decorators (legacy) enforce decorators after export

[jsg2021]

The babel 6 legacy decorators transform allowed decorators on either side of the export... after upgrading to babel 7 using the new decorators transform with legacy: true, code that used decorators before the export are failing with:

error Parsing error: Using the export keyword between a decorator and a class is not allowed. Please use export @dec class instead.

Hey @jsg2021! We really appreciate you taking the time to report an issue. The collaborators
on this project attempt to help as many people as possible, but we're a limited number of volunteers,
so it's possible this won't be addressed swiftly.

If you need any help, or just have general Babel or JavaScript questions, we have a vibrant Slack
community that typically always has someone willing to help. You can sign-up here
for an invite.

Do you have a stack trace or anything? As far as I'm aware, legacy: true should sidestep that error in general. Are you potentially not fully upgraded to the most recent stable version yet?

[jsg2021]

Oh... the error is not from babel cli, its from eslint, & babel-eslint@9.0.0 :/

[loganfsmyth]

Ah, yeah babel-eslint has its own option for that, it's just not documented well yet :( babel/babel-eslint#679

ecmaFeatures: {
  legacyDecorators: true
}

in your ESLint config should resolve it for you.

@jsg2021 I had this exact issue here: #8562 , and that fix worked for me

heads up to anyone copy pasting this.... @loganfsmyth typed 'decotators' (not decorators) which while I'm still laughing about was initially very confused when it seemed to do nothing...
