How to Integrate Contact Plugin of Ionic

Thanks to Ionic's documentation, many developers struggle in integrating it's native API. Today I am gonna walk you through how to integrate and use Contact API of Ionic. I have used Ionic (version 3) with Angular ( Version 4) to implement this feature .

1. Installation of Contact Plugin

 Use following commands to install Contact plugin and corresponding node packages.These commands will update your package.json and config.xml.
$ ionic cordova plugin add cordova-plugin-contacts
$ npm install --save @ionic-native/contacts

2. Adding Plugin In App Module

    a. Import Contact plugin in your app.module.ts file
import { Contacts } from '@ionic-native/contacts';

    b. Add Contacts entry in list of provides in your app.module.ts file
providers:[
    ...
    Contacts
    ...
]

3. Use Contact plugin into Component

    a. Import Contact plugin in your xyz.component.ts file
import { Contacts } from '@ionic-native/contacts';

    b. Add Contacts reference in constructor
constructor(
    ...
    private contacts: Contacts,
    ...
) {}

    c. Write a function to use native Contact picker
pickContact() {
    this.contacts.pickContact().then((contact) => {
        this.name = contact.displayName;
    });
}

4. Template

<button ion-button (click)="pickContact();">
     {{transaction.accountability.title}}
</button>

By following steps above you will able to integrate Ionic Contact API into your application. It will add a button on your page on clicking on which Contact Picker will be launched. After selected a contact from the Contact Picker, It will display the contact name onto the button.

Stack implementation using VanillaJS

Stack is a very popular data structure. It is present as library classes/interfaces in many object oriented language like Java, C#. In JavaScript there is no stack data structure by default but we can create one. I have written following code which can be used to utilize Stack features in JavaScript development. import UVModal from './UVModal'; var Stack = function(){   var items = [];   /**    * @description Pushes an item onto the top of this stack.    * @param {any} item - the item to be pushed onto this stack.    */   function push(item) {     items.push(item);   }   /**    * @description Removes the object at the top of this stack and returns that object    * @return {any} - The object at the top of this stack    */   function pop() {     return items.pop();...

In order to make website/application we have to set some best practices standards and every teammate should follow that. I have written down few of the best practices which I recommend to be followed in any JavaScript development. Use === Instead of == Eval = Evil Don't use short-hand                      Bad Recommended if(condition) x = false; if(condition){ x = false; } Place scripts at the bottom of your page. The fastest way to build a HTML list. var arr = ['item 1', 'item 2', 'item 3', ...]; var list = '<ul><li>'+arr.join('</li><li>')+'</li></ul>'; Reduce global variables and methods. Add comme...
