Startup Template AngularEdit on Github
The easiest way of starting a new project using ABP with ASP.NET Core with Angular is to create a template on templates page. Remember to check "Include module zero". After creating and downloading your project, follow below steps to run your application.
ASP.NET Core Application
- Open your solution on Visual Studio 2017 v15.3.5+ and build the solution.
- Select the 'Web.Host' project as startup project.
- Open Package Manager Console and run Update-Database command to create your database (ensure that Default project is selected as .EntityFrameworkCore in the Package Manager Console window).
- Run the application. It will show swagger-ui if it is successfull:
In this template, multi-tenancy is enabled by default. You can disable it in Core project's module class if you don't need.
If you have problems with running the application, please try close and open your Visual Studio again. It sometimes fail on first package restore.
Angular application needs to following tools be installed:
- nodejs 6.9+ with npm 3.10+
- Typescript 2.0+
We used angular-cli to develop the Angular application.
Open a command prompt, navigate to angular folder which contains *.sln file and run the following command to restore npm packages:
Notice that npm install may show some warn messages, which is not related to our solution and generally it's not a problem. The solution can also configured to work with yarn and we suggest to use it if available on your computer.
Run The Application
In your opened command prompt, run the following command:
Once the application compiled, you can browse http://localhost:4200 in your browser. Be sure that Web.Host application is running at the same time. When you open the application, you will see the login page:
Angular client app has also HMR (Hot Module Replacement) enabled. You can use the following command (instead of npm start) to enable HMR on development time:
npm run hmr
Now you can login the application using default credentials. User name is 'admin' and password is '123qwe' as default. If you want to login as a tenant, first switch to that tenant in login page. There is a tenant named "Default" by default. Once you login successfully, you will see a dashboard:
This dashboard is just for demonstration and to be a base for your actual dashboard.
Deployment of Angular Application
We used angular-cli tooling to build Angular solution. You can use ng build command to publish your project. It publishes to dist folder by default. Then you can host this folder on IIS or any web server you like.
Solution Details & Other Features
Token Based Authentication
If you want to consume APIs/application services from a mobile application, you can use token based authentication mechanism just like we do it for Angular client. Startup template includes JwtBearer token authentication infrastructure.
Here, Postman (chrome extension) will be used to demonstrate requests and responses.
Just send a POST request to http://localhost:21021/api/TokenAuth/Authenticate with Context-Type="application/json" header as shown below:
We sent values usernameOrEmailAddress and password. As seen above, result property of returning JSON contains the token and expire time (which is 24 hours by default and can be configured). We can save it and use for next requests.
**About Multi Tenancy
**API will work as host users by default. You can send Abp.TenantId header value to work with a specified tenant. It's an integer value and 1 for default tenant by default.
After authenticate and get the token, we can use it to call any authorized action. All application services are available to be used remotely. For example, we can use the User service to get a list of users:
Just made a GET request to http://localhost:21021/api/services/app/user/getAll with Content-Type="application/json" and **Authorization="Bearer *your-***auth-token ". All functionality available on UI is also available as API.
Migrator Console Application
Startup template includes a tool, Migrator.exe, to easily migrate your databases. You can run this application to create/migrate host and tenant databases.
This application gets host connection string from it's own appsettings.json file. It will be same in the appsettings.json in the .Web.Host project at the beggining. Be sure that the connection string in config file is the database you want. After getting host connection sring, it first creates the host database or apply migrations if it does already exists. Then it gets connection strings of tenant databases and runs migrations for those databases. It skips a tenant if it has not a dedicated database or it's database is already migrated for another tenant (for shared databases between multiple tenants).
You can use this tool on development or on product environment to migrate databases on deployment, instead of EntityFramework's own tooling (which requires some configuration and can work for single database/tenant in one run).
Startup template includes test infrastructure setup and a few tests under the .Test project. You can check them and write similar tests easily. Actually, they are integration tests rather than unit tests since they tests your code with all ASP.NET Boilerplate infrastructure (including validation, authorization, unit of work...).
This project template is developed as open source and free under Github: https://github.com/aspnetboilerplate/module-zero-core-template
