promise-recurse

Recursive promise chains. Useful e.g. for paginated APIs that include a promise or URL for next page in each response.

Install

npm install --save promise-recurse

Use

promiseRecurse(startPromise: Promise, makeNextPromise: Function): Promise

• startPromise A promise to resolve first.
• makeNextPromise A function that, given the resolved value of previous promise, returns next promise to resolve. Return a falsy value to end.

var promiseRecurse = require('promise-recurse').promiseRecurse
 
promiseRecurse(start, (result) => {
  return result.nextPage // supposing `nextPage` is a promise
})
.then((results) => {
  // `results` is an array of each result
})
