Tips for implementing accurate structure on CloudFrontWebDistribution class

I seem to be facing an issue while trying to create a new instance of the CloudFrontWebDistribution using aws-cdk v1.7. The compiler is showing some dissatisfaction with the construct I provided.

import { Stack, StackProps, Construct, App } from '@aws-cdk/core';
import { CloudFrontWebDistribution } from '@aws-cdk/aws-cloudfront';

export class MyCloudFrontStack extends Stack {

    constructor(scope: Construct, id: string, CloudFrontStackParameters, props?: StackProps) {
        super(scope, id, props);

        const env = parameters.environment.toLowerCase();
        const webDistributionConfigs = { // configurations here... };
        this.cloudFrontWebDistrubtion = new CloudFrontWebDistribution(scope, id, webDistributionConfigs); // encountering typescript errors related to the scope variable
    }
}

The TypeScript compiler is specifically pointing out a problem with the scope variable that's being passed into the constructor of CloudFrontWebDistribution.

Argument of type 'import("c:/Users/me/node_modules/@aws-cdk/core/lib/construct").Construct' is not assignable to parameter of type 'import("c:/Users/me/node_modules/@aws-cdk/aws-lambda/node_modules/@aws-cdk/core/lib/construct").Construct'. Types of property 'node' are incompatible. Property '_defaultChild' is missing in type 'import("c:/Users/me/node_modules/@aws-cdk/core/lib/construct").ConstructNode' but required in type 'import("c:/Users/me/node_modules/@aws-cdk/aws-lambda/node_modules/@aws-cdk/core/lib/construct").ConstructNode'.ts(2345) construct.d.ts(61, 13): '_defaultChild' is declared here.

Could it be a misuse of types on my end? Any suggestions on where I might have gone wrong?

Answer №1

To resolve the issue, I implemented the following solution:

import { Stack, StackProps, Construct, App } from '@aws-cdk/core';
import { CloudFrontWebDistribution } from '@aws-cdk/aws-cloudfront';

export class MyCloudFrontStack extends Stack {

    constructor(scope: Construct, id: string, CloudFrontStackParameters, props?: StackProps) {
        super(scope, id, props);

        const env = parameters.environment.toLowerCase();
        const webDistributionConfigs = { // configurations here... };
        this.cloudFrontWebDistrubtion = new CloudFrontWebDistribution(this, id, webDistributionConfigs); 
    }
}

The crucial step is to utilize the this keyword and provide it as the first argument in the 

new CloudFrontWebDistribution(...)
constructor. By doing so, the CDK understands that it should create the CloudFront web distribution for the current stack (MyCloudFrontStack) exclusively, rather than for the parent stack (represented by the scope variable).

Furthermore, explicitly specifying dependencies in the package.json file and ensuring they are all on the same version can help prevent any potential conflicts due to package versions mismatch.
