Utility

app_info

Outputs the application version and data directory.

Outputs:

• version (Text) — application version
• data_dir (Text) — application data directory path

See also: platform, io/env_var

args

Provides a named input argument. In compiled graphs, this becomes a CLI argument; in the editor, it outputs the default value.

Inputs:

• name (Text) — argument name (used as the CLI flag)
• default (Any) — default value when the argument is not provided

Output: value (Any) — the resolved argument value

batch_collect

Accumulates one value per batch iteration into an output array.

Inputs:

• value (Any) — value to collect from this iteration

Output: results (Json) — accumulated array of collected values

See also: batch_input

batch_input

Provides items to a batch execution loop.

Inputs:

• items (Json) — JSON array of items to iterate over

Outputs:

• value (Any) — current item from the batch
• index (Number) — zero-based iteration index
• total (Number) — total number of items

Example: items = [1,2,3] → 1

See also: batch_collect

boolean

Outputs a constant boolean value.

Inputs:

• value (Boolean) — constant to output

Output: value (Boolean) — the boolean value

date_add

Adds a duration to a timestamp.

Inputs:

• timestamp (Number) — base Unix timestamp in milliseconds
• amount (Number) — number of units to add (negative to subtract)
• unit (Text) — seconds, minutes, hours, or days

Output: result (Number) — adjusted timestamp in milliseconds

Example: amount = 1, timestamp = 0, unit = days → 86400000

date_diff

Calculates the difference between two timestamps.

Inputs:

• a (Number) — first timestamp in milliseconds
• b (Number) — second timestamp in milliseconds
• unit (Text) — seconds, minutes, hours, or days

Output: result (Number) — difference in specified units (a - b)

Example: a = 86400000, b = 0, unit = days → 1

expression

Evaluates a JavaScript expression with up to four variable inputs.

Inputs:

• expression (Text) — JavaScript expression to evaluate
• a (Any) — first variable
• b (Any) — second variable
• c (Any) — third variable
• d (Any) — fourth variable

Output: result (Any) — expression result

Example: a = 10, b = 5, expression = a + b * 2 → 20 Example: a = hello, b = world, expression = a.toUpperCase() + ' ' + b → HELLO world

format_date

Formats a Unix timestamp into a date string.

Inputs:

• timestamp (Number) — Unix timestamp in milliseconds
• format (Text) — format pattern (YYYY, MM, DD, HH, mm, ss)

Output: result (Text) — formatted date string

Example: format = YYYY-MM-DD, timestamp = 0 → 1970-01-01

image_constant

Outputs a constant image from embedded base64 data.

Output: image (Image) — the image

json

Outputs a constant JSON value from a text editor.

Inputs:

• value (Text) — JSON text to parse

Output: result (Json) — parsed JSON value

now

Outputs the current Unix timestamp in milliseconds.

Output: timestamp (Number) — current time in Unix milliseconds

See also: format_date, date_add

number

Outputs a constant number.

Inputs:

• value (Number) — constant to output

Output: value (Number) — the number value

parse_date

Parses a date string into a Unix timestamp.

Inputs:

• text (Text) — date string to parse

Output: timestamp (Number) — Unix timestamp in milliseconds

Example: text = 1970-01-01T00:00:00.000Z → 0
