--description--

As a reminder, this project is being built upon the following starter project on Repl.it, or cloned from GitHub.

Helmet helps you secure your Express apps by setting various HTTP headers.

--instructions--

All your code for these lessons goes in the myApp.js file between the lines of code we have started you off with. Do not change or delete the code we have added for you.

Install Helmet version 3.21.3, then require it. You can install a specific version of a package with npm install --save-exact package@version, or by adding it to your package.json directly.

--hints--

helmet version 3.21.3 should be in package.json

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/package.json').then(
    (data) => {
      const packJson = JSON.parse(data);
      const helmet = packJson.dependencies.helmet;
      assert(helmet === '3.21.3' || helmet === '^3.21.3');
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
