一个有点2的基于tinypng图片压缩服务的图片压缩工具;只支持png、JPEG格式图片
重要的事情说三遍 无需api key 无需api key 无需api key
https://github.com/weivea/tinypng2
稳定性依赖于当前网络环境访问 https://tinypng.com/ 的性能
勉强能用~ 不要声张~
ps: 基于网络,无网络时无法使用
require
node version >=12.4.0
Install
npm install -g @weivea/tinypng2
Usage
cd dirOfImage #进入指定目录
tinypng2 *.(png|jpeg)
use it as a module
npm install @weivea/tinypng2 --save
const tinyPng = require('@weivea/tinypng2')
const imgReadStream = fs.createReadStream(filePath)
tinyPng(imgReadStream).then((resultBuf)=>{
// resultBuf 压缩后得图片,Buffer
})
// 用完后记得调用; tinyPng.close(), tinyPng起了一个子进程来对 tinypng网站做爬虫
tinyPng.close()
ps: 只适用于单线程调用, tinyPng不能同时发起俩, 得在then回调之后再发起下一个,如下
run(imagePaths).then(()=>{
console.log('done')
tinyPng.close();
}).catch((er)=>{
console.error('run Error:', er)
tinyPng.close();
})
async function run(filePaths) {
const len = filePaths.length
for (let i=0; i<len; i++) {
const filePath = filePaths[i]
const imgReadStream = fs.createReadStream(filePath)
console.log('compress:', filePath)
const resultBuf = await tinyPng(imgReadStream)
// console.log(resultBuf)
const pathObj = path.parse(filePath);
pathObj.name = pathObj.name + '_tiny'
pathObj.base = ''
const newPath = path.format(pathObj)
// console.log(newPath)
const wStream = fs.createWriteStream(newPath)
const pass = new PassThrough()
pass.pipe(wStream)
pass.end(resultBuf)
console.log('compressed:', newPath)
}
}
