--- id: 587d8249367417b2b2512c40 title: Configure Helmet Using the ‘parent’ helmet() Middleware challengeType: 2 forumTopicId: 301575 dashedName: configure-helmet-using-the-parent-helmet-middleware --- # --description-- As a reminder, this project is being built upon the following starter project on [Repl.it](https://repl.it/github/freeCodeCamp/boilerplate-infosec), or cloned from [GitHub](https://github.com/freeCodeCamp/boilerplate-infosec/). `app.use(helmet())` will automatically include all the middleware introduced above, except `noCache()`, and `contentSecurityPolicy()`, but these can be enabled if necessary. You can also disable or configure any other middleware individually, using a configuration object. **Example:** ```js app.use(helmet({ frameguard: { // configure action: 'deny' }, contentSecurityPolicy: { // enable and configure directives: { defaultSrc: ["self"], styleSrc: ['style.com'], } }, dnsPrefetchControl: false // disable })) ``` We introduced each middleware separately for teaching purposes and for ease of testing. Using the ‘parent’ `helmet()` middleware is easy to implement in a real project. # --hints-- no tests - it's a descriptive challenge ```js assert(true); ``` # --solutions-- ```js /** Backend challenges don't need solutions, because they would need to be tested against a full working project.
