Feature Highlight

Potions

Each potion has a dedicated details page showing an image with distinct coloring based on potion type, a name, potion, type, and description. Potions can be viewed by all site visitors, but can only be interacted with by authenticated users.

Comments

Each potion page has a comments section related to that specific potion. Logged in users can add, edit, or delete their comments from the page. Comments can be viewed by all visitors regardless of authentication.

Search

From the home screen or all pages, can search by potion name. Searching an empty field returns all potions. Potion type filtering can be performed from the search results page. The search feature can be accessed by all visitors.

Demo

Visitors wishing to access all site features granted to logged in users can use the 'Demo' button to bypass the signup/login process.

Challenges

AJAX requests

Using AJAX in a real world application proved more difficult than implementing in a controlled educational environment.
- All persons worked together to find the solution breaking down the problems and resolving one section at a time.

AJAX resolution

Frontend

async function postNewComment(url = '', data) {
    const response = await fetch(url, {
        method: 'POST',
        headers: {
            'Content-Type': 'application/json'
        },
        body: JSON.stringify({ "comm": data })
    });
    return response.json(); // returns a promise
};

window.addEventListener('DOMContentLoaded', event => {
    const addCom = document.querySelector('.commentSubmit');

    addCom.addEventListener('click', postComment);

    async function postComment(e) {
        const potionId = e.target.id;
        const newComment = document.getElementById('commentInput');
        const response = await postNewComment(`/potions/${potionId}`, newComment.value);

Backend

router.post('/:id(\\d+)', asyncHandler(async (req, res, next) => {
  const { userId } = req.session.auth;
  const users = await db.User.findByPk(userId);
  const comment = await db.Comment.create({
    comment: req.body.comm,
    user_id: userId,
    potion_id: req.params.id
  });
  res.json({ "comm": comment, "users": users });
}));
