Creating an Angular Dropdown Component with Storybook: A Guided Tutorial with ChatGPT Assistance

Creating a dropdown component in Angular using Storybook involves a few steps. Below is a basic guide on how to do it, including how ChatGPT can be used to assist you.

Prerequisites

Before we start, make sure you have the following installed:

• Node.js and npm
• Angular CLI
• Storybook for Angular

If you don’t have these installed, you can download them from their respective websites and install them on your machine.

Step 1: Create a new Angular project

You can create a new Angular project using the Angular CLI. To do so, open a terminal and run the following command:

ng new dropdown-storybook

Step 2: Install Storybook

Navigate into your new Angular project directory and install Storybook using the following commands:

cd dropdown-storybook
npx sb init

Step 3: Create a Dropdown Component

You can create a new Dropdown component using the Angular CLI. Run the following command:

ng g c Dropdown

This will create a new Dropdown component in your project. The component will include a TypeScript file, an HTML file, and a CSS file.

Step 4: Create a Story for the Dropdown Component

In the ‘stories’ folder, create a new file called dropdown.stories.ts. This will be the story for our Dropdown component.

Here is a basic example of what your dropdown story might look like:

import { Meta, Story } from '@storybook/angular';
import { DropdownComponent } from './dropdown.component';

export default {
  title: 'Example/Dropdown',
  component: DropdownComponent,
  parameters: {
    docs: {
      autodocs: true, // Opt-in to autodocs
      description: {
        component: 'This is a dropdown component', // Component description
      },
    },
  },
} as Meta;

// Primary Story
export const Primary: Story<DropdownComponent> = (args) => ({
  component: DropdownComponent,
  props: args,
  parameters: {
    docs: {
      story: { inline: true }, // Render the story in an iframe
      canvas: { sourceState: 'shown' }, // Start with the source open
      source: { type: 'code' }, // Forces the raw source code
    },
  },
});

Primary.args = {
  // Define the default arguments here
  options: ['Item 1', 'Item 2', 'Item 3'],
};

// Add JSDoc for story descriptions
/**
 * This is a primary dropdown story.
 */
Primary.storyName = 'Primary';

Angular Storybook v7 - A ShareGPT conversation

• Chatgpt just has one mistake and you should change :

  items: ['Item 1', 'Item 2', 'Item 3'],

to

  options: ['Item 1', 'Item 2', 'Item 3'],

Conclusion

That’s it! You’ve created a dropdown component in Angular using Storybook with the help of ChatGPT. You can now run Storybook and see your component in action. To do so, use the following command:

npm run storybook

This will open a new browser window where you can interact with your component in an isolated environment. It’s a great way to develop and test individual components. Enjoy your Storybook journey!
