#310 13fd317
Thanks @angrykoala! - Add support for arbitrary variables in Patterns instead of only Node and Relationship:
#310 13fd317
Thanks @angrykoala! - The following methods in Pattern
class and chains are deprecated:
withoutLabels
withoutVariable
withProperties
getVariables
withoutType
withDirection
withLength
Instead, these properties should be passed as an object, for example:
const a = new Cypher.Variable();
const rel = new Cypher.Variable();
const b = new Cypher.Variable();
const pattern = new Cypher.Pattern(a, { labels: ["Movie"] }).related(rel, { type: "ACTED_IN" }).to(b);
#310 98a8b2f
Thanks @angrykoala! - Deprecate using Node directly on Match, Create and Merge clauses. Use a Pattern instead
#310 7574aee
Thanks @angrykoala! - Deprecate setting up labels and types in Node and Relationship. The following examples are now deprecated:
new Cypher.Node({ labels: ["Movie"] });
new Cypher.Relationship({ type: "ACTED_IN" });
Instead, Nodes and Relationships should be created without parameters. Labels and types should be set in a Pattern:
const n = new Cypher.Node();
const r = new Cypher.Relationship();
const pattern = new Cypher.Pattern(n, { labels: ["Movie"] }).related(r, { type: "ACTED_IN" }).to();

const { cypher } = query.build();
RETURN "the \u212B char" IS NFC NORMALIZED AS normalized
