i want to read the csv data uploaded to backened.



for this i am sending the data via post from front end..



frontend code:



fileEvent(e) {
this.filedata = e.target.files;
if (this.filedata.length > 0) {
const file: File = this.filedata[0];
console.log(file);
const formData: FormData = new FormData();
formData.append('files', file, file.name);
this.http.post('myUrl', {file: formData}, this.options)
.subscribe((res) => {
});
}
}


screenshot of my file:
enter image description here



now on backened i have written route on api.js that directs me
to the controller i have created.



my api.js code:



router.post('/product/csvdata', function (req, res) {
productimport.importcsvProduct(req, res);
});


and finally on my controller i am consoling my data:



    var product = {
importcsvProduct: function (req,res) {
console.log(req.body.file);
}
};

module.exports = product;


but i am getting empty {} in console..??



can anyone check whats wrong with this..??

  • you may need body-parser as a middleware and configure it to accept form data

You need to use a file handling middleware in this case, such as multer.



const express = require('express')
const multer = require('multer')
const upload = multer({ dest: 'uploads/' })

const app = express()

app.post('/profile', upload.single('csvdata'), function (req, res, next) {
// req.file is the `csvdata` file
// req.body will hold the text fields, if there were any
})
