All the GIFs you'll ever need are at Gifs-R-Us

Gifs-R-Us 🎉

A GIF browser built on giphy.com's API.

Running locally

The app is built using create-react-app and can be run according to CRA's setup:

1. yarn install
2. yarn start

The grid

The grid uses a CSS Grid layout with columns 200px wide and an automatic number of rows 10px tall. Trending and Search pages use fixed-height GIFs so the GIFs are assigned a fix number of rows, rounded up to the nearest 10px, so that the browser can handle the columns as the window is resized.

Data loading

LOOP ->

1. Trending/Search pages check if scrollY+clientHeight is within offset of bottom of scrollable height
   • Not within offset of bottom? END
2. Request next block of GIFs starting at offset
3. Update of offset when fetch returns, triggers start of LOOP

<- END

• Scroll listener on window starts at top of LOOP
• Unmounting the page removes scroll listener and cancels any inflight requests

Notes

• Search and Trending pages ended up being quite similar in their data loading, and ideally could be factored into a common hook and potentially a common reducer and set of actions.
