Sentry Giraffe F# Demo

This is an example Giraffe web application that demonstrates how to integrate Sentry for error reporting.

• To install Sentry's ASP.NET Core integration, you can use NuGet:

dotnet add package Sentry.AspNetCore

...or Paket:

paket add Sentry.AspNetCore

...or add it directly into your .fsproj file:

<PackageReference Include="Sentry.AspNetCore" Version="3.0.0" />

• In order to integrate with Sentry, simply add a call to UseSentry() when setting up the web host:

[<EntryPoint>]
let main _ =
    WebHost.CreateDefaultBuilder()
        .ConfigureServices(configureServices)
        .Configure(configureApp)
        .UseSentry()
        .Build()
        .Run()
    0

The example in Program.fs showcases how Sentry can automatically catch and report unhandled exceptions and also how you can enrich sent data with additional information. For an F# example that goes more in-depth in the Sentry SDK's API, please check out the base F# demo.

Running the demo

To run the demo, take the following steps:

0. Make sure that the latest .NET SDK is installed.
1. Go into appsettings.json and change the Dsn value to match your own DSN.
2. Build and run the demo with dotnet run -c Release (or use your IDE).
3. You should see the following debug output in the console:
