# --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 repl.it starter project](https://repl.it/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/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}`
|
||||
|
||||
# --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
|
||||
|
||||
```
|
||||
|
||||
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.
|

Develop a 2D real time multiplayer game using the HTML Canvas API and [Socket.io](https://socket.io/) that is functionally similar to this: <https://secure-real-time-multiplayer-game.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-secure-real-time-multiplayer-game/) and complete your project locally.
|

|
||||
|

```js
|
||||
(getUserInput) => {
|
||||
assert(
|
||||
!/.*\/secure-real-time-multiplayer-game\.freecodecamp\.rocks/.test(
|
||||
getUserInput('url')
|
||||
)
|
||||
);
|
||||
};
|
||||
```
|
||||
|
||||
Multiple players can connect to a server and play.
|
||||
|
||||
```js
|
||||
|
||||
```
|
||||
|
||||
Each player has an avatar.
|
||||
|
||||
```js
|
||||
|
||||
```
|
||||
|
||||
Each player is represented by an object created by the `Player` class in `Player.mjs`.
|
||||
|
||||
```js
|
||||
|
||||
```
|
||||
|
||||
At a minimum, each player object should contain a unique `id`, a `score`, and `x` and `y` coordinates representing the player's current position.
|
||||
|
||||
```js
|
||||
|
||||
```
|
||||
|
||||
The game has at least one type of collectible item. Complete the `Collectible` class in `Collectible.mjs` to implement this.
|
||||
|
||||
```js
|
||||
|
||||
```
|
||||
|
||||
At a minimum, each collectible item object created by the `Collectible` class should contain a unique `id`, a `value`, and `x` and `y` coordinates representing the item's current position.
|
||||
|
||||
```js
|
||||
|
||||
```
|
||||
|
||||
Players can use the WASD and/or arrow keys to move their avatar. Complete the `movePlayer` method in `Player.mjs` to implement this.
|
||||
|
||||
```js
|
||||
|
||||
```
|
||||
|
||||
The `movePlayer` method should accept two arguments: a string of "up", "down", "left", or "right", and a number for the amount of pixels the player's position should change. `movePlayer` should adjust the `x` and `y` coordinates of the player object it's called from.
|
||||
|
||||
```js
|
||||
|
||||
```
|
||||
|
||||
The player's score should be used to calculate their rank among the other players. Complete the `calculateRank` method in the `Player` class to implement this.
|
||||
|
||||
```js
|
||||
|
||||
```
|
||||
|
||||
The `calculateRank` method should accept an array of objects representing all connected players and return the string `Rank: currentRanking/totalPlayers`. For example, in a game with two players, if Player A has a score of 3 and Player B has a score of 5, `calculateRank` for Player A should return `Rank: 2/2`.
|
||||
|
||||
```js
|
||||
|
||||
```
|
||||
|
||||
Players can collide with a collectible item. Complete the `collision` method in `Player.mjs` to implement this.
|
||||
|
||||
```js
|
||||
|
||||
```
|
||||
|
||||
The `collision` method should accept a collectible item's object as an argument. If the player's avatar intersects with the item, the `collision` method should return `true`.
|
||||
|
||||
```js
|
||||
|
||||
```
|
||||
|
||||
All players are kept in sync.
|
||||
|
||||
```js
|
||||
|
||||
```
|
||||
|
||||
Players can disconnect from the game at any time.
|
||||
|
||||
```js
|
||||
|
||||
```
|
||||
|
||||
Prevent the client from trying to guess / sniff the MIME type.
|
||||
|
||||
```js
|
||||
|
||||
```
|
||||
|
||||
Prevent cross-site scripting (XSS) attacks.
|
||||
|
||||
```js
|
||||
|
||||
```
|
||||
|
||||
Nothing from the website is cached in the client.
|
||||
|
||||
```js
|
||||
|
||||
```
|
||||
|
||||
The headers say that the site is powered by "PHP 7.4.3" even though it isn't (as a security measure).
|
||||
|
||||
```js
|
||||
|
||||
```

Build a full stack JavaScript app that is functionally similar to this: <https://stock-price-checker.freecodecamp.rocks/>.
|
||||
|
||||
Since all reliable stock price APIs require an API key, we've built a workaround. Use <https://stock-price-checker-proxy.freecodecamp.rocks/> to get up-to-date stock price information without needing to sign up for your own key.
|
||||
|
||||
Working on this project will involve you writing your code using one of the following methods:
|
||||
|

# --instructions--
|
||||
|
||||
1. SET `NODE_ENV` to `test` without quotes and set `DB` to your MongoDB connection string
|
||||
2. Complete the project in `routes/api.js` or by creating a handler/controller
|
||||
3. You will add any security features to `server.js`
|
||||
4. You will create all of the functional tests in `tests/2_functional-tests.js`
|
||||
|
||||
Write the following tests in `tests/2_functional-tests.js`:
|
||||
|
||||
- Viewing one stock: GET request to `/api/stock-prices/`
|
||||
- Viewing one stock and liking it: GET request to `/api/stock-prices/`
|
||||
- Viewing the same stock and liking it again: GET request to `/api/stock-prices/`
|
||||
- Viewing two stocks: GET request to `/api/stock-prices/`
|
||||
- Viewing two stocks and liking them: GET request to `/api/stock-prices/`
|
||||
|
||||
# --hints--
|
||||
|
||||
You can provide your own project, not the example URL.
|
||||
|
||||
```js
|
||||
(getUserInput) => {
|
||||
assert(
|
||||
!/.*\/stock-price-checker\.freecodecamp\.rocks/.test(getUserInput('url'))
|
||||
);
|
||||
};
|
||||
```
|
||||
|
||||
You should set the content security policies to only allow loading of scripts and CSS from your server.
|
||||
|
||||
```js
|
||||
async (getUserInput) => {
|
||||
const data = await fetch(getUserInput('url') + '/_api/app-info');
|
||||
const parsed = await data.json();
|
||||
assert.isTrue(
|
||||
parsed.headers['content-security-policy'].includes("script-src 'self'")
|
||||
);
|
||||
assert.isTrue(
|
||||
parsed.headers['content-security-policy'].includes("style-src 'self'")
|
||||
);
|
||||
};
|
||||
```
|
||||
|
||||
You can send a `GET` request to `/api/stock-prices` with form data containing a NASDAQ stock ticker. Returned will be an object with the property `stockData`.
|
||||
|
||||
```js
|
||||
async (getUserInput) => {
|
||||
const data = await fetch(
|
||||
getUserInput('url') + '/api/stock-prices?stock=GOOG'
|
||||
);
|
||||
const parsed = await data.json();
|
||||
assert.property(parsed, 'stockData');
|
||||
};
|
||||
```
|
||||
|
||||
The `stockData` property includes the `stock` ticker as a string, the `price` as a number, and `likes` as a number.
|
||||
|
||||
```js
|
||||
async (getUserInput) => {
|
||||
const data = await fetch(
|
||||
getUserInput('url') + '/api/stock-prices?stock=GOOG'
|
||||
);
|
||||
const parsed = await data.json();
|
||||
const ticker = parsed.stockData;
|
||||
assert.typeOf(ticker.price, 'number');
|
||||
assert.typeOf(ticker.likes, 'number');
|
||||
assert.typeOf(ticker.stock, 'string');
|
||||
};
|
||||
```
|
||||
|
||||
You can also pass along a `like` field as `true` (boolean) to have your like added to the stock(s). Only 1 like per IP should be accepted.
|
||||
|
||||
```js
|
||||
|
||||
```
|
||||
|
||||
If you pass along 2 stocks, the returned value will be an array with information about both stocks. Instead of `likes`, it will display `rel_likes` (the difference between the likes on both stocks) for both `stockData` objects.
|
||||
|
||||
```js
|
||||
async (getUserInput) => {
|
||||
const data = await fetch(
