Storybook has integrated Ivy support since v6.3 and this addon is no longer needed.

Storybook Addon Angular Ivy

This addon configures Storybook for Angular to use the new Angular Ivy renderer instead of the ViewEngine that Storybook uses by default.

Installation

This addon installs just like any other Storybook addon:

npm install --save-dev storybook-addon-angular-ivy

Then add it to your .storybook/main.js addons field:

module.exports = {
  addons: ["storybook-addon-angular-ivy"],
};

That's it! The first time you run it on a new project, the addon will run the angular compiler ngcc on your node_modules folder.
