This sample code helps get you started with a simple Node.js web application deployed by AWS CodeDeploy to an Amazon EC2 instance.
This sample includes:
- README.md - this file
- app.js - this file contains the code for your application
- appspec.yml - this file is used by AWS CodeDeploy when deploying the web application to EC2
- package.json - this file contains various metadata relevant to your Node.js application such as dependencies
- public/ - this directory contains static web assets used by your application
- scripts/ - this directory contains scripts used by AWS CodeDeploy when installing and deploying your application on the Amazon EC2 instance
- tests/ - this directory contains unit tests for your application
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 app.js -
Open http://127.0.0.1:3000/ in a web browser to view your application.
Once you have a virtual environment running, you can start making changes to the sample Node.js web application. We suggest making a small change to /public/index.html 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.
