YAML Unist Parser

yaml-unist-parser is a JavaScript library designed to parse YAML strings and produce an Abstract Syntax Tree (AST) that is compatible with the unist specification. This makes it a suitable tool for applications that process YAML content using a unified syntax tree, such as linters, formatters, and compilers within the unist ecosystem. The current stable version is 3.1.0, with a recent major release (v3.0.0) indicating active development, though a precise release cadence isn't published. Key differentiators include its focus on generating a unist-compatible AST, enhanced node positioning within the AST, and improved comment attaching, which are crucial for tools like Prettier that rely on precise AST details for formatting.
