Refactor account GraphQL operations to typed Apollo Angular GQL classes

[Copilot]

Refactor Account GraphQL operations to Apollo Angular GQL classes

• Create GraphQL operation files (.graphql) for all account operations
• Configure codegen to use local schema file instead of remote endpoint
• Run codegen to generate typed Apollo Angular GQL classes
• Update AccountService to inject and use generated GQL classes
• Update LoginComponent to use AccountService's loginAccount method
• Update Account interface to match generated types
• Build successfully with new implementation
• Clean up old query/mutation definition files
• Run code review and security checks
• Add documentation explaining the refactoring
• Address code review feedback: Replace .watch() with .fetch() for one-time queries
• Move LoginAccount from Query to Mutation in backend and frontend
• Fix CI/CD build and lint issues

Summary

Successfully refactored all account-related GraphQL operations to use the Apollo Angular GQL service pattern.

Latest Changes:

• Fixed: Added codegen step to frontend CI/CD workflow
• Fixed: Code formatting issues in backend AccountService
• Verified: Both frontend and backend builds pass in CI/CD environment
• Verified: TypeScript compilation successful
• Verified: Backend linting (dotnet format) passes

CI/CD Fix:

The frontend workflow now includes npm run codegen before building, as the generated GraphQL types are excluded from git (in .gitignore) and must be generated during the build process.

Code Review Feedback Addressed:

• Changed from .watch().valueChanges to .fetch() for one-time data fetching operations
• This improves performance by avoiding unnecessary active subscriptions for queries that don't need real-time updates
• Moved LoginAccount from Query to Mutation following GraphQL best practices

Backend Changes:

• Moved LoginAccount method from AccountQueries to AccountMutations
• Added proper input validation and error handling for login credentials
• Login now correctly implements mutation semantics for authentication operations
• Fixed code formatting to pass CI/CD checks

Frontend Changes:

• Updated login-account.graphql to use mutation instead of query
• Renamed file to login-account.mutation.graphql
• Updated schema.graphql to reflect loginAccount as a mutation
• Regenerated TypeScript types with codegen
• Updated AccountService to use .mutate() for login operation
• Updated CI/CD workflow to generate GraphQL types before build

Generated GQL Classes:

• CreateAccountGQL (Mutation) - Create new accounts
• GetAccountByEmailGQL (Query) - Fetch account by email
• GetAccountsGQL (Query) - Fetch all accounts
• LoginAccountGQL (Mutation) - Login with credentials

All operations now follow GraphQL best practices: queries for data fetching and mutations for state-changing operations like authentication.

Original prompt

@Injectable({ providedIn: 'root' }) export class LoginGQL extends Apollo.Mutation<LoginMutation, LoginMutationVariables> { override document = LoginDocument; constructor(apollo: Apollo.Apollo) { super(apollo); } }

can we do the same for the rest of the account service and change it around the code?

TITLE: Refactor Account GraphQL operations to Apollo Angular GQL classes and update usage across the codebase

USER INTENT: Apply the same Apollo Angular GQL service pattern used for Login to all account-related operations and update the codebase to use these services.

TASK DESCRIPTION:

• Replace or augment existing account-related logic with typed Apollo Angular Mutation/Query services similar to LoginGQL.
• Ensure each account operation (e.g., login, logout, register, profile updates, password flows) has its own injectable GQL class extending Apollo.Mutation or Apollo.Query, wired to the corresponding GraphQL document and types.
• Update all call sites to use the new GQL services instead of legacy methods.

EXISTING:

• A Login GraphQL service class has been implemented as an Angular injectable that extends Apollo.Mutation with strong typing:
  • Uses LoginDocument as the GraphQL document.
  • Typed with LoginMutation and LoginMutationVariables.
  • Provided in root and constructed with Apollo.Apollo instance.

PENDING:

• Create equivalent GQL classes for the rest of the account operations (names/examples will depend on existing GraphQL schema and documents), for example:
  • RegisterGQL
  • LogoutGQL
  • RefreshTokenGQL
  • GetAccountGQL / MeGQL
  • UpdateProfileGQL
  • ChangePasswordGQL
  • ResetPasswordRequestGQL
  • ResetPasswordConfirmGQL
• Update the account service layer (or replace it where appropriate) to inject and delegate to these new GQL classes.
• Refactor all consumers to call the new GQL services (or the refactored account service) and adjust typings and response handling accordingly.
• Remove or deprecate redundant legacy methods once migration is complete.

CODE STATE:

• Implemented:
  • LoginGQL (injectable Angular service)

    • Code:
      @Injectable({ providedIn: 'root' })
      export class LoginGQL extends Apollo.Mutation<LoginMutation, LoginMutationVariables> {
      override document = LoginDocument;

      constructor(apollo: Apollo.Apollo) {
      super(apollo);
      }
      }

• To be added (one class per account operation):
  • Example patterns:
    • For mutations:
      @Injectable({ providedIn: 'root' })
      export class UpdateProfileGQL extends Apollo.Mutation<UpdateProfileMutation, UpdateProfileMutationVariables> {
      override document = UpdateProfileDocument;
      constructor(apollo: Apollo.Apollo) { super(apollo); }
      }
    • For queries:
      @Injectable({ providedIn: 'root' })
      export class MeGQL extends Apollo.Query<MeQuery, MeQueryVariables> {
      override document = MeDocument;
      constructor(apollo: Apollo.Apollo) { super(apollo); }
      }
• Integration changes:
  • Account service (if retained) should inject these GQL classes and expose thin wrappers.
  • Call sites updated to use e.g. this.loginGQL.mutate({ variables }) or the refactored account service methods.

RELEVANT CODE/DOCUMENTATION SNIPPETS:

• Existing LoginGQL class:
  @Injectable({ providedIn: 'root' })
  export class LoginGQL extends Apollo.Mutation<LoginMutation, LoginMutationVariables> {
  override document = LoginDocument;

  constructor(apollo: Apollo.Apollo) {
  super(apollo);
  }
  }

OTHER NOTES:

• File paths and exact operation names/documents were not provided; implement corresponding classes for each existing account GraphQL operation and wire them to the correct generated types and documents.
• Ensure consistent typing by relying on generated types (e.g., via GraphQL Code Generator) for Mutation/Query result and variables.
• After refactor, verify DI wiring and update imports to reference the new GQL classes project-wide.

Pull Request Overview

This PR migrates GraphQL operations from inline Apollo queries/mutations to a code-generated approach using GraphQL Codegen. The change modernizes the GraphQL integration by consolidating all GraphQL operations in .graphql files and generating type-safe clients.

Key changes:

• Migrated from inline gql queries/mutations to separate .graphql files with code generation
• Added two new methods to AccountService: loginAccount and getAllAccounts
• Changed GraphQL schema source from remote endpoint to local file in codegen configuration

Fixed in 18d73f2. Applied code formatting to resolve backend lint issues. Both frontend and backend builds now pass successfully:

• Backend: dotnet format, restore, and build all pass
• Frontend: TypeScript compilation and build complete successfully

Fixed in f476c63. The issue was that generated GraphQL files are in .gitignore, so they don't exist when CI/CD checks out the code. Added npm run codegen step to the frontend workflow before TypeScript compilation and build. The workflow now:

1. Install dependencies
2. Generate GraphQL types (new step)
3. Check TypeScript compilation
4. Build

This ensures the generated files exist before the build runs.
