Typescript compiler fails when using react css themr with error Default export of the module has or is using private name 'TReactCSSThemrTheme'

[sahilgupta202]

Typescript Version : 2.4.2 React CSS Themr: 2.1.2

Replication Steps

1. Create a component that uses themr. themr('Identifier')(ComponentName);
2. Run the Typescript compiler

It will throw the following error error TS4082: Default export of the module has or is using private name 'TReactCSSThemrTheme'. error TS4082: Default export of the module has or is using private name 'ThemedComponentClass'.

Quick fix: just import it ;)

[sahilgupta202]

Yes @belohlavek we used that, but that is not a good solution because TS Lint will fail as we are not using them and those will be unsed imports. Also, importing is private member of a library is never good as it may change in future updates.

I've opened a request to fix issues like these in TypeScript by bringing declaration files to parity with language features. https://github.com/microsoft/TypeScript/issues/35822
