How To Control Storybook Angular To Show Only INPUTS In Controls

Introduction

Storybook is a popular tool for building and testing user interface components in isolation. When working with Angular components, Storybook provides a powerful way to visualize and interact with your components. However, by default, Storybook displays a wide range of information about your components, including INPUTS, PROPERTIES, METHODS, and OUTPUTS. In this article, we will explore how to control Storybook Angular to show only INPUTS in controls.

Understanding Storybook Angular

Before we dive into the details of controlling Storybook Angular, let's take a brief look at what Storybook Angular is and how it works. Storybook Angular is a plugin for Storybook that allows you to build and test Angular components in isolation. It provides a powerful way to visualize and interact with your components, making it easier to develop and test them.

Creating a Storybook for an Angular Component

To create a Storybook for an Angular component, you need to install the @storybook/angular package and configure it in your project. Here's an example of how to create a Storybook for an Angular component with @Input and @Output variables:

// my-component.ts
import { Component, Input, Output, EventEmitter } from '@angular/core';

@Component(
selector 'app-my-component',
template:     <p>My Component</p>     <button (click)="onClick()">Click me!</button>  ,
)
export class MyComponent {
@Input() name: string;
@Output() clickEvent = new EventEmitter<void>();


onClick() {
this.clickEvent.emit();
}
}


// my-component.stories.ts
import { moduleMetadata, storiesOf } from '@storybook/angular';
import { MyComponent } from './my-component';

storiesOf('My Component', module)
  .add('default', () => ({
    component: MyComponent,
    props: {
      name: 'John Doe',
    },
  }));

Default Storybook Controls

By default, Storybook displays a wide range of information about your components, including INPUTS, PROPERTIES, METHODS, and OUTPUTS. Here's an example of what the default Storybook controls look like for the MyComponent:

**My Component**
---------------

    

  • INPUTS

      

    • name: John Doe
      • 

    

    • 

  • PROPERTIES

      

    • clickEvent: EventEmitter&lt;void&gt;
      • 

    

    • 

  • METHODS

      

    • onClick(): void
      • 

    

    • 

  • OUTPUTS

      

    • clickEvent: EventEmitter&lt;void&gt;

Controlling Storybook Angular to Show Only INPUTS

To control Storybook Angular to show only INPUTS in controls, you need to use the decorators option in your Storybook configuration. Here's an example of how to do it:

// my-component.stories.ts
import { moduleMetadata, storiesOf } from '@storybook/angular';
import { MyComponent } from './my-component';

storiesOf('My Component', module)
.addDecorator(
moduleMetadata(
declarations [MyComponent],
imports: [],
)
)
.add('default', () => (
component MyComponent,
props: {
name: 'John Doe',
,
decorators: [

type 'story',
name: 'My Component',
props: {
controls: {
expanded: true,
knobs: {
inputs: {
name: {
type: 'text',
label: 'Name',
,
},
},
},
},
},
],
}));

In this example, we're using the decorators option to add a new decorator to our Storybook configuration. The decorator is set to story type and has a name property set to My Component. We're also setting the controls property to an object that contains the expanded and knobs properties. The knobs property is set to an object that contains the inputs property, which is set to an object that contains the name property.

Resulting Storybook Controls

After applying the decorator, the resulting Storybook controls will look like this:

**My Component**
---------------

    

  • INPUTS

      

    • name: John Doe

As you can see, the Storybook controls now only show the INPUTS, and the PROPERTIES, METHODS, and OUTPUTS are no longer displayed.

Conclusion

In this article, we explored how to control Storybook Angular to show only INPUTS in controls. We learned how to create a Storybook for an Angular component with @Input and @Output variables, and how to use the decorators option in our Storybook configuration to customize the controls. By following the steps outlined in this article, you can easily control Storybook Angular to show only the INPUTS in controls, making it easier to develop and test your Angular components.

Additional Tips and Tricks

Here are some additional tips and tricks to help you get the most out of Storybook Angular:

  • Use the moduleMetadata decorator to declare your components and imports.
  • Use the storiesOf function to create a new storybook for your component.
  • Use the add method to add a new story to your storybook.
  • Use the decorators option to customize the controls.
  • Use the controls property to specify the controls that should be displayed.
  • Use the expanded property to specify whether the controls should be expanded or collapsed.
  • Use the knobs property to specify the knobs that should be displayed.
  • Use the inputs property to specify the INPUTS that should be displayed.

We learned how to create a Storybook for an Angular component with @Input and @Output variables, and how to use the decorators option in our Storybook configuration to customize the controls. In this article, we'll answer some frequently asked questions about controlling Storybook Angular to show only INPUTS in controls.

Q: What is the purpose of the decorators option in Storybook Angular?

A: The decorators option in Storybook Angular is used to customize the controls that are displayed for a component. By using the decorators option, you can specify which controls should be displayed, and how they should be displayed.

Q: How do I use the decorators option to customize the controls?

A: To use the decorators option to customize the controls, you need to add a new decorator to your Storybook configuration. The decorator should be set to story type, and should contain the controls property. The controls property should be set to an object that contains the expanded and knobs properties.

Q: What is the difference between the expanded and knobs properties?

A: The expanded property is used to specify whether the controls should be expanded or collapsed. The knobs property is used to specify the knobs that should be displayed.

Q: How do I specify the INPUTS that should be displayed?

A: To specify the INPUTS that should be displayed, you need to add a new property to the knobs object. The property should be set to an object that contains the INPUTS that should be displayed.

Q: Can I customize the appearance of the controls?

A: Yes, you can customize the appearance of the controls by using the decorators option. You can specify the layout, colors, and other visual properties of the controls.

Q: Can I use the decorators option to customize the controls for multiple components?

A: Yes, you can use the decorators option to customize the controls for multiple components. You can add multiple decorators to your Storybook configuration, each with its own set of controls.

Q: How do I troubleshoot issues with the decorators option?

A: To troubleshoot issues with the decorators option, you can check the Storybook logs for errors. You can also use the Storybook debugger to inspect the controls and identify any issues.

Q: Can I use the decorators option with other Storybook features?

A: Yes, you can use the decorators option with other Storybook features, such as the add method and the storiesOf function.
