Exploring property values in an AWS CDK application using Typescript

As a newcomer to the world of Go language, I find myself passing some properties labeled props? to my CDK appstack using the signature: props?: cdk.StackProps

When I print the variable props to the console with console.log(props), I see the following expected output:

{ env: { account: '112358132134', region: 'us-west-2' } }

However, attempting something like console.log(props['env']) results in an error message:

error TS2532: Object is possibly 'undefined'.

My goal is to utilize this property for my business logic. What steps can I take to properly retrieve and make use of it?

Answer №1

The account property access may encounter issues since the env property is marked as optional.

It appears that your TypeScript settings have enabled strict null checking, causing potential TypeError during compilation.

You have the option to disable strict null checking, although it's generally recommended to keep it enabled for better code quality.

To handle the scenario where env could be undefined, you can adjust your code accordingly.

console.log(props.env?.account); // Use this if your TS version supports
// OR
console.log(props['env'] ? props['env']['account'] : undefined);
