query-node

The query-node project contains an input schema (schema.graphql) and mappings for the Joystream content-directory runtime module.

Code generation

We use Hydra-cli to generate a graphql server and a block indexer for joystream chain:

$ cd query-node
$ yarn build

Run mapping processor

Before running mappings make sure indexer(yarn indexer:start) and indexer-api-server (mappings get the chain data from this graphql server) are both running:

yarn processor:start

Query data

Once processor start to store event data you will be able to query this data from http://localhost:4002/graphql.

query {
  channels {
    title
  }
}
