Create a Robust Standard Publication Pipeline

Robust Standard Publication Pipeline

Overview

This specification outlines the design and implementation of a standardized publication pipeline for the lossless-monorepo project. The pipeline will transform content from source directories (content/lost-in-public/prompts and content/specs) into web-ready Astro components for the public website, ensuring consistent formatting, metadata, and organization.

Objectives

  1. Automate the conversion of Markdown content to Astro components
  2. Implement content-type specific validation and publication criteria
  3. Maintain relationships between source files and published files
  4. Provide comprehensive reporting on publication status and issues
  5. Ensure content security through appropriate validation checks

Technical Specifications

1. Publication Readiness Criteria

Different content types have different criteria for determining publication readiness:
Content TypePublication-Ready Status Values
Prompts"Implemented", "Published"
Specifications"Approved", "Implemented"

2. Directory Structure

The publication pipeline will maintain a clear separation between source and published content:
text 
/content/
  /lost-in-public/
    /prompts/
      /category1/
        file1.md
        file2.md
  /specs/
    file1.md
    file2.md

/site/public/
  /prompts/
    file1.astro
    file2.astro
  /specs/
    file1.astro
    file2.astro

3. Astro Component Generation

The pipeline will generate Astro components with appropriate layouts based on content type:
typescript 
// For prompts
const layoutComponent = 'PromptLayout';

// For specifications
const layoutComponent = 'SpecificationLayout';

const astroContent = `---
// Generated from ${filePath}
// Publication date: ${new Date().toISOString()}
layout: '@layouts/${layoutComponent}.astro'
title: ${JSON.stringify(frontmatter.title)}
lede: ${JSON.stringify(frontmatter.lede || '')}
date: ${JSON.stringify(frontmatter.date_modified || frontmatter.date_created)}
tags: ${JSON.stringify(frontmatter.tags || [])}
site_uuid: ${JSON.stringify(frontmatter.site_uuid)}
---

${content}
`;

4. Required Metadata

All published content must include the following metadata:
  • title: The main title of the content
  • lede: A brief description or summary
  • date: The last modification date or creation date
  • tags: Categorization tags for filtering and discovery
  • site_uuid: Unique identifier for the resource on the website

5. Publication Process

The publication process will be implemented as a method in the FileSystemObserver class:
typescript 
async processFileForPublication(filePath: string, frontmatter: any, content: string) {
  // Only process prompts and specifications
  if (!filePath.includes('lost-in-public/prompts') && !filePath.includes('specs')) {
    return;
  }
  
  // Check if the resource is ready for publication
  const isPrompt = filePath.includes('lost-in-public/prompts');
  const isSpec = filePath.includes('specs');
  
  // Different publication criteria based on content type
  let readyForPublication = false;
  
  if (isPrompt) {
    // Prompts are ready when status is 'Implemented' or 'Published'
    readyForPublication = ['Implemented', 'Published'].includes(frontmatter.status);
  } else if (isSpec) {
    // Specs are ready when status is 'Approved' or 'Implemented'
    readyForPublication = ['Approved', 'Implemented'].includes(frontmatter.status);
  }
  
  if (!readyForPublication) {
    console.log(`${filePath} is not ready for publication. Status: ${frontmatter.status}`);
    return;
  }
  
  // Determine publication directory based on content type
  let publicationDir;
  if (isPrompt) {
    publicationDir = path.join(this.contentRoot, 'public', 'prompts');
  } else if (isSpec) {
    publicationDir = path.join(this.contentRoot, 'public', 'specs');
  }
  
  // Create directory if it doesn't exist
  await fs.promises.mkdir(publicationDir, { recursive: true });
  
  // Generate filename from title or original filename
  const filename = frontmatter.title 
    ? frontmatter.title.toLowerCase().replace(/\s+/g, '-') + '.astro'
    : path.basename(filePath, '.md') + '.astro';
  
  const publicationPath = path.join(publicationDir, filename);
  
  // Generate Astro component with appropriate layout
  const layoutComponent = isPrompt ? 'PromptLayout' : 'SpecificationLayout';
  
  const astroContent = `---
// Generated from ${filePath}
// Publication date: ${new Date().toISOString()}
layout: '@layouts/${layoutComponent}.astro'
title: ${JSON.stringify(frontmatter.title)}
lede: ${JSON.stringify(frontmatter.lede || '')}
date: ${JSON.stringify(frontmatter.date_modified || frontmatter.date_created)}
tags: ${JSON.stringify(frontmatter.tags || [])}
site_uuid: ${JSON.stringify(frontmatter.site_uuid)}
---

${content}
`;
  
  // Write the Astro file
  await fs.promises.writeFile(publicationPath, astroContent, 'utf8');
  
  // Log the publication
  this.reportingService.logPublication(filePath, publicationPath);
}

6. Reporting Service Enhancements

The ReportingService will need to be extended to track and report on publication activities:
typescript 
// Add to ReportingService class
private publicationLog: Array<{source: string, target: string, timestamp: string}> = [];

/**
 * Log a publication event
 * @param sourcePath The source file path
 * @param targetPath The target publication path
 */
logPublication(sourcePath: string, targetPath: string): void {
  const timestamp = new Date().toISOString();
  this.publicationLog.push({ 
    source: sourcePath, 
    target: targetPath,
    timestamp
  });
  console.log(`✅ Published ${sourcePath} to ${targetPath}`);
}

/**
 * Format the publication log for the report
 * @returns A formatted string
 */
private formatPublicationLog(): string {
  if (this.publicationLog.length === 0) {
    return 'No publications were performed.';
  }
  
  let result = '';
  
  // Group by source file
  const publicationsBySource = new Map<string, Array<{target: string, timestamp: string}>>();
  
  for (const pub of this.publicationLog) {
    if (!publicationsBySource.has(pub.source)) {
      publicationsBySource.set(pub.source, []);
    }
    publicationsBySource.get(pub.source)!.push({
      target: pub.target,
      timestamp: pub.timestamp
    });
  }
  
  for (const [source, publications] of publicationsBySource.entries()) {
    const basename = path.basename(source);
    
    result += `#### [[${basename}]]\n`;
    for (const pub of publications) {
      const targetBasename = path.basename(pub.target);
      const date = new Date(pub.timestamp).toLocaleString();
      result += `- Published to \`${targetBasename}\` at ${date}\n`;
    }
    result += '\n';
  }
  
  return result;
}

Current Implmentations use Destructuring instead of Validation:

your pattern:
Props Structure: The component expects an array of objects via the contentThreads prop.
astro 
const { contentThreads = [] } = Astro.props;
Passthrough Data: As you pointed out, and as the comments confirm, there's no explicit TypeScript interface or type definition for the items within contentThreads at this layout level. The component relies on the upstream data source to provide objects with the necessary fields.
No type enforcement is used; this is required by .windsurfrules.
Prop Spreading: The objects from contentThreads are spread directly as props to child components (PostCardFeature.astro and PostCard.astro). For example: astro
astro 
<PostCardFeature {...contentThreads[0]} />
// ...
<PostCard {...item} />
This means that PostCardFeature.astro and PostCard.astro are responsible for defining and accessing the specific properties they need from the spread object. They must also handle cases where expected properties might be missing, if applicable. This "passthrough" and prop-spreading approach shifts the responsibility of knowing the data shape to the components that ultimately consume the individual fields.
Destructure Directly: We should destructure all expected fields (e.g., title, lede, category, banner_image, portrait_image, authors, date_created, date_last_updated, tags, imageAlt) directly from Astro.props (or Astro.props.entry.data if the prop is named entry and contains the full collection entry object).
Type Coercion/Handling: For fields like tags or dates, we need to implement similar defensive logic to what PostCard.astro does: Ensure tags becomes a clean array. Format dates carefully, handling potential undefined or incorrect string formats.
Conditional Rendering and Fallbacks: Use conditional rendering (e.g., &&) for optional elements and provide fallbacks (e.g., ||) where appropriate (like using a default placeholder image if banner_image and portrait_image are missing).
No Explicit Interface in Props: We will not define a TypeScript interface Props for the component's props if the data is coming directly from a collection entry using .passthrough(). The "type safety" comes from careful, defensive access within the component's script.

Best Practices

  1. Content Security:
    • Never publish content with sensitive information
    • Implement validation checks for publication-ready content
    • Require explicit approval for publication
  2. Error Handling:
    • Implement robust error handling for all publication steps
    • Log detailed error information for troubleshooting
    • Provide clear error messages for content authors
  3. Performance Considerations:
    • Optimize file operations for large content repositories
    • Implement batching for bulk publications
    • Consider asynchronous processing for large files
  4. Code Organization:
    • Maintain separation of concerns between validation and publication
    • Share utility functions across the publication pipeline
    • Follow the single source of truth principle

Constraints and Limitations

  1. Non-Destructive Operations:
    • Publication should never modify source files
    • All transformations should be applied during the publication process
  2. Backward Compatibility:
    • Support existing content formats and structures
    • Provide migration paths for legacy content
  3. Resource Utilization:
    • Monitor memory usage during large publication operations
    • Implement throttling for high-volume publication requests

Future Considerations

  1. Multi-Format Output:
    • Support additional output formats beyond Astro (e.g., PDF, ePub)
    • Implement format-specific transformations
  2. Internationalization:
    • Support for multiple languages and locales
    • Implement translation workflows
  3. Version Control Integration:
    • Track publication history in version control
    • Implement rollback capabilities for published content

Conclusion

This robust standard publication pipeline will provide a consistent, reliable mechanism for transforming internal content into web-ready resources. By implementing this specification, we will ensure that all published content meets quality standards, contains required metadata, and is properly organized for discovery and consumption.
