Catalog of Open Source Software from NASA. Built using Polymer.
Install bower and polymer-cli:
npm install -g bower polymer-cli
bower i
This command serves the app at http://localhost:8080
and provides basic URL
routing for the app:
polymer serve --open
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 minified files are output to the build/unbundled
folder, and are suitable
for serving from a HTTP/2+Push compatible server.
In addition the command also creates a fallback build/bundled
folder,
generated using fragment bundling, suitable for serving from non
H2/push-compatible servers or to clients that do not support H2/Push.
polymer build
This command serves the minified version of the app at http://localhost:8080
in an unbundled state, as it would be served by a push-compatible server:
polymer serve build/unbundled
This command serves the minified version of the app at http://localhost:8080
generated using fragment bundling:
polymer serve build/bundled
When deploying to a static web server (with no HTTP/2+Push), be sure to copy
the files from build/bundled
(NOT the project directory) which
contains a functional service worker and minified files.
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).
