Boilerplate of API in .NET Core 3.1

Travis CI	GitHub	Codecov

Boilerplate is a piece of code that helps you to quickly kick-off a project or start writing your source code. It is kind of a template - instead of starting an empty project and adding the same snippets each time, you can use the boilerplate that already contains such code.

Source code contains

1. Autofac
2. Swagger + Swashbuckle
3. EF Core
   • MySQL provider from Pomelo Foundation
   • MsSQL from Microsoft
4. Tests
   • Integration tests with InMemory database
   • Unit tests
5. Code quality
   • EditorConfig (.editorconfig)
   • Analizers (Microsoft.CodeAnalysis.Analyzers, Microsoft.AspNetCore.Mvc.Api.Analyzers)
   • Rules
   • Code coverage
     • Coverlet
     • Codecov
6. Docker
   • Dockerfile
   • Docker-compose
     • mysql:8 with DB initialization
     • mcr.microsoft.com/mssql/server:2017-latest with DB initialization
     • netcore-boilerplate:local
7. Serilog
   • Sink: Async
   • Enrich: CorrelationId
8. DbUp as a db migration tool
9. Continuous integration
   • Travis CI (.travis.yml)
   • GitHub Actions (dotnetcore.yml)

How to adopt to your project

Generally it is totally up to you! But in case you do not have any plan, You can follow below simple steps:

1. Download/clone/fork repository
2. Remove components and/or classes that you do not need to
3. Rename files (e.g. sln, csproj, ruleset), folders, namespaces etc.
4. Give us a star!

Build the solution

Just execute dotnet build in the root directory, it takes HappyCode.NetCoreBoilerplate.sln and build everything.

Start the application

Standalone

At first, you need to have up and running MySQL and MsSQL database servers on localhost with initialized database by mysql script and mssql script.

Then the application (API) can be started by dotnet run command executed in the src/HappyCode.NetCoreBoilerplate.Api directory. By default it will be available under http://localhost:5000, but keep in mind that documentation is available under http://localhost:5000/swagger/.

Docker (recommended)

Just run docker-compose up command in the root directory and after successful start of services visit http://localhost:5000/swagger/.

Migrations

When the entire environment is up and running, you can additionally run a migration tool to add some new schema objects into MsSQL DB. To do that, go to src/HappyCode.NetCoreBoilerplate.Db directory and execute dotnet run command.

Run unit tests

Run dotnet test command in the root directory, it will look for test projects in HappyCode.NetCoreBoilerplate.sln and run them.
