How to query for all Contract events?

[mikevercoelen]

I need to index all the event logs from my contract every x seconds and sync them into a MongoDB instance.

What's the best way to do this?

I'm currently using provider.getLogs(...) with the contract address, but that gives me data that doesn't tell me exactly which event it was etc.

Is there a way to get this info from each log entry?

Is there an alternative way? How are others doing this?

You should be able to use use your contract object with the wildcard event:

const events = await contract.queryFilter("*", fromBlock, toBlock)

Let me know if that doesn't work for your purposes...

Im trying to use function to retrieve all events from contract, but it doesnt compile when i put "*" as an event log. Btw i use Hardhat and TypeScipt. Did you have this problem?

[ricmoo]

The "*" should work. Maybe their types are more restrictive?

[chubidursel]

Yeah I belive so. Compiler says this: Type '"*"' has no properties in common with type 'TypedEventFilter<TypedEvent<any, any>>

And also I searched about getting events from smart contract, and almost everyone say that I have to specify the name of Event i want to retrieve, is it true?

if i want to query all contract transfer event, support new Contract("*", abi, provider) ?like contractA hava a transfer event,contractB have the same event,i want to query all contractA and contractB event

Hey @forvicky, support for multiple addresses was added in v6 so you should be able to use provider.getLogs api to passin multiple contract addresses. (related issue)
