Components

• API Gateway front-end
• Lambda JavaScript function back-end
• DynamoDB datastore

Required AWS resources

The main.tf Terraform file contains basic resources required for DynamoDB including a table and IAM role with associated policies.

To use this install and configure Terraform for your AWS account.

API Gateway

redir-v1-swagger.yml contains a Swagger YAML definition for the front-end interface. This can be imported into your AWS using Amazon's API Gateway Importer.

NOTE: References to Amazon account id have been replaced with {{YOUR AWS ACCOUNT ID}}. You will need to change these to your numeric AWS account id.

Lambda Functions

All Lambda functions are organized under lambda using the Apex framework.

NOTE: References to Amazon account id have been replaced with {{YOUR AWS ACCOUNT ID}}. You will need to change these to your numeric AWS account id.

Once you install Apex, you can deploy via the CLI:

> cd lambda
> apex deploy

And execute locally via the CLI:

> cd lambda
> echo '{ "token":"xxxxxxx" }' | apex invoke lookup_token
