I am using Angular2 and nodeJS (loopback) for my application. I want to upload a large file to my backend server as I have not tried much code for file uploading.
So can someone help me with some efficient way to make a large file upload fast?
Also as per my understanding Angular works on the client side so file uploading will be done by nodeJs, right?
Another thing will breaking the large file into chunks and then uploading will help?
If yes then how will those multiple chunks are can be merged at backend node (loopback).

Earlier we were using aws multipart upload. so approach was simple and straightforward. i have to call three apis from my react frontend.multipart upload/chunk url/complete upload.
found this great tutorial on youtube.
I want to upload a large file to azure, not able to find straight forward answer or tutorial.
If you want to upload the file to blob storage programmatically then we can do this by dividing the file in chunks and each chunk will have an id and we upload the chunks separately.
Here we upload each chunk of data with an id and we also store the id in an list and we upload the list itself too.

I am trying to upload file using nodejs & multer.
I am using plesk server and it work probably on my local host but when I trying upload file on server (plesk) I got the 413(Request Entity Too Large).
upload file how size? you can enlarge upload size
However, it is not recommended to be too large
I have built a Node/Express server behind Nginx & a javascript webapp to upload files. The webapp uses multer for uploads. I have adjusted Nginx to accept up to 10GB files.
When I attempt to send a 4GB file, Chrome craps itself with a "stalled" message in the Timing tab. There is no message about the error at /var/logs/nginx/error.log
Is there some practical limit to file upload using multer (multer-s3)? What strategy can I use for uploading large files like this? I have read about 'chunking' in answers from 2012, but surely this is a thoroughly solved problem.
Thank you
I'm about to start a project that will involve the user uploading audioMP3 files less than 16MB, which is less than the maximum file size for mongoDB. I have been searching but with no luck on how to implement this in the server side to recieve the mp3 file, save it to the DB and retrieve in the client. Any one done something similar or got any idea how to implement this specially the node express side.
Yes Thank you, what I finally did was to load the files in AWS and store their url MongoDB, later requested for them in my application and load them in the browser
Clients can upload files by using a Multi-part form post to my node.js application. To handle the file upload I'm using the node-formidable library.
Now, I manage to upload the file in chunks to node but I don't want it to be buffered before it's written to disk. So, I'm trying to understand how I can write the file data chunks to disk when they're received. I don't fully understand the node-formidable api how to acheive.
Can someone give a simple example of how to listen for an incoming file, create a file stream and then access the data coming in and write that data to the stream and finally closing the stream.
Thanks for help!
There is one example here. It doesn't use formidable library but a similar module (multipart). But it explains everything that you have asked for. You can massage it to fit you needs.
Thanks,
