Smart Manufacturing Execution System for Small-Midsize industry. Using polymer, firebase, WebUSB (In developing). THIS PROJECT IS STILL IN DEVELOPMENT PLEASE CONSIDER CAREFULLY.

Polymer App Starter Kit

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

Migrating from Polymer Starter Kit v1?

Setup Project

Prerequisites

NodeJS version >= 6.x

https://nodejs.org/en/

Install polymer-cli:

npm install -g polymer-cli

Install bower:

npm install -g bower

Start the development server

This command serves the app at http://localhost:8080 and provides basic URL routing for the app:

polymer serve --open

Build

This command performs HTML, CSS, and JS minification on the application dependencies, and generates a service-worker.js file with code to pre-cache the dependencies based on the entrypoint and fragments specified in polymer.json. The output files are in build/default which suitable for serving from a HTTP/2+Push compatible server.

Build the project:

polymer build

Preview the build

This command serves the minified version of the app at http://127.0.0.1:8081 in an unbundled state, as it would be served by a push-compatible server:

polymer serve --open

This command serves the production version of the app at http://localhost:8080 generated using fragment bundling:

polymer serve build/defaukt

Run tests

This command will run Web Component Tester against the browsers currently installed on your machine.

polymer test

Adding a new view

You can extend the app by adding more views that will be demand-loaded e.g. based on the route, or to progressively render non-critical sections of the application. Each new demand-loaded fragment should be added to the list of fragments in the included polymer.json file. This will ensure those components and their dependencies are added to the list of pre-cached components (and will have bundles created in the fallback bundled build).
