Condense Opinionated CDK Library

This library contains constructs and stacks we use across our projects.

Networking

Networking provides a VPC already configured with public, private and isolated subnets.

It requires setting a cidr or IPAM allocation, to avoid accidental usage of default CIDR.

Optionally, it also creates a bastion host.

It is available as a construct:

class MyStack extends cdk.Stack {
  constructor(scope: Construct, id :string, props?: cdk.StackProps) {
    super(scope, id, props);
    const networking = new Networking(this, 'Networking', {
      cidr: ec2.IpAddresses.cidr('10.0.0.0/16'),
    });
  }
}

or as a stack:

const app = new cdk.App();

const networking = new NetworkingStack(app, 'networking', {
  cidr: ec2.IpAddresses.cidr('10.0.0.0/16'),
})

Both of them implements the INetworking interface, allowing to easily compose your infrastructure.

Database

Supported database constructs:

• Aurora Provisioned Cluster
• RDS Instance

And their relative stack version:

• Aurora Provisioned Cluster
• RDS Instance

All of them implements the IDatabase interface, allowing to easily compose your infrastructure.

Other useful constructs

Naive BasicAuth Cloudfront Function

NaiveBasicAuthCloudfrontFunction is useful when a basic protection layer must be added to Cloudfront (for SPAs or static sites) and you just need to avoid crawlers and unwanted visitors.
