Prerequisites

Setup your project with Capacitor. For details check here: https://capacitorjs.com

cd my-app
npm install --save @capacitor/core @capacitor/cli

Initalize Capacitor

npx cap init

Add the platforms you want to use.

npx cap add android
npx cap add ios
npx cap add electron

Installation

Install:

npm i --save @diadal/contact

Sync:

npx cap sync

iOS

For iOS you need to set a usage description in your info.plist file. (Privacy Setting) Open xCode search for your info.plist file and press the tiny "+". Add the following entry:

Privacy - Contacts Usage Description

Give it a value like:

"We need access to your contacts in order to do something."

Android Notes

For Android you have to add the permisions in your AndroidManifest.xml. Add the following permissions before the closing of the "manifest" tag.

<uses-permission android:name="android.permission.READ_CONTACTS" />
<uses-permission android:name="android.permission.WRITE_CONTACTS"/>

Next import the capContacts class to your MainActivity

// Initializes the Bridge
    this.init(savedInstanceState, new ArrayList<Class<? extends Plugin>>() {{
      // Additional plugins you've installed go here
      // Ex: add(TotallyAwesomePlugin.class);
      add(Contacts.class);
    }});

Make sure to import it properly as well.

import ng.diadal.capacitor.contacts.Contacts;

NOTE: On Android you have to ask for permission first, before you can fetch the contacts. Use the getPermissions() method before you try to fetch contacts using getContacts().

Usage / Examples

You have the following Methods available:

export interface ContactsPlugin {
  getPermissions(): Promise<PermissionStatus>;
  getContacts(): Promise<{contacts: Contact[]}>;
}

If you're considering to use this plugin you most likely want to retrive contacts a users contacts:

Import the Plugin in your TS file:

import { Plugins } from "@capacitor/core";
const  { Contacts } = Plugins;

Next use it and console log the result:

Contacts.getContacts().then(result => {
    console.log(result);
    for (const contact of result.contacts) {
        console.log(contact);
    }
});

That's it. Do Whatever you want with the retrived contacts.

If you're trying to build something like "contacts matching" based on phone numbers i recommend using google libphonenumber: https://www.npmjs.com/package/google-libphonenumber

In order to match them properly you need to format them before you can match or store them properly.
