Router for Alexa Skill Kit SDK v2
When you need more than you have.
This library extends the routing in Alexa Skill Kit SDK v2. It has several simple methods to manage the process of request handling.
In two words, it tests canHandle() function of each request handler - does the same as built-in ASk SDK routing, but with methods to go to the next suitable handler or restart routing.
npm i --save ask-sdk-router
Init Router with object containing all your request handlers. Very close to way you did it in skillBuilder.addRequestHandlers(), but you have to wrap all the items in one object.
const Router = ; const router = // list your request handlers here like you did it in skillBuilder.addRequestHandlers() SessionEndedRequestHandler CancelIntentHandler HelpIntentHandler FallbackHandler // also you can use another syntax for the object 'CrazyJump': CrazyJumpHandler 10: TenthHandler; exportshandler = skillBuilder ;
Now you can use the router in any part of your skill! The router is stored in request attributes with
const router = handlerInputattributesManagerrouter;return await routernexthandlerInput;
What router can do?
Go to next suitable request handler
return await routernexthandlerInput;
Go to first suitable request handler from beginning
return await router;
Jump to selected request handler (from v2.0.0)
// jump to CancelIntentHandler without canHandle testreturn await router; // jump to CrazyJumpHandler only if canHandle returns true, otherwise jumpTo() will return falsereturn await router;
