felid-helmet

Using Helmet middlewares in your Felid app to help improving security.

npm install felid-helmet

yarn add felid-helmet

const Felid = require('felid')
const helmet = require('felid-helmet')

const app = new Felid()
app.plugin(helmet, options)

The following table displays all middlewares in Helmet, and the default ones. (Data comes from Helmet's doc)

Module	Default?
contentSecurityPolicy for setting Content Security Policy
crossdomain for handling Adobe products' crossdomain requests
dnsPrefetchControl controls browser DNS prefetching	✓
expectCt for handling Certificate Transparency
featurePolicy to limit your site's features
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	✓

Pass an option to the middleware:

app.use(helmet, {
  xssFilter: { mode: null }
})

Disable a default middleware:

app.use(helmet, { xssFilter: false })

To enable a middleware, you can set the property to true (and use the default option), or just pass the option to it.

app.use(helmet, {
  expectCt: { maxAge: 123 },
  hpkp: true
})
