Issues with TypeScript imports in 4.0.0

Code like below overrides the exported object, which causes default being missing from every module.

module.exports = contentSecurityPolicy;
export default contentSecurityPolicy;

For example, inside index.ts, add console.log("wat", expectCt); under the import, and we’ll see it’s undefined.

+1 for helmet@4.1.0-rc.2. Typing issues are resolved.

For anybody that was previously importing the HelmetOptions interface, e.g. you’re assigning the options to a variable rather than directly invoking the middleware function, you can do it by extracting the type from the middleware arg:

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

This should be fixed in the next version. Please try it out with npm install helmet@4.1.0-rc.2 and let me know what you think. Once I get a few successful reports, I’ll release it.
