# --description--

Build a full stack JavaScript app that is functionally similar to this: <https://anonymous-message-board.freecodecamp.rocks/>.

Working on this project will involve you writing your code using one of the following methods:

-   Clone [this GitHub repo](https://github.com/freeCodeCamp/boilerplate-project-messageboard/) and complete your project locally.
-   Use [our Replit starter project](https://replit.com/github/freeCodeCamp/boilerplate-project-messageboard) to complete your project.
-   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. Optionally, also submit a link to your projects source code in the `GitHub Link` field.

# --instructions--

1.  Set `NODE_ENV` to test without quotes when ready to write tests and DB to your databases connection string (in `.env`)
2.  Recommended to create controllers/handlers and handle routing in `routes/api.js`
3.  You will add any security features to `server.js`

Write the following tests in `tests/2_functional-tests.js`:

-   Creating a new thread: POST request to `/api/threads/{board}`
-   Viewing the 10 most recent threads with 3 replies each: GET request to `/api/threads/{board}`
-   Deleting a thread with the incorrect password: DELETE request to `/api/threads/{board}` with an invalid `delete_password`
-   Deleting a thread with the correct password: DELETE request to `/api/threads/{board}` with a valid `delete_password`
-   Reporting a thread: PUT request to `/api/threads/{board}`
-   Creating a new reply: POST request to `/api/replies/{board}`
-   Viewing a single thread with all replies: GET request to `/api/replies/{board}`
-   Deleting a reply with the incorrect password: DELETE request to `/api/replies/{board}` with an invalid `delete_password`
-   Deleting a reply with the correct password: DELETE request to `/api/replies/{board}` with a valid `delete_password`
-   Reporting a reply: PUT request to `/api/replies/{board}`

# --hints--

You can provide your own project, not the example URL.

```js
(getUserInput) => {
  assert(
    !/.*\/anonymous-message-board\.freecodecamp\.rocks/.test(
      getUserInput('url')
    )
  );
};
```

Only allow your site to be loaded in an iFrame on your own pages.

```js
async (getUserInput) => {
  const data = await fetch(getUserInput('url') + '/_api/app-info');
  const parsed = await data.json();
  assert.isTrue(parsed.headers['x-frame-options']?.includes('SAMEORIGIN'));
};
```

Do not allow DNS prefetching.

```js
async (getUserInput) => {
  const data = await fetch(getUserInput('url') + '/_api/app-info');
  const parsed = await data.json();
  assert.isTrue(parsed.headers['x-dns-prefetch-control']?.includes('off'));
};
```

Only allow your site to send the referrer for your own pages.

```js
async (getUserInput) => {
  const data = await fetch(getUserInput('url') + '/_api/app-info');
  const parsed = await data.json();
  assert.isTrue(parsed.headers['referrer-policy']?.includes('same-origin'));
};
```

You can send a POST request to `/api/threads/{board}` with form data including `text` and `delete_password`. The saved database record will have at least the fields `_id`, `text`, `created_on`(date & time), `bumped_on`(date & time, starts same as `created_on`), `reported` (boolean), `delete_password`, & `replies` (array).

```js
async (getUserInput) => {
  const date = new Date();
  const text = `fcc_test_${date}`;
  const deletePassword = 'delete_me';
  const data = { text, delete_password: deletePassword };
  const url = getUserInput('url');
  const res = await fetch(url + '/api/threads/fcc_test', {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify(data)
  });
  if (res.ok) {
    const checkData = await fetch(url + '/api/threads/fcc_test');
    const parsed = await checkData.json();
    try {
      assert.equal(parsed[0].text, text);
      assert.isNotNull(parsed[0]._id);
      assert.equal(new Date(parsed[0].created_on).toDateString(), date.toDateString());
      assert.equal(parsed[0].bumped_on, parsed[0].created_on);
      assert.isArray(parsed[0].replies);
    } catch (err) {
      throw new Error(err.responseText || err.message);
    }
  } else {
    throw new Error(`${res.status} ${res.statusText}`);
  }
};
```

You can send a POST request to `/api/replies/{board}` with form data including `text`, `delete_password`, & `thread_id`. This will update the `bumped_on` date to the comment's date. In the thread's `replies` array, an object will be saved with at least the properties `_id`, `text`, `created_on`, `delete_password`, & `reported`.

```js

```

You can send a GET request to `/api/threads/{board}`. Returned will be an array of the most recent 10 bumped threads on the board with only the most recent 3 replies for each. The `reported` and `delete_password` fields will not be sent to the client.

```js

```

You can send a GET request to `/api/replies/{board}?thread_id={thread_id}`. Returned will be the entire thread with all its replies, also excluding the same fields from the client as the previous test.

```js

```

You can send a DELETE request to `/api/threads/{board}` and pass along the `thread_id` & `delete_password` to delete the thread. Returned will be the string `incorrect password` or `success`.

```js

```

You can send a DELETE request to `/api/replies/{board}` and pass along the `thread_id`, `reply_id`, & `delete_password`. Returned will be the string `incorrect password` or `success`. On success, the text of the `reply_id` will be changed to `[deleted]`.

```js

```

You can send a PUT request to `/api/threads/{board}` and pass along the `thread_id`. Returned will be the string `success`. The `reported` value of the `thread_id` will be changed to `true`.

```js

```

You can send a PUT request to `/api/replies/{board}` and pass along the `thread_id` & `reply_id`. Returned will be the string `success`. The `reported` value of the `reply_id` will be changed to `true`.

```js

```

All 10 functional tests are complete and passing.

```js

```
