@onelabs/graphql-transport v0.2.48

@onelabs/graphql-transport

This package provides a SuiTransport that enables SuiClient to make requests using the RPC 2.0 (GraphQL) API instead of the JSON RPC API.

Install

npm install --save @onelabs/graphql-transport

Setup

import { SuiClientGraphQLTransport } from '@onelabs/graphql-transport';
import { getFullnodeUrl, SuiClient } from '@onelabs/sui/client';

const client = new SuiClient({
	transport: new SuiClientGraphQLTransport({
		url: 'https://sui-testnet.mystenlabs.com/graphql',
		// When specified, the transport will fallback to JSON RPC for unsupported method and parameters
		fallbackFullNodeUrl: getFullnodeUrl('testnet'),
	}),
});

Limitations

Unsupported methods

The following methods are currently unsupported in SuiClientGraphQLTransport, and will either error, or fallback to the JSON RPC API if a fallbackFullNodeUrl is provided:

• subscribeTransaction
• subscribeEvents
• call
• getNetworkMetrics
• getMoveCallMetrics
• getAddressMetrics
• getEpochs
• dryRunTransactionBlock
• devInspectTransactionBlock
• executeTransactionBlock

Unsupported parameters

Some supported methods in SuiClientGraphQLTransport do not support the full set of parameters available in the JSON RPC API.

If an unsupported parameter is used, the request will error, or fallback to JSON RPC API if a fallbackFullNodeUrl is provided.

• getOwnedObjects:
  • missing the MatchAll, MatchAny, MatchNone, and Version filters
• queryEvents:
  • missing the MoveEventField, Module, TimeRange, All, Any, And, and Or filters

Unsupported fields

• queryTransactionBlocks, getTransactionBlock, and multiGetTransactionBlocks
  • missing messageVersion, eventsDigest, sharedObjects, unwrapped, wrapped, and unwrappedThenDeleted in effects
  • missing id for events
• getStakes and getStakesByIds
  • missing validatorAddress
• getLatestSuiSystemState
  • missing stakingPoolMappingsId, inactivePoolsId, pendingActiveValidatorsId, validatorCandidatesId
  • missing reportRecords on validators
• getCurrentEpoch
  • missing reportRecords on validators
• queryEvents
  • missing id for events
• getCheckpoint and getCheckpoints
  • missing checkpointCommitments
• getCurrentEpoch
  • missing epochTotalTransactions
• getDynamicFields
  • missing objectId, digest and version available for DynamicObject but not DynamicField

Performance

Some may require multiple requests to properly resolve:

• getDynamicFieldObject requires 2 requests
• queryTransactionBlocks, getTransactionBlock, and multiGetTransactionBlocks
  • may require additional requests to load all objectChanges, balanceChanges, dependencies and events
• getNormalizedMoveModule and getNormalizedMoveModulesByPage
  • may require additional requests to load all friends, functions, and structs
• getCheckpoint and getCheckpoints,
  • may require additional requests to load all transactionBlocks and validators
• getLatestSuiSystemState, getCurrentEpoch, getValidatorsApy and getCommitteeInfo:
  • may require additional requests to load all validators

Pagination

Page sizes and limits for paginated methods are based on the defaults and limits of the GraphQL API, so page sizes and limits may be different than those returned by the JSON RPC API
