Set up Storybook for Angular Projects
This guide will walk you through setting up Storybook for Angular projects in your Nx workspace.
Set up Storybook in your workspaceYou first need to set up Storybook for your Nx workspace, if you haven't already. You can read the Storybook plugin overview guide to get started.
Generate Storybook Configuration for an Angular project
You can generate Storybook configuration for an individual Angular project by using the @nx/angular:storybook-configuration generator, like this:
❯
nx g @nx/angular:storybook-configuration project-name
Auto-generate Stories
The @nx/angular:storybook-configuration generator has the option to automatically generate *.stories.ts files for each component declared in the library. The stories will be generated using Component Story Format 3 (CSF3).
1<some-folder>/
2├── my.component.ts
3└── my.component.stories.ts
4If you add more components to your project, and want to generate stories for all your (new) components at any point, you can use the @nx/angular:stories generator:
❯
nx g @nx/angular:stories --project=<project-name>
Let's take for a example a library in your workspace, under libs/feature/ui, called feature-ui. This library contains a component, called my-button.
The command to generate stories for that library would be:
❯
nx g @nx/angular:stories --project=feature-ui
and the result would be the following:
1<workspace name>/

23Example Files
Let's take for example a library in your workspace, under libs/feature/ui, called feature-ui with a component, called my-button.
Let's say that the template for that component looks like this:
1<button [disabled]="disabled" [ngStyle]="{ 'padding.px': padding }">
2 {{ text }}
3</button>
4and the component looks like this:
1import { Component, Input } from '@angular/core';
2
3({
4 selector: 'feature-ui-my-button',
5 standalone: true,
6 templateUrl: './my-button.component.html',
7 styleUrls: ['./my-button.component.css'],
8})
9export class MyButtonComponent {
10 () text = 'Click me!';
11 () padding = 10;
12 () disabled = true;
13}
14Story file
The @nx/angular:storybook-configuration generator would generate a Story file that looks like this:
1import type { Meta, StoryObj } from '@storybook/angular';
2import { MyButtonComponent } from './my-button.component';
3import { within } from '@storybook/testing-library';
4import { expect } from '@storybook/jest';
5
6const meta: Meta<MyButtonComponent> = {
7 component: MyButtonComponent,
8 title: 'MyButtonComponent',
9};
10export default meta;
11type Story = StoryObj<MyButtonComponent>;
12
13export const Primary: Story = {
14 args: {
15 text: 'Click me!',
16 padding: 10,
17 disabled: true,
18 },
19};
20
21export const Heading: Story = {
22 args: {
23 text: 'Click me!',
24 padding: 10,
25 disabled: true,
26 },
27 play: async ({ canvasElement }) => {
28 const canvas = within(canvasElement);
29 expect(canvas.getByText(/my-button works!/gi)).toBeTruthy();
30 },
31};
32Notice the interaction test on the second story, inside the play function. This just tests if the default text that appears on generated components exists in the rendered component. You can edit this test to suit your needs. You can read more about interaction tests here.
