📚 General info

• Original instructions (User Stories) from FCC:

1. I can submit a form that includes a file upload.
2. The from file input field has the "name" attribute set to "upfile". We rely on this in testing.
3. When I submit something, I will receive the file name and size in bytes within the JSON response
4. To handle the file uploading you should use the multer npm package.

📶 Technologies

• Node v14 javaScript runtime built on Chrome's V8 JavaScript engine
• Express v5 Fast, unopinionated, minimalist web framework for Node.js
• multer v1 node.js middleware for handling multipart/form-data, mainly used for uploading files
• Cors v2 node.js package for providing Connect/Express middleware that can be used to enable CORS with various options.

💾 Setup

• Run node server.js for a dev server. Navigate to http://localhost:8080/.
• The app will not automatically reload if you change any of the source files.

💻 Code Examples

• extract from server.js to upload file and produce a json object with file details (or error message if it does not work)

app.post('/api/fileanalyse', upload.single('upfile'), (req, res, next) => {
	const fileSize = req.file && req.file.size;
	console.log(typeof fileSize); //should return 'number'
	res.json(
		typeof fileSize == 'undefined'
			? { error: 'sorry, but there is a file error' }
			: {
					name: req.file.originalname,
					type: req.file.mimetype,
					size: req.file.size + ' bytes',
			  }
	);
});

🆒 Features

• multer used to upload files - uploaded files stored in a folder named 'uploads'. If this folder does not exist then it is created.
