How can I perform a pre-check transaction to verify if it will be successful without recording it on the blockchain?

We aim to implement transaction checking, specifically for swaps, to ensure they won't be reverted. This will help users avoid unnecessary gas costs.

I want to do this on the front-end, using the ether.js library. Or any other library.

Not sure if this can help, but maybe you can look for the method estimateGas, docs.ethers.org/v5/api/contract/contract/#contract-estimateGas. Maybe it fails if tx is reverted. Not sure.

From ethers you can use staticCall.
