Cardano GraphQL - Util

Changelog

5.0.0 (2021-07-14)

Compatible with:

• cardano-node: 1.27.0
• cardano-db-sync: 10.0.1 - Note: The database must be recreated using the new version.
• hasura/graphql-engine: 1.3.3

⚠ BREAKING CHANGES

• Asset.assetName and Asset.assetId are now typed as Hex, as the relationship from Assets to TokenMints needed to be established using the underlying table, where assetId is not present.

• Configuration of the asset metadata fetching is now a single value. POLLING_INTERVAL_METADATA_SYNC_INITIAL and POLLING_INTERVAL_METADATA_SYNC_ONGOING are replaced by ASSET_METADATA_UPDATE_INTERVAL, which is the number of seconds before the service checks the registry for updates.

• AssetSupply.total is now an optional field, and can return null.

• Transaction.metadata is now JSON type, not JSONObject

  • Despite the name, JSONObject was mapped to the underlying JSON resolver as a workaround to avoid breaking changes.

• The fields previously modelled on Token have been nested under Token.asset

• tokens and tokens_aggregate have been removed in favour of assets and assets_aggregate

• Asset properties nested under PaymentAddress.assets are now under PaymentAddress.assets.asset

• Block.merkleRoot removed, as no longer part of cardano-db-sync schema. (8b3b718)

Features

• Replaces the use of cardano-cli with Ogmios for interacting with the node using JSON-WSP, and implements the convenient cardano-node-ogmios Docker image as a drop-in replacement for the cardano-node image.
• Sync assets using chain-sync protocol via Ogmios (784509e)
• tokenMints and tokenMints_aggregate queries (f803b94)
• add query complexity validations (24a14a9),
• add default query complexity calculations with arguments (b16c77d)
• implement complexity in resolvers (5664a55)
• use cardano-node config for lastConfiguredMajorVersion (5a621c2), closes #454
• add Epoch_bool_exp.startedAt (4cc580a)
• add TransactionOutput_bool_exp.index (34d5438)
• allow ordering of assets by token mint count (cfbb039)
• Asset metadata decimals (082f509)

Bug Fixes

• improve startup robustness (7054a59)
  • The GraphQL server is now delayed until all modules are initialized, and running. If cardano-db-sync reboots, all modules are shutdown, and restarted and therefore links the server availability with a fully initialized stack.
• Add order_by to asset query (5848c24)
• Asset_bool_exp.tokenMints (7616a49)
• assetFingerprint bug when no assetName present (9a61d91), closes #487
• await all promises in shutdown function (3d7ef11)
• await CardanoNodeClient init before starting server (f33f6aa)
• cardanoDbSyncMeta.initialized during startup (d6649cf)
• casing on invalid hereafter in GraphQL schema (854ec4a), closes #390
• Copy cardano-node config into Docker image (4bf4866)
• default metadata server URI (2a98055)
• disable CORS in Hasura graphql-engine (4499422), closes #392
• Ensure DB is in current era before completing HasuraClient initialization (0d43abc)
• guards on missing current epoch row (6204c96)
• log all error messages during service startup, not just HostDoesNotExist (c81aad8)
• memory leak in Hasura GraphQL client (3c8511d)
• move current era check to be lazy operation (7830c91)
• move graphql-engine option under serve command (f76e944)
• policyId comparison expression type (99318cc), closes #485
• remove promise chaining cycle (8b55ca0), closes #459
• Reorder logging arguments based on Bunyan interface (46b26a0)
• Restore protocol params fetcher init (e86fc1a)
• scoping on package (82e2040)
• submitTransaction error mapping (3629725)
