Multer Muti Upload Image With Express - node.js

Question

I use React and Express for create Mutiupload Image
multer.js
const multer = require('multer');
const storage = multer.diskStorage({
destination: function (req, file, cb) {
cb(null, './public/')
},
filename: function (req, file, cb) {
cb(null, new Date().toISOString() + '-' + file.originalname)
}
})
const fileFilter = (req, file, cb) => {
if (file.mimetype === 'image/jpeg' || file.mimetype === 'image/png') {
cb(null, true)
} else {
//reject file
cb({message: 'Unsupported file format'}, false)
}
}
const upload = multer({
storage: storage,
limits: { fileSize: 1024 * 1024 },
fileFilter: fileFilter
})
module.exports = upload;
post.controller.js
async onInsert(req, res) {
try {
let result = await Service.insert(req.body)
res.success(result, 201);
} catch (error) {
res.error(error.message, error.status)
}
},
post.service.js
insert(data) {
return new Promise(async(resolve, reject) => {
try {
const obj = new Post(data)
let inserted = await obj.save()
resolve(inserted)
} catch (error) {
reject(methods.error(error.message, 400))
}
});
},
I try to implements Multer on this controller but it can't upload anyway . so how to implements mutiple upload image with this code thank
I use mongoose by the way

Answer 1

const fileStorage = multer.diskStorage({
destination: (req, file, cb) => {
cb(null, 'images');
},
filename: (req, file, cb) => {
cb(null, new Date().toISOString().replace(/:/g, '-') + file.originalname);
}
});
const fileFilter = (req, file, cb) => {
if (
file.mimetype === 'image/png' ||
file.mimetype === 'image/jpg' ||
file.mimetype === 'image/jpeg'
) {
cb(null, true);
} else {
cb(null, false);
}
};
const csrfProtection = csrf();
app.use(bodyParser.urlencoded({ extended: false }));
app.use(
multer({ storage: fileStorage, fileFilter: fileFilter }).fields(
[
{
name: 'image1',
maxCount: 1
},
{
name: 'image',
maxCount: 1
},
{
name: 'passbook',
maxCount: 1
},
{
name:'certificate',
maxCount:1
}
]
)
);
in controller
const image=req.files.image1;
const passbook=req.files.passbook;
const certificate=req.files.passbook;
if (!image || !passbook || !certificate) {
console.log("img err");
return res.redirect('admin/');
}
const imageUrl = image[0].path;
const passbookUrl= passbook[0].path;
const certificateUrl= certificate[0].path;
this works for me but i have only used Nodejs
