--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 and complete your project locally.
• Use our Gitpod starter project 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.

--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.

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

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

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.

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.

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).

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.

async (getUserInput) => {
  const url = getUserInput('url');
  const body = await fetch(url + '/api/threads/fcc_test');
  const thread = await body.json();

  const date = new Date();
  const text = `fcc_test_reply_${date}`;
  const delete_password = 'delete_me';
  const thread_id = thread[0]._id;
  const replyCount = thread[0].replies.length;

  const data = { text, delete_password, thread_id };
  const res = await fetch(url + '/api/replies/fcc_test', {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify(data)
  });
  if (res.ok) {
    const checkData = await fetch(`${url}/api/replies/fcc_test?thread_id=${thread_id}`);
    const parsed = await checkData.json();
    try {
      assert.equal(parsed.replies.length, replyCount + 1);
      assert.equal(parsed.replies[0].text, text);
      assert.equal(parsed._id, thread_id);
      assert.equal(parsed.bumped_on, parsed.replies[0].created_on);
    } catch (err) {
      throw new Error(err.responseText || err.message);
    }
  } else {
    throw new Error(`${res.status} ${res.statusText}`);
  }
};

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.

async (getUserInput) => {
  const url = getUserInput('url');
  const res = await fetch(url + '/api/threads/fcc_test');

  if (res.ok) {
    const threads = await res.json();
    try {
      assert.equal(res.status, 200);
      assert.isAtMost(threads.length, 10);
      for (let i = 0; i < threads.length; i++) {
        assert.containsAllKeys(threads[i], ["_id", "text", "created_on", "bumped_on", "replies"]);
        assert.isAtMost(threads[i].replies.length, 3);
        assert.notExists(threads[i].delete_password);
        assert.notExists(threads[i].reported);
        for (let j = 0; j < threads[i].replies.length; j++) {
          assert.notExists(threads[i].replies[j].delete_password);
          assert.notExists(threads[i].replies[j].reported);
        }
      }
    } catch (err) {
      throw new Error(err.responseText || err.message);
    }
  } else {
    throw new Error(`${res.status} ${res.statusText}`);
  }
};

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.

async (getUserInput) => {
  const url = getUserInput('url');
  let res = await fetch(url + '/api/threads/fcc_test');
  const threads = await res.json();
  const thread_id = threads[0]._id;
  res = await fetch(`${url}/api/replies/fcc_test?thread_id=${thread_id}`);

  if (res.ok) {
    const thread = await res.json();
    try {
      assert.equal(res.status, 200);
      assert.isObject(thread);
      assert.containsAllKeys(thread, ["_id", "text", "created_on", "bumped_on", "replies"]);
      assert.isArray(thread.replies);
      assert.notExists(thread.delete_password);
      assert.notExists(thread.reported);
      for (let i = 0; i < thread.replies.length; i++) {
        assert.notExists(thread.replies[i].delete_password);
        assert.notExists(thread.replies[i].reported);
      }
    } catch (err) {
      throw new Error(err.responseText || err.message);
    }
  } else {
    throw new Error(`${res.status} ${res.statusText}`);
  }
};

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.

async (getUserInput) => {
  const url = getUserInput('url');
  let res = await fetch(url + '/api/threads/fcc_test');
  const threads = await res.json();
  const thread_id = threads[0]._id;
  let data = { thread_id, delete_password: "wrong_password" };
  const res_invalid = await fetch(url + '/api/threads/fcc_test', {
    method: 'DELETE',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify(data)
  });
  data = { thread_id, delete_password: "delete_me" };
  res = await fetch(url + '/api/threads/fcc_test', {
    method: 'DELETE',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify(data)
  });

  if (res.ok) {
    const deleted = await res.text();
    const not_deleted = await res_invalid.text();
    try {
      assert.equal(res.status, 200);
      assert.equal(deleted, "success");
      assert.equal(not_deleted, "incorrect password");
    } catch (err) {
      throw new Error(err.responseText || err.message);
    }
  } else {
    throw new Error(`${res.status} ${res.statusText}`);
  }
};

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].

async (getUserInput) => {
  const url = getUserInput('url');

  const thread_data = {
    text: "fcc_test_thread",
    delete_password: "delete_me",
  };
  await fetch(`${url}/api/threads/fcc_test`, {

      const thread = await res.json();
      assert.equal(thread._id, thread_id);
      assert.equal(thread.replies[0]._id, reply_id);
      assert.equal(thread.replies[0].text, "[deleted]");
    } catch (err) {
      throw new Error(err.responseText || err.message);
    }
  } else {
    throw new Error(`${res.status} ${res.statusText}`);
  }
};

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

  }
};

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