Important security headers for Fastify. It is a tiny wrapper around helmet.


npm i fastify-helmet


Simply require this plugin, and the basic security headers will be set.

const fastify = require('fastify')()
const helmet = require('fastify-helmet')

fastify.register( helmet, // Example disables the contentSecurityPolicy middleware but keeps the rest. { contentSecurityPolicy: false } )

fastify.listen(3000, err => { if (err) throw err })

How it works

is just a tiny wrapper around helmet that adds an
hook. It accepts the same options of Helmet, and you can see more in the helmet documentation.
