Gives you full control over HTTP request/response from within an action

New

Web actions



Another way to invoke an action is via our newest web action capabilities. Those OpenWhisk actions quickly enable you to build web based applications. Allowing backend logic which your web application can access anonymously without requiring an OpenWhisk authentication key. It is up to the action developer to

Integration with

New

Allows OpenWhisk to work with today’s stream-based applications; stream data to/from OpenWhisk and leverage PubNub BLOCKS for lightweight compute in the network.

Bringing OpenWhisk to Realtime Applications




Vehicle DispatchPubNub Blocks → OpenWhisk

PubNub Blocks filters geo data and routes to OpenWhisk for

computation. OpenWhisk runs business logic and M.L. and broadcasts back to PubNub

listeners on end-devices.

NewSample use-cases…

Disaster AlertsOpenWhisk → PubNub

OpenWhisk detects weather anomalies and and broadcasts to PubNub listeners on end-devices

for real-time disaster alerts.

Social Chat AppPubNub → Watson + OpenWhisk

PubNub filters chat messages through a PubNub Watson

Translator Block, and offloads audience analysis to OpenWhisk for

async post-processing.



Sample…

Clone and configure PubNub’s OpenWhisk Block at pubnub.com/openwhisk

{ “Openwhisk”: { “triggerName”: “hello_world” “payload”: {“message”: “Hello From PubNub BLOCKS!”, “publishTime”: 1492747834095 } } }

function main(params) { var dateNow = + new Date();

return { message: params.message, time_to_publish: dateNow - params.publishTime } }

{ “message”: “Hello From PubNub Blocks!”, “time_to_publish”: 15 }
