Serverless Framework Part 5: Pulling in a node package

Tue, 09 Feb 2016 11:31:00 +0100

This is the final part of an ongoing series about the Serverless framework.

In the previous posts, the PasswordGenerator always returned ‘Password’. Instead each date should corresponds to a new unique password. We’ll make use of the Crypto-js node package and we’ll see that the AWS lambda copes just fine.

Installing a node package

Pull in the crypto-js package into the serverless component.

$ cd nodejscomponent/
$ npm install crypto-js --save
crypto-js@3.1.6 node_modules/crypto-js

Now we need the typescript definitions. Watch out there are two different TypeScript typings called cryptojs and crypto-js. The first one is more complete.

Serverless Framework - Part 4: Connecting the parts

This is part of an ongoing series about the Serverless framework: Part 1, part 2, part 3.

New version 0.3.1

Edit: since the original version of this post, a new version 0.3.1 of Serverless was released. I have updated the tutorial below to reflect the newer version. Also, TSD has been deprecated in favour of Typings so I’ve updated to use Typings instead. All parts have been updated for the latest version of the framework 0.3.1.

The Password of the Day Generator class

First up we need a class to generate and check the password of the day. For the moment, let’s pretend the password of the day is always the string “Password”. Put the following typescript class in nodejscomponent/src.

Serverless Framework - Part 3: The guts of a serverless service

This is part of an ongoing series about the Serverless framework. For those following along, part 1 and part 2 have been updated for the current latest version of Serverless 0.3.1.

In this post, we’ll discuss how a Serverless function actually works.

The guts of a serverless function

When we visited the deployed endpoint at the end of part 1, it correctly returned some JSON content.

{
 message: "Your Serverless function ran successfully!"
}

Where does this message come from? Look at index.js in the component’s lib folder.

Serverless Framework - Part 2: TypeScript and Mocha

Tue, 12 Jan 2016 08:08:00 +0100

Happy New Year everyone!

This is the second part of a series about the Serverless framework. Read the first part to get up and running.

First I’ll describe the webservice I’m building. Then we’ll configure our environment for Typescript and Mocha testing.

Poor man’s dual factor authentication via a password of the day

I’m the technical lead for an enterprise application which is in use by about 100 large multinational corporates. As part of the installation process, we ask for a registration code which is based on the date. The customer has to call us to get the password of the day. This gives us an opportunity to engage with the customer and also gives us little more control. It’s a simple form of dual factor authorization where one of the factors requires a phone call.
