Date and time picker in Ionic 2

Today I want to talk about date/time pickers in Ionic 2 framework because there are several ways to do it.

We will test it on two platforms available at the moment:

  • Android 5.1 (Huawei Lua-L21)
  • Chromium 56.0.2924.76 (LinuxMint 18 (64-bit))

How to handle MySQL Date and Time formats in Sequelize?

I’ve been playing with Sequelize for a while and one thing that I really didn't like about it is that how it deals with MySQL dates. It requires that fields of Date or Time types would be defined as default JavaScript date objects. This in my opinion causes some unnecessary problems as you need to do conversations between date strings in different formats...

For example we have two fields in MySQL:


And I need to create new entry and show it to the user

let now = new Date() // 2017-02-27T10:03:30.212Z

    CreateDate: now,
    CreateTime: now
}).then(function(created) {
    console.log(created.CreateDate) // 2017-02-27T10:03:30.212Z
    console.log(created.CreateTime) // 2017-02-27T10:03:30.212Z
  • The first thing you will notice is that all dates are in JS format, not like default MySQL dates 2017-02-27 12:03:30. Yes, on the next query you will get it, but for now sorry.
  • Second thing is that all those dates are in UTC. It's not bad, but in my case I needed it with exact time zone

To solve the first problem just add get methods to the fields. We will use Moment for date parsing.

CreateDate: {
    type: DataTypes.DATEONLY,
    get: function() {
        return moment.utc(this.getDataValue('CreateDate')).format('YYYY-MM-DD')
CreateTime: {
    type: DataTypes.TIME,
    get: function() {
        let time = this.getDataValue('CreateTime')

        if (moment(time, moment.ISO_8601, true).isValid()) {
            return moment(this.getDataValue('CreateTime')).format('HH:mm:ss')
        } else {
            return time

To solve the second problem you will need to set timezone for both Sequalize and Moment

const timezone = 'Europe/Vilnius'


let sequelize = new Sequelize(
        timezone: timezone

Making HTTP requests in Node.JS without any dependencies using Promise

Quite often programming on Node.JS I have to perform various types of HTTP requests. To do this, I simply use the library Request, but sometimes there are situations when you need to perform a query in a certain way and it becomes a problem. As a result, I decided to write a small module that solves this problem.

A Fix For Slow Sendmail [Linux, PHP]

Recently I have noticed that one of my PHP scripts that was sending emails via the mail() function were hanging for roughly one minute while waiting for Sendmail to work.

The problem was that Sendmail requires that the result of "hostname" be a fully qualified domain name to start cleanly.

To get the domain name type hostname command and then copy it to /etc/hosts like this: kiril-macbook.localdomain kiril-macbook localdev localhost
