Store data in Node Red memory

Sometimes information need to be stored (in Node-RED memory), to have that information available:

• At a later moment in time.
• In another node.

Node-RED offers 3 locations (in Node-RED memory) where the information can be stored:

• Node: for information that needs to be available only to the node that stored the value
• Flow: for information that needs to be available for all nodes on the same flow (i.e. same tabsheet in the flow editor)
• Global: for information that needs to be available for all nodes

The following animation shows how to accomplish these steps:

1. Create a property 'myFlow' on flow memory with value 'flowValue'.
2. Create a property 'myGlobal' on flow memory with value 'globalValue'.
3. Create a property 'myNode' on flow memory with value 'nodeValue'.

Remark: the node memory is also called 'context'.
