Exercise 4: NG2 APP in logged in bundle¶

Bootstrap¶

Install npm dependencies:

cd exercise4/static
npm install

Add your angular 2 component¶

In your exercise4/static/app directory, add a file named app.component.ts. Use this file to do anything you would like to the page. This example will stick with the angular 2 quickstart code. We hope you like typescript:

import { Component } from '@angular/core';
@Component({
  selector: '.my-app',
  template: '<h1>NG2 from Exercise 4</h1>'
})
export class AppComponent { }

You can do whatever in this module however, please notice how we changed the selector to .my-app. In Angular 2, the selector can be anything. By changing it to a class name, it’ll be easier for us to choose where we want to bootstrap our angular 2 component.

Register static resource directory¶

Next, let’s register the static directory we just placed our script into. To register, you need to add ZCML registration for the static directory your script is in. Add this to the exercise4/configure.zcml file:

<plone:static
     directory="static"
     type="plone"
     name="exercise4"
     />

Build the file with webpack¶

Our deployment is built using webpack:

cd exercise4/static
webpack

Whenever you make a change to your component files, webpack will auto re-build the distribution

Register JavaScript resource¶

Let’s register our script as a JavaScript resource with Plone. In the exercise4/profiles/default/registry.xml file, add configuration to register your script:

<records prefix="plone.bundles/exercise4"
          interface='Products.CMFPlone.interfaces.IBundleRegistry'>
  <value key="merge_with">logged-in</value>
  <value key="enabled">True</value>
  <value key="compile">False</value>
  <value key="expression">python: member is not None</value>
  <value key="jscompilation">++plone++exercise4/exercise4-compiled.min.js</value>
  <value key="csscompilation">++plone++exercise4/exercise4-compiled.css</value>
  <value key="last_compilation">2016-10-04 00:00:00</value>
</records>

Pay attention to this part of the exercise. Here we merge the bundle with logged-in instead of default. We also added an expression configuration option to specify that we only want this bundle to load for logged in users.

Installation¶

1. Start up your Plone instance
2. Install the Exercise 4 add-on

Running¶

It’s up to you how to apply the component class name to an element of your choice. A couple options available to you are:

1. use TinyMCE source view and add class="my-app" onto any tag
2. customize the theme on your site and add it to an element in your theme file or use a diazo rule diazo rule to dynamically add the class to an element

Development¶

To make sure your changes are loaded after every build with webpack, make sure to go into Site setup -> Resource registries and enabled development mode.

Production¶

Production for this is simple when you’re no longer in development mode on your Plone site. Webpack rebuilds the JavaScript distribution on every change.
