Swagger Express Middleware

swagger-express-mw is an abandoned CommonJS middleware for integrating Swagger (OpenAPI 2.0) definitions with Express applications. It functions primarily as a wrapper around the `swagger-node-runner` package, handling the loading and application of Swagger definitions to an Express server. The package's current stable version is 0.7.0, released in January 2017. Both `swagger-express-mw` and its core dependency `swagger-node-runner` have not seen active development or releases in over seven years, indicating a lack of maintenance. While it simplifies the setup of Swagger-driven APIs by automating routing and validation based on a YAML or JSON definition, its age means it only supports Swagger 2.0 and is not compatible with modern OpenAPI 3.x specifications. There are several forks like `swagger-express-mw-fork` and `swagger-node-runner-fixed` attempting to address some of the issues or update dependencies for newer Node.js versions.
