Show HN: Launching my side project – Build and send invoices with ease

cannonvoice.com

I've been building this product for a while. Even though there aren't any loading indicators, I think it's still good enough to get out there!

I've used this project as a test bed for learning new technologies. And what did I learn? That using Docker and Kubernetes effectively is harder than I thought it would be.

Some maybe interesting things about the technology used:

  * It's almost 100% TypeScript
  * What's not TypeScript is plpgsql
  * Postgres
  * Nodejs
  * Docker
  * Deployed to a Kubernetes cluster
  * React on the frontend
  * React also renders HTML on the backend (for the PDF generation and emails too)

> TypeScript

So you used an SPA framework like angular/ember or is it pure JS?

> * Docker * Deployed to a Kubernetes cluster

That's interesting, do you get enough volume (or foresee it in future) to justify Kubernetes? What would have been the difference in cost/performance if you had hosted on plain old LAMP system?

Absolutely not. I chose kubernetes because I was interested in learning more about it

Just React and Mobx

I'm a personal friend of John's, so I'll just +1 this project. It's a pretty solid and simple invoicing tool. Quick form to produce the invoice from a template, sends the email with a pdf version attached, and then gives you a tool to track sent-invoices states. He's been doing contract work a while so he's hit all the features you'd want from this.

If you're doing contract work, I'd suggest giving it a shot. Invoices are always a PITA so this is handy. Congrats on the release John
