library1.0.2jsnpmunverified

A Gulp plugin to optimize Polymer 2 components by minifying HTML, JavaScript, and CSS. It uses Babel for JS transpilation (with presets like 'babili' or 'es2015'), cssclean for CSS minification, and integrates uglify-js for JS minification. Current stable version is 1.0.2. Release cadence is low; last update was around 2017. Useful for legacy Polymer 2 builds but no longer actively maintained.

This shows how to set up a Gulp task that uses gulp-polymin2 to optimize Polymer 2 HTML components.

var gulp = require('gulp'); var polymin = require('gulp-polymin2'); gulp.task('compress', function() { return gulp.src('src/*.html') .pipe(polymin({ babelPressets: 'es2015', cssOptions: {}, jsOptions: null })) .pipe(gulp.dest('dist')); });

Known issues
deprecatedPackage is deprecated; no longer maintained. Use modern tools like polymer-build or webpack.
fix
Migrate to polymer-cli or @polymer/build.
affects: *
gotchaOption name 'babelPressets' is misspelled (should be 'babelPresets'). Using 'babelPressets' will be ignored.
fix
Use correct option: { babelPresets: 'es2015' }.
affects: <=1.0.2
gotchaIf jsOptions is null, uglify-js is not applied. Some expect minification by default.
fix
Explicitly set jsOptions to {} to enable uglify with defaults.
affects: *
breakingRequires Babel 6; incompatible with Babel 7+.
fix
Use babel-core@^6.0.0 or switch to a modern tool.
affects: >=1.0.0 <2.0.0
