Blocks that carry values#

Data blocks carry values along the edges of a flow. They produce constants, build structures, pull fields out of a response, or hold a value under a name for later. None of them has a side effect. The category has thirteen blocks, grouped below by what they do.

Constants#

Seven blocks each emit a single fixed value on their Value output when the flow reaches them. Set the value in the inspector, except where noted.

Block	What it emits
String	A fixed piece of text
Number	A fixed number
Boolean	A fixed true or false
Null	The value null, with nothing to configure
Raw	A free-form value, useful for an object or list written by hand
Now	The current time in milliseconds, with nothing to configure
Date	The time in milliseconds for a date you pick

Select#

Select pulls a value out of an object. It has a Data input and a Selected output. Set a path in the inspector, for example data.items[0].name, and the block emits the value found at that path.

Builders#

Three blocks assemble larger values from their inputs.

• List: builds an array and emits it on Array.
• Record: builds an object from named key and value pairs and emits it on Object.
• Template: fills placeholders written as {{name}} in a piece of text and emits the result on Text.

Each builder grows extra input ports as you add items, pairs, or variables in the inspector.

Variables#

Two blocks store and recall a value by name. Create Variable takes a Data input and saves it under the name you set, with no output. Get Variable has no input and emits the saved value on its Value output. A variable belongs to the current run. The flow clears it when it runs again.

Note Validate looks like a data block but sits in the Logic category, because it branches on the result. See Logic.
