The module is now git.unbound.se/shiny/presenter. The API is unchanged. Tags up to v0.3.7 declare gitea.unbound.se/shiny/presenter and stay resolvable through that alias. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Kko4x3MYEcWMMdkx12WpBa

## Library Information
|
|
|
|
### Purpose
|
|
|
|
Provides a standardized GraphQL error presenter that handles coded errors across all microservices. Converts internal error codes to GraphQL error extensions.
|
|
|
|
### Usage
|
|
|
|
```go
|
|
import "git.unbound.se/shiny/presenter"
|
|
|
|
// Create error presenter with valid codes and entities
|
|
errorPresenter := presenter.New(logger, validCodes, validEntities, internalErrorCode)
|
|
|
|
// Use in gqlgen server config
|
|
srv := handler.NewDefaultServer(generated.NewExecutableSchema(cfg))
|
|
srv.SetErrorPresenter(errorPresenter)
|
|
```
|
|
|
|
### Key Types
|
|
|
|
- `CodedError` - Error type with code, entity, and params
|
|
- `Code` - Error code type
|
|
- `Entity` - Error entity type
|
|
|
|
### Error Extensions
|
|
|
|
Errors are presented with extensions:
|
|
- `code` - The error code (mapped to valid codes or internal error)
|
|
- `errorEntity` - The entity related to the error (optional)
|
|
- `params` - Additional error parameters (optional)
