Shopware6 rest api for multi image upload - shopware

I am using Shopware 6, I am trying to upload multiple images how to upload multiple images upload by rest Api?

I believe even if you upload multiple images via the backend, it makes separate requests. So I am not sure if there is such a thing like a multi upload.
Additionaly there is usually a size limit due to your web server and PHP settings, so it makes not much sense to combine multiple images into one request.
What keeps you from doing multiple uploads in a loop?

Serving and processing large CSV and XML files from API

I am working on a node web application and require a form to enable users to provide a URL containing a (potentially 100mb) large CSV or XML file. This would then be submitted and trigger the server (Express) to download the file using fetch, process it and then save it to my Postgres database.
The problem I am having is the size of the file. Responses from the API take minutes to return and I'm worried this solution is not optimal for a production application. I've also seen that many servers (including cloud based ones) have response size limits on them, which would obviously be exceeded here.
Is there a better way to do this than simply via a fetch request?
Thanks

NodeJS, how to handle image uploading with MongoDB?

I would like to know what is the best way to handle image uploading and saving the reference to the database. What I'm mostly interested is what order do you do the process in?
Should you upload the images first in the front-end (say Cloudinary), and then call the API with result links to the images and save it to the database?
Or should you upload the images to the server first, and upload them from the back-end and save the reference afterwards?
OR, should you do the image uploading after you save the record in the database and then update it once the images were uploaded?
It really depends on the resources, timeline, and number of images you need to upload daily.
So basically if you have very few images to upload then you can upload that image to your server then upload it to any cloud storage(s3, Cloudinary,..) you are using. As this will be very easy to implement(you can find code snippet over the internet) and you can securely maintain your secret keys/credential to your cloud platform on the server side.
But, according to me best way of doing this will be something like this. I am taking user registration as an example
Make server call to get a temporary credential to upload files on the cloud(Generally, all the providers give this functionality i.e. STS/Signed URL in AWS).
The user will fill up the form and select the image on the client side. When the user clicks the submit button make one call to save the user in the database and start upload with credentials. If possible keep a predictable path for upload. Like for user upload /users/:userId or something like that. this highly depends on your use case.
Now when upload finishes make a server call for acknowledgment and store some flag in the database.
Now advantages of this approach are:
You are completely offloading your server from handling file operations which are pretty heavy and I/O blocking and you are distributing that load to all clients.
If you want to post process the files after upload you can easily integrate this with serverless platforms and do that on there and again offload that.
You can easily provide retry mechanism to your users in case of file upload fails but they won't need to refill the data, just upload the image/file again
You don't need to expose the URL directly to the client for file upload as you are using temporary Creds.
If the significance of the images in your app is high then ideally, you should not complete the transaction until the image is saved. The approach should be to create an object in your code which you will eventually insert into mongodb, start upload of image to cloud and then add the link to this object. Finally then insert this object into mongodb in one go. Do not make repeated calls. Anything before that, raise an error and catch the exception
You can have many answers,
if you are working with big files greater than 16mb please go with gridfs and multer,
( changing the images to a different format and save them to mongoDB)
If your files are actually less than 16 mb, please try using this Converter that changes the image of format jpeg / png to a format of saving to mongodb, and you can see this as an easy alternative for gridfs ,

using backend files nodejs

Sorry, It might be very novice problem but I am new to node and web apps and just have been stuck on this for couples of days.
I have been working with a API called "Face++" that requires user to upload images to detect faces. So basically users needed to upload images to my webapps backend and my backend would do an API request with that image. I somehow managed to upload the files at my node's backend using tutorial provided below but now I am struggling how to use those image files. I really don't know how to have access to those files. I thought writing just the filepath/filename would help but it did not. I am really new at webapps.
I used tutorial from here: https://coligo.io/building-ajax-file-uploader-with-node/
to upload my files at back-end.
thanks
You can also use the Face++ REST API node client
https://www.npmjs.com/package/faceppsdk
As per in documentation it requires a live URL on web. Then you have to upload your files into remote location (You may upload files to a Amazon S3 Bucket)
And also you check the sample codes from Documentation where you can upload directly to Face++

Uploading multiple images for image tagging in a single request to alchemyapi

I am trying to use Node.js with AlchemyAPI for image tagging. How can I upload or provide multiple URLs for multiple images in a single request so that the response contains the tags for all the images ?
If I am adding multiple URLs it gives
"statusInfo": "content-exceeds-size-limit"
AlchemyAPI image tagging handles images one at time. You'll have to submit them individually, not as a batch. You can use multi-processing to increase the speed at which your program runs.

Uploading user images to s3 and generating thumbnails from node

I'm currently considering developing a Meteor node.js app, but am struggling with how best to handle uploading of user images. In particular, I want to create a photography website that will allow the photographer to upload images in an 'admin' section, and these images will then be displayed on the website. I need to create a thumbnail of these images, and save the respective URLs to the database. I'm struggling with how to best accomplish this in meteor.
Is my best bet to use something like s3 combined with an AWS process for generating thumbnails?
Or should I save and host the images directly in the Meteor/node session?
Or should I scrap Meteor and use something like Express.js for this project?
Why don't you just use something like Filepicker.io to handle uploading and hosting images and simply store the image unique url (given to you by filepicker in the callback)?
Thumbnails can also be dynamically generated by Filepicker (using simple url modifications).
Cloudinary is a nicer alternative to filepicker when it comes to images, but integration process will be messier.
I would store the images on the filesystem, not in a database. If you have a unique id, you can use that as part of the url, for example an id of the item the image belongs to. Might look like this:
./uploads/img-<id>-<size>.jpg
You can write to disk and resize if necessary with node-imagemagick and your cdn should just poll these images from time to time. Not exactly sure how that part would work in terms of including the url to the image in the html.
