js setting files

[putan]

I want to be able to use the setting file written in javascript

e.g.

const message = 'hoge';

export default {
    '/hoge' : [
        request: {
            method: 'GET',
        },
        response: {
            status: 200,
            body: {
                result: [
                    { id: 1, msg: message }, // can use variables.
                    { id: 2, msg: message },
                ],
            },
        },
    ],
};
