EnvInfo.MVC 8.0.0.1

EnvInfo

EnvInfo is a collection of Mvc/RazorPages tag helpers and DotVVM controls that provides environment information for your application. It is useful for identifing between different environments like Development, Staging, and Production.

Features

• display environment name (e.g., DEV, STAG, PROD) based on the current environment
• ability to change environment name or visility using configuration
• display Bootstrap breakpoint name (e.g., xs, sm, md, lg, xl) based on the current screen width
• ability to change predefined styles using custom css

Usage

Install nuget package for each UI framework you use in your project. Then register required service in Program.cs or Startup.cs file

builder.Services.AddEnvInfo();

By default, the Name is derived from the environment name and Visible is set to true for the development environment. Then tries to load the configuration section EnvInfo and set the values.

"EnvInfo": {
    "Name": "ALPHA",
    "Visible": true
}

You can provide custom configuration section.

services.AddEnvInfo(Configuration.GetSection("App.EnvInfo"));

Or you can override Name directly in code

builder.Services.AddEnvInfo("APLHA");

Or simply provide custom configuration object

services.AddEnvInfo(new EnvInfoOptions
{
    Name = "CUSTOM",
    Visible = true
});
