swaggerUI -> Where is your swagger-ui?
swaggerURL -> Path to use for swagger ui web interface.
swaggerJSON -> Path to use for swagger ui JSON.
basePath -> The basePath for swagger.js
info -> Metadata about the API
apis -> Define your api array.
middleware -> Function before response.
var swagger = require('swagger-express');
app.configure(function(){
...
app.use(swagger.init(app, {
apiVersion: '1.0',
swaggerVersion: '1.0',
swaggerURL: '/swagger',
swaggerJSON: '/api-docs.json',
swaggerUI: './public/swagger/',
basePath: 'http://localhost:3000',
info: {
title: 'swagger-express sample app',
description: 'Swagger + Express = {swagger-express}'
},
apis: ['./api.js', './api.yml'],
middleware: function(req, res){}
}));
app.use(app.router);
...
});
