Overview

The Boolean Expression Evaluator worker functions as a simple conditional processor, similar to an if statement in most programming languages. It receives a textual boolean expression, evaluates it, and returns the resulting true/false value. This makes it useful for dynamic decision‑making within workflows where the condition is supplied at runtime.

Inputs

• expression (string) – A valid boolean expression written in standard logical syntax.
  • Supported operators: && (AND), || (OR), ! (NOT)
  • Parentheses can be used to control precedence, e.g., (a && b) || !c
  • Operands may be literals (true, false) or variables that are resolved from the worker’s execution context.

Minimal Example Usage

Assume the worker is invoked with the following input payload:

{
  "expression": "(true && false) || !false"
}

When executed, worker evaluates the expression step‑by‑step:

1. true && false → false
2. !false → true
3. false || true → true

The final output returned by the worker is:

{
  "result": true
}

This concise example demonstrates how the worker can be embedded in a larger workflow to perform conditional logic without writing explicit if statements.
