Working on these challenges will involve you writing your code using one of the following methods:
|
||
|
|
|
||
|
|
- Clone [this GitHub repo](https://github.com/freeCodeCamp/boilerplate-infosec/) and complete these challenges locally.
|
||
|
|
- Use [our Replit starter project](https://replit.com/github/freeCodeCamp/boilerplate-infosec) to complete these challenges.
|
||
|
|
- Use a site builder of your choice to complete the project. Be sure to incorporate all the files from our GitHub repo.
|
||
|
|
|
||
|
|
When you are done, make sure a working demo of your project is hosted somewhere public. Then submit the URL to it in the `Solution Link` field.
|
||
|
|
|
||
|
|
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`
|
||
|
|
|
||
|
|
```js
|
||
|
|
(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);
|
||
|
|
}
|
||
|
|
);
|
||
|
|
```
|
||
