A CLI tool to identify differences between Swagger/OpenAPI specs.

• NPM 2.x or higher (tested using 2.x, 3.x and 5x)

Installation

Install the tool using NPM:

Usage

Invoke the tool with two paths to Swagger/OpenAPI files in order to find differences between them, these paths can either be paths to the specs in the local filesystem or URLs to the specs. The Open API specs should be in JSON format.
