Skill: Create New Component

Create a new React component following project conventions.

Usage

/new-component <ComponentName> [directory]

Prerequisites

This should typically be done as part of implementing a feature. Ensure:

• A feature file exists that requires this component
• Step definitions reference the component's behavior

Steps

1. Create the component file at src/components/{directory}/{ComponentName}.jsx
2. Use functional component with hooks
3. Define PropTypes for type checking
4. Export the component as default
5. Add data-testid attributes for acceptance testing

Template

// src/components/{directory}/{ComponentName}.jsx

import { useState } from 'react';
import PropTypes from 'prop-types';

function {ComponentName}({ prop1, prop2 }) {
  // Component logic here

  return (
    <div data-testid="{component-name}">
      {/* Component content */}
    </div>
  );
}

{ComponentName}.propTypes = {
  prop1: PropTypes.string.isRequired,
  prop2: PropTypes.number
};

{ComponentName}.defaultProps = {
  prop2: 0
};

export default {ComponentName};

Naming Conventions

• Component files: PascalCase (StepEditor.jsx)
• Test IDs: kebab-case (data-testid="step-editor")
• CSS classes: kebab-case with BEM (step-editor__input)

Test ID Guidelines

Add data-testid attributes for elements that acceptance tests need to interact with:

<button data-testid="add-step-button">Add Step</button>
<input data-testid="step-name-input" />
<div data-testid="metrics-dashboard">...</div>

Integration with Acceptance Tests

Components should be designed to support acceptance testing:

// In step definitions
When('I click the add step button', async function () {
  const button = await this.page.$('[data-testid="add-step-button"]');
  await button.click();
});

Then('I should see the step editor', async function () {
  const editor = await this.page.$('[data-testid="step-editor"]');
  expect(editor).to.exist;
});
