Getting Started

Prerequisites

Setup your project with Capacitor. For details check here: https://capacitor.ionicframework.com/docs/

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

Installing

Install:

npm i --save @byrds/capacitor-contacts

Sync:

ionic capacitor sync

Run iOS using livereload:

ionic capacitor run ios --l

Usage / Examples

You have the following Methods available:

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

If you're considering to use this plugin you most likely want to retrive contatacts probably want to retrive a users contacts. Here's how I do that:

Import the Plugin in your TS file:

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

Next use it and console log the result:

CapContacts.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 now result now.

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.

Interfaces

export interface PermissionStatus {
  granted: boolean;
}

export interface Contact {
  contactId: string;
  displayName?: string;
  phoneNumbers: string[];
  emails: string[];
  organizationName?: string;
  organizationRole?: string;
  birthday?: string;
}

iOS Notes

For iOS you need to set use description in your info.plist file. 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 permision in you AndroidManifest.xml. Add the following permission 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(CapContacts.class);
    }});

Make sure to import it properly as well.

import ch.byrds.capacitorContacts.CapContacts;

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().
