[aws-cdk-lib/pipelines] CodePipeline and FilePath Triggers

[philmod-h]

Hey!

I'm using aws-cdk-lib/pipelines package to create a codepipeline:

const pipeline = new pipelines.CodePipeline(this, 'Pipeline', {
      synth: new pipelines.ShellStep('Synth', {
        // Use a connection created using the AWS console to authenticate to GitHub
        // Other sources are available.
        input: pipelines.CodePipelineSource.connection(
          'my-org/my-app',
          'main',
          {
            connectionArn:
              'arn:aws:codestar-connections:us-east-1:222222222222:connection/7d2469ff-514a-4e4f-9003-5ca4a43cdc41', // Created using the AWS console * });',
          }
        ),
        commands: ['npm ci', 'npm run build', 'npx cdk synth'],
      }),
    });

That seems to create automatically the Source and a Git Trigger:

How could I change the Trigger to include a FilePath?

Cheers,
Mod

One solution I found is to use aws-cdk-lib/aws-codepipeline to create the underlying pipeline to use in the L3 construct:

import * as awscodepipeline from 'aws-cdk-lib/aws-codepipeline';
import { CodeBuildOptions, CodePipeline, CodePipelineSource, ShellStep } from 'aws-cdk-lib/pipelines';

const underlyingPipeline: awscodepipeline.Pipeline = new awscodepipeline.Pipeline(this, 'Pipeline', {
  pipelineName: 'pipeline',
  pipelineType: awscodepipeline.PipelineType.V2,
  triggers: [{
    providerType: awscodepipeline.ProviderType.CODE_STAR_SOURCE_CONNECTION,
    gitConfiguration: {
      sourceAction,
      pushFilter: [{
        filePathsIncludes: ['blah/*'],
        branchesIncludes: ['main'],
      }],
    },
  }],
});

const codePipeline = new CodePipeline(this, 'CodePipeline', {
  codePipeline: underlyingPipeline,
  [...]
});
