Don't use axios for file upload because you need to read the image from the native filesystem. You can use uploadAsync() from the FileSystem module from Expo. Documentation Here

In your case the function call would be:

Not able to figure out why in upload.js file in the below code snippet is throwing me an error: app.get is not a function.

I have an index.js file where I have configured everything exported my app by module.exports = app and also I have app.set("upload") in it, but when I am trying to import app in upload.js file and using it, it is giving an error error: app.get is not a function.

The problem is that you have a circular dependency.

App requires upload, upload requires app.

Try to pass app as a parameter and restructure upload.js to look like:

I am using Multer to upload a maximum of 3 images to the server and it works fine, but when I upload more than 3 images, Multer tells me the error but it is not manageable to show the user.

I'm working on the route that calls the controller but in the Multer documentation it only shows how to handle errors with the route along with the controller actions.

QUESTION

Should I use GridFS or some other method to create a file sharing app?

Asked 2022-Feb-11 at 17:56

I am currently beginning work on a file sharing app for my company. A simple form to upload a file, the user is then given a download URL and can past that on to anyone so they can download the file (Similar to products such as WeTransfer).

However I am struggling on decided how to do it. I have been playing with MongoDB and GridFS. I have successfully used multer and multer-gridfs-storage to upload files directly into my database. I am struggling to get them to download as I don't know that much about GridFS.

...

Answered 2022-Feb-11 at 17:56

GridFS is a specification for storing and retrieving files that exceed the BSON document size limit of 16 MB. GridFS is a convention implemented by all MongoDB drivers that stores binary data across many smaller documents. The binaries are split into the chunks and then the chunks are stored in collections created by GridFS.

Having said that, given the presented use cases i would highly recommend using media server for storage as given the application landscape, that makes a more economical, viable and scalable solution.

Having said that, I would generally, avoid putting BLOBs in the database if there are other storage options that cost less as using a database as BLOB store is generally not a cost optimised solution. Sure, there are valid reasons for storing blobs in the database, but given the application’s use case (it being media intensive), use the media server for file storage, and databases for data structures.

In such cases, It is often easy to get "cost unoptimized" with time. Plus the database size would grow exponentially with time, bringing it's own challenges with RAM (WiredTiger Cache) management.

All in all - if it was me - I would use media storage for BLOB intensive applications than relying on databases.

This is expected, since you are using DiskStorage - the code initializes multer with a "dest" option, so it will save the files locally. Take a look at the multer README - the API doc says in the "Note" column that buffer is for MemoryStorage only.

Therefore, you must decide - do you wish to save the files to the filesystem (and get the path), or load into memory in full (and get the buffer)? In the latter case, the README contains a section called "MemoryStorage" that demonstrates how to configure multer:
