Application config holds information about the current release of the web project.

Simplest example is:

{
  "content_url": "https://5027caf9.ngrok.com",
  "release": "2015.09.01-13.30.35"
}

It should be placed in your www folder as chcp.json file. It is packed with the application and describes the version of the project that is installed on the device from the store.

You can either create it manually, or let cordova-hcp utility to do it for you. Just run cordova-hcp init in your project's root folder, and then on every new build execute cordova-hcp build. For more details read the documentation for the CLI client.

URL on the server, where all your project files are located. Plugin will use it as a base url to download content manifest and all updated files. This is a required option.

Any string that describes your web project version. Should be unique for each release. Based on it plugin will detect if new content is available for download. This is a required option.

Important: plugin will compare release values as strings for equality, and if they are not equal - it will decide that new release is available.

Minimum version of the native side that is required to run this web content. For example, if you add new plugin to the project - most likely it will require native version to update. In order to prevent user from downloading web content that he can't use right now - you increase the min_native_interface value.

In the application you define current native version like so:

<chcp>
    <native-interface version="some_number" />
</chcp>

Lets say, that in config.xml we set native interface version to 5:

<chcp>
    <native-interface version="5" />
</chcp>

And current application config on the server is:

{
  "content_url": "https://5027caf9.ngrok.com",
  "release": "2015.09.01-13.30.35",
  "min_native_interface": 5
}

In that case plugin will load and install update without any problem, since native side can handle new web content.

At some point we release a new version and publish it on the server with the config:

{
  "content_url": "https://5027caf9.ngrok.com",
  "release": "2015.09.05-12.20.15",
  "min_native_interface": 10
}

When plugin loads that new config from the server and sees, that it's min_native_interface is higher then the <native-interface /> in config.xml - it's not gonna load new release. Instead, it will send chcp_updateLoadFailed notification with error, stating that application update is required. In details this is described in Request application update through the store section below.

Note: right now you can't specify different values for min_native_interface for different platforms. But this can be added later, if needed.

Defines when to perform the update. Supported values are:

• start - install update when application is launched. Used by default.
• resume - install the update when application is resumed from background state.
• now - install update as soon as it has been downloaded.

{
  "content_url": "https://5027caf9.ngrok.com",
  "release": "2015.09.05-12.20.15",
  "update": "resume"
}

You can disable automatic installation through the JavaScript. How to do that - read in JavaScript module section.

Package name of the Android version of the application. If defined - used to redirect user to the applications page on the Google Play Store.

Identification number of the application, for example: id345038631. If defined - used to redirect user to the applications page on the App Store.
