Legacy Middleware

Using Legacy Middleware for Express or third party servers like Node.js 'http'

Legacy Middleware#

With the iopa-connect package, IOPA servers can also call legacy Node HTTP middleware in the same chain with app.use( function(req,res){ ... } ). All the mapping between the IOPA property dictionary and the NODE req, res dictionaries done automatically without duplication of data.

Legacy Servers#

Many reference servers are written from the ground up and available already for IOPA including HTTP, CoAP, MQTT, UPNP, TCP, UDP, Stub Testing, WebKit-DarwinJavaScriptBridge, Chakra-WindowsJavasScriptBridge etc.. However, in Node.js, existing servers that create a req res object (such as the built in http library) can also be used with a simple require('iopa-connect') bridge; similar bridges are available for node-coap, node-slack, azure-functions etc.
