artHouse is a full-stack web application modeled after Instagram. This app is designed for artists to post their work with the social media aspect of users being able to follow artists they find, and like posts they favor. I am planning on adding a bid or buy feature so followers can buy pieces from artists directly. artHouse uses Ruby on Rails for the backend, a PostgreSQL database, and React/Redux architectural framework on the frontend.
The artHouse feed only displays the current users posts and posts of artists the current user follows. On the backend I leverage associations between the users, follows, posts, comments and likes tables. After log in, an API call is made to join the users table with follows table on follower_id using .includes() to avoid N + 1 queueing when iterating through followed_artists to grab all posts, map over post_id's, like_id's and comment_id's. Each post in the post slice of state holds arrays of their like_id's and comment_id's to keep a normalized state. These id's are references when rendering each posts comment index and to persist likes. On the front end a selector puts these post objects into an array and sorts they by the create_at to keep the feed in order.
When a new user signs up and is not following any artists yet, they are redirected to a welcome/Discover page instead of going to the feed so they have a chance to check out some of the top artists artHouse has to offer.
componentDidMount() {
if (this.props.currentUser.followeeIds.length === 0) {
this.props.history.push('/welcome');
} else {
this.props.importFeedPosts();
}
}
Image uploads are managed using Paperclip, Amazon Web Services and react-dropzone. Users can click or drag and drop their image to upload and add a caption. When a user chooses an image, a preview of that image is displayed before they share which removes the dropzone.
updateDraggedFile (e) {
let file = e[0];
let fileReader = new FileReader();
fileReader.onloadend = function() {
this.setState({imageFile: file, imageURL: fileReader.result });
}.bind(this);
if (file) {
fileReader.readAsDataURL(file);
$('.drag-zone').remove();
}
}
The Follow/Edit button is it's own component holding logic to determine if the current user is on their own page an edit button is rendered and on a followed artist's page a follow button is rendered. onCLick an API call is made to create a new Follow to be saved on the backend. On the frontend, each artist has an array of follower_ids. When the user visits an artist page, if current_user.id is included in the artist's follower_ids array, the follow persists and the button renders as Following which makes an API call to destroy that Follow.
let followState = user.followerIds.includes(currentUser.id) ? "Following" : "Follow";
switch(followState) {
case "Following":
return (
<button className="editFollowing" onClick={this.handleUnfollow} >{followState}</button>
);
case "Follow":
return (
<button className="editFollow" onClick={this.handleFollow} >{followState}</button>
);
}
Add a Bid/Buy button on each post which will also display the current bid of the piece. An artist can place a minimum bid, set price, or open the piece up for all bids. User can place a bids and 'win' the piece.
Create a stat page for each artist with graph or chart of how the artist has been selling. If the prices of their pieces have gone up or down so users know if it's a good investment if they are looking for more then just buying a piece they like for aesthetic purposes.
Implement search for users to search by artist or hashtag.
