ngXosLib

This is a collection of helpers to develop views as Angular SPA.

Tools

These tools are designed to help develop a graphical view. They assume XOS is running on your system and responding at: localhost:9999. The xos/configurations/frontend is normally sufficient for GUI development.

Vendors

XOS comes with a set of common libraries, as listed in bower.json:

  • angular
  • angular-route
  • angular-resource
  • angular-cookie
  • ng-lodash

These libraries are served through Django, so they are not included in your minified vendor file. To add a library and generate a new file (that will override the old one):

  • enter ngXosLib folder
  • run bower install [myPackage] --save
  • rebuild the file with gulp vendor

NOTE before adding libraries please discuss it on the devel list to avoid this file becoming too big

Helpers

XOS comes with a helper library that is automatically loaded in the Django template.

To use it, add xos.helpers to your required modules:

angular.module('xos.myView', [
  'xos.helpers'
])

It will automatically add a token to all your requests. Eventually you can take advantage of some other services:

  • NoHyperlinks Interceptor: will add a ?no_hyperlinks=1 to your request, to tell Django to return ids instead of links.
  • XosApi wrapper for /xos endpoints.
  • XoslibApi wrapper for /xoslib endpoints.
  • HpcApi wrapper for /hpcapi endpoints.

NOTE: for the API related service, check the documentation in Section Apigen.

ngXosViews

In addition to auto-generated Django Admin Views and developer-defined Service Views, a set of custom views can be generate in XOS.

These views are based on AngularJs and they communicate with XOS through the REST APIs, providing a powerful and flexible way to present and manage data.

How to Create a View

Environment setup

Before getting started with new views you should create a configuration file to define the backend environment to be used. This file have to be in views/env/default.js and it content have to be:

module.exports = {
  host: 'XOS Url',
  xoscsrftoken: 'CSRF Token',
  xossessionid: 'Sessio ID'
};

You can define multiple environment creating other configurations (eg: views/env/production.js) with the same structure.

Getting Started

We have created a yeoman generator to help scaffold views.

As it is in an early stage of development, you should manually link it to your system. To do this enter /views/ngXosLib/generator-xos and run npm link.

To Generate a New View

From /views run yo xos. This command will create a new folder with the provided name in /views/ngXosViews that contains your application.

If you left View name empty it should be /views/ngXosViews/sampleView

Run a Development Server

In your view folder run npm start.

This will install the required dependencies and start a local server with BrowserSync.

If you want to use a different backend environment you can call the command with an environment variable: NODE_ENV=production.js npm start

Publish Your View

Once your view is done, from your view root folder, run: npm run build.

This will build your application and copy files in the appropriate directories for use by Django.

At this point you can enter: http://localhost:9999/admin/core/dashboardview/add/ and add your custom view.

NOTE: url field should be template:xosSampleView

Add This View to a Configuration Setup

You can easily set this as a default view in a configuration by editing the {config}.yml file for that configuration. Add these lines:

{TabName}:                                    
  type: tosca.nodes.DashboardView              
  properties:                                  
      url: template:{viewName}     

Then edit the User section (normally it starts with padmin@vicci.org) as follows:

padmin@vicci.org:                                          
  type: tosca.nodes.User                                   
  properties:                                              
      firstname: XOS                                       
      lastname: admin                                      
      is_admin: true                                       
  requirements:                                            
      - tenant_dashboard:                                  
          node: Tenant                                     
          relationship: tosca.relationships.UsesDashboard  
      - {custom_dashboard}:                              
          node: {TabName}                                 
          relationship: tosca.relationships.UsesDashboard  

Install Dependencies in Your App

To install a local dependency use bower with --save. Common modules are saved in devDependencies as they already loaded in the Django template.

The npm start command watches your dependencies and will automatically inject it in your index.html.

Linting

A styleguide is enforced through EsLint and is checked during the build process. We highly recommend installing the linter in your editor to have realtime hints.

Test

The generator sets up a test environment with a default test. To run it, execute: npm test
