Advanced tools
This module helps to you to manage retries of function execution
// 1. Import module
const retrier = require('retry-if-fails');
// 2. Define your function
const flipCoin = () => {
return Math.random() > 0.5 ? 'Heads' : 'Tails';
}
// 3. Define your test function
const resultChecker = coinFlip => {
console.log(coinFlip);
return coinFlip === 'Heads'
}
// 4. Run the Retrier
const retries = 3;
retrier(flipCoin, resultChecker, retries)
.then( result => console.log(`Finally! ${result}`))
.catch( lastResult => console.log(`Error: Last result was: ${lastResult}`));
The retrier function returns a Promise, and it will execute until it hits the desired result or it' will return the last failed result.
You can also set a wait time between tries with the optional last parameter. This can be useful when your functions consume a remote resource.
const retries = 3;
const wait = 200; // 200 milliseconds
retrier(flipCoin, resultChecker, retries, wait);
const retrier = require('retry-if-fails');
const fetch = require('node-fetch');
const fetchResource = () => {
return fetch('http://domain.com/resource/12345', { timeout: 3000 })
.catch(err => console.log(err));
}
const resultChecker = response => {
return response && response.status == 200;
}
const retries = 3;
const wait = 1000;
retrier(fetchResource, resultChecker, retries, wait)
.then( res => res.json())
.then( object => console.log(object))
.catch( lastResponse => console.log(`It fails. Last result was: ${lastResponse}`));
const foo = async () =>{
try{
const result = await retrier(process, checkCorrect, retries, wait);
console.log(`It's correct! ${result}`);
}
catch(lastResult){
console.log(console.log(`It fails. Last result was: ${lastResult}`))
}
};
