I have recently built a Stack Overflow clone with Dgraph and React. I was delightfully surprised by the pleasant developer experience and the performance of my application. In this post, I would like to tell the story of how I built Graphoverflow and share the best practices I learned for using Dgraph to build a modern web application.

One of the common use case in Go is to start a few goroutines to do some work. These goroutines block listening in on a channel, waiting for more work to arrive. At some point, you want to signal these goroutines to stop accepting more work and exit, so you can cleanly shut down the program.
