error on azure table storage upload file using nodejs expreesjs - node.js

Question

I m trying to upload images/videos file on to azure blob storage using
nodejs. But on uploading through postman Im getting error, even though
I can see the file object in console. Below is the code for it.
const addProductImage = async (req: any, res: Response) => {
try {
console.log(req.files.file);
if (!req.files) {
res.status(400).send({ status: Status.ERROR, error: "No file uploaded" });
}
let file = req.files.file;
const sharedKeyCred = new StorageSharedKeyCredential(accName, acckey)
const blobServClient1 = new BlobServiceClient(`https://${accName}.blob.core.windows.net`, sharedKeyCred)
const containerClient1 = blobServClient1.getContainerClient(containerName)
const blockBlobClient = containerClient1.getBlockBlobClient(file.name);
await blockBlobClient.upload(file, file.size);
res.status(200).send({ status: Status.SUCCESS, });
}
catch (error: any) {
res.status(500).send({ status: Status.ERROR, error });
}
}
the above codes console is -
{

On uploading a file in postman under form-data with "file" as key and
hitting post, it gives error

Answer 1

Here If you use multer package to read the file in the form-data.
Then you can set Multer to read the form-data where the file is using the .single('<Name of the Feild>') . Here the name of the field must be the same one in which you are adding the file. here I am using the postman with field name as test
Now you can set up multer like this
var multer = require('multer');
var upload = multer();
app.use(upload.single('test'));
Complete Api code :
var express = require('express');
var multer = require('multer');
const { BlobServiceClient } = require("#azure/storage-blob");
var app = express();
var upload = multer();
app.use(express.json());
app.use(express.urlencoded({ extended: false }));
app.use(upload.single('test'));
const blobServiceClient = BlobServiceClient.fromConnectionString('<Connection String From Portal>');
const containerClient = blobServiceClient.getContainerClient('< Name of the Container>');
app.get('/', async (req,res)=>{
const blockBlobClient = containerClient.getBlockBlobClient(req.file.originalname.toString());
await blockBlobClient.upload(file.toString() , file.size);
res.send(req.file.size.toString());
});
app.listen(3000);
Postman output:
Portal:
