SaaS Builder Toolkit for AWS

The SaaS Builder Toolkit for AWS (SBT) is an open-source developer toolkit to implement SaaS best practices and increase developer velocity.

It offers a high-level object-oriented abstraction to define SaaS resources on AWS imperatively using the power of modern programming languages. Using SBT’s library of infrastructure constructs, you can easily encapsulate SaaS best practices in your SaaS application, and share it without worrying about boilerplate logic.

Currently, SBT is available in the following language:

• JavaScript, TypeScript (Node.js ≥ 14.15.0)
  • We recommend using a version in Active LTS

Third-party Language Deprecation: language version is only supported until its EOL (End Of Life) shared by the vendor or community and is subject to change with prior notice.

SBT is built on top of the AWS Cloud Development Kit (CDK). It offers a number of higher-order constructs (L2, L2.5 and L3) to short-circuit the time required to build SaaS applications. Specifically, SBT attempts to codify several control plane and application plane concepts into reusable components, promoting reuse and reducing boilerplate code.

Getting Started

For a detailed walkthrough, see the tutorial in the developer guide.

At a glance

Initialize a CDK project:

mkdir hello-cdk
cd hello-cdk
cdk init sample-app --language=typescript

This creates a sample project looking like this:

export class HelloCdkStack extends cdk.Stack {
  constructor(scope: cdk.App, id: string, props?: cdk.StackProps) {
    super(scope, id, props);

    const queue = new sqs.Queue(this, 'HelloCdkQueue', {
      visibilityTimeout: cdk.Duration.seconds(300)
    });

    const topic = new sns.Topic(this, 'HelloCdkTopic');

    topic.addSubscription(new subs.SqsSubscription(queue));
  }
}

Install or update SBT from npm (requires Node.js ≥ 14.15.0). We recommend using a version in Active LTS

npm install @cdklabs/[email protected]

Add a sample control plane to your application. In the HelloCdkStack add the following:

const cp = new sbt.ControlPlane(this, 'control-plane', {
  idpName: 'COGNITO',
  systemAdminRoleName: 'SystemAdmin',
  systemAdminEmail: '[email protected]',
  applicationPlaneEventSource: 'sbt-application-plane-api',
  provisioningDetailType: 'Onboarding',
  controlPlaneEventSource: 'sbt-control-plane-api',
  onboardingDetailType: 'Onboarding',
  offboardingDetailType: 'Offboarding',
});

Deploy this to your account:

cdk deploy
