Azure SAS token generator

A simple JavaScript Azure SAS token generator

The current project is about how to programmatically generate a Shared Access Signature (SAS) token to use with Postman in order to post messages to Azure Service Bus Topic/Queue.

Motivation

After googling for a while in order to generate the necessary token, to post messages to Azure service bus, I noticed that there is no clear explanations, how to achieve it in JavaScript!! I'm proud to offer you a simple JS way to generate Azure SAS token - using node - or angular.

Features

Installation

Code Example

import { createSharedAccessToken } from 'azure-sas-token';

// default token validity is 7 days
let sasToken = createSharedAccessToken('https://<service namespace>.servicebus.windows.net/<topic name or queue>',
								'<signature key name>',
								'<signature hash>');
console.log(`sasToken: ${sasToken}`);

// Specify your own validity in secs, two hours in this example
sasToken = createSharedAccessToken('https://<service namespace>.servicebus.windows.net/<topic name or queue>',
								'<signature key name>',
								'<signature hash>', 
								60 * 60 * 2);
console.log(`sasToken: ${sasToken}`);
