Mobile Push notifications and realtime chat Using parse or pubnub in ionic app

Both Parse and PubNub are popular platforms for implementing mobile push notifications and real-time chat functionality in Ionic apps. They provide easy-to-use APIs and SDKs that simplify the process of adding these features to your app.

1. Parse: Parse is a Backend-as-a-Service (BaaS) platform that provides various services, including push notifications and data storage. It's now an open-source project called "Parse Server," and you can host it on your own infrastructure or use a third-party Parse hosting service.

   To integrate Parse with your Ionic app, you'll need to install the Parse SDK and set up the Parse Server. Here's an outline of the steps:

   • Set up the Parse Server on your preferred hosting platform or use a third-party Parse hosting service.
   • Install the Parse JavaScript SDK in your Ionic app using npm.
   • Initialize the Parse SDK with your Parse Server URL and Application ID.
   • Use the Parse API to handle user authentication, data storage, and push notifications.

   For real-time chat functionality, you can implement a simple chat feature using Parse's data storage and push notifications. However, keep in mind that Parse is not primarily designed for real-time communication, and more advanced chat features might require additional customization.

2. PubNub: PubNub is a real-time messaging platform that specializes in delivering real-time data streams and has extensive support for real-time chat applications.

   To use PubNub with your Ionic app, you'll need to install the PubNub JavaScript SDK and set up your PubNub account. Here's a brief outline of the steps:

   • Sign up for a PubNub account and get your API keys.
   • Install the PubNub JavaScript SDK in your Ionic app using npm.
   • Initialize the PubNub SDK with your API keys.
   • Use the PubNub API to implement real-time chat functionality, including sending and receiving messages between users.

   PubNub provides features like presence detection, message history, and channel management, making it a robust choice for real-time chat applications.

Ultimately, the choice between Parse and PubNub depends on your specific requirements and preferences. If you need a more comprehensive backend solution with data storage, user authentication, and push notifications, Parse might be a suitable choice. On the other hand, if you require advanced real-time messaging capabilities and a dedicated platform for chat functionality, PubNub might be a better fit.

Before making a decision, carefully review the features, documentation, pricing, and scalability of both platforms to ensure they align with your app's needs.
