Are there any functionalities available on web3.js to provide the details Etheresacn provides, such as Txn Type, the Base fee per gas, etc.

I am aware of web3.eth.getTransactionReceipt however, it is missing the above attributes.

Here is an example to transaction details on Etherscan (https://etherscan.io/tx/0xfadaad55279b536b18225aec6f485034ab157fefed65b98da14f22954b00c303)

I just connected to Infura node using web3.py and here is output of the following command:

w3.eth.get_transaction(0x847dc489014532d6c8805a9c90260ce67994adedca3598e6ba9e6839d4d472be)

Some details can be computered using the above command.

There is no way to get those information directly. But you can use bytecode as a hint. Here is a link for you to understanding deeply.
