Import: json

The json import enables a Sentinel policy to parse and access a JSON document.

json.unmarshal(obj)

Unmarshals the JSON object obj into a native Sentinel structure.

All native JSON types can be represented perfectly as Sentinel native types.

// Typically the input for this would come from an external source.config = json.unmarshal("{ \"foo\": 42 }")config.foo // 42config.bar // undefined (as usual for accessing a non-existent map key)

json.marshal(obj)

Marshals the Sentinel object obj into a JSON object encoded as a string.

Sentinel's functions cannot be natively encoded, and will cause an error if it is present within the provided object.

Sentinel's undefined cannot be natively encoded as JSON. If undefined is supplied directly to marshal, it will return undefined. If undefined is present within any map or list within the provided object, the associated element will be removed prior to performing the JSON encoding.
