Im creating a mern app where i have to save profile pictures of users.
My question has 3 parts:
1)What is the best file hosting service (image hosting) to save images in database how to configure it with mern.Im using mongodb.
2)We are planning to deploy the app on aws server later. Should i save it on aws.If yes how(Procedure) and how much it will cost as we are on tight budget right now and not planning to deploy for atleast 5 months.
3)Is there any other cost efficient way ,if yes kindly share it with procedure as im new to web programming.
Images are usually not persisted in a database itself, due to their large size once system gets bigger, but on file system (you can save them into local folder for development purposes, and on AWS for production purposes, for instance). In the database you can keep image data like image file system path, size in pixels etc.

I need to generate an organisational chart for a non-profit organisation using open source / free libraries in Java (or even javascript with NodeJS).
I have an xml containing the data: unluckily I cannot find anywhere the original xsd, based on European Commission's Whoiswho.
The chart should be printed in multiple pdf pages and be able to automatically adapt to the size of A4 pages to be printed (without cutting shapes).
The data should not be shared or sent through the internet for privacy reasons.
I have starting to play in Java with JGraphX/JFreeChart/Java2D with iText for the pdf, but what do you think would be the best libraries to use? I am converned about the rendering in multi pages of the big chart I need to print in pdf.
Another idea is to find something already working and transform the input from my xml to the needed format, keeping in mind that it has to run in local and with no user interaction other than launching a procedure/software: any idea?
Thank you in advance.

I want to make a chat application (something like on how is on Whatsapp Web). I want my application to be on laravel.
I just finished the design and the login system.
My question is about functionality.
Is it enough Laravel and Javascript or do I need something else additional?
I don't need to make a large project, its just for me to start learning the basics things and how they work.
Laravel for backend, JS for frontend
You also need Pusher (if not big project) for (easy) real-time application and pusher-js for subscribe websocket
You need to add a websocket part , in order to make the app real Time.

I would like to publish a website that hosts menus for different restaurant branches.
What would be good way to do publish this?
Bearing in mind occasional price changes - does this mean taking the website down and re-deploying or is there a way I can dynamically update item prices?
Hosting providers/CMS tools appreciated
I have written the website using basic html/css/js so far.. I have only used django to host a website on the local loopback address. I am determined to learn more.
The first question would be can you access the price data online? (Other websites?)
If you are able, to get the data online then you could create a database and small program which fetches the required data for the website. You can then give that a refreshing rate of 5 min or what ever you like.
Then give your website to access the database and load the prices/data from the database into your website.
If you do not have the data online you can still use a database for storing the prices and other data. If you store the data in database you can load it from the database into your website.
To update the data you can either insert the values directly into the database or you can write an webinterface. (Do not forget to restrict the access to the webinterface)
For the communication I would recommend to use CRUD methods ( Create Read Update Delete) https://en.wikipedia.org/wiki/Create,_read,_update_and_delete

I am creating a MERN app. I am wondering if I can connect my computer to a printer from an ip address and that printer is far away.
like we connect with ssh or ip address to connect our web server. in which language it is possible just thinking...
With your app, I think the easiest way is to let the Nodejs handled the auto receipt printing service.
I have created a simple diagram to show you how the system would work.

I'm building a project that requires me to get Pictures, Price & URL of an amazon product.
Each user has his own product, and other users can see other users' products, and i have everything saved in a database, so I was thinking of scraping data but that would be too much on the server to scrape on each request. so I'm trying to find an API where I can get Product URL, Product Image & Product Price from just the keyword of the product.
would love some help.
Keepa API and ProxyCrawl API have this funtionality, but both of these are paid solutions. Also, you will always get multiple products per keyword. If you want a 1:1 match then it's not possible using just a keyword- you would need an identifier like an ASIN.
