How to implement in a easy way a custom platform? about jovo-framework HOT 1 CLOSED

There are 2 ways to approach this:
- Write code that maps the vonage request/response to a Jovo CorePlatform-derived request response. You are responsible for converting between the two usually in the server.express.ts file
- Write your own implementation that requires you to create: Vonage.ts, VonageDevice.ts, VonagePlatform.ts, VonageRequest.ts, VonageResponse.ts and VonageUser.ts.

The best way to do option 2 is to look at the Facebook and Alexa platforms

Option 2 is the most powerful. If vonage uses HTTPS endpoint and the body of the request is the request object that you want to use, you can use the existing ExpressJs class.

Important parts using Facebook as an example:
- FacebookMessangerRequest - defines the structure of the request JSON and get/set functions map to properties on that object. Pay attention to getRequestId, getInputText
- FacebookMessangerResponse - defines structure of output JSON
- FacebookMessangerUser - id property maps to property on this.jovo.$request which is set as part of call to ExpressJs
- FacebookMessangerPlatform - ties everything together. Pay attention to isRequestRelated as that is how Jovo knows to pick a platform based on the request JSON. All it does is pick a few properties from the request that will identify this JSON as belonging to one platform instead of another. Similarly, there is a isResponseRelated.
