Actions in Rules

Actions define what a rule does. Use constants to make it easier to perform any action.

Actions define the way rules change an app’s JSON files. Valid actions are:

• delete: Delete a node in the document.
• put: Add a node to an object.
• set: Set the value of an existing node in the document.
• add: Add an element to an array
• eval: Evaluate a specified expression and assign results to a variable.
• replace: Search and replace a text string globally.

Each action has a path attribute, which is a JsonPath that points to a node in the document. JsonPath is to JSON as XPath is to XML. Practice it in the Jayway JsonPath Evaluator.

Actions can be conditionally applied to a document. Set the condition on a set of actions or on a collection of actions.
