Usage

Register and configure Rate limiting services(rules)

Example:

builder.Services.
    AddFixedWindow(configure =>
    {
        configure.RuleConditions = new List<Func<AccessToken, bool>>
        {
            token => token.Region == Region.us,
            token => !string.IsNullOrEmpty(token.UserId)
        };

        configure.Limit = 10;
        configure.WindowSize = TimeSpan.FromMinutes(2);
    }).
    AddTimeBasedRateLimiting(configure =>
    {
        configure.RuleConditions = new List<Func<AccessToken, bool>>
        {
            token => token.Region == Region.us || token.Region == Region.eu,
            token => !string.IsNullOrEmpty(token.UserId)
        };

        configure.MinTimeBetweenRequests = TimeSpan.FromSeconds(10);
    });

Rules are applied based on conditions. If the condition is not specified then it applies to all requests

    configure.RuleConditions = new List<Func<AccessToken, bool>>
    {
        token => token.Region == Region.us,
        token => !string.IsNullOrEmpty(token.UserId)
    };

Set up the RateLimitMiddleware

Add the RateLimit middleware to your Configure method in the Startup class or directly into your IWebHostBuilder.

Example:

app.UseRateLimiting();
