Why TransactionReceipt.to can't be null

[shunjizhan]

in the type definition TransactionReceipt must have a string to

ethers.js/packages/abstract-provider/src.ts/index.ts

Line 106 in b145898

to: string;

but in eth wiki it says to can be null: https://eth.wiki/json-rpc/API#eth_gettransactionreceipt

to: DATA, 20 Bytes - address of the receiver. null when its a contract creation transaction.

Am I missing anything? And I wonder where can I find the source of truth for all these ETH related type definitions? Thanks!

Ethers is an abstraction over the RPC. You should not compare them expecting them to be the same. The names and types may not be exactly same. For example in JSON RPC, there is input while in case of ethers it's called data, similarly for gas in rpc spec and gasLimit in ethers. Similarly ethers has to which is string and a null value is equivalent to a zero address.
