interface HelmetOptions - no longer public

[ctomczyk]

Seems interface HelmetOptions is no longer public in helmet version 4.1.0.

Is that change intentional?

interface HelmetOptions {
    contentSecurityPolicy?: MiddlewareOption<ContentSecurityPolicyOptions>;
    dnsPrefetchControl?: MiddlewareOption<XDnsPrefetchControlOptions>;
    expectCt?: MiddlewareOption<ExpectCtOptions>;
    frameguard?: MiddlewareOption<XFrameOptionsOptions>;
    hidePoweredBy?: MiddlewareOption<never>;
    hsts?: MiddlewareOption<StrictTransportSecurityOptions>;
    ieNoOpen?: MiddlewareOption<never>;
    noSniff?: MiddlewareOption<never>;
    permittedCrossDomainPolicies?: MiddlewareOption<XPermittedCrossDomainPoliciesOptions>;
    referrerPolicy?: MiddlewareOption<ReferrerPolicyOptions>;
    xssFilter?: MiddlewareOption<never>;
}

I hope that change will be reverted

Unfortunately, reverting this is not possible, and its exposure was a bug in v4.0.0.

However, you can emulate it yourself (lifted from this comment):

import helmet = require('helmet');
const opts: Parameters<typeof helmet>[0] = {
  // strongly typed helmet options go here...
};
helmet(opts);

Hope this helps.
