node-red-contrib-jexl
node-red node to parse and evaluate an expression against a context using jexl
What does it do?
The jexl node expects a msg.payload that contains a valid jexl expression, e.g.
(data.someprop + 2) > 42 ? "cannot be" : "this is right"
It also expects some data in the msg.context property. The expression is parsed and evaluated against this data, e.g.
This would result in this string: this is right in msg.payload.
Ideas to improve this node
- set the input property name for payload / context
- allow to add operators or transforms by passing in more message parts, that contain javascript code
- allow to set xml / yaml transforms to run these formats with the node.
