promise.walk

Call promises in sequential order and return all the resolved contents to the callback function. (Rejected promise will not block the further promise execution.)

how to use?

Install dependence:

npm install promise-walk --save

Sample code:

const pw = require('promise-walk');
 
//define promises
var apple = function () { 
    return new Promise(function (resolve, reject) {
        setTimeout(function () { console.log('apple'); resolve('eat apple'); }, 3000);
    });
};
 
var orange = function () {
    return new Promise(function (resolve, reject) {
        setTimeout(function () { console.log('orange'); resolve('eat orange'); }, 1000);
    });
};
 
var banana = function () {
    return new Promise(function (resolve, reject) {
        setTimeout(function () { console.log('banana'); resolve('eat banana'); }, 2000);
    });
};
 
//call promises in sequential order and get back the results
pw.walk([apple, banana, orange], function (results) {
    console.log('All promise results are stored here:');
    console.log(results);
});

Result:

apple
banana
orange
All promise results are stored here:
[ 'eat apple', 'eat banana', 'eat orange' ]
