Gulp plugin for extracting CSS module to JSON file using PostCSS

This plugin based on gulp-postcss-modules, but you can pass custom generateScopedName callback for postcss-modules plugin.

Usage

Basic

gulp.task('css-modules',
    () => gulp.src('lib/**/*.css')
      .pipe(cssModules())
      .pipe(gulp.dest(options.defaultDir));
});

Custom generateScopedName according to [https://github.com/webpack/loader-utils#interpolatename]

gulp.task('css-modules',
    () => gulp.src('lib/**/*.css')
      .pipe(cssModules(
            '[name]__[local]___[hash:base64:5]',
          ))
      .pipe(gulp.dest(options.defaultDir));
});

Also you can pass array of postcss plugin as second parameter, it will be passed directly to postcss module

gulp.task('css-modules',
    () => gulp.src('lib/**/*.css')
      .pipe(cssModules(
            '[name]__[local]___[hash:base64:5]',
            [
              // init postcss plugins
            ]
          ))
      .pipe(gulp.dest(options.defaultDir));
});
