The fast and furious version of function nodes
The fast and furious version of function nodes.
The implementation sticks to the api of the standard function nodes,
so if your code worked on a standard function node it should also work on
unsafe-function (only faster!).
unsafe-function does not run inside a vm and therefore may do unsafe operations
require('fs') and its operations).
Set these environment variables in order to make the sending\receiving of messages asynchronous.
The current behavior of node-red is that sending a message pauses until all the following nodes
in the flow finish handling the sent message (unless they specifically do it asynchronously).
For more information, see issue 833.
NODE_RED_CONTRIB_UNSAFE_FUNCTION_PROFILING: Set this environment variable to show
for each node a status message with basic profiling information: how many messages
were handled and what's the total\max execution time.
