Bump helmet from 3.23.3 to 4.1.0

[dependabot-preview]

Bumps helmet from 3.23.3 to 4.1.0.

Changelog

Sourced from helmet's changelog.

4.1.0 - 2020-08-15

Added

• helmet.contentSecurityPolicy:
  • Directive values can now include functions, as they could in Helmet 3. See #243

Changed

• Helmet should now play more nicely with TypeScript

Removed

• The HelmetOptions interface is no longer exported. This only affects TypeScript users. If you need the functionality back, see this comment

4.0.0 - 2020-08-02

See the Helmet 4 upgrade guide for help upgrading from Helmet 3.

Added

• helmet.contentSecurityPolicy:
  • If no default-src directive is supplied, an error is thrown
  • Directive lists can be any iterable, not just arrays

Changed

• This package no longer has dependencies. This should have no effect on end users, other than speeding up installation time.
• helmet.contentSecurityPolicy:
  • There is now a default set of directives if none are supplied
  • Duplicate keys now throw an error. See helmetjs/csp#73
  • This middleware is more lenient, allowing more directive names or values
• helmet.xssFilter now disables the buggy XSS filter by default. See #230

Removed

• Dropped support for old Node versions. Node 10+ is now required
• helmet.featurePolicy. If you still need it, use the feature-policy package on npm.
• helmet.hpkp. If you still need it, use the hpkp package on npm.
• helmet.noCache. If you still need it, use the nocache package on npm.
• helmet.contentSecurityPolicy:
  • Removed browser sniffing (including the browserSniff and disableAndroid parameters). See helmetjs/csp#97
  • Removed conditional support. This includes directive functions and support for a function as the reportOnly. Read this if you need help.
  • Removed a lot of checks—you should be checking your CSP with a different tool
  • Removed support for legacy headers (and therefore the setAllHeaders parameter). Read this if you need help.
  • Removed the loose option
  • Removed support for functions as directive values. You must supply an iterable of strings
• helmet.frameguard:
  • Dropped support for the ALLOW-FROM action. Read more here.
• helmet.hidePoweredBy no longer accepts arguments. See this article to see how to replicate the removed behavior. See #224.
