This little command line tool allows you to serve the current directory's contents (which are presumably Swagger or OpenAPI docs in either YAML or JSON) alongside swagger-ui.
You can use the location bar in the app next to the "Explore" button and input
the name of a local file (i.e. api.yaml) to load that file (via it's relative
localhost URL) into Swagger UI.
Click "Explore" and you should see the documentation of your API loaded below.
$ npm i -g WileyLabs/serve-swagger-ui
$ serve-swagger-ui
Or if you need a custom directory and/or port number:
serve-swagger-ui api/ -p 2020
To use it as a Docker container:
$ docker build -t serve-swagger-ui .
Now you can serve files from your local folder:
$ docker run -it -v $PWD:/specs -p 3000:3000 serve-swagger-ui
