This module let's you use the Circuit Breaker pattern and call a function multiple times. In addition you can specify a delay to be applied between attempts as well as extending the delay as attempts are made.
const BackOff = require('back-off');
const backoff = new BackOff({
times: 5, //number of times method should be called
delay: 50, //delay in milliseconds between calls
backoff: true // if the delay should be doubled between execution attempts
});
try {
const result = await backoff.execute(asyncTask);
} catch (error) {
//do something with the final error
}const BackOff = require('back-off');
const backoff = new BackOff({
times: 5, //number of times method should be called
delay: 50, //delay in milliseconds between calls
backoff: true // if the delay should be doubled between execution attempts
});
backoff.execute(() => {
//do something here that may fail
})
.then(()=> {
// do something else
})
.catch(() => {
//attempts failed
});The tests show the module in action.
