type ASTLookup ¶

type ASTLookup interface {
	LookupType(ast.Type) ast.TypeDefinition
}

ASTLookup must lookup types in the original schema.

type Model ¶

type Model struct {
	// contains filtered or unexported fields
}

Model defines the linkage between a GraphQL schema and a codebase. Schema types are bound to Go types, for example:

• Object type bound to Go struct or interface type
• Array type bound to Go struct or channel type
• Any type bound to Go channel(s) indicating mutable real-time value

This representation yields Resolver implementations that emit Go code to resolve at runtime.

func BuildModel(
	rootSchema *ast.ObjectDefinition,
	astLookup ASTLookup,
	rootResolverType gtypes.Type,
) (*Model, error)

func (m *Model) GenerateResolverFile() (*gast.File, error)

func (m *Model) GetAllResolvers() []Resolver

func (m *Model) GetImportPaths() []string

func (m *Model) GetRootResolver() Resolver

type Resolver ¶

type Resolver interface {
	// GetName returns the resolver name.
	// This is typically the function name.
	GetName() string
	// GenerateGoASTDecls generates Go declarations to fulfill the resolver.
	GenerateGoASTDecls() ([]gast.Decl, error)
	// GenerateGoASTRef generates the Go statements to call the resolver.
	GenerateGoASTRef() ([]gast.Stmt, error)
}

Resolver implements resolution of a piece of the schema with Go code.
