@neo4j/cypher-builder - npm Package Versions

1.7.3

Patch Changes

• #236 34552dc Thanks @angrykoala! - Support for chained .yield:

  const customProcedure = new Cypher.Procedure("customProcedure", []).yield("result1").yield(["result2", "aliased"]);
  

  is equivalent to:

  const customProcedure = new Cypher.Procedure("customProcedure", []).yield("result1", ["result2", "aliased"]);
  

  and results in the Cypher:

  CALL customProcedure() YIELD result1, result2 AS aliased
  

1.7.2

Patch Changes

• #230 f37cc99 Thanks @angrykoala! - Support for passing undefined to .where:

  const n = new Cypher.Node();
  new Cypher.Match(n).where(undefined).return(n);
  

  This will generate the following Cypher:

  MATCH(n)
  RETURN n
  

  Note that the WHERE clause is omitted if the predicate is undefined

1.5.2

Patch Changes

• #194 0c40f04 Thanks @angrykoala! - Refactors mixins. Due to this, multiple top-level clauses nested in the same clause will explicitly fail, instead of silent failing:

  The following is not supported;

  const match = new Cypher.Match();
  
  match.with();
  match.return();
  

  In favor of the following:

  const match = new Cypher.Match();
  
  match.with().return();
  

• #195 6b24fdd Thanks @angrykoala! - Support for expressions on Pattern properties:

  const pattern = new Cypher.Pattern(node).withProperties({
      name: Cypher.plus(new Cypher.Literal("The "), new Cypher.Literal("Matrix")),
  });
  

  Results in:

  (this0: {name: "The " + "Matrix"})
  

• #199 58dfee6 Thanks @angrykoala! - Fix RawCypher types

• #198 bfb1c97 Thanks @angrykoala! - Deprecates using With.with when nested with already exists in favour of addColumn:

  const withQuery = new Cypher.With(node);
  
  withQuery.with(node2);
  withQuery.with("*");
  

  Instead, it should be:

  const withQuery = new Cypher.With(node);
  
  const nestedWith = withQuery.with(node2);
  nestedWith.addColumn("*");

  new Cypher.RawCypher((env) => {
      const myVar = new Cypher.Variable();
      return Cypher.utils.compileCypher(myVar, env);
  });
