I just released a small library to put some troubles in my Node.JS Express applications.
https://github.com/drouian-m/express-chaos-middleware
How to use it ?
Add the dependency to the project.
npm add express-chaos-middleware
Then load the module in the express application :
const { chaos } = require('express-chaos-middleware');
app.use(chaos());
After that the chaos module will be triggered on every route call and goes randomly:
- slow down the application
- return http errors
- throw exceptions
Probabilities of having issues and the randomly triggered effects can be configured with the input param object ((see documentation))[https://github.com/drouian-m/express-chaos-middleware#usage]
Effects
Here are some results of library effects observable with a Grafana dashboard.
