Amazon or Flipkart is webapps? And how it's works?

Question

Means how it works in same database on website or apps in same content?
Or it is easy to build this ? And what should I learn for making mini apps like Amazon or Flipkart?

Answer 1

Firstly you have to build a database, either Structured or Non-structured.

Structured database is SQL, you can use MySQL or SQLite.

NoSQL is such as MongoDB.

Then, build your own RESTful API to access your database.

You can use Node.js which is backend with JavaScript syntax.

If you can afford, follow this tutorial :

Answer 2

Please elaborate your question more.

But if you want to make these types of web apps first you need to learn all frontend technologies like HTML, CSS, javascript and bootstrap etc. Also, learn some of the javascript libraries and frameworks.
Then for backend, you can use PHP but most probably this web apps use advanced backend technologies like Django(python framework) or maybe asp.net etc.
Django is best for these types of web apps actually i have also made the same web app like Amazon with Django and it's very easy in Django.
For the database, you can use SQL or MongoDB but with Django, you also got an SQLite database service automatically you can switch if you want.
Admin panel is already made by Django so it's easy to add data in the database.
