publicMediaUpload.md

Key interest features:

• function will send upload requests(PutObjectCommand) to S3 bucket, generated QR codes(.png),
  to do that the function requires permissions for that specific bucket, in order to do that at function configuration level
  as role property 👀 src/functions/upload-media/index.ts

export const publicMediaUpload: AWS["functions"]["publicMediaUpload"] = {
  handler: `${handlerPath(__dirname)}/handler.publicMediaUpload`,
  role: "arn:aws:iam::${aws:accountId}:role/DefaultPublicMediaUploader",

• function will implement middy middlewares, JsonBodyParser that's almost default,maybe a bit more interesting is SSM
  That will fetch AWS System Manager parameter store, we use this instead of .env files remember that your lambda will require permission for that too. HttpErrorHandler will take care of return http erros thrown at runtime.

• Endpoint will accept a base64 encoded binary file, for testing we pass Body=binary in postman, I think probable be better pass an url-form type of body, will do in upcoming iteration. I use that personally to upload images for public access like those shown as result in other .md files

• Probably even a better approach could be run a sam cmd directly to upload media. The endpoint was tested with several images/videos not bigger thatn 5MB
