How do I define schemas in HelixDB?

Define the structure of your graph using HelixQL schema definitions. Every node, edge, and vector automatically includes an implicit ID field.

Define node types and their properties:

N::NodeType {
  field1: String,
  field2: U32
}

Define relationships between nodes with properties:

E::EdgeType {
  From: NodeType,
  To: NodeType,
  Properties: {
    field1: String,
    field2: U32
  }
}

Define vector types with metadata properties:

V::VectorType {
  field1: String
}
