Bool Block

​

Overview

The Bool Block is used to output a boolean constant or convert an input value into a boolean. It’s particularly useful when you need to create a boolean value for use in other blocks, such as the If Block or If/Else Block.

Conversion Rules

The Bool Block follows JavaScript’s rules for truthy and falsy values when converting input values to booleans. If no input is connected when “Use Value Input” is enabled, it will fall back to using the Value setting.

​

Example: Using a Constant Boolean Value

1. Add a Bool Block to your flow.
2. Set the Value setting to true.
3. Run the flow. The Value output of the Bool Block will be true.

​

Example: Converting an Input to a Boolean

1. Add a Bool Block to your flow.
2. Enable the Use Value Input setting.
3. Add a Text Block to your flow and set the text to "Hello".
4. Connect the output of the Text Block to the Input of the Bool Block.
5. Run the flow. The Value output of the Bool Block will be true, because the string "Hello" is a truthy value in JavaScript.

Error Handling

The Bool Block cannot error under normal circumstances. If “Use Value Input” is enabled and no input is connected, the block will fall back to using the Value setting.
