Elastic Beanstalk cannot find the server.js file

Question

I'm trying to deploy my Angular application through GitHub Actions to Elastic Beanstalk. I'm using this GitHub actions for the deploying to ELB.

My problem is, the deployment is failing as the ELB cannot find the server.js file. I have tried adding server.js file into the deploy.zip file, but then it throws a different error.

I get it, it needs server.js to run, but when I download the build for the same application which is pushed to ELB using Travis CI. It doesn't throw such error and CI/CD is working just fine.

Here is the error logged by ELB (when server.js is not added to deploy.zip):

throw err;
    ^

I'm also attaching my package.json and main.yml(for CI) files.

package.json:

"version": "1.0.1",
  "scripts": {
    "ng": "ng",
    "start": "node server.js",

    "start:prod": "gulp set --env=prod && concurrently --kill-others \"node server.js\" \"npm run serve\"",
    "build": "ng build --configuration=production",
    "test": "ng test",
    "aws": "node server.js && npm run serve",
    "lint": "ng lint",
    "e2e": "ng e2e"
  },
  ...
  ...
 }

Answer 1

I figured it out finally.

We need to zip the complete root folder excluding the node_modules folder. So, in that case, I won't need any server.js and package.json included inside the dist folder.

Updated yml snippet

- name: Building application
  run: npm run build

- name: Generate deployment package
  run: zip -r deploy.zip * -x ./node_modules
