Hi all 
Thanks for following along. I’m here to let y’all know that we’ve updated the preview site with the first batch of front-end updates to WaniKani. You can use your regular WaniKani credentials here: http://preview.wanikani.com/.
Remember: The preview site is not a test site! The data is from your regular account, so all lessons and reviews are the real deal.
We’d love it for you to try some lessons and quizzes out on the preview site. Try your add-ons and user scripts, especially if they are used on parts of the page that have been converted.
For more nitty gritty details on this update:
- What changed? The top half of the components on the Lessons page and Quiz page have been converted to React, specifically: the Home button, the Skip button, the Stats bar on the top right (with the number of Radicals, Kanji, Vocabulary and total completed), the main character display and the bar that displays what kind of question you’re answering. If you want to follow along with the React changes, I recommend using a React browser extension.
-
What hasn’t changed? None of the features, user interfaces or design have changed. For the most part, CSS class names, DOM element structures and hierarchies have not changed. The data for these components, for example, the number of Kanji left, still come from
$.jStorage.
If you notice any bugs, please @wanikanijavi and I (@gomakuma) know in this thread.
Update, 2/12: Thanks to @sornvru for pointing out the whitelist. All scripts you’re testing should have preview.wanikani.com on their whitelist at the top of the script code as well. For example, the Wanikani Ultimate Timeline script’s whitelist includes both sites with this line: // @include /^https://(www|preview).wanikani.com/(dashboard)?$/. The script won’t work the @include line only has wanikani.com and not preview.wanikani.com
Thank you and happy reviewing!
