Babel Support

If you use enums inside your models / definitions then those enums are by default inside a namespace with the same name as your model. This is called declaration merging. However, the @babel/plugin-transform-typescript does not support these namespaces, so if you are using babel in your project please use the --useUnionTypes flag to generate union types instead of traditional enums. More info can be found here: Enums vs. Union Types.

Note: If you are using Babel 7 and Typescript 3.8 (or higher) then you should enable the onlyRemoveTypeImports to ignore any 'type only' imports, see https://babeljs.io/docs/en/babel-preset-typescript#onlyremovetypeimports for more info

module.exports = {
    presets: [
        ['@babel/preset-typescript', {
            onlyRemoveTypeImports: true,
        }],
    ],
};
