About

The SettleMint TheGraph SDK provides a seamless way to interact with TheGraph APIs for blockchain data indexing and querying. It enables you to easily create and manage subgraphs, define schemas, and query indexed blockchain data using GraphQL from your SettleMint-powered blockchain networks.

The SDK offers a type-safe interface for all TheGraph operations, with comprehensive error handling and validation. It integrates smoothly with modern TypeScript applications while providing a simple and intuitive developer experience.

For detailed information about using TheGraph with the SettleMint platform, check out our official documentation.

API Reference

Functions

createTheGraphClient()

createTheGraphClient<Setup>(options, clientOptions?): object

Defined in: sdk/thegraph/src/thegraph.ts:121

Creates a TheGraph GraphQL client with proper type safety using gql.tada

Type Parameters

Parameters

Returns

object

An object containing: - client: The configured GraphQL client instance - graphql: The initialized gql.tada function for type-safe queries

Throws

Will throw an error if the options fail validation against ClientOptionsSchema

Example

import { createTheGraphClient } from '@settlemint/sdk-thegraph';
import type { introspection } from '@schemas/the-graph-env-starterkits';

// Server-side usage
const { client, graphql } = createTheGraphClient<{
  introspection: introspection;
  disableMasking: true;
  scalars: {
    DateTime: Date;
    JSON: Record<string, unknown>;
    Bytes: string;
    Int8: string;
    BigInt: string;
    BigDecimal: string;
    Timestamp: string;
  };
}>({
  instances: JSON.parse(process.env.SETTLEMINT_THEGRAPH_SUBGRAPHS_ENDPOINTS || '[]'),
  accessToken: process.env.SETTLEMINT_ACCESS_TOKEN!,
  subgraphName: 'starterkits'
});

// Browser-side usage
const { client, graphql } = createTheGraphClient<{
  introspection: introspection;
  disableMasking: true;
  scalars: {
    DateTime: Date;
    JSON: Record<string, unknown>;
    Bytes: string;
    Int8: string;
    BigInt: string;
    BigDecimal: string;
    Timestamp: string;
  };
}>({
  subgraphName: 'starterkits'
});

// Making GraphQL queries
const query = graphql(`
  query SearchAssets {
    assets {
      id
      name
      symbol
    }
  }
`);

const result = await client.request(query);

Type Aliases

ClientOptions

ClientOptions: { accessToken: string; instances: string[]; runtime: "server"; subgraphName: string; } | { runtime: "browser"; subgraphName: string; }

Defined in: sdk/thegraph/src/thegraph.ts:34

Type definition for client options derived from the ClientOptionsSchema

RequestConfig

RequestConfig: ConstructorParameters<*typeof* GraphQLClient>[1]

Defined in: sdk/thegraph/src/thegraph.ts:10

Type definition for GraphQL client configuration options

Variables

ClientOptionsSchema

const ClientOptionsSchema: ZodDiscriminatedUnion<ClientOptions>

Defined in: sdk/thegraph/src/thegraph.ts:18

Schema for validating client options for the TheGraph client. Defines two possible runtime configurations:

1. Server-side with instance URLs, access token and subgraph name
2. Browser-side with just subgraph name
