Configuration Settings

In addition to host level settings that are configurable via host.json, there are also various things that you can configure via App Settings, which you can find on the Configure page in the Azure portal. When running locally, these same settings can be configured via environment variables.

Name	Default value	Description
AzureWebJobsDisableHomepage	false	Set to "true" to disable the default landing page shown for the root of the Azure Functions site
FUNCTIONS_EXTENSION_VERSION	~1	The version specifier governing the version of the Azure Functions runtime will be used. The default is ~1 which means always run with the latest version of the specified major version (in this case 1). This can also be set to a version string to pin the app to specific version (e.g. 1.0.12345).
AzureWebJobs_TypeScriptPath		Path to the compiler used for TypeScript. This allows you to override the default if you need to.
AzureWebJobsDotNetReleaseCompilation	true (false when a remote debugger is attached or when running locally)	Specifies whether to use Release mode when compiling .NET code. The default is Release mode. Set to "false" to force debug compilation.
AzureWebJobsScriptRoot	On Azure, %HOME%\site\wwwroot	Specifies the path to the root directory where Functions live (i.e. where the host.json and individual function folders live). When running in Azure, will default to %HOME%\site\wwwroot.
APPINSIGHTS_INSTRUMENTATIONKEY		Specifies the Application Insights key if you're using App Insights
