Example

metalsmith.json config example:

{
  "plugins": {
    "metalsmith-favicons": {
      src: '**/logo.png',
      dest: 'favicons/',
      icons: {
        android: true, 
        appleIcon: true, 
        favicons: true
      }
    }
  }
}

Build script example:

var metalsmith = require('metalsmith');
var markdown = require('metalsmith-markdown');
var favicons = require('metalsmith-favicons');


metalsmith(__dirname)
  .source('src')
  .destination('pub')
  .use(favicons({
    src: '**/logo.png',
    dest: 'favicons/',
    icons: {
      android: true, 
      appleIcon: true, 
      favicons: true
    }
  }))
  .use(markdown({
    gfm: true,
    tables: true
  }))
  .build(function (err) {
    if (err) {
      throw err;
    }
  });

metalsmith-favicons will add a favicons property to metalsmith.metadata() with one property html, which is an array of the meta and link tags for use in your templates. Loop over this html array to add the needed tags in your html head so your new favicons show up on your site.

An example in Jade:

html
  head
    if favicons && favicons.html
      each item in favicons.html
        != item
