1. Quick Start

Install the package:

npm install @avimesa/infra-api-amqp

Configure your API credentials using the following options:

1.1 Set Credentials using setConnParams

Use the setConnParams function before accessing the API:

const infraApi = require('@avimesa/infra-api-amqp');

infraApi.setConnParams({
    apiKey: '<** Enter API Key **>',
    apiPassword: '<** Enter API Password **>',
});

1.2 Load Credentials using .env file

update or add your .env file in the project root:

# API Key
API_KEY= <** Enter API Key **>

# API Password
API_PASSWORD= <** Enter API Password **>,

Load the package:

...
const infraApi = require('@avimesa/infra-api-amqp');
...

Use API per documentation, for example, listing Devices for the Group:

infraApi.listGroups(function(err, groups){
	if(!err){
		for (var i = 0; i < groups.length; i++){
			console.log(groups[i]);
		}
	}
});

2. API Reference

setConnParams

Summary

Set the connection parameters for the AMQP connection

const infraApi = require('@avimesa/infra-api-amqp');

infraApi.setConnParams({
    apiKey: '<** Enter API Key **>',
    apiPassword: '<** Enter API Password **>',
});

Note, you can override connection parameters as well:

infraApi.setConnParams({
    apiKey: '<** Enter API Key **>',
    apiPassword: '<** Enter API Password **>',
    hostname: 'rmqserv001.avimesa.com',
    port: 5671
    vhost: '<** By default, 'infrastructure' **>',
});

listGroups

Summary

Lists the Groups for the Device CLoud instance (which is specified in credentials in the .env file, or configured with the setConnParams call)

Callback

listGroups(function(err, groups){ ... })

Parameters:

The callback signature contains:

• err (boolean) - true if error, false otherwise
• groups (array) - array of group IDs in string form

Async

let response = await infraApi.listGroupsAsync();

addGroup

Summary

Callback

addGroup(apiKey, function(err, authKey, acctId){ ... })

Adds a Group to the Device Cloud. If successful, a generated API Password and Accounting ID is provided in the response.

Parameters:

• apiKey (string) - API Key (or Group Name). Lower case, 32 characters, a-f0-9.

The callback signature contains:

• err (boolean) - true if error, false otherwise
• apiPassword (string) - the 128bit authentication key (32 characters, a-f0-9)
• acctId (Number) - the unsigned 32 bit accounting ID

Notes:

• Use the validGroupId utility function

Async

let response = await infraApi.addGroupAsync(apiKey);

removeGroup

Summary

Callback

removeGroup(apiKey, function(err, msg){ ... })

Removes a Group from the Device Cloud instance. The Group must not have any Devices. Any files or data cached for this Group in the Avimesa Device Cloud will be removed and trashed.

• This may result in disabling a Group. Proceed with caution only if you know what you're doing!

Parameters:

• apiKey (string) - API Key (or Group Name). Lower case, 32 characters, a-f0-9.

The callback signature contains:

• err (boolean) - true if error, false otherwise
• msg (string) - error message if there's an error

Async

let response = await infraApi.removeGroupAsync(apiKey);

acctRecordListener

Summary

Listens to the accounting record queue.

Callback

acctRecordListener(function(err, msg){ ... })

The callback signature contains:

• err (boolean) - true if error, false otherwise
• msg (object) - JSON record with gid (Group ID (Linux)), did (Device ID), dts (Linux upload time), msg (message count for transaction), and jif (jiffy count for transaction) in the given format (for example):

{
   "gid": 413400036,
   "did": “20010db80000000002c9bffffe1c7393”,
   "dts": 1526533115,
   "msg": 8,
   “jif”: 450
}

acctRecordConsume

Summary

Consumes the records from the accounting record queue.

Callback
