imagemin-concurrent-skip-preserve

Minify images seamlessly

Install

$ npm install imagemin-concurrent-skip-preserve

Usage

const imagemin = require('imagemin-concurrent-skip-preserve');
const imageminJpegtran = require('imagemin-jpegtran');
const imageminPngquant = require('imagemin-pngquant');

(async () => {
	const files = await imagemin(['images/*.{jpg,png}'], 'build/images', {
		plugins: [
			imageminJpegtran(),
			imageminPngquant({quality: '65-80'})
		]
	});

	console.log(files);
	//=> [{data: <Buffer 89 50 4e …>, path: 'build/images/foo.jpg'}, …]
})();

// keep folder structure as input
const imagemin = require('imagemin-concurrent-skip-preserve');

imagemin(['images/**/*.{jpg,png}'], {
  
});
// for example
// images/a.jpg => images/a.jpg
// images/foo/a.jpg => images/foo/a.jpg
// images/foo/bar/a.jpg => images/foo/bar/a.jpg

// keep folder structure as input use imagemin-webp
const imagemin = require('imagemin-concurrent-skip-preserve');
const imageminWebp = require("imagemin-webp");

imagemin(['images/**/*.{jpg,png}'], {
  use: [
    imageminWebp({})
  ]
});
// for example
// images/a.jpg => images/a.webp
// images/foo/a.jpg => images/foo/a.webp
// images/foo/bar/a.jpg => images/foo/bar/a.webp

// customize folder structure as input use imagemin-webp
const imagemin = require('imagemin-concurrent-skip-preserve');
const imageminWebp = require("imagemin-webp");

imagemin(['images/**/*.{jpg,png}'], {
  use: [
    imageminWebp({})
  ],
  replaceOutputDir: output => {
    return output.replace(/images\//, '.webp/')
  }
});
// for example
// images/a.jpg => .webp/a.webp
// images/foo/a.jpg => .webp/foo/a.webp
// images/foo/bar/a.jpg => .webp/foo/bar/a.webp

// Limit concurrency of minimizers
const imagemin = require('imagemin-concurrent-skip-preserve');
const imageminWebp = require("imagemin-webp");

imagemin(['images/**/*.{jpg,png}'], {
  use: [
    imageminWebp({})
  ],
  concurrency: 16, // default limit: number of CPUs
  replaceOutputDir: output => {
    return output.replace(/images\//, '.webp/')
  }
});

// Skip files by extension
const imagemin = require('imagemin-concurrent-skip-preserve');
const imageminWebp = require("imagemin-webp");

imagemin(['images/**/*.{jpg,png}'], {
  use: [
    imageminWebp({})
  ],
  skipExtensions: ['webp', 'jpeg'],
  replaceOutputDir: output => {
    return output.replace(/images\//, '.webp/')
  }
});
