Summary: A demonstration of how to synchronize a single collection with RHMAP. Community Project : Feed Henry Target Product: RHMAP Product Versions: RHMAP 3.8.0+ Source: https://github.com/feedhenry-templates/sync-cordova-app
Prerequisites: fh-js-sdk : 2.14.+, cordova 5.0+

What is it?

This application manages items in a collection that is synchronized with a remote RHMAP cloud application. The user can create, update, and delete collection items. Refer to www/fhconfig.json and www/js/services.js for the relevant pieces of code and configuraiton.

If you do not have access to a RHMAP instance, you can sign up for a free instance at https://openshift.feedhenry.com/.

How do I run it?

RHMAP Studio

This application and its cloud services are available as a project template in RHMAP as part of the "Sync Framework Project" template.

Local Clone (ideal for Open Source Development)

If you wish to contribute to this template, the following information may be helpful; otherwise, RHMAP and its build facilities are the preferred solution.

Prerequisites

• fh-js-sdk : 2.14.+
• cordova: 5.0+

Build instructions

local dev with cordova serve

• npm install
• Edit www/fhconfig.json to include the relevant information from here.
• Build and run locally

cordova serve  

Go to http://localhost:8000/

npm dependencies

The fh-js-sdk and other development dependencies are defined in package.json and included in a www/js/main.js.

• This generated www/main.js file is checked-in to allow RHMAP studio preview to statically serve dependencies.

• The www/js/app.js file is browserified and acts as a bridge between template script and npm dependencies.

• All the other JavaScript files in the template app will not be browserified, in order for you to be able to experiment live edit in RHMAP Studio preview.

Updating fh-js-sdk version

To update the JS SDK:

• change the version in package.json
• run npm install a grunt task is automatically ran to regenerate main.js
• check-in git repo the new package.json + main.js

Grunt

This template uses Grunt, the Javascript Task Runner. To use Grunt with this Template App, do the following:

• Install grunt: npm install -g grunt-cli
• In your App directory, run: npm install. This installs Grunt plugins, etc for use with this App.
• Run grunt serve to preview this App locally

Local development

You can also use Grunt to point your App at a local developement server. To do this, use the grunt serve:local command. Some notes on using the serve:local task:

• by default, the local server development url is: http://localhost:8001
• you can change this directly in your local Gruntfile.js, in the app config:

  app: {
    // configurable paths
    app: 'www',
    url: '',
    default_local_server_url: 'http://localhost:8001'
  },

• you can also pass a 'url' optional flag to server:local, e.g. grunt serve:local --url=http://localhost:9000

• You can also write your own tasks by extending the Gruntfile.js, e.g. add a 'serve:live' target that hits your server in your FeedHenry live enivronment.

How does it work?

Initialization

init in www/js/services.js is the method which is responsible for configuring and setting up syncronization. Further details are available in our API documentation.

Creating and Editing Items

save(item) in www/js/services.js is called by the UI when the item is created, and update(item) in www/js/services.js is called for updates.

Removing Items

deleteItem(item) in www/js/services.js is called by the UI when a user swipes to remove an item from the list.
