Subscriber client for Summary blockchain indexer

This is an example client that subscribes to Summary blockchain indexer.

The client will wait for events which represent changes in the results of a GraphQL query, will print them out and exit after three events.

npm start

Subscribes by a default query that waits for the three latest blocks in test goerli chain.

subscription { starknet_goerli_block(limit: 3, order_by: {block_number: desc}) { block_number, block_hash }}

You can pass your own query as an argument. This query waits for the latest events emitted.

npm start 'subscription {starknet_goerli_event(limit: 3, order_by: {id: desc}) {id, name}}'

Note this and the default query order results descending to get the latest. If you query for the first rows the results won't include the latest and won't trigger events.
