Node.js vs PhantomJS

I am a front-end guy and in the last month I've been trynig to be learn backend in python. I think python is a great language to but when i start to learn django I didn't like it because everythong is already done for you, you dont need to do much make it works and I like coding thing that take me time. I've been thinking about switching to another programing language or just learn Node js and stick with it. I need to know if django is that easy.

I want to create a video sharing service like Youtube, which users can use to upload and watch videos. I prefer to use Vue.js for front-end. What do you suggest for the back-end? @{Node.js}|tool:1011| or @{Laravel}|tool:992| ( @{PHP}|tool:991| ) I need a good performance with high speed, and the most important thing is the ability to handle user's requests if the site's traffic increases. I want to create an algorithm that users who watch others videos earn points (randomly but in clear context) If you have anything else to improve, please let me know. For eg: If you prefer React to Vue.js. Thanks in advance

I would like to build a medium to large scale app, that has real-time operations and a good authentication system and a secure and fast API. Should I use Django with React only? Or maybe use Django for the API, Node.js for real-time operations and React for the frontend? Any suggestions? Which database should I use with those technologies? Should I use both MySQL / PostgreSQL and MongoDB together? Should I use only MongoDB or MySQL / PostgreSQL? Or is it better to go with both MySQL and PostgreSQL at the same time? Should I use also GraphQL?
