experience-lwc-generate

Lightning Web Components development skill with PICKLES architecture methodology, 165-point scoring, SLDS 2 compliance, and dark mode support. Build modern Salesforce UIs.

Features

• Component Scaffolding: Generate complete LWC bundles (JS, HTML, CSS, meta.xml)
• PICKLES Architecture: Structured methodology for robust components
• 165-Point Scoring: Validation across 8 categories (SLDS 2 + Dark Mode)
• Wire Service Patterns: @wire decorators for Apex & GraphQL
• Jest Testing: Comprehensive unit test generation
• Spring '26 Features: TypeScript, lwc:on, Complex Expressions

Quick Start

1. Invoke the skill

Skill: experience-lwc-generate
Request: "Create a data table component for Account records"

2. Answer requirements questions

The skill will ask about:

• Component purpose
• Data source (LDS, Apex, GraphQL)
• Target (App Page, Record Page, Flow Screen)
• Accessibility requirements

3. Review generated component

The skill generates:

• JavaScript controller with decorators
• HTML template with SLDS styling
• CSS with styling hooks (dark mode ready)
• meta.xml configuration
• Jest test file

PICKLES Framework

P → Prototype    │ Validate ideas with wireframes & mock data
I → Integrate    │ Choose data source (LDS, Apex, GraphQL, API)
C → Composition  │ Structure component hierarchy & communication
K → Kinetics     │ Handle user interactions & event flow
L → Libraries    │ Leverage platform APIs & base components
E → Execution    │ Optimize performance & lifecycle hooks
S → Security     │ Enforce permissions, FLS, and data protection

Jest Configuration for SFDX Projects

If your project uses Jest, scope discovery to your Salesforce source so example assets in agent folders are not picked up during npm test.

const { jestConfig } = require('@salesforce/sfdx-lwc-jest/config');

module.exports = {
    ...jestConfig,
    roots: ['<rootDir>/force-app'],
    testPathIgnorePatterns: [
        '<rootDir>/node_modules/',
        '<rootDir>/.sfdx/',
        '<rootDir>/.agents/',
        '<rootDir>/.cursor/',
        '<rootDir>/.claude/',
        '<rootDir>/.pi/'
    ]
};

Example test assets in this skill now ship with a .example suffix. Copy them into your project and rename them before running Jest.

Requirements

• sf CLI v2
• Node.js 18+ (for Jest tests)
• Target Salesforce org
• API Version 66.0+ (Spring '26)
