Node.js '[object File]' BLOB

Question

I'm trying to obtain a BLOB from a request. The request object is constructed using FormData in Angular.

const buffer = fs.readFileSync(fileFromRequest);

The code above returns an error:

Error: ENOENT: no such file or directory, open '[object File]'

I can't find any resource to read/parse [object File].

Hope you guys can help me on this. Many thanks!

I want to get the uploaded file's extension & size from Angular. But when I receive the request object in my node app, it's of type [object File] — James Rudolf

You can use Multer npmjs.com/package/multer for uploading the file to the nodejs app. — iAmADeveloper

When upload a file using angular to node.js you cant use this

const buffer = fs.readFileSync(fileFromRequest);

The fs module only use to read to local file from the server. To handle upload data you can use multer
