Description

As a reminder, this project is being built upon the following starter project on Repl.it, or cloned from GitHub. Hackers can exploit known vulnerabilities in Express/Node if they see that your site is powered by Express. X-Powered-By: Express is sent in every request coming from Express by default. The helmet.hidePoweredBy() middleware will remove the X-Powered-By header. You can also explicitly set the header to something else, to throw people off. e.g. app.use(helmet.hidePoweredBy({ setTo: 'PHP 4.2.0' }))

Instructions

Tests

tests:
  - text: helmet.hidePoweredBy() middleware should be mounted correctly
    testString: getUserInput => $.get(getUserInput('url') + '/_api/app-info').then(data => { assert.include(data.appStack, 'hidePoweredBy'); assert.notEqual(data.headers['x-powered-by'], 'Express')}, xhr => { throw new Error(xhr.responseText); })

Solution

/**
  Backend challenges don't need solutions, 
  because they would need to be tested against a full working project.
