Writes a single resolved value into an assign. Think of it as the small cousin of Flow Compose: Compose builds a whole struct; Assign pulls out or computes one value and names it. Good for staging a scalar you want to reuse in several downstream nodes, or for renaming an assign so a step can find it under a different key.

​
Configuration

  • Output assign — the name to write under.
  • Nested path — optional. A dot-separated path inside the target assign (e.g. address.city). When set, the value is written into a nested map, creating intermediate maps if needed. Leave empty for a plain top-level write.
  • Source — where the value comes from. Same vocabulary as Flow Compose:
    • Assign — copy the raw value of another assign.
    • Extract — traverse into a map/struct at a path (get_in-style).
    • Dated property — read a dated property through its canonical facade (supports an optional as-of date).
    • Literal — a fixed JSON-serializable value.

​
Tips

  • The Settings pane lets you control which assigns are snapshotted to the run record — untick short-lived staging assigns to keep the flow_runs table small.
