Organizations
This is the main connector of the Aragon Connect library. It is responsible for parsing the organization’s data.
Currently a single flavor of this connector is available and comes built into the core library, connecting to a Subgraph (The Graph) data source,. We have plans to expand to other flavors, like an Ethereum connector that reduces the state directly from an Ethereum node’s JSON-RPC API, or a SQL connector that fetches data from a database, etc.
Connector Interface
An organization connector must implement the IOrganizationConnector interface to be compatible with Aragon Connect.
The Graph Connector
This connector was built using The Graph and uses GraphQL as a query language for fetching data.
GraphQLWrapper
The Graph connector exports the
GraphQLWrapper object. The wrapper is useful when you want to create low level requests and talk to the Subgraph directly.To create a wrapper instance you need to provide the Subgraph URL endpoint:
1
const wrapper = new GraphQLWrapper(SUBGRAPH_URL)
Copied!
Once you have a wrapper instance you can use the following API to create custom queries.
API
GraphQLWrapper#performQuery(query, args)
Perform a GraphQL query.
Name
Type
Description
queryDocumentNodeGraphQL query parsed in the standard GraphQL AST.
argsany = {}Arguments to pass to fields in the query.
returns
Promise<QueryResult>Query result data.
GraphQLWrapper#performQueryWithParser(query, args, parser)
Perform a GraphQL query and parse the result.
Name
Type
Description
queryDocumentNodeGraphQL query parsed in the standard GraphQL AST.
argsany = {}Arguments to pass to fields in the query.
parser(data: any) => anyParser function.
returns
Promise<any>Query result data parsed.
GraphQLWrapper#subscribeToQuery(query, args, callback)
Create a GraphQL subscription.
Name
Type
Description
queryDocumentNodeGraphQL query parsed in the standard GraphQL AST.
argsany = {}Arguments to pass to fields in the query.
callback(error: Error, result: QueryResult) => voidCallback function call on every data update.
returns
{ unsubscribe: () => void }Subscription handler.
GraphQLWrapper#subscribeToQueryWithParser(query, args, callback, parser)
Create a GraphQL subscription and parse the emitted results.
Name
Type
Description

callback(error: Error, result: any) => voidCallback function call on every data update.
parser(data: any) => anyParser function.
returns
{ unsubscribe: () => void }Subscription handler.
Subgraph Schema
The Subgraph schema defines all of the available entities and attributes. It may be useful to gain a fuller, clearer picture of the information you can request.
