A working draft of the Concept Curation prototype.
This template is a starting point for building apps using a drawer-based
layout. The layout is provided by app-layout
elements.
This template, along with the polymer-cli
toolchain, also demonstrates use
of the "PRPL pattern" This pattern allows fast first delivery and interaction with
the content at the initial route requested by the user, along with fast subsequent
navigation by pre-caching the remaining components required by the app and
progressively loading them on-demand as the user navigates through the app.
The PRPL pattern, in a nutshell:
- Push components required for the initial route
- Render initial route ASAP
- Pre-cache components for remaining routes
- Lazy-load and progressively upgrade next routes on-demand
First, install Polymer CLI using npm (we assume you have pre-installed node.js).
npm install -g polymer-cli
And install the dependencies:
npm install && bower install
This command serves the app at http://localhost:8080
and provides basic URL
routing for the app:
polymer serve --open
The included gulpfile.js
relies on the polymer-build
library,
the same library that powers Polymer CLI. Out of the box it will clean the
build
directory, and provide image minification. Follow the comments in the
gulpfile.js
to add additional steps like JS transpilers or CSS preprocessors.
gulpfile.js
also generates a service-worker.js
file with code to pre-cache
the dependencies based on the entrypoint and fragments specified in
polymer.json
.
npm run build
This command serves the minified version of the app at http://localhost:8080
:
polymer serve build/
This command will run Web Component Tester against the browsers currently installed on your machine:
polymer test
The gulpfile.js
already contains an example build step that demonstrates how
to run image minification across your source files. For more examples, refer to
the section in the polymer-build README on extracting inline sources.
