Astar dApp staking indexer

This is a simple Astar dApp staking indexer. The indexer is based on SubQuery engine and it indexes the following events:

dApp registration
dApp unregistration
stake
unstake
nomination transfer
reward

The indexer has never been used in production. It has been developed as proof of concept. Although all local testing was good, please take the previous sentences into consideration before use this code in real life scenarios.

Preparation

Environment

Typescript are required to compile project and define types.
Both SubQuery CLI and generated Project have dependencies and require Node.
Docker

Install the SubQuery CLI

Install SubQuery CLI globally on your terminal by using NPM:

npm install -g @subql/cli

Initialize indexer

Under the project directory, run following command to install all the dependency.

yarn install

Build the project

yarn codegen
yarn build

Indexing and Query

Run required systems in docker

Start Docker and under the project directory run following command:

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.

You can try to query with the following code to get a taste of how it works.

query {
  stakes(first:10, orderBy: TIMESTAMP_ASC) {
    nodes {
      contract,
      staker,
      amount,
      timestamp,
      block
    }
  }
}

query {
  contracts {
    nodes {
      id,
      owner,
      state,
      blockRegistered,
      blockUnregistered
    }
  }
}
