This module adds if else conditional capabilities to async module.
Ever came across code like this on your async.waterfall
flow?
var async = require('async');
async.waterfall([
async.constant({email: 'thiago@email.com', dogs: 2, money: 0, fun: 100 }),
updateUserEmailOrGetLegacy
sendEmail
], handler);
function updateUserEmailOrGetLegacy(user, cb) {
emailExists(user.email, function (err, value) {
if (err)
callback(err)
else {
if (user.email)
updateAccount(user, cb);
else
importFromLegacyByEmail(user, cb)
}
})
}
Using async-if-else
you can have a conditional waterfall without the need of a wrapper function.
And the code is so much more readable, don't you agree?
var async = require('async-if-else')(require('async'));
async.waterfall([
async.constant({email: 'thiago@email.com', dogs: 2, money: 0, fun: 100 }),
async.if(emailExists, updateAccount).else(importFromLegacyByEmail),
sendEmail
], handler);
You can also omit the else
and the function is only executed if the predicate is true.
var async = require('async-if-else')(require('async'));
async.waterfall([
async.constant({email: 'thiago@email.com', dogs: 2, money: 0, fun: 100 }),
async.if(emailExists, auditLogging),
publishToQueue
], handler);
if you don't wanna change the async object, you can always do something like that
var async = require('async');
var conditional = require('async-if-else')({});
async.waterfall([
async.constant({email: 'thiago@email.com', dogs: 2, money: 0, fun: 100 }),
conditional.if(emailExists, auditLogging),
publishToQueue
], handler);
