We are want to make a ecommerce website
Welcome to the forum. Can you please explain what you would like help with.
You should provide more information if you want to get proper information or solution.
If your primary goal is to sell something online, then I recommend against trying to build your own ecommerce website from scratch. There are lots of platforms that already have done the technical heavy-lifting so that you can jump straight to customization and getting your products on the market.
If you want to learn how to be a developer and you are specifically interested in building ecommerce platforms, then you need to start with the foundations of web development.
