is-network-error
Check if a value is a Fetch network error
This can be useful when you want to do something specific when a network error happens without catching other Fetch-related errors.
Unfortunately, Fetch network errors are not standardized and differ among implementations. This package handles the differences.
For instance, p-retry uses this package to retry on network errors.
Install
npm install is-network-error
Usage
import isNetworkError from 'is-network-error';
async function getUnicorns() {
try {

return await response.json();
} catch (error) {
if (isNetworkError(error)) {
return localStorage.getItem('…');
}
throw error;
}
}
console.log(await getUnicorns());
API
