How do you write buildspec.yml for use with NodeJS and AWS CodeBuild?

I have a NodeJS app that serves an Angular frontend, this app is deployed using AWS Elastic Beanstalk. If I were to directly upload a .zip file to Elastic Beanstalk, it would contain:

\dist
request-map.js
credentials.json
server.js

This is tested and worked great. But now I want a CD pipeline

When you build the Angular app (ng build), it compiles all the artifacts into a \dist folder at the root of your project. I have successfully created a continuous delivery pipeline, but to get it to work I had to commit the \dist folder to my code repository. This is obviously not ideal.

To improve my architecture, I knew I had to create a build stage. I've successfully added the build stage, and it runs fine with my buildspec.yml file, but when I navigate to my domain I get the error:

Error: ENOENT: no such file or directory, stat '/var/app/current/dist/my-angular-app/index.html'

Here is my buildspec.yml file

# Do not change version. This is the version of aws buildspec, not the version of your buldspec file.
version: 0.2
phases:
  pre_build:
    commands:
      - echo Installing source NPM dependencies...
      - npm install
  build:
    commands:
      - echo Build started on `date`
      - echo Compiling the dist folder
      - npm run-script build
  post_build:
    commands:
      - echo Build completed on `date`
# Include only the files required for your application to run.
artifacts:
  files:
    - index.js
    - dist/**/*
    - request-map.js
    - credentials.json
    - node_modules/**/*

Every other config item with respect to AWS is default.

I checked /var/app/current (where the artifacts get written) on my EC2 instance, and everything seemed to have copied over except the dist folder??? What is wrong with my setup?

Here are the logs from AWS CodeBuild

It was because I was not pointing the deploy step to the artifacts of the CodeBuild step. You will see this in CodePipeline. If you don't tell AWS what the name of your artifacts package is, it doesn't know what to deploy. You set the name of your CodeBuild artifacts/output in the CodeBuild configuration.

Make sure that your CodeBuild artifact output match your deploy artifact input

here are some step by step images to envision the required changes using the console:

1-3. To edit your CodeBuild artifact output follow these steps: enter image description here

  1. Here is the important part, name this Output artifact to some name of your choice enter image description here

  2. Edit your deploy action enter image description here

  3. Another important part, name your Input artifact to the same name from step 4 enter image description here

  4. Make sure to click 'Done' for both stages and then click 'Save' enter image description here

Thank you @Jake Chambers your answer saved my day after trying to find a solution to this problem for about 6h! I posted this answer just because your answer is a bit hard to understand and I almost gave up trying to figure out what you meant to say...

The dist folder never makes into the artifact that CodeBuild creates because you are referring to its location from root of filesystem instead of root of source directory. Please update the buildspec 'artifacts' section as follows:

artifacts:
  files:
    - index.js
    - dist/**/*
    - request-map.js
    - credentials.json
    - node_modules/**/*

This doesnt work either, I think the directory isnt being created to begin with because if I add, "test.js" to artifacts that gets copied over fine. – Osculation
please install tree and do a "tree ." as last command to inspect directory and confirm if dist dir is there – Theo
apt-get install tree – Theo
I've noticed regardless of what I put under artifacts, all of my project files are still built and deployed into the app directory. It seems that this artifacts notation is not working correctly – Osculation

Is your .gitignore file includes "dist" folder? If so, please try exclude this from your .gitignore file and try again.
