This is a REST API sample app which demonstrate interactions with MongoDB server. The REST API is built using C#, ASP .NET Core & Csharp mongodb Driver

When you run the sample, a HTTP server will run and host the program on port 5000. The program exposes /api/v1/gamingPc resource path where it returns a list of JSON objects when you browse the path or invoke it through using curl or Postman.

• C# programming language.
• ASP .NET Core and Web API.
• MongoDB Driver for C#.

• The demo's data. You could grab it from here: https://github.com/WendySanarwanto/data-for-researches/ and import it into your mongodb server.

• Ensure that you have setup .NET Core in your machine. If not, follow the instruction in here: https://www.microsoft.com/net/core#linuxubuntu
• Pull this repository into your local machine through running git clone https://github.com/WendySanarwanto/demo-api-aspnetcore-mongodb.git command in your CLI terminal.
• Go to inside the cloned repository's directory, then run dotnet build -c Release command.
• Run dotnet run ./bin/Release/netcoreapp1.1/demo-api-mongodb.dll command to start the application.
• Open your browser then browse to http://localhost:5000/api/v1/gamingPc path. Confirm that you will get a list of JSON objects.

• The unit test, I have not done it yet.
• Creating POST, PUT , DELETE resources. I welcome for anyone whom like to work on this parts and looking forward for your pull requests.

• Supports for Asynchronous process on handling incoming POST, PUT, DELETE requests on API side & the mongo driver's side , using async await & Task.

I benchmarked the GET resource path using wrk HTTP benchmarking tool (https://github.com/wg/wrk) using this command wrk -c 256 -t 32 -d1m http://localhost:5000/api/v1/gamingpc ( 256 connections, 32 threads, run the test for 1 minute). Here are the results:

• 1st run: Requests/sec: 1258.68. Served 75638 requests, where 495 requests were timed out and 30447 calls were received as non-2xx or 3xx responses.
• 2nd run: Requests/sec: 1229.81. Served 73912 requests, where 1458 requests were timed out and 31008 calls were received as non-2xx or 3xx responses
• 3rd run: Requests/sec: 1133.19. Served 68100 requests, where 437 requests were timed out and 21987 calls were received as non-2xx or 3xx responses

THe machine's configuration that is used for running the benchmark are listed as follow:

• CPU: Intel i5-6600 Skylake
• RAM: 16 GB DDR 4 (2x8 GB)
• Motherboard: ASUS Z170-K Intel Z170 Chipset
• OS: Linux Ubuntu 16.04.1 LTS
• Disk: SSD 480 GB Corsair Neutron GTX
