Challenge

Creating the image upload page

In this module we will add a form to the image upload page. We will also setup our server, and add a wildcard route to serve the image upload page. ### Solution To view the solution, run git diff origin/master..module-1-solution in the Terminal, and press Enter to see the next lines of the difference.

You may also browse the files of the solution by stashing your changes with git stash and running git checkout module-1-solution to switch branches.
Challenge

Storing the image on disk

You may also browse the files of the solution by stashing your changes with git stash and running git checkout module-2-solution to switch branches.
Challenge

Serving the photo-viewer and creating the workers

In this module we will add a route to serve the photo-viewer page. We will also create our two workers that will process the images. ### Solution To view the solution, run git diff origin/master..module-3-solution in the Terminal, and press Enter to see the next lines of the difference.

You may also browse the files of the solution by stashing your changes with git stash and running git checkout module-3-solution to switch branches.
Challenge

Creating the parent thread

In this module we will create the parent thread as well as instantiate the worker threads. We will write event listeners to handle communication between threads. Finally, we will wire up the parent thread to the upload route, and add the processed images to the photo-viewer page. ### Solution To view the solution, run git diff origin/master..module-4-solution in the Terminal, and press Enter to see the next lines of the difference.

You may also browse the files of the solution by stashing your changes with git stash and running git checkout module-4-solution to switch branches.
