graph
node.get
Read one graph node.
strata graph get-nodedb.graphs.get_node(graph: 'str', node_id: 'str', *, as_of: 'Optional[int]' = None, as_of_time: 'Optional[TimeLike]' = None) -> 'Any'wire graph_get_node
Reads one node by id, returning its properties, declared object type, entity binding, and last-write commit coordinates. A removed or never-written node reads back as no data. Accepts `as_of` for time travel.
Optional reads distinguish present data from missing data. When version or timestamp facts exist on the executor output, SDK mappings should preserve them.

Example
Read a node's properties, or nothing if absent.
strata graph create socialstrata graph add-node social alice --type person --properties {"age":30}strata graph get-node social alicestrata graph get-node social absent
_ = db.graphs.create("social")_ = db.graphs.add_node("social", "alice", properties={"age": 30}, object_type="person")db.graphs.get_node("social", "alice").propertiesdb.graphs.get_node("social", "absent") is None
Parameters
| Name | Type | Required | Description |
|---|---|---|---|
| graph | string | yes | Graph name. |
| node_id | string | yes | Node id. |
| as_of | integer or null | no | Read as of a position on the logical commit timeline - the `timestamp` from `history` output, not the `version`, and never a calendar date. Reads the graph state visible at that timeline position. To read as of a real time, use `as_of_time` instead. |
| as_of_time | integer or null | no | Read as of a real time: a wall-clock instant in microseconds since the Unix epoch (UTC), as reported by `committed_at` on a write ack or on any `history` row. Resolves to the commit at or before that instant, and fails rather than guessing if the instant falls outside the branch's recorded history. Mutually exclusive with `as_of`. |
| branch | string or null | no | Target branch. Defaults to the executor handle branch. |
| space | string or null | no | Target product space. Defaults to `"default"`. |
