Allow package.json to define what "ionic build" and "ionic serve" do in custom projects

Looking at CLI 4.8.0, custom projects are hard-coded to always throw an error upon build/serve, without a way to define a custom build/serve process.

I would expect ionic build by default to run tasks that are not specific to Angular, such as auto-generating the app icon and splash screen assets, and allow a hook in the package.json of the project to run other custom build tasks if needed.

This is a small roadblock for Vue adoption.

Just pushed a commit that makes this work with projects generated by the Vue CLI.

Choose custom during ionic init:

$ ionic init

ionic.config.json is generated.

{
  "name": "test",
  "integrations": {},
  "type": "custom"
}

Make the following modifications to package.json:

   "scripts": {
+    "ionic:build": "vue-cli-service build",
+    "ionic:serve": "vue-cli-service serve",
     "serve": "vue-cli-service serve",
     "build": "vue-cli-service build",
     "lint": "vue-cli-service lint"
   },

ionic build & ionic serve (and build/serve during Cordova/Capacitor commands) will now work using the vue-cli-service!

This will be in Ionic CLI 4.9.0. Thanks!

The main AppFlow Vue example project is missing these two lines 😦
