syntax-tree

syntax-tree is an organization that contains 100+ projects that deal with syntax trees based on unist. These trees typically deal with content: markdown (mdast), HTML (hast), natural language (nlcst), XML (xast), but also JavaScript (esast).

  • to learn unist, see its readme
  • you can use syntax trees without having to deal with them, by using unified and its plugins

unified

syntax-tree is part of the unified collective, which brings together organisations that work with content as structured data.
