babel-plugin-tcomb

Babel plugin that adds runtime type checking from Flow annotations using tcomb. Version 0.4.0, released 2020-09-05. This is the latest stable release; prior versions support Babel 6, latest supports Babel 7. Transforms Flow type annotations into runtime assertions via tcomb. Different from flow-remove-types or babel-plugin-transform-flow-strip-types because it keeps the type information for runtime validation. Works alongside Flow for hybrid static + dynamic checking. Supports refinement types, immutability enforcement, and IO boundary validation. Abandoned as of November 2021; no commits or releases since 0.4.0.
