This is the code example for the blog post Building Serverless Subscription Service using Lambda@Edge Our example application supports providing a custom experience for website visitors who sign in to the site, so we start by authenticating users when they navigate to the website in their browser.

• First, install the serverless framework by following the instructions at this link: https://serverless.com/framework/docs/providers/aws/guide/quick-start/

$ npm install -g serverless
$ git pull https://github.com/aws-samples/aws-serverless-subscription-service-node.git
$ cd to the repository folder
$ npm install package.json --save
$ serverless deploy -v

• In the CloudFormation console, when the application is complete, click the output URL to verify the deployment.

• In the paywall_edge_function folder, update the config.js file using the CloudFormation output.

• Update the config.js by replacing cloudfront-distro-id with your CloudFront distribution ID.

config.web.rootPath = 'https://cloudfront-distro-id.execute-api.us-east-1.amazonaws.com/dev';
config.web.hostName = 'cloudfront-distro-id.execute-api.us-east-1.amazonaws.com';
config.web.headlessCmsUrl = 'https://cloudfront-distro-id.execute-api.us-east-1.amazonaws.com/dev/articlesexportall';

• After you update the config.js file, create the Lambda zip file by using following commands:

npm install package.json --save
zip paywall.zip *

• More information about how to create a Lambda deployment package can be found in our documentation

• In the AWS Lambda console, create a new Lambda function. Use paywall.zip as the codebase for the function.

• In the CloudFront console, create a distribution following the steps in the blog post.

• Under Add triggers, choose CloudFront, and then add viewer-request triggers for /login, /api/login, and /articles by adding cache behaviors for each one. You can find step-by-step instructions in our documentation

• You can also refer the screenshots included in screenshots directory in the repository.
