## Overview

This repository is a small Node.js greeting app wrapped in an AWS CI pipeline. A developer pushes to CodeCommit; CodePipeline triggers CodeBuild, which runs the tests, packages the app, and uploads the artifact to S3. IAM permissions and CloudWatch build logs support that flow. The app also runs locally and prints a greeting. Pipeline relationships and AWS service responsibilities are based on the README; the build configuration and test implementation were not excerpted, so their detailed behavior is not independently verified.

Main entry points: [`app.js`](https://github.com/adewalekean/aws-devops-ci-project/blob/master/app.js) (Greeting App), [`app.test.js`](https://github.com/adewalekean/aws-devops-ci-project/blob/master/app.test.js) (Automated Tests), [`buildspec.yml`](https://github.com/adewalekean/aws-devops-ci-project/blob/master/buildspec.yml) (Artifact Packaging)
