Types ¶
type Option ¶
type Option func(*ValidationOptions)
Option Enables an 'Options pattern' approach
func WithContentAssertions ¶ added in v0.4.0
func WithContentAssertions() Option
WithContentAssertions enables checks for contentType, contentEncoding, etc
func WithCustomFormat ¶ added in v0.5.0
WithCustomFormat adds custom formats and their validators that checks for custom 'format' assertions When you add different validators with the same name, they will be overridden, and only the last registration will take effect.
func WithExistingOpts ¶ added in v0.4.4
func WithExistingOpts(options *ValidationOptions) Option
WithExistingOpts returns an Option that will copy the values from the supplied ValidationOptions instance
func WithFormatAssertions ¶ added in v0.4.0
func WithFormatAssertions() Option
WithFormatAssertions enables checks for 'format' assertions (such as date, date-time, uuid, etc)
func WithLogger ¶ added in v0.10.0
WithLogger sets the logger for validation debug/error output. If not set, logging is silent (nil logger is handled gracefully).
func WithOpenAPIMode ¶ added in v0.6.0
func WithOpenAPIMode() Option
WithOpenAPIMode enables OpenAPI-specific keyword validation (default: true)
func WithRegexCache ¶ added in v0.9.0
func WithRegexCache(regexCache RegexCache) Option
WithRegexCache assigns a cache for compiled regular expressions. A sync.Map should be sufficient for most use cases. It does not implement any cleanup
func WithRegexEngine ¶
func WithRegexEngine(engine jsonschema.RegexpEngine) Option
WithRegexEngine Assigns a custom regular-expression engine to be used during validation.
func WithScalarCoercion ¶ added in v0.6.0
func WithScalarCoercion() Option
WithScalarCoercion enables string to boolean/number coercion (Jackson-style)
func WithSchemaCache ¶ added in v0.8.0
func WithSchemaCache(cache cache.SchemaCache) Option
WithSchemaCache sets a custom cache implementation or disables caching if nil. Pass nil to disable schema caching and skip cache warming during validator initialization. The default cache is a thread-safe sync.Map wrapper.
func WithStrictIgnorePaths ¶ added in v0.10.0
WithStrictIgnorePaths sets JSONPath patterns for paths to exclude from strict validation. Patterns use glob syntax:
- * matches a single path segment
- ** matches any depth (zero or more segments)
- [*] matches any array index
- \* escapes a literal asterisk
Examples:
- "$.body.metadata.*" - any property under metadata
- "$.body.**.x-*" - any x-* property at any depth
- "$.headers.X-*" - any header starting with X-
func WithStrictIgnoredHeaders ¶ added in v0.10.0
WithStrictIgnoredHeaders replaces the default ignored headers list entirely. Use this to fully control which headers are ignored in strict mode. For the default list, see the strict package's DefaultIgnoredHeaders.
func WithStrictIgnoredHeadersExtra ¶ added in v0.10.0
WithStrictIgnoredHeadersExtra adds headers to the default ignored list. Unlike WithStrictIgnoredHeaders, this merges with the defaults rather than replacing them.
func WithStrictMode ¶ added in v0.10.0
func WithStrictMode() Option
WithStrictMode enables strict property validation. In strict mode, undeclared properties are reported as errors even when additionalProperties: true would normally allow them.
This is useful for API governance scenarios where you want to ensure clients only send properties that are explicitly documented in the OpenAPI specification.
func WithoutOpenAPIMode ¶ added in v0.6.0
func WithoutOpenAPIMode() Option
WithoutOpenAPIMode disables OpenAPI-specific keyword validation
func WithoutSecurityValidation ¶ added in v0.5.0
func WithoutSecurityValidation() Option
WithoutSecurityValidation disables security validation for request validation
type RegexCache ¶ added in v0.9.0
type RegexCache interface {
Load(key any) (value any, ok bool) // Get a compiled regex from the cache
Store(key, value any) // Set a compiled regex to the cache
}
RegexCache can be set to enable compiled regex caching. It can be just a sync.Map, or a custom implementation with possible cleanup.
Be aware that the cache should be thread safe
type ValidationOptions ¶
type ValidationOptions struct {
RegexEngine jsonschema.RegexpEngine
RegexCache RegexCache // Enable compiled regex caching
FormatAssertions bool
ContentAssertions bool
SecurityValidation bool
OpenAPIMode bool // Enable OpenAPI-specific vocabulary validation
AllowScalarCoercion bool // Enable string->boolean/number coercion
Formats map[string]func(v any) error
SchemaCache cache.SchemaCache // Optional cache for compiled schemas
Logger *slog.Logger // Logger for debug/error output (nil = silent)
// strict mode options - detect undeclared properties even when additionalProperties: true
StrictMode bool // Enable strict property validation
StrictIgnorePaths []string // Instance JSONPath patterns to exclude from strict checks
StrictIgnoredHeaders []string // Headers to always ignore in strict mode (nil = use defaults)
// contains filtered or unexported fields
}
ValidationOptions A container for validation configuration.
Generally fluent With... style functions are used to establish the desired behavior.
func NewValidationOptions ¶
func NewValidationOptions(opts ...Option) *ValidationOptions
NewValidationOptions creates a new ValidationOptions instance with default values.
func (*ValidationOptions) GetEffectiveStrictIgnoredHeaders ¶ added in v0.10.0
func (o *ValidationOptions) GetEffectiveStrictIgnoredHeaders() []string
GetEffectiveStrictIgnoredHeaders returns the list of headers to ignore based on configuration. Returns defaults if not configured, merged list if extra headers were added, or replaced list if headers were fully replaced.
