for .NET Core 6
To save time. There are other boilerplates on GitHub but they are huge and they became framework on top of the framework.
The goal of this boilerplate is to be easy to grasp and extend.
- User registration and authentication using JWT.
- User registration and authentication using Google OAuth2 / OIDC.
- Email verification.
- Reset password via email.
- Localization.
- Fluent validation.
- Log to database using NLog.
- Configured SendGrid.com email service (you can easily replace it with other service).
- SQLite database for local development and PostgreSQL database for production.
- Integrated Swagger (enables easy access to your REST API).
- Logs EntityFramework SQL queries to console when in development environment.
- Supports paginated response.
- Health check.
- Test project with xUnit and NSubstitute (User service has 100% test coverage).
- 100% documented (each class, method, property... is fully documented).
All settings used for development are stored in appsettings.Development.json.
You can see that AppSettings:Secret and AppSettings:SendGridApiKey are set to dummy values.
This is sensitive information and you should use environment variables to set these values.
These settings can be overriden by environment variables that use this format:
Key1__Key2... Note: keys are separated with __
You must add environment variables AppSettings__Secret and AppSettings__SendGridApiKey with their values to your operating system,
or you can replace dummy values in appsettings.Development.json (not recommended but it will work).
You might need to restart your IDE after you add environment variables.
Secret key must be at least 16 chars long.
The ASPNETCORE_ prefixed environment variables are read first for host configuration (and the prefix is stripped off), then the appsettings.json provided configuration is read. The app settings file has the final word between those two.
Environment variables without the prefix are loaded after appsettings.json provided configuration. Between those two sources, the environment variable has the final word.
Project comes with generated initial migration. There are two database contexts:
- AppDbContext (PostgreSQL database, should be used in production environment)
- DevAppDbContext (SQLite database, should be used in development environment)
To generate migration for AppDbContext use these commands:
export ASPNETCORE_ENVIRONMENT=Production
dotnet ef migrations add <REPLACE_WITH_MIGRATION_NAME> --context AppDbContext --output-dir Data/Migrations/App
To generate migration for DevAppDbContext use these commands:
export ASPNETCORE_ENVIRONMENT=Development
dotnet ef migrations add <REPLACE_WITH_MIGRATION_NAME> --context DevAppDbContext --output-dir Data/Migrations/DevApp
Note that I used export command to set the value of ASPNETCORE_ENVIRONMENT environment variable. This is Bash Shell command.
If you are using CMD (Command Prompt) then you should use the SET command.
You can request localized response by sending culture in URL or sending Accept-Language in request header.
For example
In url:
https://localhost:5001/User/authenticate?culture=bs
In header:
Accept-Language: bs
Users can login with their Google account.
You can easily setup any other OAuth2/OIDC identity provider, such as Facebook. Just search for "oidc-google" in the code and see how it is done.
To configure login with Google, make sure that environment variables AppSettings__OidcGoogleClientId and AppSettings__OidcGoogleClientSecretare are set.
To start login flow, navigate to https://localhost:5001/ExternalUser/loginWithGoogle. This HTTP request must be done in web browser!
Flow goes like this:
- User gets redirected to Google.com
- User continues with login on Google domain
- After login user is redirected back to our backend
- We check if user is already in our db (if not we add him)
- We create our own token and send it back to user
I did not use Identity system as it introduces too much complexity for small or medium sized projects and for people starting with ASP.NET.
