如何在Node.js中将JPG图像转换为WEBP格式? [英] How to convert JPG image to WEBP format in Node.js?
问题描述
我正在尝试使用react.Js上传图像,然后使用multer中间件将该图像保存在node.Js中.效果很好,但是现在我想使用webp-converter将该图像转换为WEBP格式,反之亦然.
I m trying to upload an image using react.Js and save that image in node.Js using multer middleware. This is working perfectly but now I want to convert that image to WEBP format using webp-converter which is a small vice- versa.
但是我遇到了这个错误:
But I m getting this error :
Error: Command failed: E:\Zegal\node_modules\webp-converte

如何在使用multer和WEBP的节点中解决此问题?有没有其他转换解决方案?
How can I solve this problem in node using multer and WEBP ? Is there any other solution for conversion ?
const multer = require('multer');
const webp = require('webp-converter');
const path = require('path');
const storage = multer.diskStorage({
destination: './public/images',
filename(req, file, cb) {
cb(null, `${file.fieldname}-${Date.now()}${path.extname(file.originalname)}`)
}
});
const upload = multer({
storage,
fileFilter: function (req, file, cb) {
checkFileType(file, cb)
}
}).single("image");
checkFileType = (file, cb) => {
console.log("check file", file);
const requireMimetype = "image/jpeg";
const checkMimeType = file.mimetype == requireMimetype ? true : false;
console.log("checkMimeType", checkMimeType);
if (checkMimeType) {
webp.cwebp(file.originalname, "output.webp", "-q 80", function (status) {
console.log(status);
});
return cb(null, true)
} else {
cb("Error:Only jpg images are allowed.")
}
}
module.exports = upload;
推荐答案
我使用了一个非常出色的图像处理库,名为 sharp
,该库提供的功能之一是转换图像.到webp图片
I had used a really awesome image processing library named sharp
, and one of the features that that library offer is to convert an image into a webp image
import sharp from 'sharp';
const imageProcessing = sharp();
imageProcessing
.webp()
.pipe(someWritableStream);
