This article covers app settings in Microsoft Dynamics 365 Commerce.

The \src\settings\app.settings.json file holds app settings for global configurations, routes, and themes. The following example shows a JavaScript Object Notation (JSON) file that includes a section for each type of setting.

{
    "config":{
        "logoUrl":{
            "type": "image",
            "friendlyName": "Logo Image",
            "description": "Logo Image"
        }
    },
    "routes": {
        "cart": {
            "friendlyName": "Cart Page Route",
            "description": "Cart Page Route",
            "default": "/cart2"
        },
        "checkout": {
            "friendlyName": "Checkout Page Route",
            "description": "Checkout Page Route",
            "default": "/checkout"
        }
    },
    "themes": {
       "default":{
            "friendlyName": "Default Theme"
        }
        "spring":{
            "friendlyName": "Spring Theme"
        }
    }
}

Config section

The config section of the app.settings.json file supports global configuration fields. These fields can be set at the site level in the authoring tools, and they are shared across all modules by using the this.props.context.app.config.* application programming interface (API).

The global configuration fields are helpful when you have data that should be set only one time across the whole online site, but the data is required by multiple modules. For example, an API key for ratings and reviews has the same value across the online site, and that value is required by multiple modules. Modules themselves also support site-scoped configuration settings, but those settings can't be shared across different modules.

The schemas for these configurations follow the same schemas that are used for module configurations.

Routes section

The routes section in the app.settings.json file is used to add URL routes in a module. For example, if a module must create a link to the cart page, a "cart" route is added to the JSON file. The route can then be retrieved from the module code by using the authoring tools.

Routes can be accessed in the module view file by using the this.props.context.app.routes.* API.

Themes section

The themes section in the app.settings.json file is used to expose themes to the authoring tools. The themes in this section should match the theme names in the \src\themes\ directory. They should provide localizable friendly names that the authoring tools can show when they are used to set a theme at the site level, or in the template, layout, or page editor.

Localized app settings

Both the friendlyName property and the description property of each app setting should be localized for the site locale in the Dynamics 365 Commerce authoring tools. The src/resources/authoring/global.json file should be updated so that it includes a settings property, and all the settings that are related to resource strings should be listed under that property.

Resource schema

{
    "settings": {
        "<setting_property>": {
            "friendlyName": {
                "value": "",
                "_value.comment": ""
            },
            "description": {
                "value": "",
                "_value.comment": ""
            },
        }
    },
}

Here is an example of a resource file.

{
    "settings": {
         "logoUrl": {
            "friendlyName": {
                "value": "Logo Image",
                "_value.comment": ""
            },
            "description": {
                "value": "Logo Image",
                "_value.comment": ""
            }
        },
         "cart": {
            "friendlyName": {
                "value": "Cart URL",
                "_value.comment": ""
            },
            "description": {
                "value": "Cart page route",
                "_value.comment": ""
            }
        }
    }
}
