Butterfly.Server

The Everything is Real-Time C# Backend for Single Page Applications

Overview

Butterfly.Server is a set of packages that can be used separately or can be used together to create integrated solutions to create modern web apps with a C# backend. The purpose of this repo is to show examples of how to use the components together.

Butterfly.Server is especially well suited to powering SPAs (single page applications) by providing...

• A RESTlike API enabling clients to receive static data and perform actions
• A Subscription API enabling clients to automatically receive real-time updates when data changes
• A Database API that avoids object-relational mappings and publishes data change events
• A Messaging API that provides a consistent API to send emails and texts

Butterfly.Server consists of the following components...

• Butterfly.Auth - Authenticate clients using Butterfly.Db and Butterfly.Web
• Butterfly.Client - Clients (javascript and .NET) that can subscribe real-time updates from a Butterfly.Web server
• Butterfly.Db - Reactive database SELECTs for popular relational databases
• Butterfly.Message - Send emails and text messages via the same API
• Butterfly.Util - Collection of utility classes and methods
• Butterfly.Web - Simple RESTlike and Subscription API server

Butterfly.Server...

• Targets .NET Framework 2.1 (.NET Core 3.0)
• Fully supports async/await
• Does not depend on ASP.NET
• Does not use polling for real-time updates

Examples

The following examples are a good way to understand how to use the Butterfly.Server components...

• Butterfly.Example.Contacts - Shows a Vue.js web client managing a set of contacts by interacting with a Butterfly.Server
• Butterfly.Example.DbEvents - Shows how to perform basic database operations and see generated data events
• Butterfly.Example.Echo - Shows a "Hello World" alert box in a client
• Butterfly.Example.RealtimeStreamingChart - Shows a client with a real-time streaming chart updated from a server (uses Smoothie Charts)
• Butterfly.Example.Todos - Shows a Vue.js web client managing a set of to-dos by interacting with a Butterfly.Server
