KnownUser.V3.Cloudfront

Before getting started please read the documentation to get acquainted with edge connectors.

This repository contains two AWS lambda functions you can add to your CloudFront distribution events ViewerRequest and ViewerResponse to integrate queue-it functionality into your backend.

Installation

• Download the ViewerRequest and ViewerResponse zip files from the latest release.

• Set your CustomerId, SecretKey and API key in index.js file in ViewerRequest folder.

• Create two lambda edge functions, one for ViewerRequest and one for ViewerResponse and put the code from this repository there respectively.

Viewer Request example:

Viewer Response example:

• Define your desired CloudFront behaviours where you want to be protected by queue and set CloudFront events ViewerRequest and ViewerResponse to point to the two functions you just created.

** Please make sure the code is living in the highest level in our lambda definition as it shown here.

Using the NPM package

Install @queue-it/cloudfront and use it like this:

• In your Viewer request lambda you need to add this.

import {onClientRequest, setIntegrationDetails} from "@queue-it/cloudfront";

setIntegrationDetails("YOUR CUSTOMERID HERE", "YOUR SECRET KEY HERE", "YOUR API KEY HERE")

// Place this in the place where you handle the incoming cloudfront events.

const queueItResponse = await onClientRequest(cloudfrontEvent);
// We got a valid response, return it to the user.
if (queueItResponse.status) {
    return queueItResponse;
}

• In your Viewer response lambda you need to add this.

import {onClientResponse} from "../";

// Place this in the place where you handle the incoming cloudfront events.

const response = await onClientResponse(cloudfrontEvent);
return response;

Request body trigger (advanced)

The connector supports triggering on request body content. An example could be a POST call with specific item ID where you want end-users to queue up for. For this to work, you will need to contact queue-it support, so it can be enabled on your GO Queue-it platform account.
Once enabled, you will need to check the Include body checkbox in the Viewer request function associations. This can be done by editing your CloudFront distribution behaviors.
