node-red-contrib-unsafe-function 0.3.0

The fast and furious version of function nodes

npm install node-red-contrib-unsafe-function

The fast and furious version of function nodes.

Uses require-from-string instead of executing the function inside a vm.

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 (like calling require('fs') and its operations).

Additional Features

NODE_RED_CONTRIB_UNSAFE_FUNCTION_ASYNC_SEND, NODE_RED_CONTRIB_UNSAFE_FUNCTION_ASYNC_RECEIVE - 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.
