How to export constants defined using object destructuring

Question

Guided by eslint's prefer-destructuring rule, I defined some constants like this:

const {
    NODE_ENV,
    API_URL,
} = process.env;

Is it possible to export these constants by prefixing the statement by export?

export const {
    NODE_ENV,
    API_URL,
} = process.env;

This would seem natural, but eslint-plugin-import complains about a violation of the import/named rule: API_URL not found in '../constants'. In fact, this usage of export is also not described on the relevant MDN page.

Do we then have to repeat all constants in a separate export statement?

const {
    NODE_ENV,
    API_URL,
} = process.env;

export {
    NODE_ENV,
    API_URL,
};

Yes, this is totally valid according to the spec. You can use destructuring patterns in the declarations of exported consts.

Sounds like that plugin is broken. In fact, your exact use case was reported as working before.
