Implementation

Phase 1: Setup & Design System (Week 1-2)

Goals:

Project setup và tooling
Design system implementation
Component library development

Technical Setup:

// next.config.ts
import type { NextConfig } from 'next';
 
const nextConfig: NextConfig = {
  i18n: {
    locales: ['vi', 'en'],
    defaultLocale: 'vi',
    localeDetection: true,
  },
  images: {
    domains: ['images.ctfassets.net'], // Contentful CDN
    formats: ['image/webp', 'image/avif'],
  },
  // Enable Incremental Static Regeneration
  experimental: {
    isrMemoryCacheSize: 0,
  },
};
 
export default nextConfig;

Component Library:

Created reusable components:

<Button> - Multiple variants (primary, secondary, outline)
<Card> - Content cards với consistent styling
<Section> - Layout wrapper với responsive spacing
<Heading> - Typography components với SEO
<ContactForm> - Multi-step form với validation

Design System:

// tailwind.config.js
module.exports = {
  theme: {
    extend: {
      colors: {
        primary: {
          50: '#eff6ff',
          // ... full color scale
          900: '#1e3a8a',
        },
        // Brand colors
        brand: {
          blue: '#0066CC',
          navy: '#003366',
          gray: '#F5F5F5',
        },
      },
      fontFamily: {
        sans: ['Inter', 'sans-serif'],
        heading: ['Montserrat', 'sans-serif'],
      },
    },
  },
};

Phase 2: CMS Integration & Content Migration (Week 3-4)

Contentful Content Modeling:

// types/contentful.ts
interface PageContent {
  sys: {
    id: string;
    contentType: {
      sys: { id: 'page' };
    };
  };
  fields: {
    title: string;
    slug: string;
    seoTitle: string;
    seoDescription: string;
    content: Document; // Rich text content
    locale: 'vi' | 'en';
  };
}
 
interface ServiceContent {
  // Service-specific fields
  title: string;
  description: string;
  icon: Asset;
  features: string[];
  pricing?: PricingInfo;
}

GraphQL Data Fetching:

// lib/contentful.ts
import { createClient } from 'contentful';
 
const client = createClient({
  space: process.env.CONTENTFUL_SPACE_ID!,
  accessToken: process.env.CONTENTFUL_ACCESS_TOKEN!,
});
 
export async function getPageBySlug(slug: string, locale: string) {
  const entries = await client.getEntries({
    content_type: 'page',
    'fields.slug': slug,
    locale,
    limit: 1,
  });
 
  return entries.items[0];
}
 
export async function getAllPages(locale: string) {
  const entries = await client.getEntries({
    content_type: 'page',
    locale,
  });
 
  return entries.items;
}

Static Site Generation:

// app/[locale]/[slug]/page.tsx
export async function generateStaticParams() {
  const pages = await getAllPages('vi');
  
  return pages.map((page) => ({
    locale: page.fields.locale,
    slug: page.fields.slug,
  }));
}
 
export default async function Page({ 
  params 
}: { 
  params: { locale: string; slug: string } 
}) {
  const page = await getPageBySlug(params.slug, params.locale);
  
  return (
    <article>
      <h1>{page.fields.title}</h1>
      <RichText content={page.fields.content} />
    </article>
  );
}

Phase 3: SEO & Performance Optimization (Week 5-6)

SEO Implementation:

// app/[locale]/[slug]/page.tsx
import type { Metadata } from 'next';
 
export async function generateMetadata({ 
  params 
}: { 
  params: { locale: string; slug: string } 
}): Promise<Metadata> {
  const page = await getPageBySlug(params.slug, params.locale);
  
  return {
    title: page.fields.seoTitle,
    description: page.fields.seoDescription,
    alternates: {
      canonical: `https://consultpro.vn/${params.locale}/${params.slug}`,
      languages: {
        'vi': `/vi/${params.slug}`,
        'en': `/en/${params.slug}`,
      },
    },
    openGraph: {
      title: page.fields.seoTitle,
      description: page.fields.seoDescription,
      url: `https://consultpro.vn/${params.locale}/${params.slug}`,
      siteName: 'ConsultPro Vietnam',
      locale: params.locale === 'vi' ? 'vi_VN' : 'en_US',
      type: 'website',
    },
  };
}

Performance Optimizations:

Image Optimization:
- Convert all images to WebP/AVIF
- Implement lazy loading
- Use Next.js Image component
- Compress images to <100KB
Code Splitting:
- Dynamic imports cho heavy components
- Route-based splitting automatic with App Router
Caching Strategy:
- Static pages cached at CDN edge
- ISR revalidation every 60 seconds
- Client-side caching với SWR
Bundle Optimization:
- Tree shaking unused code
- Minification và compression
- CSS purging với Tailwind

Phase 4: Testing & Launch (Week 7-8)

Testing Strategy:

// __tests__/pages/home.test.tsx
import { render, screen } from '@testing-library/react';
import HomePage from '@/app/[locale]/page';
 
describe('HomePage', () => {
  it('renders hero section', () => {
    render(<HomePage />);
    expect(screen.getByRole('heading', { level: 1 })).toBeInTheDocument();
  });
 
  it('displays CTAs', () => {
    render(<HomePage />);
    expect(screen.getByText('Contact Us')).toBeInTheDocument();
  });
});

Performance Testing:

Lighthouse scores: 98/100 average
Core Web Vitals:
- LCP: 1.2s
- FID: <100ms
- CLS: 0.05
