Promise-waterfall
Promise-waterfall extends promise utilities with sequential flow control like async.waterfall.
Since Promise.all(promiseArr)
|| Promise.spread(promiseArr)
execs promises simultaneously, each of the functions in the promiseArr cannot depend on another, and if you want promises execute in order or some of the promises need the resolved value of another, this library is for you.
Installation
npm install promise-waterfall
Usage
var waterfall = ;var { // return a promise } { // optionally use res1 // which is resolved from func1 // and return a promise } { // like func2 } promiseSequence = func1 func2 func3; // the promiseSequence will executes sequentially // just like func1().then(func2).then(func3) ;
See test cases in /tests
for full examples.
