# @gar/promise-retry
|
|
|
|
This is a fork of [promise-retry](https://npm.im/promise-retry). See the [CHANGELOG.md](./CHANGELOG.md) for more info.
|
|
It also inlines and updates the original [retry](https://github.com/tim-kos/node-retry) package that was being promisified.
|
|
|
|
Retries a function that returns a promise, leveraging the power of the [retry](https://github.com/tim-kos/node-retry) module to the promises world.
|
|
|
|
There's already some modules that are able to retry functions that return promises but they were rather difficult to use or do not offer an easy way to do conditional retries.
|
|
|
|
|
|
## Installation
|
|
|
|
`$ npm install promise-retry`
|
|
|
|
|
|
## Usage
|
|
|
|
### retry(fn(retry, number, operation), [options])
|
|
|
|
Calls `fn` until the returned promise ends up fulfilled or rejected with an error different than a `retry` error.
|
|
The `options` argument is an object which maps to the original [retry](https://github.com/tim-kos/node-retry) module options:
|
|
|
|
- `retries`: The maximum amount of times to retry the operation. Default is `10`.
|
|
- `factor`: The exponential factor to use. Default is `2`.
|
|
- `minTimeout`: The number of milliseconds before starting the first retry. Default is `1000`.
|
|
- `maxTimeout`: The maximum number of milliseconds between two retries. Default is `Infinity`.
|
|
- `randomize`: Randomizes the timeouts by multiplying with a factor between `1` to `2`. Default is `false`.
|
|
- `forever`: Whether to retry forver, default is false.
|
|
- `unref`: Whether to [unref](https://nodejs.org/api/timers.html#timers_unref) the underlying `setTimeout`s.
|
|
- `maxRetryTime`: Maximum number of milliseconds that the retried operation is allowed to run.
|
|
|
|
`options` can also be a Number, which is effectively the same as pasing `{ retries: Number }`
|
|
|
|
|
|
The `fn` function will be called with the following parameters:
|
|
- A `retry` function as its first argument that should be called with an error whenever you want to retry `fn`. The `retry` function will always throw an error.
|
|
- The current retry number being attempted
|
|
- The retry operation object itself from which will allow you to call things like `operation.reset()`
|
|
|
|
If there are retries left, it will throw a special `retry` error that will be handled internally to call `fn` again.
|
|
If there are no retries left, it will throw the actual error passed to it.
|
|
|
|
## Example
|
|
```js
|
|
const { retry } = require('@gar/promise-retry');
|
|
|
|
// Simple example
|
|
retry(function (retry, number) {
|
|
console.log('attempt number', number);
|
|
|
|
return doSomething()
|
|
.catch(retry);
|
|
})
|
|
.then(function (value) {
|
|
// ..
|
|
}, function (err) {
|
|
// ..
|
|
});
|
|
|
|
// Conditional example
|
|
retry(function (retry, number) {
|
|
console.log('attempt number', number);
|
|
|
|
return doSomething()
|
|
.catch(function (err) {
|
|
if (err.code === 'ETIMEDOUT') {
|
|
retry(err);
|
|
}
|
|
|
|
throw err;
|
|
});
|
|
})
|
|
.then(function (value) {
|
|
// ..
|
|
}, function (err) {
|
|
// ..
|
|
});
|
|
```
