't resolve 'fs' in '/React/server-test/src' webpack compiled with 1 error and 1 warning"
Why is this happening?

It seems fs.writeFile() and fs.appendFile() perform the same operation? You overwrote the readFile with writeFile then edited with appendFile. Could we not just continually overwrite the existing file and forget appendFile altogether or is there some other benefits I don’t see?

Hey, great tutorial. I was wondering if anyone knows how to save the contents of a file as a variable? I tried saving a content variable as data in the block and it didn’t work. I also tried making as a list and adding to it each iteration but that also didn’t work, and no form of just using the data variable seems to do anything. Sorry if this is a rly simple request an I just don’t see it, I’m new with js so any help is appreciated!

[kozkiroify]

but how do I put the contents of data in a variable outside of "fs.readfile"?
in short, I want to read a file, work with it's contents within my program, then save the results in another .txt

I'm having some issues running node with bash terminal. Following your code on my mac doesn't seem to work, but on my friends windows it works with powershell. Do you know anyway around this?

[abhijithtgcse]

Thanks for this information bro, can we use switch and case to add and read contents on the text file ?
ex: press 1 to add content
press 2 to view content
press 0 to exit

[kezzaman]

how do i get the data out so i can use it?

[jamesharland]

Thanks for this! Is console.err a thing or was that a typo for console.error(err)?

I'm trying to load a text file so I can use the content as values to my variables. I've tried many approaches, but I think this one is the simplest. However, every time I apply this code in my editor I run into the same problem:

( Error: ENOENT: no such file or
errno: -4058,
code: 'ENOENT',
syscall: 'open',
path: the_to_my_file_here....

I tried to change the extension of my text file but it didn't work, I also tried to change the location of my script and the text file, it didn't work also.
I am using :
---VS code
---JavaScript
---file.txt (also tried .csv)
---windows 11
I'm looking forward for your reply.
