There are often times when we shared some message over slack which might contain some crucial information and can be misused. In such cases we need to make sure that the message is deleted or be careful of not sharing sensitive data, specially in case of organisational resources.

I have done this too 😜 which turned out to be the source of my project idea. This app will help you to share the message in form QR Code which will auto expire after 30 secs.

How I built it

I deployed my Node App on Digital Ocean Server. I created a Droplet where I managed all of my app resources. This was pretty straightforward and easy with help of documentations and articles available on web.

Installing ngnix and pointing DigitalOcean Nameservers From Common Domain Registrars became easy with setup guide.

Deployment and setup on Digital Ocean platform is very simple and quick. I really liked and enjoyed my journey while setting up my App on Digital Ocean. Kudos to the team πŸ˜‡

Additional Resources/Info

I will be sharing my whole journey and steps I followed from inception to go live stage of the app in my upcoming post. I will be detailing more about slack integrations and node app setup from initial to final phase.

All ears for feedbacks and suggestions!πŸ‘‚

Happy Coding!πŸ‘©πŸ»β€πŸ’»
