I mostly do frontend at work, and I've always ignored building error states. Error states are a second class citizen in building UIs. One of the reasons is the developers building it don't get error states often from their APIs. What if we change that?
rest-in-chaos is a command line utility that spawns proxy server, a really shitty one at that. Every request made to the rest-in-chaos server is either proxied to the passed URL, or returns an error response. It's completely random. It's chaos.
Run the following command
go get -u github.com/nshntarora/rest-in-chaos
The binary will now be available in the bin directory in your GOPATH
rest-in-chaos <<YOUR URL>>
The server will be running on the port 24267
rest-in-chaos http://localhost:3000
Any request to localhost:24267 will be proxied to localhost:3000, with the exception of some requests chosen at random.
