Build presets provide an easy way to define common build configurations in your polymer.json file. There are 3 build presets we put in polymer.json file in Shop:

es5-bundled

• js: {minify: true, compile: true}
• css: {minify: true}
• html: {minify: true}
• bundle: true
• addServiceWorker: true
• addPushManifest: true
• insertPrefetchLinks: true

es6-unbundled

• js: {minify: true, compile: false}
• css: {minify: true}
• html: {minify: true}
• bundle: false
• addServiceWorker: true
• addPushManifest: true
• insertPrefetchLinks: true

es6-bundled

• js: {minify: true, compile: false}
• css: {minify: true}
• html: {minify: true}
• bundle: true
• addServiceWorker: true
• addPushManifest: true
• insertPrefetchLinks: true

Run the command to build the presets:

polymer build

Use polymer serve to serve a specific build preset of the app. For example:

polymer serve build/es5-bundled

Our production deployment of SHOP is hosted on App Engine with Node.js. You can examine its configuration on the app-engine-node branch of this repository and compare it with the master branch.
