Implementation Reference

• index.js:988-1027 (handler)

  Main handler function that runs Next.js specific audits by evaluating JavaScript in the browser context via CDP to check for __NEXT_DATA__, Image component usage, Link components, and Head usage.

  async runNextJSAudit() {
    await this.ensureChromium();
    
    const result = await this.sendCDPCommand('Runtime.evaluate', {
      expression: `
        const results = [];
        const nextData = document.querySelector('#__NEXT_DATA__');
        if (!nextData) {
          results.push('This does not appear to be a Next.js application');
          JSON.stringify(results);
        } else {
          const nextImages = document.querySelectorAll('img[data-nimg]');
          const regularImages = document.querySelectorAll('img:not([data-nimg])');
          
          if (regularImages.length > 0 && nextImages.length === 0) {
            results.push(\`Consider using Next.js Image component for \${regularImages.length} images\`);
          }
          
          const internalLinks = Array.from(document.querySelectorAll('a[href^="/"]')).length;
          if (internalLinks > 0) {
            results.push(\`Found \${internalLinks} internal links - ensure Next.js Link component is used\`);
          }
          
          const headTags = document.querySelectorAll('meta, title, link[rel="stylesheet"]');
          if (headTags.length < 3) {
            results.push('Consider using Next.js Head component for better SEO');
          }
          
          JSON.stringify(results.length > 0 ? results : ['Next.js specific checks passed']);
        }
      `,
      returnByValue: true
    });
    
    const nextjsResults = JSON.parse(result.result?.value || '[]');
    
    return {
      content: [{ type: 'text', text: `Next.js Audit Results:\\n${nextjsResults.join('\\n')}` }],
    };
  }
