File Upload demo

Env Vars Required

S3_BUCKET_NAME='<some name>'
REGION='<some region>'

How it works

• Multer <> allows local file upload.
• AWS control comes with @aws-sdk (an SDK is a 'Software Development Kit' - like templates for best practice usage)
• We use the S3 client (client-s3) part to write our files to S3 buckets.

If you look in upload.js you can see us create a system which, depending on if a S3_BUCKET_NAME is provided. We create and create multer middleware. We then use that in our routes, e.g. /routes/artists.js

const upload = require("./../upload"); // Where we create the middleware

router.post("/", upload.array("photos", 30), addArtist);
//               ^^ Where we use it
