js-ast-builder

js-ast-builder makes it easy to build Javascript internal DSLs that generate an abstract syntax tree (AST).

Example

Build an arbitrary tree of nodes:

class TreeOfNodes extends AstBuilder {
  constructor() {
    super(["node"])
  }
}

let tree = new TreeOfNodes().build(() =>
  node(1, () => {
    node(2, () =>
      node(3)
    )
    node(4)
  })
)

Output:

└ 1
  ├ 2
  │ └ 3
  └ 4
