Is `push-manifest.json` not generated automatically in Polymer 3.0?

[kimamula]

Is it possible to generate push-manifest.json automatically in Polymer 3.0? If not, is there a plan to support it?

FYI, preact-cli supports automatic push-manifest.json generation by implementing PushManifestPlugin webpack plugin.

I followed the "Build for production" guide. But my push-manifest.json is almost empty:

{
  "src/my-app.js": {}
}

If a add some fragments in polymer.json, these files are listed in push-manifest.json:

{
  "src/myview-1.js": {},
  "src/myview-2.js": {},
  "src/listview.js": {}
}

But that's not what I expected...

The last paragraph in the section about the dynamic imports says:

You don't need to list dynamic imports as fragments. The latest Polymer build tools analyze your code and find your dynamic imports, provided they are expressed with static strings. There's no need to list them as separate fragments.

What am I doing wrong?

This is my polymer.json:

{
  "npm": true,
  "moduleResolution": "node",
  "lint": {
    "rules": [
      "polymer-3"
    ]
  },
  "entrypoint": "index.html",
  "shell": "src/my-app.js",
  "sources": [
    "src/my-app.js",
    "images/**/*"
  ],
  "fragments": [
    "src/myview-1.js"
    "src/myview-2.js"
    "src/listview.js"
  ],
  "extraDependencies": [
    "manifest.json",
    "browserconfig.xml",
    "node_modules/@webcomponents/webcomponentsjs/*.js",
    "!node_modules/@webcomponents/webcomponentsjs/gulpfile.js",
    "node_modules/@webcomponents/webcomponentsjs/bundles/*.js"
  ],
  "builds": [
    {
      "preset": "es6-unbundled",
      "basePath": true,
      "addServiceWorker": false
    }
  ]
}

It works if you disable transformModulesToAmd:

{
  ...
  "builds": [
    {
      "preset": "es6-unbundled",
      "js": {
        "transformModulesToAmd": false
      }
    }
  ]
}
