Launch server after all async task ready

---

Install

m install ready-callback

Usage

Note: ready-callback is using class, so you should use node>=2

koa = require('koa');
ready = require('ready-callback')();
app = koa();
y.mixin(app);

egister a service
done = app.readyCallback('service');
iceLaunch(done);

allback will be fired after all service launched
ready(function() {
p.listen();

Error Handle

If task is called with error, error event will be emit, ready will never be called.

egister a service that will emit error
done = app.readyCallback('service');
iceLaunch(function(err) {
ne(err);


isten error event
on('error', function(err) {
 catch error

Weak Dependency

If you set a task weak dependency, task will be done without emit error.

done = app.readyCallback('service', {isWeakDep: true});
iceLaunch(function(err) {
ne(err);


ill be ready
ready(function() {
p.listen();


on('error', function(err) {
 never be called

You can also set for all ready-callback

ready = require('ready-callback')({isWeakDep: true});

Ready Status

You can get status every callback end.

on('ready_stat', function(data) {
nsole.log(data.id); // id of the ended task
nsole.log(data.remain); // tasks waiting to be ended

Timeout

You can set timeout when a task run a long time.

ready = require('ready-callback')({timeout: 1000});
y.mixin(app);
on('ready_timeout', function(id) {
 this will be called after 1s that `service` task don't complete


done = app.readyCallback('service');
iceLaunch(function() {
 run a long time
ne();

You can also set timeout for every task

y.mixin(app);
on('ready_timeout', function(id) {
 this will be called after 1s that `service` task don't complete


done = app.readyCallback('service1', {timeout: 1000});
iceLaunch(done);
