RobotsTxtMiddleware

From version 2.0 I've dropped support for .NET Core versions prior to 3.1 and made a huge breaking change by adding a IRobotsTxtProvider interface seperate from the middleware to handle configuration.

A Robots.txt middleware for ASP.NET Core. Why is this needed you ask? Because if you need to add dynamic values (such as a configured url from your CMS) you'll need some sort of code to handle that, and this makes it easy.

Installation

NuGet

PM> Install-Package RobotsTxtCore

.Net CLI

> dotnet add package RobotsTxtCore

Usage

To specify multiple rules with the fluent interface makes it really easy.

public void ConfigureServices(IServiceCollection services) {
    services.AddStaticRobotsTxt(builder =>
        builder
            .AddSection(section =>
                section
                    .AddComment("Allow Googlebot")
                    .AddUserAgent("Googlebot")
                    .Allow("/")
                )
            .AddSection(section =>
                section
                    .AddComment("Disallow the rest")
                    .AddUserAgent("*")
                    .AddCrawlDelay(TimeSpan.FromSeconds(10))
                    .Disallow("/")
                )
            .AddSitemap("https://example.com/sitemap.xml")
    );
}

public void Configure(IApplicationBuilder app) {
    app.UseRobotsTxt();
}

Output

# Allow Googlebot
User-agent: Googlebot
Allow: /

# Disallow the rest
User-agent: *
Disallow: /
Crawl-delay: 10

Sitemap: https://example.com/sitemap.xml

Or if you just want to deny everyone.

public void ConfigureServices(IServiceCollection services) {
    services.AddStaticRobotsTxt(builder =>
        builder
            .DenyAll()
    );
}

public void Configure(IApplicationBuilder app) {
    app.UseRobotsTxt();
}

Output

User-agent: *
Disallow: /
