Node.js File Upload API with Express Tutorial

Thanks sir

This is so helpful!

I'll be so glad if you prepare a video about streams, process, buffers in nodejs, sir :))

thanks for best content

Hey Dave, could you please make a sample tuto for a file upload using GraphQL mutation (file within variables e.g. queryInput: {firstname, lastname, image} ) thanks

please use react to create the form.

can you please do it with react front end

Hey Dave, it would be great if you could make a react frontend form to upload xlsx files (or any other file) like in this video with backend. By the way your react, javascript, node js, css, tailwind courses are top notch, understood all the concepts.

All of the file upload tutorials I've seen other than this one seem to use multer. Do you prefer this method instead of multer?

Hi Dave, do you have a course on Udemy?

Great Video. Text is bold and visible. Explanation is so clear and precise. Excellent delivery.

Thanks for the tutorial!

Btw what extension or setting are you using for highlighting syntax? I noticed that in your editor the opening and closing brackets are connected with a line (not just highlighted) which would be awesome.

Thank you 😀Can I use this method instead of database and send this data to client? Hosting allows such dynamic adding of files or does it only work on localhost?

Thanks Dave, love your tutorial!

I was trying to use an external script for the javascript but it's not working even after using the same code.


What might be the issue?

thank you, this is great , perfect timing, I just happen to need this for my current project. Can you not use axios for this or did you just choose fetch randomly for this example? Can you possibly point me in the right direction on what I would need to research if I wanted to implement a crop photo option before upload or maybe it would be after? It would be to use the image for a profile photo but allow the client to crop it so the most important part of the image is displayed in the bubble.

This is some cool asynchronous upload handling script. Creating formdata object and passing into fetch with await wrapped into async function and then taking resolve in json format with optional chaining. That’s really cool, but why express-fileupload and not Multer as an middleware?

Thanks for creating this video it really help

how to rename the file before saving it to the our folder ?

could you please make a video on websocket

Hi Dave, Just now I have completed the video and tried it - its working well. Of course, it took some time for me to understand the concepts. But overall, really interesting - you did not use even axios or any other extras. Especially you have taken additional efforts to show the error messages without any grammatical issues and you have used middleware for validating the files are amazing. You did a great job and its very useful for the users. Thank you so much for your effort.

I just want to say thank you for sharing your knowledge .... I was here looking for a way to show progress of your file upload while it's uploading but this was still nice to watch as always you explain topics in a very clear way that anyone can understand!

Great course! It helped me so much. I have a question, how do you do to paste code from nowhere?

Thank you very much you help me so much with this video

Dave,

I want to add my compliments to the many you already have!

Your instructions are crystal clear and allowed me to implement your solution into my project with very few updates as changing the repository path for uploaded files and saving the metadata to my database.

I just want to ask you if you have a tutorial on retrieving the files from the server to allow users to open their files.

Thank you very much!

I bought paid courses and this guy channel is better. So crazy 😂😂😂😂😂

Could you please do a file upload with react.

Great tutorial but the entire time I was screaming GET TO THE POINT

loved your video❤

Hey Dave,
Great Course, I've completed ReactJS and JavaScript playlists too from you. Your explanations are crystal clear and to the point.

Thanks for the great quality content Dave. Have a great day.

👍👍👍👍👍👍👍👍👍👍👍👍

How about a tutorial on express.js file upload without using packages like multer or express file upload.

What did the semicolon ever do to hurt you? Why don't you show my boy some love );

Really good tutorial, thanks! Based on this, is it possible to integrate a progress bar in the frontend?

i like how you clearly explain; you got a new subscriber ✌️

You tackle the hardest topics that others evade

Awesome Tutorial +++++++++++++++++++++++++ Thank You

Hey Dave,
awesome tutorial , can you please tell me how I can change the path of saved files meaning if I want to save somewhere else and divide them into different folders like image files separated from doc files.

Hey Dave,
Great explanations and methods. I’ve been trying to create a React app and do some pre-processing there.
Scenario 1:
- I don’t need to store the file, but I need to process csv data. So I validate the file extension, headers, etc. in React and then push the data to the API once the file and data checks out.
- my struggle with this is providing loading status for multiple files. I use a state array, but doesn’t always re-render the component for some reason until another state change later.

Scenario 2:
- uploading jpg files. This video couldn’t have come at a better time!
- is it better to process the file with express? Or should some preprocessing be done with react?

In both scenarios I am playing with react-dropzone vs standard input field and button. Appreciate and value your thoughts.

very interesting material, permission to ask, how to upload this file consumed by api gateway? does the api gateway also have to have a multer and a storage folder? thanks

Thanks Dave what an amazing tutorial 👏
Appreciate if you can extend the tutorial to cover converting images to base64 string type and then save it to database
Thanks again.

Hey thanks for this! Can I upload csv file and convert it to JSON or object?

Hey Dave,
any plans of launching a paid course

Dave you can create React JS for this file upload

take love

Thank you for your video, Dave! Can you also make the video about the download file with express? Please.
