@travellocal/babel-plugin-declare-const-enum

A plugin for Babel to replace uses of declare const enum types from ambient typing files (i.e. .d.ts).

During the Babel run, this plugin

• finds the relevant tsconfig.json file for each /.ts(x)?/ file encountered
• uses the TypeScript compiler to find ambient const enums
• replaces any usages of the const enum with the value defined (e.g. if MyEnum.Foo == 1, this plugin will replace MyEnum.Foo with 1).

Usage

First yarn add -D or npm install --save-dev @travellocal/babel-plugin-declare-const-enum.

    return options;
  },
  // ...
};
