Conditional block

Purpose:

Compare data. Outputs 'true', if the condition is met. The following comparisons can be done:

type Description
eq* Equals
ne* Not equals
gt Greater than
gte Greater than or equal
lt Lower than
lte Lower than or equal
  • The eq and ne will allow a undefined to be the same as a null

Input:

  • Fist value
    Can be any type of data. Is forgotten when output has been provided.

  • Secound value
    Can be any type of data. Is forgotten when output has been provided.

Output:

  • Boolean
    Only outputs 'true' if condition has been met. Will only output, when both values are set.

Example:

Often used to create 'if-else' statements. Works very well with DateTime. Here we want to do one thing, if the time and date is before today, and something else, if it's after.

graph LR
	A([1995-08-15T12:00:00]) --First value--> C(Conditional 'lte')
	B([Today]) --Secound value--> C
	A --First value--> D(Conditional 'gt')
	B --Secound value--> D
	C --True--> E{Before today}
	D --False--> F{After today}

Caveats

  • If you want to make a comparison to a static value, make sure it is set everytime a comparision is being made, since the block will not remeber anything. JSON Decode is very usefull here.
  • With everything other than 'eq' and 'ne', make sure to read it out like this: First value is greater than or equal to second value.
