A sophisticated comment-posting app backed by a remote database using user images from Gravatar.

Front end is based on React. Backend is Node.js powered by Koa framework, with MongoDB with the Mongoose ORM/driver.

Clone repository:

git clone https://github.com/shtaif/kommentyr.git
cd kommentyr

Install dependencies:

npm install

Kommentyr knows the database to connect to based on the KMTR_DB_URI environment variable. Example to set this variable on Linux:

export KMTR_DB_URI=mongodb://localhost:27017/kommentyr

Optional: To override the default port of 4443, the environment variable KMTR_PORT can also be set:

export KMTR_PORT=4000

Start server via the start script:

npm start

When seeing the message Secure HTTP2 server running on <SOME_PORT> app is ready. If running on localhost with default port: https://localhost:4443 will serve the app.

• Live search (searches comments from the DB, ensuring reliable results)
• Pagination through Infinite scrolling (Add a lot of comments and see it in action!)
• Auto-resizing message field
• Modal with High-res image shown when clicking on a commenter's image
• In the user modal, clicking on the email address automatically filters for that user's own comments
• More...

• Ignore the warning about the HTTP2 module, it is emitted from Node.js itself and will probably disappear in the next Node.js releases.
• Why HTTPS? - I've chosen to use HTTP2 in this project because I think it is the future of the Web and can significantly benefit most projects. However, as for now, major browsers have chosen to support only the Secured HTTP2 (and will probably keep it like that), therefore the app is accessible only through https://.
• When accessing the frontend app in Chrome for the first time, a warning screen may display regarding invalid TLS certificate - It's normal and expected and caused by the certificate being self-signed. Just click on "ADVANCED" and then "Proceed to...".
