npm build (nuxt build) does not create dist folder in amplify(aws codebuild) using nuxt spa mode

Question

I want to create dist folder, after running 'npm build'(nuxt build) in amplify.

I run npm build in my local(mac) , then dist folder is created.

I run 'ls -a' after 'npm build' , then dist folder does not exist in amplify.

Answer 1

From the Nuxt documentation: https://nuxtjs.org/docs/2.x/directory-structure/dist

The dist folder, short for distribution folder. It is dynamically generated when using the nuxt generate command and includes the generated production ready HTML files and assets that are necessary to deploy and run your statically generated Nuxt.js application.

Including - npm run generate into your amplify build commands will solve this issue

version: 1
frontend:
  phases:
    preBuild:
      commands:
        - npm install
    build:
      commands:
        - npm run generate
        - npm run build
  artifacts:
    baseDirectory: dist
  ...

Answer 2

I solved it setting up the amplify.yml file. I changed baseDirectory: dist to baseDirectory: .nuxt.
