How to add a new Module to existing Solution #80

4 years ago Question

Hi. I created a new solution for my Main project and now I'm trying to add a new Module to it. My solution uses Angular and I'm creating the new module with --no-ui so that I can then create the Angular modules separate.

I added the new module to a sub-folder of the solution and added Existing Project to the main solution like it was suggested in https://support.abp.io/QA/Questions/3 below.

Hi,

Every module can be a separate solution (like we did for the modules) or you can develop it under a single Visual Studio solution (for example, in the microservice demo, we've included a product module into the solution).

I suggest you to go with a single solution at the beginning since it is easier to develop, test, run and maintain. You know, in a single solution, you can cross reference projects. Assuming you will create your module as layered (like this), your application's domain layer should depend on the module's domain layer and so on (as a good practice, but you don't have to do). Also, add standard DependsOn attribute (see the document) when you add a project reference.

You can create a new module (using abp new MyProductName.MyModuleName -t module-pro - see), then add its projects to the application's solution then add references and dependson attributes. In the future, we will also automate this.

For the UI part, you can investigate the Angular UI modules we've created to understand how a module is developed. We are using them as NPM packages in the main application, however it may not be practical in development. @mehmet can write you more about that.

My solution now has the following structure.

I then went to the main Gmcs.Themis.HttpApi.Host and added the depends on the new module

Everything compiles and Runs, and the new methods for the Module display in Swagger but when i try to execute it fails and the following error is added to the Log.

What an I missing?

Another option is, does anyone have a sample solution with more than one module being used using Angular?
