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.

Installation

npm install azure-sas-token

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}`);

Angular bonus application [not delivered into the npm package itself]

If you prefer a simplier way to get fastly a token, you could use my angular application azure-sas-token from here:
https://ah584d.github.io/azure-sas-token/

This is the same application of the 'angular' folder, you can use the online version, or to checkout the repository and run it locally on your computer.

cd azure-sas-token/angular
npm install
npm run start

POST https://<yournamespace>.servicebus.windows.net/<yourentity>/messages
Content-Type: application/json
Authorization: SharedAccessSignature sr=https%3A%2F%2F<yournamespace>.servicebus.windows.net%2F<yourentity>&sig=<your token generated by this repository code>&se=1438205742&skn=KeyName

The application is totally safe, nothing is saved on third party, no request is sent outside, everything is handled in client side
