pug-filters@4.0.0

Breaking Changes

• The minify option on filters now requires you to install the relevant jstransformer (#3084)

  Currently we support:

  • jstransformer-uglify-js for JavaScript
  • jstransformer-clean-css for CSS

• Drop support for node 6 and 8 (#3243)

New Features

• Support filters that expect a Buffer instead of a string (#3213)

  e.g.

  // options.js
  exports.filters = {
    png: {
      // instead of a function, specify an object with a "renderBuffer" property
      // whose value is a function that takes a Buffer instead of a string
      renderBuffer: function(buffer, options) {
        var data = Buffer.from(buffer).toString('base64');
        return '`img src="data:image/png;base64, ' + data + '"/>';
      }
    }
  };

  You can then use the filter like:

  // foo.pug
  include:png my-small-image.png
