Issue while using storybookjs Knobs Addon @5.3.19 in Angular 7 Workspace

[akhilesh85]

Describe the bug

When I installed story book in my angular 7 workspace with typescript@3.2.4, all the pre-installed addons such as actions and links were working fine without an errors. The moment I installed Knobs addon it started throwing errors.

To Reproduce

Steps to reproduce the behavior:

1. Create an Angular 7 workspace using npm.
2. Install latest storybook through npm.
3. Run the storybook, no errors observed and the storybook server starts successfully.
4. Stop the storybook and install latest knobs addon using npm.
5. Run the storybook again, error starts pouring.

Expected behavior

As the latest storybook does not have a dependency on typescript version, the knob addon should also not have any dependency on the Typescript version. Addon should always align to all the storybook supported versions and not define its explicit dependencies. Because of this issue, even though storybook.js is fully compatible with Angular 7 workspace, because of the Knobs addon explicit dependency on TS, the latest version of storybook.js cannot be used. I even tried adding all other latest addons of story book, all the addons worked fine in Angular 7 workspace except Knob addons.

Constrain*

I cannot upgrade my workspace to 8 as there are a lot of dependent components that I have to rework for the upgrade.

Hi Shilman,

I tried the control addon and did not find Issues while integrating it. However, I am unable to use the addon as it is throwing error. Do you have any reference guide for how to use control for angular? I found the storybook doc very hard to follow for Angular as most of the examples are for React. Is there a better approach I could take to follow the doc? As today I spent around 8 hours :(

Following are my configuration files:

Hi Shilman,

Thanks. I managed to upgrade to beta-44. When I upgraded it gave some errors. I have some .scss files in my workspace hence I had to install sass-loader css-loader and style-loader of webpack as part of preset-scss storybook presets.

On running the storybook, I got the below error:

I was able to resolve the above error in my angular 7 workspace.

I had to upgrade core-js from 2.6.11 to 3.6.5 and downgrade sass-loader from 8.0.2 to 7.3.1. In addition to this, I had to add some path entries in my tsconfig.json. zloirock/core-js#573 (comment)

I managed to get this working without using the beta release and without downgrading sass-loader, and only upgrading core-js (3.6.5)

Hi, the reason for sass-loader downgrade was that my project was throwing errors with regard to scss declartions, as it was only compatible with the lower version of sass.
