Overview ¶
Package astnormalization helps to transform parsed GraphQL AST's into a easier to use structure.
Example ¶
This examples shows how the normalization package helps "simplifying" a GraphQL AST.
Input:
subscription sub {
... multipleSubscriptions
... on Subscription {
newMessage {
body
sender
}
}
}
fragment newMessageFields on Message {
body: body
sender
... on Body {
body
}
}
fragment multipleSubscriptions on Subscription {
newMessage {
body
sender
}
newMessage {
... newMessageFields
}
newMessage {
body
body
sender
}
... on Subscription {
newMessage {
body
sender
}
}
disallowedSecondRootField
}
Output:
subscription sub {
newMessage {
body
sender
}
disallowedSecondRootField
}
fragment newMessageFields on Message {
body
sender
}
fragment multipleSubscriptions on Subscription {
newMessage {
body
sender
}
disallowedSecondRootField
}

Functions ¶
func NormalizeDefinition ¶
func NormalizeDefinition(definition *ast.Document, report *operationreport.Report)
NormalizeDefinition creates a default DefinitionNormalizer and applies all rules to a given AST In case you're using DefinitionNormalizer in a hot path you shouldn't be using this function. Create a new DefinitionNormalizer using NewDefinitionNormalizer() instead and re-use it.
func NormalizeNamedOperation ¶
func NormalizeNamedOperation(operation, definition *ast.Document, operationName []byte, report *operationreport.Report)
func NormalizeOperation ¶
func NormalizeOperation(operation, definition *ast.Document, report *operationreport.Report)
NormalizeOperation creates a default Normalizer and applies all rules to a given AST In case you're using OperationNormalizer in a hot path you shouldn't be using this function. Create a new OperationNormalizer using NewNormalizer() instead and re-use it.
func NormalizeSubgraphSDL ¶
func NormalizeSubgraphSDL(definition *ast.Document, report *operationreport.Report)
Types ¶
type DefinitionNormalizer ¶
type DefinitionNormalizer struct {
// contains filtered or unexported fields
}
DefinitionNormalizer walks a given AST and applies all registered rules
func NewDefinitionNormalizer ¶
func NewDefinitionNormalizer() *DefinitionNormalizer
NewDefinitionNormalizer creates a new DefinitionNormalizer and sets up all default rules
func NewSubgraphDefinitionNormalizer ¶
func NewSubgraphDefinitionNormalizer() *DefinitionNormalizer
func (*DefinitionNormalizer) NormalizeDefinition ¶
func (o *DefinitionNormalizer) NormalizeDefinition(definition *ast.Document, report *operationreport.Report)
NormalizeDefinition applies all registered rules to the AST
type Depth ¶
type Depth struct {
SpreadRef int
Depth int
SpreadName ast.ByteSlice
// contains filtered or unexported fields
}
Depth holds all necessary information to understand the Depth of a Fragment Node
type FragmentDefinitionRemoval ¶
type FragmentDefinitionRemoval struct {
}
type FragmentSpreadDepth ¶
type FragmentSpreadDepth struct {
// contains filtered or unexported fields
}
FragmentSpreadDepth is a helper for nested Fragments to calculate the actual depth of a Fragment Node
func (*FragmentSpreadDepth) Get ¶
func (r *FragmentSpreadDepth) Get(operation, definition *ast.Document, report *operationreport.Report, depths *Depths)
Get returns all FragmentSpread Depths for a given AST
type OperationNormalizer ¶
type OperationNormalizer struct {
// contains filtered or unexported fields
}
OperationNormalizer walks a given AST and applies all registered rules
func NewNormalizer ¶
func NewNormalizer(removeFragmentDefinitions, extractVariables bool) *OperationNormalizer
NewNormalizer creates a new OperationNormalizer and sets up all default rules
func NewWithOpts ¶
func NewWithOpts(opts ...Option) *OperationNormalizer
NewWithOpts creates a new OperationNormalizer with Options
func (*OperationNormalizer) NormalizeNamedOperation ¶
func (o *OperationNormalizer) NormalizeNamedOperation(operation, definition *ast.Document, operationName []byte, report *operationreport.Report)
NormalizeNamedOperation applies all registered rules to one specific named operation in the AST
func (*OperationNormalizer) NormalizeOperation ¶
func (o *OperationNormalizer) NormalizeOperation(operation, definition *ast.Document, report *operationreport.Report)
NormalizeOperation applies all registered rules to the AST
type Option ¶
type Option func(options *options)
func WithExtractVariables ¶
func WithExtractVariables() Option
func WithNormalizeDefinition ¶
func WithNormalizeDefinition() Option
func WithRemoveFragmentDefinitions ¶
func WithRemoveFragmentDefinitions() Option
func WithRemoveUnusedVariables ¶
func WithRemoveUnusedVariables() Option
type SubgraphSDLNormalizer ¶
type SubgraphSDLNormalizer struct {
// contains filtered or unexported fields
}
func NewSubgraphSDLNormalizer ¶
func NewSubgraphSDLNormalizer() *SubgraphSDLNormalizer
func (*SubgraphSDLNormalizer) NormalizeSubgraphSDL ¶
func (s *SubgraphSDLNormalizer) NormalizeSubgraphSDL(definition *ast.Document, report *operationreport.Report)
