This repo is a rebuild of https://github.com/bpswim90/sift, with some changes to play around with performance optimization and to make it a PWA (Progressive Web App).

The major difference is this version is bundled with Webpack (via the Vue-cli), rather than Browserify. This allowed me to implement lazy-loading of routes in the app, and take advantage of some of the magical optimizing that webpack does.

One other really cool thing is that this version can be run as a PWA! This is again thanks to the magic of Vue-cli and webpack.

Performance improvements so far have been negligible; the app's loading clocks slightly faster, though not noticeably so. On an emulated 3G phone speed, both versions seem to load in around 6s.

One major limitation is the large size of bootstrap and jquery, which are used in the project. I suspect there would be performance gains from only loading the most necessary styles, and deferring the loading of the rest of bootstrap.

Caching may also help, though I haven't gotten into that yet.

The user experience when the app is run as a PWA has some bugs and hiccups; for example, the lack of a back button. Also, sometimes a page will take a long time to load for reasons I don't yet understand.

iOS:

• Navigate to https://bpswim90.github.io/sift-2.0/ in your iPhone
• In Safari, click the share button and scroll over to "Add to Home Screen"
• Give the app a name if needed and click Add.
• You're done! You should now have an icon on your homescreen that you can use to launch Sift.
