SubQuery - Indexer Project for Nova Spektr

SubQuery is a fast, flexible, and reliable open-source data indexer that provides you with custom APIs for your web3 project across all of our supported networks. To learn about how to get started with SubQuery, visit our docs.

Start

First, install SubQuery CLI globally on your terminal by using NPM npm install -g @subql/cli

Install dependencies with yarn install, or npm install!

Cleanup the project

To make sure you start from a clean plate, make sure you have no previous docker running or older db

# delete any docker
docker rm -f $(docker-compose ps -a -q);

# delete the local DB files and build
sudo rm -rf .data/;
sudo rm -rf dist/;

Run this project

Copy one of the chain files into project.yaml: e.g for polkadot cp polkadot.yaml project.yaml

Then the simplest way to run your project is by running yarn dev or npm run dev. This does all of the following:

  1. yarn codegen - Generates types from the GraphQL schema definition and contract ABIs and saves them in the /src/types directory. This must be done after each change to the schema.graphql file or the contract ABIs
  2. yarn build - Builds and packages the SubQuery project into the /dist directory
  3. docker-compose pull && docker-compose up - Runs a Docker container with an indexer, PostgeSQL DB, and a query service. This requires Docker to be installed and running locally. The configuration for this container is set from your docker-compose.yml

You can observe the three services start, and once all are running (it may take a few minutes on your first start), please open your browser and head to http://localhost:3000 - you should see a GraphQL playground showing with the schemas ready to query. Read the docs for more information or explore the possible service configuration for running SubQuery.

Helper script

You can also use local-runner.sh that will perform the above steps for you. Make sure it's executable with chmod u+u ./local-runner.sh.

Query your project

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

{
  query {
    accounts(first: 5) {
      nodes {
        id
        address
        threshold
        isMultisig
        signatories {
          nodes {
            signatory {
              id
              address
            }
          }
        }
      }
    }
  }
  query {
    pureProxies(first: 5) {
      nodes {
        blockNumber
        id
        extrinsicIndex
      }
    }
  }
}

You can explore the different possible queries and entities to help you with GraphQL using the documentation draw on the right.
