limited-map
Async map function with limited concurrency for JavaScript. This is a replacement for Promise.all(items.map(asyncCallback))
. For example, this is useful if you have an API that you don't want to overload with your request flood.
Example
const limitedMap = require("limited-map");
async function fetchDocs() {
const docs = await limitedMap(urls, url => getJSON(url), 30);
return docs;
}
API
limitedMap<T, U>(
items: Array<T>,
callback: (item: T, index: number, array: Array<T>) => Promise<U>,
concurrency: number
): Promise<Array<U>>
