Logic & Transform

Conditions, loops, switches, filters, aggregation, and a JavaScript sandbox for custom logic.

Overview

The Logic & Transform group is the workhorse of a pipeline — it holds nodes for branching, looping, reshaping, and scripting data as it flows from a source toward an output. This group spans four underlying node categories: Logic, Transformer, Transform, and Script.

Nodes in This Group

Logic

Node	Description
Condition	Branches the pipeline based on a true/false expression evaluated against the upstream value.
Transform	Applies a simple field-level transformation to the upstream value.
Loop / Iterator	Repeats a downstream branch once per item in an upstream array.
Switch / Match	Routes the pipeline down one of several branches based on matching a value against a set of cases.
Math / Calculation	Evaluates a numeric expression using upstream values as variables.
State / Cache	Stores or retrieves a value across workflow runs.
Manual Approval	Pauses the workflow until a user approves or rejects continuation.

Transformer

Node	Description
GitIngest	Converts a Git repository's contents into a single text blob for downstream AI processing.
Summarizer	Produces a shorter summary of the upstream text.
Translator	Translates the upstream text into a target language.

Transform

Node	Description
Filter	Keeps only the items in an upstream array that match a condition.
Transform	Reshapes upstream data into a different structure.
Aggregate	Reduces an upstream array into a single summary value (sum, count, average, etc.).
Sort	Reorders an upstream array by a chosen field.
Dedup	Removes duplicate items from an upstream array.
Template Renderer	Fills a text template with upstream values.
Data Anonymizer	Masks or removes sensitive fields from upstream data.
Compression	Compresses or decompresses upstream data.

Script

Node	Description
Script Engine	Runs custom JavaScript against the upstream value, available as the `input` variable.
JSON Editor	Edits upstream data as JSON directly in the node's panel.
Plain Text	Passes through or edits upstream data as plain text.

Usage Tips

Reach for Script Engine last

Try Filter, Transform, Aggregate, and Sort first — they cover most reshaping needs without code. Drop into Script Engine only when the logic can't be expressed with the built-in nodes.

Manual Approval pauses execution

A workflow with a Manual Approval node will sit paused, waiting for a user to approve or reject it, before continuing to downstream nodes. Use this for workflows that touch production data or send external communications.

Frequently Asked Questions

What variable holds the upstream value inside Script Engine?

The input variable holds whatever value the connected upstream node produced — a string, number, array, or JSON object depending on that node's output.

Does Loop / Iterator run its branch in parallel or one at a time?

Items are processed sequentially, one at a time, in the order they appear in the upstream array.
