Serverless Node.js generateUpdateStatement in TypeScript

For this take home project I used a different node starter. This uses Serverless, node.js and TypeScript. I choose this starter to show how we can implement Typescript and OOP in a lambda function with serverless. This API could be deployed in AWS with a proper configuration and used as a service.

Requirements

• Install the Serverless Framework

Installation

To create a new Serverless project.

$ serverless install --url https://github.com/mtoscan/generate-update-statement-typescript --name my-project

Enter the new directory

$ cd my-project

Install the Node.js packages

$ npm install

Usage

To run a function on your local

$ serverless invoke local --function hello

To simulate API Gateway locally using serverless-offline

$ serverless offline start

Running Tests

Run tests using

$ npm test

I'm using Jest to run the tests. You can read more about setting up tests here.

List of changes or Improvements pending

• Improve type definitions to avoid use of any.
• More unit test cases
• Add environment variables
• Config serverless to deploy to AWS

Postman File

You can import the file Backend_Take_Home.postman_collection.json in your postman app. You will find a collection of post request using the same data used in the test cases. Is required to simulate the API Gateway locally with serverless offline.
