The F5 BIG-IP Application Services 3 Extension (referred to as BIG-IP AS3) is a flexible, low-overhead mechanism for managing application-specific configurations on a BIG-IP system. BIG-IP AS3 uses a declarative model, meaning you provide a JSON declaration rather than a set of imperative commands. The declaration represents the configuration which BIG-IP AS3 is responsible for creating on a BIG-IP system. BIG-IP AS3 is well-defined according to the rules of JSON Schema, and declarations validate according to JSON Schema. BIG-IP AS3 accepts declaration updates via REST (push), reference (pull), or CLI (flat file editing).
You can use Microsoft Visual Studio Code to validate your declarations, see Validating a Declaration for information.
