Install

npm install @s-blog/engine

The correct native binary for your platform is installed automatically.

Supported Platforms

| OS | Arch | Package | |---------|-------|----------------------------------| | Windows | x64 | @s-blog/engine-win32-x64-msvc | | macOS | ARM64 | @s-blog/engine-darwin-arm64 | | Linux | x64 | @s-blog/engine-linux-x64-gnu |

macOS Intel users: the ARM64 binary runs seamlessly via Rosetta 2.

CLI

The package registers an s-blog binary. In a user project, this is invoked via npm scripts:

{
  "scripts": {
    "dev": "s-blog serve",
    "build": "s-blog build"
  }
}

s-blog build

Runs the full production build pipeline:

1. Copies the pre-built App Shell from @s-blog/core
2. Generates posts manifest and copies Markdown files
3. Processes album photos (WebP thumbnails + EXIF extraction)
4. Generates SEO pages, sitemap.xml, rss.xml, robots.txt
5. Copies static assets from public/

s-blog build [--output <dir>]

Options:
  --output <dir>  Output directory (default: dist)

s-blog serve

Starts a development server with live content rebuilding:

s-blog serve [--port <number>]

Options:
  --port <number>  Port to listen on (default: 3000)

Node.js API

For programmatic use (e.g., custom build scripts):

const {
  generatePostsData,
  generatePostsManifestOnly,
  generateAlbumsData,
  generateSeoPages,
  generateSitemap,
  generateRss,
  generateRobots,
  buildCommand,
  serveCommand,
} = require('@s-blog/engine')

generatePostsData(postsDir, outputDir, configJson) → string

Scans postsDir for Markdown files, parses frontmatter, generates manifest.json, and copies .md files to outputDir/posts/. Returns the manifest as a JSON string.

generatePostsManifestOnly(postsDir, outputDir, configJson) → string

Same as generatePostsData but skips copying Markdown files. Used in dev mode where files are served directly from source.

generateAlbumsData(albumsDir, outputDir, albumConfigJson, siteConfigJson) → string

Generates album index and per-album detail JSON files, including WebP thumbnail generation and EXIF extraction. Returns the albums-index JSON string.

generateSeoPages(manifestJson, templatePath, outputDir, configJson) → number

Generates an SEO-optimized HTML page for each post (Open Graph, Twitter Card, JSON-LD). Returns the number of pages generated.

generateSitemap(manifestJson, outputPath, configJson) → void

Generates sitemap.xml conforming to the Sitemaps protocol.

generateRss(manifestJson, outputPath, configJson) → void

Generates rss.xml conforming to RSS 2.0.

generateRobots(outputPath, configJson) → void

Generates robots.txt with sitemap reference.

buildCommand(optionsJson) → string

Executes the full production build pipeline. Accepts { "outputDir": "dist" }. Returns a JSON string with build results:

{
  "durationMs": 1234,
  "shellFilesCount": 15,
  "postsCount": 3,
  "albumsCount": 2,
  "seoPagesCount": 3,
  "staticFilesCount": 5
}

serveCommand(optionsJson) → void

Starts the dev server. Accepts { "port": 3000 }. Blocks until terminated.

Config Format

All configJson parameters accept a JSON string matching config.json:

{
  "title": "My Blog",
  "description": "A personal blog",
  "logo": "/logo.png",
  "favicon": "/favicon.ico",
  "siteUrl": "https://example.com",
  "author": "Author",
  "language": "en",
  "timezone": "Asia/Tokyo",
  "basePath": "/",
  "github": "https://github.com/username/repo"
