This is my ambitious attempt at the Uber Sudoku coding challenge.
To play online:
- It looks beautiful, I spent quite a lot of time tweaking the CSS. At one point I had a dynamically blurred background but it was too slow on mobile devices, so I had to revert.
- Auto scale to viewport. Renders great on my iphone, ipad and desktop.
- Dynamic grids. With url param, user can play 2x2, 3x3 or 4x4 sudoku. 4x4 with hints is quite fun.
- Beautiful macro-blur background on the background. Leaf is visible on landscape orientation. Thanks to www.desktoplounge.com
- Tiny numbers are shown in the cells when "Show hints" is pressed.
- Input are at the bottom show what values are possible. I wanted to make something that augments the user. No one likes red error boxes.
- When a new grid is generated, we run a little one second animation.
- When the user finishes the sudoku, we spin the blocks and do a happy animation.
- Tested with iphone 5s, ipad 3, Chrome latest, IE11, and Samsung S3.
- My friends think I should actually turn it into an app. They love it.
- I used indentation languages such as jade, stylus and coffeescript for my html, css and javascript. With stylus mixins, I have pre-generated grids for 2x2x2, 3x3x3 and 4x4x4. Coffee is my favourite language to prototype with. Its very expressive.
- Jquery and Underscore. I consider them standard web libs for most of my projects.
- Vuejs. I understand Uber asked me to refrain me from Backbone and similar libs. However I didn't want to write spaghetti view management code. I quite like vuejs for its simplicity and how it handles the view data binding. With coffeescript the code looks very elegant.
- Gulp. The build system is quite magical. Running "gulp" fires up a tiny express server with live-reload. Any time a src file is changed, the files are automatically pre-processed and the browser is hot-loaded with the latest code within milli-seconds. I've used "gulp deploy" automatically update the gh-pages branch to master. The dist folder is setup as an external-repo.
- Tests. I was planning to use jasmine and integrate the tests with watch task, however I didn't get enough time.
Finish game animation.Wifey really insisted that I need to add a happy animation at the end- I could probably improve the initial loading perf and make it offline capable.
- I've been wanting to try sharejs. Multiplayer would make it social.
