Part 4 Profile Pic

1. App

   • ✔️ Main container component for the entire logged in experience It is the keeper of information about the logged in user.
   • ✔️ It fetches this info when it mounts and keeps user info in its state
   • ✔️ Renders a Logo, ProfilePic and Uploader
   • Passes functions to ProfilePic and Uploader for making changes to its state
   • ✔️ MUST be a class since it needs both state and lifecycle methods

2. ✔️ ProfilePic

   • ✔️ Its job is to display a profile pic (can use first and last name for the alt tag of the image)
   • ✔️ Is passed down props that tell it the first and last name of the urser and the url of the image.
   • ✔️ Is also passed down a prop that is a function that it must call when the image is clicked. When user clicks the pic, the uploader needs to become visible.
     • ✔️ props -- toggleUploader, name, url
   • ✔️ Can be a function or a class.

3. Uploader

   • ✔️ needs to be a class based component as it will have state
   • ✔️ you need to conditionally render Uploader. It starts off as hidden but when you click on the profilePic, you will make it visible. The conditional rendering of Uploader depends on the current state. Make it look like a modal.
   • ✔️ When visible, it needs to render a file input to make image upload possible
   • ✔️ handles the change event on the file input and uploads the selected file
   • ✔️ when the upload is done, you should know the url of the uploaded file and you must pass the url to a function in App for image upload, refer to what you did in IB. (formData, multer, s3, etc)
   • ✔️ The function we pass the url to will update the state in APP when there is a new image and will also close the modal afterwards.
   • ✔️ Maybe Uploader has a button or x for closing. This too must call a function that was passed down as a prop to make the Uploader disappear.
   • ✔️ You'll need to add a new column to your user's table for teh imageUrl - make it text
   • ✔️ Make sure you do an UPDATE for the image in the users table rather than an insert
