Retry on condition

[Raphyyy]

Hi and thanks for your work

That would be great if a custom filter could be implemeted to perform the retry or not

A gentle way to replace something like this :

db.query("SELECT *...").then(() => {
	console.log("OK");
}).catch(error => {
	if (error == "ECONNREFUSED")
		retry(() => db.query("SELECT *..."), {timeout: 5000}).then(() => {
			console.log("OK");
		});
});

By something like this :

retry(() => db.query("SELECT *..."), {filter: (error) => { return (error == "ECONNREFUSED"); }, timeout: 5000})
	.then(() => {
		console.log("OK");
	})

Would the predicate option in the retryOptions object suit your needs?
