I'm trying to send my form using React frontend to NodeJS backend and I'm not getting any data in formData() object, here is my code for React:
import { useState, useEffect } from 'react'
import Axios from 'axios'
import Notification from '../../../components/Notification'
const DashboardWorkAdd = ({ subTitle = 'works' }) => {
//Form States
const [workName, setWorkName] = useState('')
const [workGithub, setWorkGithub] = useState('')
const [workOnlineLink, setWorkOnlineLink] = useState('')
const [workDate, setWorkDate] = useState('')
const [workDesc, setWorkDesc] = useState('')
const [workAdded, setworkAdded] = useState('')
const [workAddedMsg, setworkAddedMsg] = useState('')
const [workImgFile, setWorkImgFile] = useState('')
const [preview, setPreview] = useState()
const formMsg = document.querySelector('.notification__msg')
const updateWorkImg = (e) => {
const file = e.target.files[0]
if (file) {
const fileType = file.type.split('/')[0]
const fileSizeToMB = file.size / 1000000
const MAX_FILE_SIZE = 1 //mb
if (formMsg) {
formMsg.classList.remove('hidden')
if (fileType !== 'image') {
formMsg.textContent = 'you can add only image file'
} else if (fileSizeToMB > MAX_FILE_SIZE) {
formMsg.textContent = `you can't add more than ${MAX_FILE_SIZE} MB`
return
} else {
formMsg.classList.add('hidden')
formMsg.textContent = ''
setWorkImgFile(file)
}
}
}
}
useEffect(() => {
// if there's an image
if (workImgFile) {
const reader = new FileReader()
reader.onloadend = () => setPreview(reader.result)
reader.readAsDataURL(workImgFile)
} else {
setPreview(null)
}
}, [workImgFile])
const handleAddWork = async (e) => {
e.preventDefault()
//using FormData to send constructed data
const formData = new FormData()
formData.append('workImg', workImgFile)
formData.append('workName', workName)
formData.append('workGithub', workGithub)
formData.append('workOnlineLink', workOnlineLink)
formData.append('workDate', workDate)
formData.append('workDesc', workDesc)
console.log(formData)
if (
(workName === '' || workGithub === '' || workOnlineLink === '' || workDate === '',
workDesc === '')
) {
formMsg.textContent = 'please add all data'
} else {
try {
const response = await Axios.post(
`${
process.env.NODE_ENV === 'development'
? process.env.REACT_APP_API_LOCAL_URL
: process.env.REACT_APP_API_URL
}/workAdd`,
{ workImgFile, workName, workGithub, workOnlineLink, workDate, workDesc }
)
const { workAdded, message } = response.data
setworkAdded(workAdded)
setworkAddedMsg(message)
} catch (err) {
console.error(err)
}
}
}
return (

Here is my code for NodeJS:
const WorksModel = require('../models/WorkModel')
const { v4: uuidv4 } = require('uuid')
module.exports = async (req, res) => {
const { workName, workGithub, workOnlineLink, workDate, workDesc } = req.body
const { workImg } = req.files
const workImgName = uuidv4() + workImg.name
const workImgMovePath = `${__dirname}/../../client/public/uploads/${workImgName}`
const workImgDisplayPath = `/uploads/${workImgName}`
const works = new WorksModel({
workImgDisplayPath,
workName,
workGithub,
workOnlineLink,
workDate,
workDesc
})
try {
await works.save()
workImg.mv(workImgMovePath, (err) => {
if (err) {
res.send({ message: `sorry, something wrong with the server: ${error}` })
return res.status(500).send(err)
}
})
res.send({
message: 'added succesfully',
workAdded: 1
})
} catch (error) {
res.send({
message: `something went wrong ${error}`,
workAdded: 0
})
}
}
and my WorkModel file is :
const mongoose = require('mongoose')
const WorkSchema = new mongoose.Schema({
workImgDisplayPath: {
type: String,
required: true
},
workName: {
type: String,
required: true
},
workGithub: {
type: String,
required: true
},
workOnlineLink: {
type: String,
required: true
},
workDate: {
type: Date,
required: true,
default: new Date().toLocaleDateString('ar-EG', {
weekday: 'long',
year: 'numeric',
month: 'short',
day: 'numeric'
})
},
workDesc: {
type: String,
required: true
}
})
const WorkModel = mongoose.model('mhmdhidrPortfolio', WorkSchema)
module.exports = WorkModel
the issue I'm having when I get the data in the backend is the req.files are undefined, I googled a lot and I don't know the issue exactly.
Thanks for your help.
I solved my problem, I just had to add:
const fileUpload = require('express-fileupload')
app.use(express.json())
app.use(express.urlencoded({ extended: true }))
app.use(fileUpload())
inside my index.js (server) file
