think-helmet

think-helmet is a wrapper for helmet to work with ThinkJS 3.x. It provides important security headers to make your app more secure by default.

Installation

npm install think-helmet --save

Usage

// src/config/middleware.js
module.exports = [{
  handle: require('think-helmet'),
  options: {

  }
}]

Helmet offers 11 security headers:

| Module | Default? | |---|---| | contentSecurityPolicy for setting Content Security Policy | | | dnsPrefetchControl controls browser DNS prefetching | ✓ | | frameguard to prevent clickjacking | ✓ | | hidePoweredBy to remove the X-Powered-By header | ✓ | | hpkp for HTTP Public Key Pinning | | | hsts for HTTP Strict Transport Security | ✓ | | ieNoOpen sets X-Download-Options for IE8+ | ✓ | | noCache to disable client-side caching | | | noSniff to keep clients from sniffing the MIME type | ✓ | | referrerPolicy to hide the Referer header | | | xssFilter adds some small XSS protections | ✓ |

You can see more in the documentation.

Note:

In order to work well with the helmet HSTS module, think-helmet will augment this.request to include a secure boolean to determine if the request is over HTTPS.

Examples

// src/config/middleware.js
module.exports = [{
  handle: require('think-helmet'),
  options: {
    contentSecurityPolicy: { // set content security policy directives
      directives: {
        defaultSrc: ["'self'"],
        styleSrc: ["'self'", 'maxcdn.bootstrapcdn.com']
      }
    },
    dnsPrefetchControl: false // disable dns prefetch control
  }
}]
