Single page applications make extensive use of xhr requests. However, as developers, we often don't check for scenarios that involve non-200 responses. Thus, we deploy our SPAs expecting the best, until we're notified that our beautiful app is breaking in production.
chaos-donkey is a reverse-proxy that returns non-200 responses for your xhr requests. It allows you to see how your application will perform when things go wrong.
npm i -g chaos-donkey
> chaos-donkey <configuration yaml>
example:
> chaos-donkey ./fixtures/mean-todomvc.ymlThe configuration yaml is a file that contains the following:
# This is your SPA
origin: mean-todomvc.herokuapp.com
xhr:
- path: /path/to/your/endpoint
# List the possible status codes you want your application to return
# If you don't specify this, it will return these status codes: 200, 403, 404, 500, 503
statusCodes:
- 200
- 500See other examples in the fixtures folder.
