Usage

Run the collector before production builds. Call this after Initialize.

npx @rdlabo/ionic-angular-collect-icons

Put the collector in an npm script so production builds refresh src/use-icons.ts:

  "scripts": {
    "ng": "ng",
    "start": "ng serve",
    "build": "ng build",
+   "prebuild": "npx @rdlabo/ionic-angular-collect-icons",

[!WARNING]
This method cannot be used for production builds without using the npm script.

Add one static icon to a template, for example <ion-icon name="home"></ion-icon>.
Run the collector and confirm the matching export in src/use-icons.ts.
Run npm run build.

Dynamic [name] bindings are not collected. Register those icons manually, or see the binding notes in FAQ.
