Unable to import csv to mongo through post method in node - node.js

Question

i wanted to create a fronted with a input type file for uploading data to my mongodb collection. I used the below code buts its giving me the following error
Error: ENOENT: no such file or directory, open 'C:\Users\User\cogazzimport\public\uploads\fcnewimport.csv'
My Codes
app.js
...
var storage = multer.diskStorage({
destination:(req,file,cb)=>{
cb(null,'./public/uploads');
},
filename:(req,file,cb)=>{
cb(null,file.originalname);
}
});
var uploads = multer({storage:storage});
//init app
var app = express();
//set the template engine
app.set('view engine','ejs');
//fetch data from the request
app.use(bodyParser.urlencoded({extended:false}));
//static folder
app.use(express.static(path.resolve(__dirname,'public')));
var temp ;
let url = "mongodb://localhost:27017/";
app.post('/',uploads.single('csv'),(req,res)=>{
csvtojson()
.fromFile(req.file.path)
.then(csvData => {
console.log(csvData);
mongodb.connect(
url,
{ useNewUrlParser: true, useUnifiedTopology: true },
(err, client) => {
if (err) throw err;
client
.db("coggaz")
.collection("idata")
.insertMany(csvData, (err, res) => {
if (err) throw err;
console.log(`Inserted: ${res.insertedCount} rows`);
client.close();
});
}
);
});
});
//assign port
var port = process.env.PORT || 3010;
app.listen(port,()=>console.log('server run at port '+port));
index.ejs
<form action="/" method="post" enctype="multipart/form-data">
<input type="file" name="csv"><br><br>
<div class="text-center"><button type="submit" class="btn btn-lg btn-primary">submit</button></div>
</form>
I tried various solutions but still getting the same error. Any solution with a correction code would be appreciated

Answer 1

use this code
var storage = multer.diskStorage({
destination:(req,file,cb)=>{
cb(null,'./public/uploads');
},
filename:(req,file,cb)=>{
cb(null,file.originalname);
}
});
var uploads = multer({storage:storage});
router.post('/import_data', uploads.single('file'), async (req, res) => {
try {
// importing csv file to database
const jsonArray = await csv().fromFile(req.file.path);
const roles = await Role.insertMany(jsonArray)
await roles.save()
res.send({msg:"csv data saved successfully"})
} catch (e) {
res.send(e)
}
use this and change Schema according to your databse name
