declare const pEachSeries: {

/**
|
|
Iterate over promises serially.
|
|
|
|
@param input - Iterated over serially in the `iterator` function.
|
|
@param iterator - Return value is ignored unless it's `Promise`, then it's awaited before continuing with the next iteration.
|
|
@returns A `Promise` that fulfills when all promises in `input` and ones returned from `iterator` are fulfilled, or rejects if any of the promises reject. The fulfillment value is the original `input`.

|
|
@example
|
|
```
|
|
import pEachSeries = require('p-each-series');
|
|
|
|
const keywords = [
|
|
getTopKeyword(), //=> Promise
|
|
'rainbow',
|
|
'pony'
|
|
];
|
|
|
|
const iterator = async element => saveToDiskPromise(element);
|
|
|
|
(async () => {
|
|
console.log(await pEachSeries(keywords, iterator));
|
|
//=> ['unicorn', 'rainbow', 'pony']
|
|
})();
|
