LaunchDarkly Streaming JSON for .NET

Documentation

Overview

The LaunchDarkly.JsonStream library implements a streaming approach to JSON encoding and decoding designed for efficiency at high volume, assuming a text encoding of UTF8. Unlike reflection-based frameworks, it has no knowledge of structs or other complex types; you must explicitly tell it what values and properties to write or read. It was implemented for the LaunchDarkly server-side .NET SDK and LaunchDarkly client-side .NET SDK, but may be useful in other applications.

Supported .NET versions and platform differences

This version of the SDK is built for the following targets:

  • .NET 6.0
  • .NET 5.0
  • .NET Core 3.1
  • .NET Core 2.1
  • .NET Framework 4.5.2
  • .NET Framework 4.6.1 (also works on .NET Framework 4.7)
  • .NET Standard 2.0 (used on other platforms such as Xamarin)

System.Text.Json support

All builds of LaunchDarkly.JsonStream except for .NET Framework 4.5.2 and .NET Standard 2.0 make use of the System.Text.Json API, which is built into the standard runtime library for .NET Core 3.x and .NET 5.x and is imported as a NuGet package on other platforms. Any types that use the LaunchDarkly.JsonStream.JsonStreamConverter attribute will automatically be recognized by System.Text.Json‘s reflection-based APIs.

The .NET Framework and .NET Standard 2.0 builds of LaunchDarkly.JsonStream use a different portable implementation that is not as fast as System.Text.Json, but still highly efficient. System.Text.Json is not available for .NET Framework 4.5.2. It is available for .NET Standard 2.0, but the .NET Standard 2.0 target of LaunchDarkly.JsonStream is also used in Xamarin, and System.Text.Json currently has compatibility problems with Xamarin.

The external API of the library is the same regardless, so portable JSON encoding/decoding logic can be written against LaunchDarkly.JsonStream without needing to know the target platform.

Signing

The published version of this assembly is both digitally signed by LaunchDarkly and strong-named. Building the code locally in the default Debug configuration does not sign the assembly and does not require a key file. The public key file is in this repository at LaunchDarkly.JsonStream.pk as well as here:

About LaunchDarkly

  • LaunchDarkly is a continuous delivery platform that provides feature flags as a service and allows developers to iterate quickly and safely. We allow you to easily flag your features and manage them from the LaunchDarkly dashboard. With LaunchDarkly, you can:
    • Roll out a new feature to a subset of your users (like a group of users who opt-in to a beta tester group), gathering feedback and bug reports from real-world use cases.
    • Gradually roll out a feature to an increasing percentage of users, and track the effect that the feature has on key metrics (for instance, how likely is a user to complete a purchase if they have feature A versus feature B?).
    • Turn off a feature that you realize is causing performance problems in production, without needing to re-deploy, or even restart the application with a changed configuration file.
    • Grant access to certain features based on user attributes, like payment plan (eg: users on the ‘gold’ plan get access to more features than users in the ‘silver’ plan). Disable parts of your application to facilitate maintenance, without taking everything offline.
  • LaunchDarkly provides feature flag SDKs for a wide variety of languages and technologies. Check out our documentation for a complete list.
