4. Tutorials

4.1. GR8 CRM Web Site

This guide describes how you can use GR8 CRM Grails plugins to develop a simple web site. The crm-content plugin makes it possible to add HTML pages in a content repository and make the pages publicly accessible.

In this tutorial you will create a Grails application that can serve as a public facing web site. It will have built-in content editing features, including image uploads.

5. Demo applications

This section show demo applications based on GR8 CRM plugins.

5.1. GR8 CRM To-Do

This Grails application uses GR8 CRM plugins to create a simple Contact Management and To-Do application. Clone it and run it, you will have it up and running in a minute or two.

5.2. GR8 Contact

The GR8 Contact application is a simple Contact Management application. It was initially presented at GR8Conf Europe 2014 by Göran Ehrsson (@goeh). The github repository contains 5 branches, each representing a snapshot in time during development.

  • master A plain Grails application, created with grails create-app

  • m1 The plugin crm-contact-ui was installed and contact (company/person) CRUD features are available.

  • m2 The plugin crm-content-ui was installed and documents/files can now be attached to contacts.

  • m3 The plugin crm-task-ui was installed and tasks/appointments with contacts can now be scheduled.

  • m4 The plugin cookie-layout was installed and two themes were created to show that UI can change depending on sub-domain.

Four more branches was added for the Greach 2015 demo.
  • m1-greach: Same as m1 but with Greach theme applied.

  • m2-greach: Same as m2 but with Greach theme applied.

  • m3-greach: Same as m3 but with Greach theme applied and option to import Greach 2015 speakers as contacts.

  • m4-greach: Same as m4 but with Greach theme available. Three themes (Greach, Gr8ConfEU and Gr8ConfUS) available at run-time.

5.3. GR8 CRM Web Site

A sample application that was created by following the GR8 CRM Web Site tutorial (see above) can be found at https://github.com/gr8crm/gr8crm-web

6. Application Events

Most GR8 CRM plugins use application events (synchronous and asynchronous) to communicate with the host application and other GR8 CRM plugins. In this document you can read about some examples where application events are used in GR8 CRM applications. Looking at all these examples you get an understanding of how to think when designing "modular monoliths" with GR8 CRM.
