@zcatalyst/connector

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

Installing

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

• npm install @zcatalyst/connector
• yarn add @zcatalyst/connector
• pnpm add @zcatalyst/connector

Getting Started

Import

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

// ES5 example
const { Connector } = require('@zcatalyst/connector');

// ES6+ example
import { Connector } from '@zcatalyst/connector';

Usage

To send a request, you:

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

const connector = new Connector({
 ConnectorName: {
   client_id: '{add_client_id}',
   client_secret: '{add_client_secret}',
   auth_url: '{add_auth_url}',
   refresh_url: '{add_refresh_url}',
   refresh_token: '{add_refresh_token}'
   //Configure the OAuth params from the values returned after registering your app and generating authorization code in Zoho API console
  }
 });

const connector = await connector.getConnector('ConnectorName');

Async/await

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

// async/await.
try {
	const data = await connector.getAccessToken();
	// 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.

connector.getAccessToken()
	.then(
		(data) => {
			// process data.
		},
		(error) => {
			// error handling.
		}
	);

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

connector.getAccessToken()
	.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.
connector.getAccessToken(
	(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 connector.getAccessToken();
	// process data.
} catch (error) {
	const message = error.message;
	const status = error.statusCode;
	console.log({ message, status });
}
