As can be watched in the above screen shots, pagination of the card comments was the focus of this iteration.

After the last comment(if the card has no comments the comments section is not displayed), if there are others comments to read, a ‘more’ button is displayed. When the user clicks on this button, it displays an activity indicator and when the next page data is loaded the new comments are appended to the ones already on page.
In the comments bar there are displayed the number of shown comments and the total of them.

Implementation Notes

The first page of comments comes down with the other card data. Successive pages are fetched when the more button is clicked via Trello API calls wrapped in a ‘promisified’ page iteration object(it has a .next() method but it is not an ES6 iterator object) provided by the data module.

This iterator is created in the Comments component getInitialState() method:

this.pageIterator = data.cardCommentPageIterator(this.props.cardId, this.props.pageSize, 2);

and it is then used to fetch successive pages:

this.pageIterator.next()
         .then(
            page => {
               this.setState({
                  items: this.state.items.concat(page),
                  loading: false
               });
            },
            (reason) => {
               console.log('cannot load comment page', reason);
               //throw reason
            }
         )
      ;

v0.4: Card Page

tr-0.4.01

  • Demo (If the app is loading slowly just make a refresh because it could be in the idle state on Openshift)
  • Source code on GitHub

In this iteration it is possible to inspect the details of a card.

Differently from the original Trello design that uses a popup modal to display the card data, I opted for a separate and dedicated fullscreen page, with a design inspired to the Dribbble shot template page.

tr-0.4-00

This is just a first basic version, so some features are missing and the CSS styling is uncomplete.

The layout is organized on two columns, with the main content and the comments on the left and some card auxiliar info and actions in the right column.

I chose to put the card cover image, if any, just under the card title and meta. After this image, it comes the card description and the comments section

In the right column/sidebar there are the number of card votes, the number of attachments and two links to get back to the parent board and to see the original Trello card.

The layout is not responsive yet.

The only card activities retrieved with the Trello API are the comments, and only the first 50 items are showed.
Pagination is coming in 0.4.1.

And other card page upcoming features in 0.4.x will be timeago, attachmnts data, voters, …

Development Notes

At the moment, returning back to the parent board makes the app spawns a new http request to Trello to fetch again the board data. This will be fixed later.

The card description and the comment text can be formatted by the user with Markdown, so the Comment React component, in its .render() method, convert it to a HTML string with Marked and inject it into the DOM with dangerouslySetInnerHTML. Later this could be done with Marked-React.
