## Description
<section id='description'>
Build a full stack JavaScript app that is functionally similar to this: <a href="https://anonymous-message-board.freecodecamp.rocks/" target="_blank">https://anonymous-message-board.freecodecamp.rocks/</a>.
Working on this project will involve you writing your code using one of the following methods:

- Clone <a href='https://github.com/freeCodeCamp/boilerplate-project-messageboard/' target='_blank'>this GitHub repo</a> and complete your project locally.
- Use <a href='https://repl.it/github/freeCodeCamp/boilerplate-project-messageboard' target='_blank'>our repl.it starter project</a> 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
<section id='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/threads/{board}` with an invalid `delete_password`
- Deleting a reply with the correct password: DELETE request to `/api/threads/{board}` with a valid `delete_password`
- Reporting a reply: PUT request to `/api/replies/{board}`

## Tests
<section id='tests'>

```yml
tests:
  - text: You can provide your own project, not the example URL.
    testString: |
      getUserInput => {
        assert(!/.*\/anonymous-message-board\.freecodecamp\.rocks/.test(getUserInput('url')));
      }
  - text: Only allow your site to be loaded in an iFrame on your own pages.
    testString: "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'));
      }"
  - text: Do not allow DNS prefetching.
    testString: "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'));
      }"
  - text: Only allow your site to send the referrer for your own pages.
    testString: "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'));
      }"
  - text: 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).
    testString: ''
  - text: 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`.
    testString: ''
  - text: 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.
    testString: ''
  - text: 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.
    testString: ''
  - text: 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`. 
    testString: ''
  - text: 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]`.
    testString: ''
  - text: 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`.
    testString: ''
  - text: 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`.
    testString: ''
  - text: All 10 functional tests are complete and passing.
    testString: ''
