6. GraphQL Schema

[mrserverless]

• 6.1 Define graphql/schema.graphql
  • String-based types (Money as object, DateTime as string)
  • Enum types (AccountType, TransactionType, ConsentStatus, BalanceType)
  • Object types (Account, Balance, Transaction, Consent)
  • Query type (account, accounts, balance, transactions, consent)
  • Input types (TransactionHistoryInput for filtering)
• 6.2 Configure custom scalar types in gqlgen.yml
  • Simplified configuration without custom scalars for MVP
• 6.3 Map GraphQL types to Go models
  • Account → models.Account
  • Transaction → models.Transaction
  • Balance → models.Balance
  • Consent → models.Consent
