Calculate amount out offchain

[0xsinhvu]

I tried to wrote CrocImpact (using typescript) to calculate baseFlow & quoteFlow offchain but stuck at readSlot method because we have to read onchain data in here.

The idea is that I want to query some on-chain information (like curve, pool, etc,...), then use them as input data to calculate offchain.

Any suggestions for calculating amount out offchain?

I am currently also trying to integrate crocswap off-chain on our smart order router. And this capability mentioned above would be greatly appreciated.
