Defining Constructs

This feature allows developers to define their own constructs by extending the Construct class. Constructs can encapsulate any number of child constructs and resources, providing a way to create reusable and composable infrastructure components.

{"const { Construct } = require('constructs');\n\nclass MyConstruct extends Construct {\n  constructor(scope, id) {\n    super(scope, id);\n    // Define resources and other constructs here\n  }\n}\n\nconst app = new Construct();\nconst myConstruct = new MyConstruct(app, 'MyConstructId');"}

Composing Constructs

This feature demonstrates how to compose constructs within other constructs, allowing for the creation of complex infrastructure systems by nesting constructs.

{"const { Construct } = require('constructs');\n\nclass MyConstruct extends Construct {\n  // ...\n}\n\nclass MyCompositeConstruct extends Construct {\n  constructor(scope, id) {\n    super(scope, id);\n    new MyConstruct(this, 'NestedConstruct');\n  }\n}\n\nconst app = new Construct();\nconst myComposite = new MyCompositeConstruct(app, 'MyCompositeConstructId');"}

Synthesizing Constructs

This feature shows how to synthesize a construct, which means to generate a representation of the construct's state, typically for the purpose of deploying infrastructure. The 'synthesize' method is part of the 'Node' class, which provides context and lifecycle methods for constructs.

{"const { Construct, Node } = require('constructs');\n\nclass MyConstruct extends Construct {\n  // ...\n}\n\nconst app = new Construct();\nconst myConstruct = new MyConstruct(app, 'MyConstructId');\n\nconst synthesized = Node.of(myConstruct).synthesize();\nconsole.log(synthesized);"}
