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+
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/.
This application and its cloud services are available as a project template in RHMAP as part of the "Sync Framework Project" template.
If you wish to contribute to this template, the following information may be helpful; otherwise, RHMAP and its build facilities are the preferred solution.
- fh-js-sdk : 2.14.+
- cordova: 5.0+
- npm install
- Edit
www/fhconfig.json
to include the relevant information from here. - Build and run locally
cordova serve
Go to http://localhost:8000/
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.
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
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
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.
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.
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.
deleteItem(item)
in www/js/services.js
is called by the UI when a user swipes to remove an item from the list.
