This sample code helps get you started with a simple Express web service deployed by AWS CodeDeploy and AWS CloudFormation to an Amazon EC2 instance.
This sample includes:
- README.md - this file
- server.js - this file contains the code for your service
- appspec.yml - this file is used by AWS CodeDeploy when deploying the web service to EC2
- package.json - this file contains various metadata relevant to your Node.js service such as dependencies
- scripts/ - this directory contains scripts used by AWS CodeDeploy when installing and deploying your service on the Amazon EC2 instance
- tests/ - this directory contains unit tests for your application
- template.yml - this file contains the description of AWS resources used by AWS CloudFormation to deploy your infrastructure
- template-configuration.json - this file contains the project ARN with placeholders used for tagging resources with the project ID
These directions assume you want to develop on your local computer, and not from the Amazon EC2 instance itself. If you're on the Amazon EC2 instance, the virtual environment is already set up for you, and you can start working on the code.
To work on the sample code, you'll need to clone your project's repository to your local computer. If you haven't, do that first. You can find instructions in the AWS CodeStar user guide.
-
Install Node.js on your computer. For details on available installers visit https://nodejs.org/en/download/.
-
Install NPM dependencies:
$ npm install -
Start the development server:
$ node server.js -
Open http://127.0.0.1:3000/ in a web browser to view your service.
Once you have a virtual environment running, you can start making changes to the sample Express web service. We suggest making a small change to server.js first, so you can see how changes pushed to your project's repository are automatically picked up by your project pipeline and deployed to the Amazon EC2 instance. (You can watch the progress on your project dashboard.) Once you've seen how that works, start developing your own code, and have fun!
To run your tests locally, go to the root directory of the
sample code and run the npm test command, which
AWS CodeBuild also runs through your buildspec.yml file.
To test your new code during the release process, modify the existing tests or add tests to the tests directory. AWS CodeBuild will run the tests during the build stage of your project pipeline. You can find the test results in the AWS CodeBuild console.

To add AWS resources to your project, you'll need to edit the template.yml
file in your project's repository. You may also need to modify permissions for
your project's worker roles. After you push the template change, AWS CodeStar
and AWS CloudFormation provision the resources for you.
See the AWS CodeStar user guide for instructions to modify your template: https://docs.aws.amazon.com/codestar/latest/userguide/how-to-change-project#customize-project-template.html
AWS recommends you review the security best practices recommended by the framework author of your selected sample application before running it in production. You should also regularly review and apply any available patches or associated security advisories for dependencies used within your application.
