Redis REST with WCF

This blog presents a Redis REST server using Microsoft Window Communication Foundation (WCF).
The servers is written in F#.
The server is tested with a Web browser HTML/javascript example.
The security features is not included yet and it will be address in future blog.

Redis for Windows is available for download from Microsoft Open Technologies Inc. at  https://github.com/MSOpenTech.. 

The Redis server was started using redis-server.exe at a command prompt window. 

The tests were performed using F# interactive inside Visual Studio Express 2012 for Web.

The Redis .NET driver used was from http://code.google.com/p/booksleeve/

MongoDB tests with F#

 

 This post reports several results related to testing MondoDB for Windows with F# and more specifically with F# interactive.  

 

MongoDB for Windows is available for download from 10gen Inc. at  http://www.mongodb.org/downloads.   

 

The MongoDB server was started using mongod.exe at a command prompt window.  

 

The tests were performed using F# interactive inside Visual Studio Express 2012 for Web.  

 

The documents uses MongoDB .NET driver supported by 10gen Inc. and documented at  http://www.mongodb.org/display/DOCS/CSharp+Language+Center. 

 

The tests were based on the C# examples at http://www.mongodb.org/display/DOCS/CSharp+Driver+Tutorial.

The Redis server was started using redis-server.exe at a command prompt window. 

 

The tests were performed using F# interactive inside Visual Studio Express 2012 for Web. 

 

The Redis .NET driver used was from ServiceStack (https://github.com/ServiceStack/ServiceStack.Redis ) and downloaded from https://github.com/ServiceStack/ServiceStack.Redis/downloads . 

The tests were based on the C# example from https://github.com/ServiceStack/ServiceStack.Redis/tree/master/tests/ServiceStack.Redis.Tests/Examples . 

 

The following script shows the tests:

 

// Redis - example from

// System

Three-tier web application with F# and javascript

In the previous posts, I described several examples of services using F# with WCF.

 In this post, and in a series of future ones, I will describe a high efficient web application technology using three-tier architecture: host server, database server and web browser interface.

The software resources used in these posts are:

·        Host server:

o   F# language

o   Windows Communication Foundation (WCF) – services oriented application framework

·        Database server:

o   SQL Server Compact – database engine

o   Entity Framework – object relational mapper

o   F# type providers – information rich application component

·        Web client:

o   HTML5 – web markup language

o   javascript – web scripting language

o   jquery – javascript library

o   jqWidgets – web user interface library

o   knockoutjs –model-view-view-model javascript library

In my opinion, these set of software technologies represent the state-of-art available for web applications. The advantages are:

·        All software, except the jqWidgets and knockoutjs, are supplied by Microsoft

·        Microsoft Visual Studio is the only development tool required

·        All software, except jqWidgets, are free if you own the Window Operation System

·        Host server has high performance due to compiled code and the use of REST and Json

·        Application can be self-hosted or part of a server application as IIS

·        No SQL commands are needed to access the database

·        Client is available in all devices that support HTML5

·        Several components are used to hide complexity resulting in application with few lines of code

A user authentication web application is presented as an example.
