Typify Type Parser

typify-parser is a JavaScript library designed to parse declarative type signature strings, primarily intended for use within the broader `typify` ecosystem for runtime type-checking. It takes human-readable type declarations, such as `(foo, bar 42) -> quux`, and transforms them into a structured JSON Abstract Syntax Tree (AST) representation. This AST details the type components, including function types, product types, identifiers, and literal values like numbers. Additionally, it provides utility methods like `freeVars` to extract unbound type variables from the parsed structure. The package is currently at version `1.1.0`, but it was last published in July 2015, indicating it is no longer actively maintained. Its parent project, `typify`, also appears to be dormant. Developers considering this package should be aware of its abandoned status and the potential compatibility issues with modern JavaScript environments and module systems. Its core differentiation was its ability to convert custom type signature strings into a machine-readable format for subsequent type validation by `typify`.
