First, install Polymer CLI using npm (we assume you have pre-installed node.js).
npm install -g polymer-cli
Second, install Bower using npm
npm install -g bower
Install the node_modules:
npm install
Install the bower_components:
bower install
This command serves the app at http://127.0.0.1:8081
and provides basic URL
routing for the app:
npm run serve
The npm run build
command builds your Polymer application for production, using build configuration options provided by the command line or in your project's polymer.json
file.
You can configure your polymer.json
file to create multiple builds. This is necessary if you will be serving different builds optimized for different browsers. You can define your own named builds, or use presets. See the documentation on building your project for production for more information.
The Polymer Starter Kit is configured to create three builds using the three supported presets:
"builds": [
{
"preset": "es5-bundled"
},
{
"preset": "es6-bundled"
},
{
"preset": "es6-unbundled"
}
]
Builds will be output to a subdirectory under the build/
directory as follows:
build/
es5-bundled/
es6-bundled/
es6-unbundled/
es5-bundled
is a bundled, minified build with a service worker. ES6 code is compiled to ES5 for compatibility with older browsers.es6-bundled
is a bundled, minified build with a service worker. ES6 code is served as-is. This build is for browsers that can handle ES6 code - see building your project for production for a list.es6-unbundled
is an unbundled, minified build with a service worker. ES6 code is served as-is. This build is for browsers that support HTTP/2 push.
Run polymer help build
for the full list of available options and optimizations. Also, see the documentation on the polymer.json specification and building your Polymer application for production.
This command serves your app. Replace build-folder-name
with the folder name of the build you want to serve.
polymer serve build/build-folder-name/
