Firebase, Get random data ?, Create Filters Complexes [closed]

Navigation
0

I'm programming an app similar to Pinterest and I'm currently using ionic and firebase, but I do not know if it's a good idea to continue using them, since firebase presents some limitations such as not being able to get a Random get from a list of data or the possibility of making complex filters, and I'm really missing a lot of time in very simple functionalities that should come out fast.

1-Somebody could explain to me how to do a Random get from a data list with Realtime database.

2-You could give me an example of how to make complex filters to get very specific data.

how are you !? I recommend you learn about

  • Angular.JS
  • Node.JS
  • MongoDB

    • Through these frameworks as express.JS it is possible to create a web page currently known as App. These are handled with Api (REST) which achieves incredible speed.

    I hope I helped you. Greetings, Charly G.

    Firebase

     I would say that you should do it with Firebase since it is a super and adaptable tool, with it you can make a single structure of databases and adapt it to web, android and ios. The power of firebase is unlimited and with the new adaptations, realtime database, autentication, cloud messagin, you can do everything, it is also very easy to use if you already know a bit of the subject, the problem with native applications is that it would end the long harming the performance of your app, so I recommend you use firebase instead of any framework to make hybrid apps
