babel-plugin-redux-saga

Babel plugin (v1.2.0, latest) that enhances redux-saga error messages by adding file location metadata to generator functions and effects. During transpilation, it attaches '@@redux-saga/LOCATION' properties to sagas and call/yield expressions, enabling developer tools to display source file, line number, and code snippet in error traces. Key differentiator: zero runtime overhead since it's a compile-time transform. Still in beta (not recommended for production). Works with Babel 6/7 and redux-saga ^1.0.0-rc.0. Does not support React Native. Inactive development since 2020.
