Fetcher

Configurable throttled Fetch API

Usage

Instantiate a Fetcher({ interval: number, max: number }) instance

• interval: interval between each fetch, in milliseconds
• max: number of fetches to run in parallel

const fetcher = new Fetcher({ interval: 1000, max: 1 });

Use the fetch method as you would normally do with the fetch API.

// These five calls will call sequentially since `max` is set to 1
["/", "/status/500", "/ip", "/", "/"].forEach(path => {
    fetcher.fetch(`https://httpbin.org/${path}`).then(() => console.log(path, 'loaded'));
});
