When using babel-plugin-transform-decorators-legacy, decorators work just fine in src/main.js. Dependencies imported from there, though, throw an error during parsing if they contain decorators (unexpected token on the '@'). The syntax of both decorators is the same. The external dependency decorator is this one.
Expected is that the decorator plugin would work for files imported from a dependency as well as from files in the project's source directory.
- npm i && jspm i
- jspm build src/main.js
If you remove the import from src/main.js and rebuild, the error is gone.
