I used following specifications.
1) rails 5.1.3
2) ruby 2.4.1
3) rail with webpacker
4) Angular 4.3.4 with webpacker (Typescript)
I create new rail app using command rails new my-rails-app --webpack-angular.
Folder structure
After that, as per instruction under app/javascript/packs/application.js and app/javascript/packs/hello_angular.js, I added <%= javascript_pack_tag 'application' %> in application.html.erb to head tag next after javascript_include_tag.
Also add below markup to body tag in layout application.html.erb
// <hello-angular>Loading...</hello-angular>
//
// <%= javascript_pack_tag 'hello_angular' %>
application.html.erb
<!DOCTYPE html>
<html>
<head>
<title>AngularOnRailsWithWebpack</title>
<%= csrf_meta_tags %>
<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track': 'reload' %>
<%= javascript_include_tag 'application', 'data-turbolinks-track': 'reload' %>
<%= javascript_pack_tag 'application' %>
</head>
<body>
<hello-angular>Loading...</hello-angular>
<%= javascript_pack_tag 'hello_angular' %>
<%= yield %>
</body>
</html>
Now create new scaffolding by running rails g scafolld post title:string desc:text and set post index page as root path
Now run rails server by running rails s and webpack server by running ./bin/webpack-dev-server
Works fine.
But When I navigate routes by click on new post or edit post it fire errors in web console like below.
Solution I tried
1) Remove javascript_include_tag from application.html.erb. But it will remove turbolink. I don't want to remove that.
2) Restore javascript_include_tag and update index.ts under app/javascript/hello-angular/index.ts. Add turbolink load event as per this video instruction https://www.youtube.com/watch?v=lGToT9RyDxc
Index.ts
import './polyfills.ts';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppModule } from './app/app.module';
document.addEventListener('turbolinks:load', () => {
platformBrowserDynamic().bootstrapModule(AppModule);
})
Work fine. It will render code fine but still same zone error in web console.
May be this is rails issue. If so then I hope it will resolve in next patch release.
Can any one help that how to resolve this issue ? What I am doing wrong.
