  // Create a JSON response

  // Use path parameters

});

Installation

API details

The package exposes one function which accepts another function and returns a valid OpenWhisk action. This function will be invoked during action initialisation and is called with the action instance.

const routes = require('openwhisk-routes');

exports.main = routes((action) => {
  // Defined your routes
  action.get('/', (request, response, next) => {
    next();
  })
}

Action

action is derived from the routes npm package.
