PolyMail

PolyMail is an offline, mobile-first, web version of the new Gmail native app UI. It's built using Polymer 1.0 and Service Worker and...is a WIP.

Demo: https://poly-mail.appspot.com/   (mock data: https://poly-mail.appspot.com/?debug)

PolyMail

Note: the app is read only despite what the permissions popup says. Also, most of the buttons don't do anything. There's a lot of missing functionality.

Performance

TLDR: paint is ~393ms and the app loads ~1s on Chrome desktop. Motorola G - Chrome - 3G Fast connection first paint is 1.66s The full performance improvements over the Polymer 0.5 version are documented here.

Setup

In your local checkout, install the deps and Polymer elements

npm install

This will also run bower install for you.

Development & Building

Compile the ES6

While ES6 Classes run natively in Chrome, FF Nightly, Safari 9, and Edge, some of JS in PolyMail still requires compilation using Babel. In particular, scripts/googleapis.js uses ES6 => functions and modules (import statement) in addition to classes.

Compile the JS/CSS:

gulp

This produces a single built and concatenated dist/scripts/bundle.js and compiles the rest of the app into dist/. You're ready to run the app!

Run the app

Use any webserver you'd like. I use npm serve:

serve -p 8080

You must run from /dist

serve -p 8080 serves the root folder, but the app runs the production version from dist/. So be sure to first run gulp, then hit http://localhost:8080/dist/.

Watching files

For easier development, there's a task for rebuilding the vulcanized elements.html bundle and compiling the ES6 as you make changes:

gulp watch

Using test data

Hitting http://localhost:8080?debug will bypass Google Sign-in and use mock data for threads. Under this testing mode, you will no see custom labels in the left nav or user profile images show up on threads.

Deploying

npm run deploy
