Types and validators that help describe the model of a Backstage Catalog
Classes
| Class | Description |
|---|---|
| CommonValidatorFunctions | Contains various helper validation and normalization functions that can be composed to form a Validator. |
| DefaultNamespaceEntityPolicy | Sets a default namespace if none was set. |
| FieldFormatEntityPolicy | Ensures that the format of individual fields of the entity envelope is valid. |
| GroupDefaultParentEntityPolicy | DefaultParentPolicy is an EntityPolicy that updates group entities with a parent of last resort. This ensures that, while we preserve any existing group hierarchies, we can guarantee that there is a single global root of the group hierarchy. |
| KubernetesValidatorFunctions | Contains validation functions that match the Kubernetes spec, usable to build a catalog that is compatible with those rule sets. |
| NoForeignRootFieldsEntityPolicy | Ensures that there are no foreign root fields in the entity. |
| SchemaValidEntityPolicy | Ensures that the entity spec is valid according to a schema. |
Functions
| Function | Description |
|---|---|
| entityEnvelopeSchemaValidator(schema) | Creates a validation function that takes some arbitrary data, and either returns that data cast to an EntityEnvelope (or the given subtype) if it matches that schema, or throws a describing the errors. |
| entityKindSchemaValidator(schema) | Creates a validation function that takes some arbitrary data, and either returns that data cast to a T if it matches that schema, or false if the schema apiVersion/kind didn't apply to that data, or throws a describing actual errors. |
| entitySchemaValidator(schema) | Creates a validation function that takes some arbitrary data, and either returns that data cast to an Entity (or the given subtype) if it matches that schema, or throws a describing the errors. |
| getCompoundEntityRef(entity) | Extracts the kind, namespace and name that form the compound entity ref triplet of the given entity. |
| getEntitySourceLocation(entity) | Returns the source code location of the Entity, to the extent that one exists. |
| isApiEntity(entity) | |
| isComponentEntity(entity) | |
| isDomainEntity(entity) | |
| isGroupEntity(entity) | |
| isLocationEntity(entity) | |
| isResourceEntity(entity) | |
| isSystemEntity(entity) | |
| isUserEntity(entity) | |
| makeValidator(overrides) | Creates a Validators object from overrides, with default values taken from KubernetesValidatorFunctions |
| parseEntityRef(ref, context) | Parses an entity reference, either on string or compound form, and returns a structure with a name, and optional kind and namespace. |
| parseLocationRef(ref) | Parses a string form location reference. |
| stringifyEntityRef(ref) | Takes an entity or entity name/reference, and returns the string form of an entity ref. |
| stringifyLocationRef(ref) | Turns a location ref into its string form. |
Interfaces

| LocationEntityV1alpha1 | Backstage catalog Location kind Entity. |
| ResourceEntityV1alpha1 | Backstage catalog Resource kind Entity. Represents infrastructure required to operate Components. |
| SystemEntityV1alpha1 | Backstage catalog System kind Entity. Systems group Components, Resources and APIs together. |
| UserEntityV1alpha1 | Backstage catalog User kind Entity. |
