yarn build

Indexing and Query

Run required systems in docker

docker-compose pull && docker-compose up

Query the project

Open your browser and head to http://localhost:3000.

Finally, you should see a GraphQL playground is showing in the explorer and the schemas that ready to query.

For the subql-starter project, you can try to query with the following code to get a taste of how it works.

All stakers with their stake

query{
    accounts (
        filter: { totalStake : {notEqualTo: "0"}}
    ) {
        totalCount
        nodes{
            id
            totalStake
        }
    }
}

Query given stakers

query{
    accounts (
        filter:{
            id:{
                in: [
                    "..."
                ]
            }
        }
    ){
        nodes {
            id
            totalStake
        }
    }
}

Some statistics

query{
    accounts (
        filter: { totalStake : {notEqualTo: "0"}}
    ) {
        totalCount
        aggregates {
            sum {totalStake}
            min {totalStake}
            max {totalStake}
            average {totalStake}
        }
    }
}

All stakers with operations (stake/unstake/nominationTranfer)

query{
    accounts {
        totalCount
        nodes{
            id
            totalStake
            stakes {
                nodes {

                    amount
                }
            }
            unstakes {
                nodes {
                    id
                    amount

            }
            nominationTransferIn {
                nodes {
                    id
                    amount
                }
            }
            nominationTransferOut {
                nodes {
                    id
                    amount
