Hello all,
I have an large legacy Meteor application I am trying to refactor and update to the latest version of Meteor and I’m running in to an issue with the .babelrc file and my local packages (everything in the ./packages/*). As of version 1.3.4 it is possible to use the .babelrc file to add additional transforms like ```transform-class-properties``. But if I add a property to one of the classes in one of my packagess the application will not start and throw out an error along lines of:
=> Errors prevented startup:
While processing files with ecmascript (for target web.browser):
packages/andre:package-with-class-properties/package-with-class-properties.js:6:1: /packages/andre:package-with-class-properties/package-with-class-properties.js: Missing class properties transform.
While building for os.osx.x86_64:
imports/import-with-class-properties/index.js:2:1: /imports/import-with-class-properties/index.js: Missing class properties transform.
While processing files with ecmascript (for target os.osx.x86_64):
packages/andre:package-with-class-properties/package-with-class-properties.js:6:1: /packages/andre:package-with-class-properties/package-with-class-properties.js: Missing class properties transform.
=> Your application has errors. Waiting for file change.
I have created an experimentation project which can be found at: https://github.com/AndreSteenveld/meteor-import-from-packages
So far I’ve found this forum post by @clayne, which does suggest it is possible to use the transforms in packages. Although I think it uses the gadicc:ecmascript-hot package for complication instead of the default ecmascript package, which isn’t an option for me. A few posts later @benjamn suggests that the .babelrc file will work everywhere.
To make sure I have the same .babelrc file in every package I’ve tried symlinking it in to all the package directories (in the example project that would be $ln -s ./.babelrc ./packages/package-with-class-properties/.babelrc). But that causes the application to go in to an infinite loop during the startup:
=> Started MongoDB.

My questions/issues are:
- How do I use the
.babelrcfile in my project and how do I make sure my local packages are converted as well? - If that is not possible is there an work around, that will not prevent me following the Meteor update path?
The application this applies to has roughly 40 packages, and a total line count of ~80k. I have to stress the fact that it is not the best designed application so “just” moving all the packages to the ./imports/ directory is not really an option.
