gulp-imagemin版本9圖片壓縮

爆发的驴子發表於2024-03-14

由於網上大多數的博文已經比較久,參考性不大

版本

  • gulp

    PS D:\XXX\github\hexo> gulp -v
    CLI version: 2.3.0
    Local version: 4.0.2
    
  • gulp-imagemin

    9.0.0
    
  • node

    PS D:\XXX\github\hexo> node -v
    v20.10.0
    PS D:\XXX\github\hexo> npm -v
    10.2.3
    PS D:\XXX\github\hexo>
    

gulpfile.js

import gulp from 'gulp';
import imagemin from 'gulp-imagemin';
let imgSrc = 'source/images/*.*'
let imgDist = 'source/images2'
// 壓縮圖片
export default (cb) => {
	return gulp.src([imgSrc])
	.pipe(imagemin())
    .pipe(gulp.dest(imgDist));
}

如果需要對某種型別進行配置

import gulp from 'gulp';
import imagemin, {optipng} from 'gulp-imagemin';
let imgSrc = 'source/images/*.*'
let imgDist = 'source/images2'
// 壓縮圖片
export default (cb) => {
	return gulp.src([imgSrc])
	.pipe(imagemin(optipng({optimizationLevel: 5}))) 
    .pipe(gulp.dest(imgDist));
}

如果希望已經壓縮過的圖片不再次壓縮,可以結合gulp-cache

import gulp from 'gulp';
import imagemin from 'gulp-imagemin';
import cache from 'gulp-cache';
let imgSrc = 'source/images3/*.*'
let imgDist = 'source/images2'
// 壓縮圖片
export default (cb) => {
	return gulp.src([imgSrc])
	.pipe(cache(imagemin()))
    .pipe(gulp.dest(imgDist));
}

輸出對比結果

// 第一次執行
PS D:\XXX\github\hexo> gulp
[16:55:41] Using gulpfile D:\XXX\github\hexo\gulpfile.js
[16:55:41] Starting 'default'...
gulp-imagemin: Minified 1 image (saved 116 kB - 8.7%)
[16:55:48] Finished 'default' after 7.23 s

// 再次執行命令
PS D:\XXX\github\hexo> gulp

新增一個圖片測試

PS D:\XXX\github\hexo> gulp
[16:58:15] Using gulpfile D:\XXX\github\hexo\gulpfile.js
[16:58:15] Starting 'default'...
gulp-imagemin: Minified 1 image (saved 208 kB - 40.4%)
[16:58:20] Finished 'default' after 5 s

這裡發現一個問題是,有些壓縮效果並不明顯

gulp-imagemin: Minified 1 image (saved 116 kB - 8.7%)
[16:55:48] Finished 'default' after 7.23 s

但如果你上傳到tinypng, 壓縮了差不多一半

遇到問題

    一、二、三同種問題,由於使用npm/yarn/pnpm install安裝的時候並沒有完全安裝成功

    解決方案:重新安裝

    // 如果曾經安裝過gulp-imagemin,有時需要刪除才可以
    rm -rf node_modules
    // !!!記住順序
    cnpm i optipng-bin -D
    cnpm i gulp-imagemin -D

    package.json中先刪除gulp-imagemin和optipng-bin

    {
      "devDependencies": {
        "gulp": "^4.0.2",
        "gulp-imagemin": "^9.0.0",
        "optipng-bin": "^9.0.0"
      }
    }
    

    再重新安裝

    rm -rf node_modules
    yarn install
    cnpm i optipng-bin -D
    cnpm i gulp-imagemin -D
