So we've got a webpage made with node.js, express and mongodb.
I've got 2 servers in DMZ, not joined to AD.
One of the servers will be serving the webpage, while the other will purely receive and serve videofiles.
The servers are running iis and iisnode.
Currently the page is using multer for uploading files, which works fine for uploading to the same server the code is running on.
Uploading to a separate server is proving to be harder though, and my googling isnt getting me any closer to the solution.
I want the uploads and downloads to go directly between the client and the videoserver, not through the webserver.
Any tips on how to approach this?

I am developing my own website. So far, I've used React for the frontend and Flask for the backend. I've been doing frontend development for a while now but I'm just starting to get into the backend.
From my limited understanding, frameworks like Flask and ExpressJS create their own servers and host data that the frontend can use. It seems to me that that they automatically create websites to host and receive data. In my website, I route the backend to do what I want and use fetch requests with POST and GET from the frontend to communicate.
Although it works, to me, it seems overly complex. Why does the backend need it's own server? It seems unnecessary to create a proxy for the frontend and fetch data. Why can a website not just run custom code in the background, why does it need a service like Flask or ExpressJS to run in the background for it? These backend frameworks run Python or NodeJS in the background, but wouldn't it be much simpler if the website itself could run Python or NodeJS in the background?
I also see that in frameworks like React, you can import things and use modules— like in NodeJS. While importing some modules works, the require keyword is not allowed and normal NodeJS code will not work. Therefore, the backend will not work. Why is this— why can't you just run backend code natively? Instead you have to go through fetch and specify headers to basically translate information from your frontend to your backend.
Forgive my amateur understanding of web development, but the frontend/backend system seems overly complex to me. Thanks in advance.
Why does the backend need it's own server?
Where will the client store data so that when you open the page again the data will still be there? You can use localStorage but this is locked to that particular browser. What if someone logs in on a different device or uses a different browser?
Where will the client get the application from in the first place? Your application needs to be packaged up in a form that can be easily downloaded, and it needs an address to be loaded from. This is all considered "back end" even if you're using a static hosting service like GitHub Pages.
There's a lot of reasons why a back-end exists and needs its own server. Any application with persistent state which is expected to work across different sessions needs at least one of these.
basically I am trying to figure out a way to make a connection between my Discord Bot and my Website, I have some ideas in mind in using GET and POST methods but IDK how to use them in NodeJs nor in the website as I am still new to it, so what I want is to send a packet of data from the website after a submit button and the bot which is hosted locally with the website will receive this data and work with it.
Express is a commonly used web framework for Node that takes care of routing fairly easily. You can see their documentation here.
I thought I had trouble with uploading files with to Google Cloud Storage (GCS), but it looks like there might be something completely different that is wrong. (I am not going to post any code here at the moment because I do not know if it is relevant. I will add code if we find something that could help.)
The situation is this:
I am POSTing (with fetch, using FormData) to a Firebase server.
The server decodes the post with Formidable.
There are (currently) no <input type="file"...> in the form, but this makes no difference.
This works on the local Firebase server, but not on the deployed server.
The deployed server times out.
If I instead of POST use GET the deployed server does not time out.
I have no idea what could be going on here. Ideas?
I am currently working on a small project where I used vue.js to build the front end and express.js for the backend.
For the frontend, I have another express server to just serve the static files and all the requests will be redirected to my backend API with proxy by the frontend server.
For the backend, it is just an Express API app.
Both apps are runing on heroku right now. And my questions is:
What is the best practice to connect the front end and back end server, I did a lot of research online and people are saying backend API are not supposed to be exposed to internet？ I am not sure how I can talk to my backend if it is not on internet.
For the frontend, I can use SSL/TLS to protect the connection. But for frontend to backend server communication, what should I do to protect this data transfer, can I use another SSL/TLS? And should I use some mechanism to verify that the request is sent from my frontend server, not somewhere else? If so, what is the recommanded way to do that?
A lot people say that there should not be direct connection with database, it should go through a web service for security. What does that means? Now in my backend Express app, I have line of mongoose.connect('mongodb://someaddress/myapp'); Is this bad practice? If so, what should I do to make it more secure?
Please try to be more specific, I am still new to theses and try to learn, code examples can really help. Much appreciated!!
Vue and Express apps are written in the same language, so it is best practice to have these as separate projects as you have done. These are entirely different projects doing different things so they should be split.
You already deployed to Heroku, so the SSL/TLS isn't really a concern for you. However if you were deploying to your own VPS, you'd want something like Let's Encrypt. For restricting requests from Express to your Vue app, you'll want to look into CORS. See expressjs/cors for more details.
The Express app is the service connecting to your database. If you were trying to directly connect to your database from your Vue app, then that becomes an issue. You would coupling client side code with server side code. What you're doing is fine.
Let's say I have a domain already running called http://docs.domain.com.
This isn't an express server it's something I don't have control over, however I do have full control over the source files, so I was hoping there's I way with ExpressJs that I can sort of reverse proxy a restful app?
So http://docs.domain.com/app/products and that would get data locally?
Or is there something else I can do with node to save a file locally from the website?
