I have an Angular library project where I have a lot of components that I use in a handful of Angular applications.

Now I want to start testing these components using Cypress component testing. Setting up Cypress with an Angular application is super easy, but trying to do it for a library project is definitely not.

I don’t really have any code to show as all my efforts are leading to the same error which is:

Error: Could not resolve "@angular-devkit/build-angular/src/webpack/configs/common.js". Do you have "@angular-devkit/build-angular" and "@angular-devkit/core" installed?

I’ve tried setting Cypress up both using the @cypress/schematic and by using npm install cypress --save-dev, to no avail.

I stumbled upon this github issue while trying to find information on how to accomplish what I want. Which talks about a library project needing an application set up in order to make it work but I have no clue how to do that and there are no examples provided either.

If anyone have succeeded in setting this up I would love some guidance!

I currently use Angular version 18 and Cypress version 13.
