node-red-contrib-map

This is a Node-RED plugin that provides a new mappings category with the following nodes:

• map: Allows for mapping a configurable property from an input message to a configurable property on the output message, based on the configured mappings. For example, given an input message containing topic:deviceId, this node can add add a message property topicName:deviceName.
• set: Allows for adding a configurable property based on a specific mapping in the configured mappings. For example, this allows for adding a property topic:deviceId for a given device to any input message.
• switch: Allows for switching between one or more outputs based on configured mappings. For example, given an input message containing topic:deviceId, you can define separate outputs for device id deviceId1 and deviceId2.

All mappings are configured through a configuration node, meaning that each of the nodes listed above can re-use a pre-configured mapping. For example, you can have one configuration that maps input device id's to device names, and another configuration that maps device names to output device id's.
