How to build a tiktok like video upload and video feed function in a react native app? - database

I have no experience or idea about how video upload and streaming works at the backend, and I am trying to build a tiktok-like app, so if you can share directions on how to approach this, where to learn more, where to find resources, what libraries to use, what database to use, or anything that could be helpful, even if one line advice, I would really appreciate that.
I understand there is going to be a lot of code and that could be out of scope here, but any direction/advice would be helpful.

Designing window frames (of real houses) with React

In my new project with React, I need to implement an environment for designing doors and windows so that the user can design frames through the browser (like the two figures below) and then save it on the server-side. Then I have to fetch and display it in the mobile application that is implemented with React Native. I searched for it but couldn't find anything special that would work. I even found "konvajs" that has done some work in this area but it doesn't work for me and I think I need to develop this feature myself. If you know of any tools or technologies for this, please let me know. If not, what do you think I can do about it?

Splitting up React-Native code: General Practices

I am building a React-Native app social media application, and I am really struggling with fitting everything together.
I want to make very modular code, hopefully splitting up my JSX, my JavaScript functions, and all of my redux and redux-persist stuff (unsure how to go about using these as well and where to split up using action creators and just normal functions.) However, I am really just unsure of a good file structure to maintain all of these things properly.
I am open to any suggestions and would really appreciate some good sample code.
Below image is the folder structure to follow for a React and react-native app. Please let me know if you need in-depth detail of the structure shared in image

How can you build React on top of Drupal?

I've never used Drupal, but have been looking up tutorials online. My client would really like the adaptability of React and to have more flexibility in terms of design. I could make my own database and React app, but I have not studied security (I'm a team of one, so no one for security on my end, either). Security and access to a content management system was the main reason we decided to go with Drupal. However, I would still like to be able to code in React/something I'm familiar with to produce a site I am proud to say I made.
I've been Googling and Youtubing tutorials and help, but not having anyone to ask specific questions is making this difficult.
If anyone knows of a relatively easy way to build a React app on Drupal, I would really appreciate the advice. Or if there is a better way I should go about beginning a project as I've briefly mentioned above, I would also be open to that. Thank you in advance and sorry for the long message!
What you are asking is quite broad in concept and not easy to answer in just one answer post. Try to look for Headless / Decoupled Drupal.
https://www.acquia.com/drupal/decoupled-drupal
What this essentially means is that all the services and the content management are handled by Drupal while the core user experience or the way the site is displayed in a browser is controlled via a JavaScript framework such as React.js or backbone.js. This is achieved via Drupal’s RESTful API service.
Hope this helps.

Adding a qr scanner to a mobile app

I am currently building a mobile app using angularJS, on plunker. The app once complete will be used on iPhone and android devices and will need to be able to access the camera and scan a QR code.
What i'm struggling with is how to go about this. I have done some research and found a lot of github solutions such as -
https://github.com/sembrestels/angular-qr-scanner
https://github.com/blockchain/bc-qr-reader
However I am unsure of how to add these to a plunker built app or if it is even possible?
One idea I have had whilst looking online is to make use of HTML5 and getusermedia to access a devices camera. Although then using this to scan a QR code is quite beyond me.
I am quite new to all this, and if I am honest not very confident at all. Any recommendations will be greatly appreciated.

Want to "screen-scrape" a Silverlight application

I have to use a cumbersome Silverlight application that I don't own and that I have to use as part of my job. In the past a web application that was painful to use I would just "screen-scrape" by doing direct posts, using a browser object to manipulate, call JS directly, but Silverlight doesn't make that possible as far as I know and the company that owns the application says a programmatic API for the application (WSDL/REST) is "something we are considering in the future". I'm sure someone has figured out how to do this but I'm not searching with the right key-words. Any help is GREATLY appreciated!
I am in the similar situation and saw ppl suggested something like `teststack' or 'white'. But i don't know how to use them yet.
One dumb way I can think of is to save the 'screen shots' as jpg files and use machine learning algorithm to 'read' the information you needed.
