swipelime-client-node

Official Node.js Client Library for swipelime.

See the API documentation for more information and example usage.

Getting the API credentials

To use the package, you'll need to have API credentials. To get an API account, please contact us.

Installation

npm i swipelime-client-node

Requirements

The package officially supports Node.js version 20 an above.

Usage

Import the package and construct a Client. The first argument is an object of your API credentials. With the second argument you can specify the environment you will connect to. You'll need to add a ServiceHandler to the client to handle the tenant.

Be careful not to expose your credentials, for example when sharing source code.

An example using async/await and ES Modules:

import { Client } from 'swipelime-client-node';

const username = 'insert-your-username-here';
const password = 'insert-your-password-here';
const client = new Client({ username, password }, { environment: 'test' });

(async () => {
    const serviceHandler = await client.addServiceHandler({ tenantId: 'insert-tenant-id-here' });
})();

This example is for demonstration purposes only. In production code, the API credentials should NOT be hard-coded, but instead fetched from a configuration file or environment variable.

You will need to add listeners to get the events or commands to process The newTasks event will be called when you receive new tasks from the swipelime API. The tasks is an array containing TaskEvent and/or TaskCommand objects.

serviceHandler.emitter.on('newTasks', (tasks) =>
{
	tasks.forEach(async (task) =>
	{
		// Process the task here
	});
})

You will receive TaskEvent task when the swipelime API is reporting that something has happened in the system. You can check the data for useful information and react to it in your system. After you done processing it you will need to confirm it with the confirm function.

if(task instanceof TaskEvent)
{
	// Test event
	if(task.data.eventType === 'test')
	{
		console.log('test event has arrived');
	}

	await task.confirm();

	console.log('test event has been confirmed');
}

You will receive TaskCommand task when the swipelime API is requesting data from your system. You will need to gather the data and call the matching function for the command type. For example if you receive the test command you will need to call serviceHandler.confirmTestCommand. You do not need to confirm the TaskCommand because calling the function will automatically does it for you.

else if(task instanceof TaskCommand)
{
	// Test command
	if(task.data.commandType === 'test')
	{
		console.log('test command has arrived');

		await serviceHandler.confirmTestCommand(task);

		console.log('test command has been confirmed');
	}
}

You have the option to just refuse to give us the information when you receive the command. This is possible by calling the task.refuse function. It is also a good idea to refuse any unknown or not implemented commands so it don't fill up the queue.

else
{
	task.refuse();
}
