We should not change the root dir here; this makes the image publish all the code from the repo instead of only the graphql package, drastically increasing the image size.

@luizstacio indeed :(
I'll need to figure out how to get rid of this – let me find a time to check that today.
I've added this because graphql-new package has a peer dependency on the @fuel-explorer/contract-ids.
(Outside that context)
Does that make sense?

How watchLogs work? If the socket is closed as example by the server it autoReconnects?

Add L1 indexer, it'll sync contract events logs from a given start block number.
After that, it'll keep watching the blockchain for new logs and blocks.
New env vars have been added to the graphql:
FUEL_CHAIN_NAME(examplefuelBeta5)ETH_CHAIN_NAME(examplesepolia)ETH_ALCHEMY_ID(your alchemy key)ETH_INFURA_ID(your infura key – used as fallback to alchemy)ETH_INITIAL_BLOCK(block number that got our contracts)📷 Indexer demo
