Build a full-stack JavaScript app that is functionally similar to this: <a href="https://anonymous-message-board.freecodecamp.rocks/" target="_blank" rel="noopener noreferrer nofollow">https://anonymous-message-board.freecodecamp.rocks/</a>.
Working on this project will involve you writing your code using one of the following methods:
NODE_ENV to test without quotes when ready to write tests and DB to your databases connection string (in .env)routes/api.jsserver.jsWrite the following tests in tests/2_functional-tests.js:
/api/threads/{board}/api/threads/{board}/api/threads/{board} with an invalid delete_password/api/threads/{board} with a valid delete_password/api/threads/{board}/api/replies/{board}/api/replies/{board}/api/replies/{board} with an invalid delete_password/api/replies/{board} with a valid delete_password/api/replies/{board}You can provide your own project, not the example URL.
assert(
!/.*\/anonymous-message-board\.freecodecamp\.rocks/.test(
code
)
);
Only allow your site to be loaded in an iFrame on your own pages.
const data = await fetch(code + '/_api/app-info');
const parsed = await data.json();
assert.isTrue(parsed.headers['x-frame-options']?.includes('SAMEORIGIN'));
Do not allow DNS prefetching.
const data = await fetch(code + '/_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.
const data = await fetch(code + '/_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).
const date = new Date();
const text = `fcc_test_${date}`;
const deletePassword = 'delete_me';
const data = { text, delete_password: deletePassword };
const url = code;
const res = await fetch(url + '/api/threads/fcc_test', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify(data)
});
if (res.ok) {
const checkData = await fetch(url + '/api/threads/fcc_test');
const parsed = await checkData.json();
try {
assert.equal(parsed[0].text, text);
assert.isNotNull(parsed[0]._id);
assert.equal(new Date(parsed[0].created_on).toDateString(), date.toDateString());
assert.equal(parsed[0].bumped_on, parsed[0].created_on);
assert.isArray(parsed[0].replies);
} catch (err) {
throw new Error(err.responseText || err.message);
}
} else {
throw new Error(`${res.status} ${res.statusText}`);
}
You can send a POST request to /api/replies/{board} with form data including text, delete_password, & thread_id. This will update the bumped_on date to the comment's date. In the thread's replies array, an object will be saved with at least the properties _id, text, created_on, delete_password, & reported.
const url = code;
const body = await fetch(url + '/api/threads/fcc_test');
const thread = await body.json();
const date = new Date();
const text = `fcc_test_reply_${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} ${res.statusText}`);
}
You can send a GET request to /api/threads/{board}. Returned will be an array of the most recent 10 bumped threads on the board with only the most recent 3 replies for each. The reported and delete_password fields will not be sent to the client.
const url = code;
const res = await fetch(url + '/api/threads/fcc_test');
if (res.ok) {
const threads = await res.json();
try {
assert.equal(res.status, 200);
assert.isAtMost(threads.length, 10);
for (let i = 0; i < threads.length; i++) {
assert.containsAllKeys(threads[i], ["_id", "text", "created_on", "bumped_on", "replies"]);
assert.isAtMost(threads[i].replies.length, 3);
assert.notExists(threads[i].delete_password);
assert.notExists(threads[i].reported);
for (let j = 0; j < threads[i].replies.length; j++) {
assert.notExists(threads[i].replies[j].delete_password);
assert.notExists(threads[i].replies[j].reported);
}
}
} catch (err) {
throw new Error(err.responseText || err.message);
}
} else {
throw new Error(`${res.status} ${res.statusText}`);
}
You can send a GET request to /api/replies/{board}?thread_id={thread_id}. Returned will be the entire thread with all its replies, also excluding the same fields from the client as the previous test.
const url = code;
let res = await fetch(url + '/api/threads/fcc_test');
const threads = await res.json();
const thread_id = threads[0]._id;
res = await fetch(`${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} ${res.statusText}`);
}
You can send a DELETE request to /api/threads/{board} and pass along the thread_id & delete_password to delete the thread. Returned will be the string incorrect password or success.
const url = code;
let res = await fetch(url + '/api/threads/fcc_test');
const threads = await res.json();
const thread_id = threads[0]._id;
let data = { thread_id, delete_password: "wrong_password" };
const res_invalid = await fetch(url + '/api/threads/fcc_test', {
method: 'DELETE',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify(data)
});
data = { thread_id, delete_password: "delete_me" };
res = await fetch(url + '/api/threads/fcc_test', {
method: 'DELETE',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify(data)
});
if (res.ok) {
const deleted = await res.text();
const not_deleted = await res_invalid.text();
try {
assert.equal(res.status, 200);
assert.equal(deleted, "success");
assert.equal(not_deleted, "incorrect password");
} catch (err) {
throw new Error(err.responseText || err.message);
}
} else {
throw new Error(`${res.status} ${res.statusText}`);
}
You can send a DELETE request to /api/replies/{board} and pass along the thread_id, reply_id, & delete_password. Returned will be the string incorrect password or success. On success, the text of the reply_id will be changed to [deleted].
const url = code;
const thread_data = {
text: "fcc_test_thread",
delete_password: "delete_me",
};
await fetch(`${url}/api/threads/fcc_test`, {
method: "POST",

} catch (err) {
throw new Error(err.responseText || err.message);
}
} else {
throw new Error(`${res.status} ${res.statusText}`);
