Demo of using AWS API gateway with different lambda functions

API Gateway Demo

This is a small demonstration on setting up an AWS api gateway (v2) with lambda functions responding to each endpoint.

Concept

Create the following endpoints

HTTP Verb	Endpoint	payload	Return
POST	/candidates	body: JSON object of name (string), id (string), skills (string[])	none
GET	/candidates	none	array of candidates
GET	/candidates/search	query: skill="string"	array of candidates

Notes:

• This demo makes use of dynamoDB as a backend.
• The search is based on one keyword at a time

I've attached a Postman Collection to help with the testing. Please make sure to update the URL variable of the collection to the correct AWS Http API gateway URL.

Usage

Global setup

1. Ensure you have aws cli authorization, i.e., your ~/.aws/credentials exists and is valid
2. Installed globally typescript, yarn, and aws-cdk

local

1. Install modules: yarn install
2. To see what the CloudFormation template would be use cdk synth
3. Deploy to your AWS account with cdk deploy
4. Now use Postman or curl to test the endpoints
