@zcatalyst/push-notification

ZOHO CATALYST SDK for JavaScript PushNotification for Node.js and Browser.

Installing

To install this package, simply type add or install @zcatalyst/push-notification using your favorite package manager:

• npm install @zcatalyst/push-notification
• yarn add @zcatalyst/push-notification
• pnpm add @zcatalyst/push-notification

Getting Started

Import

The Catalyst SDK is modulized by Components. To send a request, you only need to import the PushNotification:

// ES5 example
const { PushNotification } = require('@zcatalyst/push-notification');

// ES6+ example
import { PushNotification } from '@zcatalyst/push-notification';

Usage

To send a request, you:

• Create a PushNotification Instance.
• Call the PushNotification operation with input parameters.

const notification = new PushNotification();

const webNotification = await notification.web();

Async/await

We recommend using await operator to wait for the promise returned by send operation as follows:

// async/await.
try {
	const data = await webNotification.sendNotification('Hey, I am notify you!', [
		'[email protected]'
	]);
	// process data.
} catch (error) {
	// error handling.
} finally {
	// finally.
}

Async-await is clean, concise, intuitive, easy to debug and has better error handling as compared to using Promise chains or callbacks.

Promises

You can also use Promise chaining to execute send operation.

webNotification.sendNotification('Hey, I am notify you!', ['[email protected]']).then(
	(data) => {
		// process data.
	},
	(error) => {
		// error handling.
	}
);

Promises can also be called using .catch() and .finally() as follows:

webNotification
	.sendNotification('Hey, I am notify you!', ['[email protected]'])
	.then((data) => {
		// process data.
	})
	.catch((error) => {
		// error handling.
	})
	.finally(() => {
		// finally.
	});

Callbacks

We do not recommend using callbacks because of callback hell, but they are supported by the send operation.

// callbacks.
webNotification.sendNotification('Hey, I am notify you!', ['[email protected]'], (err, data) => {
	// process err and data.
});

Troubleshooting

When the service returns an exception, the error will include the exception information, as well as response metadata (e.g. request id).

try {
	const data = await webNotification.sendNotification('Hey, I am notify you!', [
		'[email protected]'
	]);
	// process data.
} catch (error) {
	const message = error.message;
	const status = error.statusCode;
	console.log({ message, status });
}
