[dependabot-preview]

Bumps helmet from 3.23.3 to 4.0.0.

Changelog

Sourced from helmet's changelog.

4.0.0 - 2020-08-02

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 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
• 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.
• helmet.hsts:
  • Dropped support for includeSubdomains with a lowercase D. See #231
  • Dropped support for setIf. Read this if you need help.. See #232
• helmet.xssFilter no longer accepts options. Read "How to disable blocking with X–XSS–Protection" and "How to enable the report directive with X–XSS–Protection" if you need the legacy behavior.
