Reading and Writing Files with Node.js | Node JS Beginners Tutorial

Hey, thanks for this! i am really insterested about how things work in a full developed web application, this thing really helped me!

You saved my life!🎉

This course is so underrated, thanks for this Dave!

The best channel ever! Thank you for the awesome tutorial! 💛

Oddly, I followed your code to the letter and the console.log() ends up writing to the console that the writing was complete before it read from the file and I can't ascertain what is different or why this happens.

Thank you!

Loved the tutorial, it'd be nice if you could show us how to stream huge data from backend to frontend in a mern app.

Is that also possible with a button

Hi Dave Grey, i want to read JSON file and keep updating the multiple keys in a JSON file. Can you please help how to achieve that

Thanks for the explanation about why it's better to have the use appened file inside the write file function. I've seen it done before but didn't know why it might be useful. I didn't realize append file was capable of writing a new file also; so now it makes sense to have it operate 'after' write file.

Thank you Dave Gray you're the best

I am loving this series 👍

I love your content so much! Looking forward to new Nodejs tutorial videos. Love from Vietnam <3

Very nice, thank you. At the end with an if-else would be enough? Thank you

This content is by far the best. Thank you for this labor of love. It's going to change my life.

Awesome video Dave! Your video helped me.

callback functions, error handling, async await

Hello. Many thanx for such a wonderful video.
Could you explain, please, this data[, options]. Why is comma insight [ ] ? what does this mean ?

Best of the best of the best. Thanks you

Really really nice!

hey dave i have a issue with createreadstream it works perfectly iam using csv file for reading but 10 out of 1 time my readstream doesnot read my file i dont know why can u please with me with this it would be really greatful

Great video, mate. Though fs.promises could have been explained a bit better, cuz I still don't know what it does exactly :/

existsSync function is behaving different in my code. Even if you write same code, for the first time it only creates new directory and if you run it again it removes the directory. What's reason behind this strange behavior??

What's the difference between writeFile and createWriteStream?

Kind Regards!!

Yoy Save Mi Life with this video!!

Just want to say, GREAT TUTORIAL!!!!, Thank you

Great video Dave, can you advise how can i append content to a specific line? I want to read the content of HTML file (which works), then identify a specific line that contains <title></title> then add user input value from a form, and append another 5 lines of specific content after the title line.

thanks so much for this helpful tutorial

Amazing tutorial thank you

I applied this tutorial to read a JSon file and it worked well! Thank you Dave, you really made this task simple and easy to understand!

It's refreshing to see a tutorial where someone mentions documentation they are using. Most of the times it's "let's put this absolutely cryptic line of code here because I said so".

Super useful.
8 minutes in and you've answered every question I had right now.
(JS noob who installed node for the first time this morning as an alternative to doing everything in dev tools. Been wondering for a while if i could read/write files. Kind of crazy how thrilling it is to be sitting here looking at a list of 20 freshly minted random numbers in a simple ol' text file your tutorial taught me how to create.)
Many Thanks, once again, for sharing your knowledge.
Will be checking out your full node tutorial for sure.
