The Graph

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.

API Reference

Functions

createTheGraphClient()

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

Defined in: sdk/thegraph/src/thegraph.ts:90

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

Type Parameters

Type Parameter

Parameters

Parameter	Type	Description
`options`	{ `accessToken`: `string`; `cache?`: `"default"` \| `"force-cache"` \| `"no-cache"` \| `"no-store"` \| `"only-if-cached"` \| `"reload"`; `instances`: `string`[]; `subgraphName`: `string`; }	Configuration options for the client including instance URLs, access token and subgraph name
`options.accessToken`	`string`	-
`options.cache?`	`"default"` \| `"force-cache"` \| `"no-cache"` \| `"no-store"` \| `"only-if-cached"` \| `"reload"`	-
`options.instances?`	`string`[]	-
`options.subgraphName?`	`string`	-
`clientOptions?`	`RequestConfig`	Optional GraphQL client configuration options

Returns

object

An object containing:

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

Name	Type	Defined in
`client`	`GraphQLClient`	sdk/thegraph/src/thegraph.ts:94
`graphql`	`initGraphQLTada`<`Setup`>	sdk/thegraph/src/thegraph.ts:95

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-kits';
import { createLogger, requestLogger } from '@settlemint/sdk-utils/logging';

const logger = createLogger();

const { client, graphql } = createTheGraphClient<{
  introspection: introspection;
  disableMasking: true;
  scalars: {
    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: 'kits'
}, {
  fetch: requestLogger(logger, "the-graph-kits", fetch) as typeof fetch,
});

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

const result = await client.request(query);
