Logz.io FED Interview Exercise

The main idea of this exercise is to create a website comments component.
A mockup is ready as a reference to the style (in the file mockup.png inside the repo), and a basic server API is at your service, so you should have all you need to start.

The minimum requirements are as follows :

Design the comments component like the mockup.
Add the 'submit' functionality - A user will enter an email and message, and the comment will be added to the list below. The list should be ordered by date.
A gravatar will be added to the 'comment' object created (get the matching gravatar from: https://en.gravatar.com/)
When a user enters text in the filter input, it will filter the comments accordingly.
Add server side validation to the submitted comment.
No need to use any kind of db or persistency.
Do not use any UI/CSS framework (i.e.: bootstrap)
Do not send the node_modules directory back, and do not commit it. It is not needed (and you shouldn't have any changes there anyway).

Additional Notes :

Use an MVC framework of choice - AngularJS, Angular, React etc.
Make sure all code is clean and testable, as you would commit it to production.
You can use other known js libraries as you see fit.
You should work on this exercise ~2-3 hours, not more. I assume you won't complete everything in this time frame, and that's ok - The idea is to see some code you worked on, and not to have a perfect working project that's production ready. (Perfect is the enemy of good)
You can use ES6 synatx

For Bonus Points :

Add unit tests.
Save the newly added comments on the server, so they will be saved when refreshing the page.
Design a responsive layout.

How to use the code :

Clone the repo.
Run npm install (to download all relevant dependencies)
Run npm start (to start the server)
Open your browser and go to 'http://localhost:3000'
