Optional
callbackIf supplied, a callback will be called immediately upon retrieval of an end point value.
The three arguments supplied will be the value of the payload
(according to resultType
), the type of the payload (whether it is
a normal "value" or a "property" name), and a full payload object
(with all resultType
s).
Optional
evalScript evaluation method.
safe
: In browser, it will use a minimal scripting engine which doesn't
use eval
or Function
and satisfies Content Security Policy. In NodeJS,
it has no effect and is equivalent to native as scripting is safe there.
native
: uses the native scripting capabilities. i.e. unsafe eval
or
Function
in browser and vm.Script
in nodejs.
true
: Same as 'safe'
false
: Disable Javascript executions in path string. Same as preventEval: true
in previous versions.
callback [ (code, context) => value]
: A custom implementation which is called
with code
and context
as arguments to return the evaluated value.
class
: A class similar to nodejs vm.Script. It will be created with code
as constructor argument and the code
is evaluated by calling runInNewContext
with context
.
Optional
flattenWhether the returned array of results will be flattened to a single dimension array.
Optional
ignoreIgnore errors while evaluating JSONPath expression.
true
: Don't break entire search if an error occurs while evaluating JSONPath expression on one key/value pair.
false
: Break entire search if an error occurs while evaluating JSONPath expression on one key/value pair.
The JSON object to evaluate (whether of null, boolean, number, string, object, or array type).
Optional
otherIn the current absence of JSON Schema support,
one can determine types beyond the built-in types by adding the
perator @other()
at the end of one's query.
If such a path is encountered, the otherTypeCallback
will be invoked
with the value of the item, its path, its parent, and its parent's
property name, and it should return a boolean indicating whether the
supplied value belongs to the "other" type or not (or it may handle
transformations and return false).
Optional
parentIn the event that a query could be made to return the root node, this allows the parent of that root node to be returned within results.
Optional
parentIn the event that a query could be made to return the root node, this allows the parentProperty of that root node to be returned within results.
The JSONPath expression as a (normalized or unnormalized) string or array.
Optional
resultCan be case-insensitive form of "value", "path", "pointer", "parent", or "parentProperty" to determine respectively whether to return results as the values of the found items, as their absolute paths, as JSON Pointers to the absolute paths, as their parent objects, or as their parent's property name.
If set to "all", all of these types will be returned on an object with the type as key name.
Optional
sandboxKey-value map of variables to be available to code evaluations such as filtering expressions. (Note that the current path and value will also be available to those expressions; see the Syntax section for details.)
Optional
wrapWhether or not to wrap the results in an array.
If wrap is set to false, and no results are found, undefined will be returned (as opposed to an empty array when wrap is set to true).
If wrap is set to false and a single non-array result is found, that result will be the only item returned (not within an array).
An array will still be returned if multiple results are found, however. To avoid ambiguities (in the case where it is necessary to distinguish between a result which is a failure and one which is an empty array), it is recommended to switch the default to false.
If this is supplied as false, one may call the evaluate method manually.
