Node.js 使用Nimble实现串行流程控制

npm install nimble

var flow = require(‘nimble‘);

flow.series([
    function (callback) {
        setTimeout(function() {
            console.log(‘I excute first.‘);
            callback();
        }, 1000);
    },
    function (callback) {
        setTimeout(function() {
            console.log(‘I excute next.‘);
            callback();
        }, 500);
    },
    function (callback) {
        setTimeout(function() {
            console.log(‘I excute last.‘);
            callback();
        }, 100);
    }
]);
