Michaelkc.Extensions.Configuration.Doppler

DopplerSDK.ConfigurationProvider adds a read-only Doppler-backed configuration provider to the standard .NET configuration pipeline.

It is designed to be used like other built-in providers: register once during startup, then bind your options as usual.

Features

  • AddDoppler(...) integration for IConfigurationBuilder / ConfigurationManager
  • Read-only secret loading from Doppler's download endpoint
  • Token-first bootstrap (DopplerToken required)
  • Optional host override and Doppler name transformer selection
  • Optional periodic reload support
  • Fail-fast startup behavior by default when Doppler loading fails

Quick start

using DopplerSDK.ConfigurationProvider;

var builder = WebApplication.CreateBuilder(args);

builder.Configuration.AddDoppler(doppler =>
{
    // DopplerToken could come from environment or user secrets
    doppler.DopplerToken = builder.Configuration["DopplerToken"];
    doppler.DopplerNameTransformer = DopplerNameTransformers.DotNet;
    // doppler.DopplerApiHost = "https://api.doppler.com"; // optional override
});

Then configure options as normal:

builder.Services.Configure<AppSettings>(builder.Configuration);

Bootstrap configuration contract

DopplerClientConfiguration fields:

  • DopplerToken (required)
  • DopplerNameTransformer (optional, defaults to dotnet)
  • DopplerApiHost (optional, defaults to https://api.doppler.com)
  • RequestTimeout (optional, defaults to 30 seconds)

Provider-level fields:

  • FailFast (optional, defaults to true)
  • ReloadInterval (optional, disabled unless set)

Security guidance

  • Do not hard-code service tokens in committed files.
  • Prefer environment variables, user secrets, or a local development-only JSON file ignored by git.
  • Treat Doppler tokens as credentials with least-privilege access.

Sample

See the SampleApp project for an end-to-end example. It also demonstrates how to load an entire appsettings.json document out of a single key using the provider.
