gulp-metalsmith

gulp-metalsmith is a gulp plugin that incorporates Metalsmith builds into gulp pipelines. It aims to be as lightweight as possible. It ships with Metalsmith's replacement that has compatible API (can reuse Metalsmith plugins) and is able to recive JavaScript object containing page definitions. After build, it streams out vinyl files. The main difference between bundled Metalsmith and normal Metalsmith is that it does not perform any disc read/write operations, leaving it out to gulp.

gulp-metalsmith can be feed with specially formatted JSON. It allows building static pages using content providers, like prismic.io or Contentful.

Installation

$ npm install --save-dev gulp-metalsmith

Use it with gulp

The simplest build task (just copies all files from src/ to build/):

gulp.task('metalsmith', ['clean'], function() {
    return gulp.src('src/**').
        pipe(metalsmith()).
        pipe(gulp.dest('build'));
});

All options:

s.pipe(metalsmith({
    // set Metalsmith's root directory, for example for locating templates, defaults to CWD
    root: __dirname, 
    // read frontmatter, defaults to true
    frontmatter: true,
    // Metalsmith plugins to use
    use: [ permalinks(), layouts({ engine: 'swig' }) ]
}));

Feed it with JSON

Given the file src/pages.json:

{
  "index.html": {
    "title": "Homepage",
    "layout": "basic.swig",
    "contents": "<p>In euismod eleifend nunc ac pretium...</p>"
  },
  "contact.html": {
    "title": "Contact",
    "layout": "basic.swig",
    "contents": "<p>Lorem ipsum dolor sit amet...</p>"
  }
}

You can do this:

gulp.task('metalsmith-json', ['clean'], function() {
    return gulp.src('src/pages.json').
        pipe(metalsmith({ use: [ layouts({ engine: 'swig' }) ])).
        pipe(gulp.dest('build'));
});

Multiple JSON files (*.json) are also accepted.

Examples, tests

Examples are stored in example/. Tests can be run using tape (you probably just need to type faucet in the project's root directory).
