ゴール: Manipulate YAML Document AST paths, preserve comments, control scalar styles, and transform nodes with visit in yaml HOW
パッケージ: yaml 2.9.0
環境: node
作成日: 2026-08-17T14:47:12Z

yaml.parseDocument returns a Document AST whose scalar values can be read and mutated via path arrays while preserving existing comments upon serialization
doc.getIn with keepScalar flag returns the AST Scalar node to allow inspecting and updating scalar formatting styles
doc.addIn, doc.deleteIn, and doc.hasIn manipulate sequence and mapping AST nodes at nested paths
yaml.visit traverses document AST nodes and removes targeted nodes when returning visit.REMOVE
doc.toJS with mapAsMap: true converts YAML mapping structures to native JavaScript Map instances
