Application Services 3 Extension (referred to as AS3 Extension or more often simply AS3) is a flexible, low-overhead mechanism for managing application-specific configurations on a BIG-IP system. AS3 uses a declarative model, meaning you provide a JSON declaration rather than a set of imperative commands. The declaration represents the configuration which AS3 is responsible for creating on a BIG-IP system. AS3 is well-defined according to the rules of JSON Schema, and declarations validate according to JSON Schema. 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.
